reports available to holders of interests in the Offered Notes in accordance
with the rules, regulations and procedures creating and affecting DTC. However,
such reports will not be sent directly to each beneficial owner while the
Offered Notes are in book-entry form. Upon the issuance of fully registered,
certificated Offered Notes, such reports will be sent directly to each
Noteholder. Such reports will not constitute financial statements prepared in
accordance with generally accepted accounting principles. The Trust Manager, on
behalf of the Issuer Trustee, will file with the Securities and Exchange
Commission (the "Commission") such periodic reports as are required under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules
and regulations of the Commission thereunder. However, in accordance with the
Exchange Act and the rules and regulations of the Commission thereunder, the
Trust Manager expects that the Issuer Trustee's obligation to file such reports
will be terminated following the end of 1998.
 
   
          DISCLAIMERS WITH RESPECT TO LISTING ON LONDON STOCK EXCHANGE
    
 
   
    This section applies only to the offer to subscribe for, or purchase, the
Offered Notes in any country outside the United States of America. The Issuer
Trustee's responsibility for, and liability in respect of, this Prospectus is
limited accordingly.
    
 
    This Prospectus does not constitute an offer of, or an invitation by or on
behalf of, the Issuer Trustee or the Underwriters or any of them, to subscribe
for or purchase any of the Offered Notes, and must not be relied upon by anybody
intending to purchase the Offered Notes.
 
   
    No action has been or will be taken by the Issuer Trustee or the
Underwriters that would permit a public offer of the Offered Notes in any
country or jurisdiction (other than in the United States of America) where
action for that purpose is required. Accordingly, the Offered Notes may not be
offered or sold, directly or indirectly, and neither this Prospectus nor any
offering circular, prospectus, form of application, advertisment or other
offering material may be issued or distributed or published in any country or
jurisdiction, except in circumstances that will result in compliance with all
applicable laws and regulations and the Underwriters have represented that all
offers and sales by them have been and will be made on such terms. Persons into
whose possession this document comes are required by the Issuer Trustee and the
Underwriters to inform themselves about and to observe any such restrictions.
[For a description of certain further restrictions on offers and sales of
Offered Notes and distribution of this document as to non-US beneficial

contained herein. No representation, warranty or undertaking, express or
implied, is made and no responsibility or liability is accepted by the Currency
Swap Providers as to the accuracy or completeness of any of the information in

supplied in connection with the Offered Notes or their distribution.
    
 
   
    None of the Seller Trustee, the Servicer, Westpac, the Security Trustee, the
Note Trustee or the Underwriters accepts any responsibility for any information

information contained herein. No representation, warranty or undertaking,
express or implied, is made and no responsibility or liability is accepted by
the Seller Trustee, the Servicer, the Trust Manager, Westpac, the Security
Trustee, the Note Trustee or the Underwriters as to the accuracy or completeness
of any information contained in this Prospectus or any other information

receiving this Prospectus acknowledges that such person has not relied on the
Seller Trustee, the Servicer, the Trust Manager, Westpac, the Security Trustee,
the Note Trustee or the Underwriters nor on any person affiliated with any of
them in connection with its investigation of the accuracy of such information or
its investment decisions.
    
 
   
    No person has been authorised to give any information or to make any
representations other than those contained in this Prospectus and the documents
incorporated by reference herein in connection with the issue or sale of the
Offered Notes and, if given or made, such information or representation must not
be relied upon as having been authorised by the Issuer Trustee or any of the
Underwriters. Neither the delivery of this Prospectus nor any sale made in
connection herewith shall, under any circumstances, create any implication that
there has been no change in the affairs of the Issuer Trustee since the date
hereof or the date upon which this document has been most recently amended or
supplemented or that there has been no adverse change in the financial position
of the Issuer Trustee since the date hereof or the date upon which this document
has been most recently amended or supplemented or that any other information
supplied in connection with the Notes is correct as of any time subsequent to
the date on which it is supplied or, if different, the date indicated in the
document containing the same. The Underwriters expressly do not undertake to
review the financial condition or affairs of the Issuer Trustee during the life
of the Notes.
    
 
   
    Neither this Prospectus nor any other information supplied in connection
with the Offered Notes is intended to provide the basis of any credit or other
evaluation and should not be considered as a recommendation by the Issuer
Trustee or any of the Underwriters that any receipt of this Prospectus, or any
other information supplied in connection with the Offered Notes, should purchase
any of the Offered Notes. Each investor contemplating purchasing any of the
Offered Notes should make its own independent investigation of the financial
condition and affairs, and its own appraisal of the creditworthiness of the
Issuer Trustee and each investor should seek its own tax, accounting and legal
advice as to the consequences of investing in any of the Offered Notes and none
of the Servicer, the Seller Trustee, Westpac, the Note Trustee, the Security
Trustee or any of the Underwriters accept any responsibility or make any
representation as to the tax consequences of investing in the Notes.
    
 
   
    The Issuer Trustee's liability to make payments in respect of the Offered
Notes is limited to its right of indemnity from the assets of the Trust which
are from time to time available for this purpose pursuant to the Master Trust
Deed, the Series Notice and the Security Trust Deed. All claims against the
Issuer Trustee in relation to the Offered Notes may only be satisfied out of the
assets of the Trust, and are limited in recourse to the assets of the Trust.
    
 
    Each Noteholder is required to accept any distribution of moneys under the
Security Trust Deed in full and final satisfaction of all moneys owing to it,
and any debt represented by any shortfall that exists after any such final
distribution is extinguished. The Issuer Trustee shall not be liable to satisfy
any obligations or liabilities in relation to the Offered Notes from its
personal assets except arising from (and to the extent of ) any fraud,
negligence or breach of trust on the part of the Issuer Trustee.

                 ENFORCEMENT OF FOREIGN JUDGMENTS IN AUSTRALIA
 
   
    The Trust Manager is an Australian proprietary company incorporated with
limited liability under the Corporations Law. Any final and conclusive judgment
of any New York State or United States Federal Court sitting in the Borough of
Manhattan in the City of New York having jurisdiction recognized by the relevant
Australian jurisdiction in respect of an obligation of the Trust Manager in
respect of an Offered Note, which is for a fixed sum of money and which has not
been stayed or satisfied in full, would be enforceable by action against the
Trust Manager in the courts of the relevant Australian jurisdiction without a
re-examination of the merits of the issues determined by the proceedings in the
New York State or United States Federal Court, as applicable, unless: (a) the
proceedings in New York State or United States Federal Court, as applicable,
involved a denial of the principles of natural justice; (b) the judgment is
contrary to the public policy of the relevant Australian jurisdiction; (c) the
judgment was obtained by fraud or duress or was based on a clear mistake of
fact; (d) the judgment is a penal or revenue judgment; or (e) there has been a
prior judgment in another court between the same parties concerning the same
issues as are dealt with in the judgment of the New York State or United States
Federal Court, as applicable. A judgment by a court may be given in some cases
only in Australian dollars. The Trust Manager has expressly submitted to the
jurisdiction of New York State and United States Federal Courts sitting in the
Borough of Manhattan in the City of New York for the purpose of any suit, action
or proceedings arising out of this offering. The Trust Manager has appointed
Lewis E. Love, Jr., its Director and Secretary, 575 Fifth Avenue, 39th Floor,
New York, New York 10017-2422, as its agent upon whom process may be served in
any such action.
    
 
    The majority of the directors and executive officers of the Trust Manager,
and certain experts named herein, reside outside the United States (in the
Commonwealth of Australia). Substantially all or a substantial portion of the
assets of all or many of such persons are located outside the United States. As
a result, it may not be possible for holders of the Offered Notes to effect
service of process within the United States upon such persons or to enforce
against them judgments obtained in United States courts predicated upon the
civil liability provisions of Federal securities laws of the United States. The
Trust Manager has been advised by its Australian counsel Allen Allen & Hemsley,
that, based on the restrictions referred to above, there is doubt as to the
enforceability in the Commonwealth of Australia, in original actions or in
actions for enforcement of judgments of United States courts, of civil
liabilities predicated upon the Federal securities laws of the United States.
 
                       EXCHANGE CONTROLS AND LIMITATIONS
 
    Under temporary Australian foreign exchange controls, payments by an
Australian resident to, or on behalf of: (a) the Government of Iraq or its
agencies or nationals; (b) the authorities of the Federal
 
                                       6
<PAGE>
Republic of Yugoslavia (Serbia and Montenegro); or (c) the Government of Libya
or any public authority or controlled entity of the Government of Libya may only
be made with Reserve Bank of Australia approval. Such restrictions may change in
the future. See "RISK FACTORS--Risks of Currency Exchange Controls."
 
                            U.S. DOLLAR PRESENTATION
 
    In this Prospectus, references to "U.S. dollars" and "US$" are references to
U.S. currency and references to "Australian dollars" and "A$" are references to
Australian currency. Unless otherwise stated herein, the translations of
Australian dollars into U.S. dollars have been made at a rate of US$[ ]=A$1.00,
the noon buying rate in New York City for cable transfers in Australian dollars
as certified for customs purposes by the Federal Reserve Bank of New York on
      , 1998. Use of such rate is not a representation that Australian dollar
amounts actually represent such U.S. dollar amounts or could be converted into
U.S. dollars at that rate.

                                  Embankment, London, EC4Y OJP, will act as a paying agent

                                  Agent, the "Paying Agents").
 
Roles of the Security Trustee
  and Note Trustee..............  The structure of the Series 1998-1G WST Trust transaction
                                  employs several different trustees. The Security Trustee
                                  is the entity that holds a security interest over the
                                  assets of the Trust and has the responsibility of securing
                                  such assets and distributing the proceeds received upon
                                  the liquidation of such assets upon the occurrence of a
                                  default and enforcement of the security interest. The Note
                                  Trustee is the entity which represents the interest of the
                                  Noteholders. The provisions of the Security Trust Deed
                                  require the Security Trustee to consult with, and obtain
                                  the consent of, the Note Trustee before taking certain
                                  actions. Thus, not only does the Security Trustee owe
                                  fiduciary duties to the Note Trustee (and the Offered
                                  Noteholders and the other secured creditors), it has
                                  contractual obligations to consult and act at the Note
                                  Trustee's direction in accordance with the Security Trust
                                  Deed. The Note Trustee owes fiduciary duties to the
                                  Offered Noteholders and must act in accordance with those
                                  duties when directing the Security Trustee to act or not
                                  to act. The roles of the Note Trustee and the Security
                                  Trustee together approximate the role of an Indenture
                                  Trustee in a United States transaction.
 
Securities Offered..............  The Issuer Trustee, in its capacity as trustee of the
                                  Series 1998-1G WST Trust, which was formed under
                                  Australian law, will issue and hereby offer the following
                                  Mortgage Backed Floating Rate Notes:
 
                                  Class A Mortgage Backed Floating Rate Notes due       in
                                  the aggregate principal amount of US$      (the "Class A
                                  Notes").
 
                                  Class B Mortgage Backed Floating Rate Notes due       in
                                  the aggregate principal amount of US$      (the "Class B

                                  of Offered Notes will be made quarterly on the 19th day of
                                  each of April, July, October and January (or if such 19th
                                  day is not a Business Day, the next succeeding Business
                                  Day in the same month or, if not in the same month, the

                                  20, 1998 (each such date, a "Payment Date").
 
                                  As used in this Prospectus, "Business Day" means any day,
                                  other than a Saturday, Sunday or public holiday, on which
                                  banks in Sydney, London, New York City, the city in which
                                  the corporate trust office of the paying agent is located
                                  and the city in which the office of the Swap Providers are
                                  open. If a public holiday is occurring in any of the
                                  referenced locales, then such day is not a Business Day,
                                  and no scheduled payments will be made on such day.
 
                                  Payments of interest and principal will be made to the
                                  holders of the Offered Notes (the "Offered Noteholders")
                                  of record as of the day which is two Business Days
                                  preceding the Payment Date (so long as the Offered Notes
                                  are held in book-entry form) or the last day of the prior
                                  calendar month (if Definitive Notes have been issued)
                                  (such day, the "Record Date"). Each Offered Note bears
                                  interest on its Invested Amount. The "Invested Amount" of
                                  an Offered Note is equal to the Initial Invested Amount
                                  (as defined herein) of such Offered Note less all payments
                                  previously made in respect of principal in respect of such
                                  Offered Note. The "Initial Invested Amount" of a Class of
                                  Notes is its principal balance on the date of its
                                  issuance. Each "Interest Period" (other than the initial
                                  Interest Period and the final Interest Period) with

                                  Date. The initial Interest Period with respect to the

                                  and ends on (but excludes) the first Payment Date. The

                                  "USD-LIBOR-Reference Banks" means that the rate for an
                                  Interest Period will be determined on the basis of the

                                  payments due to such holders and to provide holders of the

                                  of any unrepaid Principal Draws on such Payment Date. The
                                  application of such amounts, if any, will reduce the
                                  likelihood of the Offered Noteholders receiving less than
                                  their Initial Invested Amount on or prior to the Maturity
                                  Date.

                                  payments of Interest on each Payment Date will be
                                  subordinated to such rights of the holders of the RFSs (if
                                  any), Class A Notes, RFS Class A Notes (if any) and the
                                  Redraw Facility Provider to the extent set forth herein.
                                  In addition, the rights of the holders of the Class B
                                  Notes to receive distributions of principal on each
                                  Payment Date generally will be subordinated to such rights
                                  of the holders of the RFSs (if any) and the Redraw
                                  Facility Provider with respect to repayments pursuant to
                                  the Redraw Facility Agreement and to the holders of the
                                  Class A Notes and RFS Class A Notes (if any). For a
                                  description of the priority among the RFSs, Class A Notes,

                                  Principal Charge Offs will be applied first in reduction
                                  of the principal balance of the Class B Notes. The
                                  subordination described above is intended to enhance the
                                  likelihood of regular receipt by the holders of the Class
                                  A Notes of the full amount of interest and principal
                                  payments due to such Noteholders and to afford such

                                  Trustee in its capacity as trustee of the Trust only (and
                                  therefore the Issuer Trustee's liability to make payments
                                  of interest and principal on the Offered Notes is limited
                                  to the collections received by the Issuer Trustee from the
                                  Trust Assets) and except in certain limited circumstances
                                  are not the personal obligation of the Issuer Trustee. See
                                  "THE ISSUER TRUSTEE--Limitation of Issuer Trustee's
                                  Liability." They are issued with the benefit of, and
                                  subject to the Transaction Documents. The Issuer Trustee's
                                  liability in respect of the Offered Notes is limited to
                                  the assets of the Trust available in accordance with the
                                  terms of the Transaction Documents to meet its obligations
                                  in relation to the Offered Notes and, except in certain
                                  limited circumstances, the Issuer Trustee will not be
                                  personally liable in respect of the Offered Notes.
 
  A. The Housing Loans..........  The Housing Loans will consist of       Housing Loans with
                                  an aggregate Balance Outstanding on the Cut-Off Date of
                                  A$      . The Housing Loans are also referred to herein as
                                  the "Mortgage Pool." The Housing Loans will be secured by
                                  Mortgaged Properties (as defined herein) located in any of
                                  the six states or two territories of Australia. A
                                  "Mortgaged Property" means the land, including all
                                  improvements thereon, that is the subject of a Mortgage.
 
                                  Each Housing Loan is secured by a registered first ranking
                                  mortgage over the related Mortgaged Property. "Registered"
                                  means the mortgage has been filed with the lands office in
                                  the relevant Australian State or Territory, granting
                                  certain rights with respect to the applicable Mortgaged
                                  Property. See "APPENDIX I--GLOSSARY OF AUSTRALIAN LEGAL
                                  TERMS."
 
                                  Each Housing Loan requires that borrowers on such Housing
                                  Loan (each, a "Borrower") make a minimum payment (the
                                  "Scheduled Payment") on or before the due date for such
                                  Scheduled Payment under the relevant Housing Loan
                                  documents. Scheduled Payments not received with respect to
                                  certain Housing Loans on the related due date may cause
                                  either a default rate of interest to be charged or a
                                  compounding interest effect.
 
                                  All weighted averages specified herein are weighted based
                                  on the Cut-Off Date Balances Outstanding of the Housing
                                  Loans. With respect to each Housing Loan, the "Cut-Off
                                  Date Balance Outstanding" is the unpaid principal balance
                                  of such Housing Loan as of the close of business on the
                                  Cut-Off Date. All Housing Loan statistics set forth herein
                                  are based on principal balances, interest rates, terms to
                                  maturity, mortgage loan counts and similar statistics as
                                  of the Cut-Off Date, unless indicated to the contrary
                                  herein. References to percentages of the Housing Loans
                                  mean percentages of the Cut-Off Date Balance Outstanding.
 
                                  The Housing Loans bear interest at variable and fixed
                                  rates (the "Mortgage Rates") which, as of the Cut-Off
                                  Date, range from

                                  approximately       to       . The weighted average
                                  Mortgage Rate of the Housing Loans on the Cut-Off Date is
                                  approximately    % per annum. The Cut-Off Date Balances
                                  Outstanding of the Housing Loans ranged from approximately
                                  A$      to A$      . The average Cut-Off Date Balance
                                  Outstanding of the Housing Loans is approximately
                                  A$      . The weighted average original term to stated
                                  maturity of the Housing Loans was approximately   months.
                                  The weighted average remaining term to stated maturity of
                                  the Housing Loans was approximately   months. As of the
                                  Cut-Off Date, the weighted average number of months that
                                  had elapsed since origination of the Housing Loans is
                                  approximately   months.
 
                                  Housing Loans representing approximately    % of the
                                  Cut-Off Date Pool Balance are secured by Mortgaged
                                  Properties which are investment properties (based solely
                                  upon statements made by the related Mortgagors at the time
                                  of origination of the related Housing Loans).
 
                                  The lowest and highest LVR as of the Cut-Off Date of the
                                  Housing Loans were approximately    % and    %. LVR is
                                  calculated as a fraction, expressed as a percentage, the
                                  numerator of which is the outstanding amount of the
                                  Housing Loan, plus any other amount serviced on the
                                  Servicing System of the Servicer (the "Mortgage Servicing
                                  System") and secured by the relevant Mortgage Property at
                                  the Cut-Off Date and the denominator of which is the
                                  aggregate value of the Mortgaged Property subject to the
                                  related Mortgage for that Housing Loan.

                                  Collection Determination Date that the Available Income
                                  (as defined herein) of the Trust for a Collection Period
                                  is insufficient to meet Total Payments of the Trust on the
                                  following Payment Date (a "Payment Shortfall"), then
                                  Principal Collections collected during that Collection
                                  Period can be used to fund the Payment Shortfall (a
                                  "Principal Draw"). See "DESCRIPTION OF THE OFFERED
                                  NOTES--Principal Draws" below.

                                  out of that Excess Available Income for the relevant
                                  period. If there is insufficient Excess Available Income
                                  to reimburse Principal Draws, the principal repayable on
                                  the Notes at maturity may be reduced in respect of such
                                  shortfall.
 
                                  2. LIQUIDITY FACILITY: Under the Liquidity Facility,
                                  Westpac in its capacity as the provider of the Liquidity
                                  Facility (the "Liquidity Facility Provider") agrees to
                                  make advances to the Issuer Trustee for the purpose of
                                  funding certain income shortfalls in the Trust, up to an
                                  aggregate amount being the lesser of: (1) A$      , (2)
                                  the Unpaid Balance of all Performing Loans from time to
                                  time, and (3) any lesser amount as is agreed in writing
                                  between the Liquidity Facility Provider, the Issuer
                                  Trustee, the Trust Manager and the Rating Agencies, as
                                  such amount may be reduced or cancelled under the
                                  Liquidity Facility (the "Liquidity Limit"). The "Unpaid
                                  Balance" of a Housing Loan, means the sum of (a) the
                                  unpaid principal amount of that Housing Loan; and (b) the
                                  unpaid amount of all finance charges, interest payments
                                  and other amounts accrued on or payable under or in
                                  connection with that Housing Loan or the related Mortgage
                                  or other rights relating to the Housing Loan.
 
                                  A "Performing Loan" at any date is a Housing Loan which is
                                  not Delinquent or has been Delinquent for less than 90
                                  consecutive days, or if it has been Delinquent for 90 or
                                  more consecutive days, was insured under a Mortgage
                                  Insurance Policy at the date of the Liquidity Facility. A
                                  Housing Loan is "Delinquent" if the related Borrower fails
                                  to pay any amount due on the related due date. Delayed
                                  payments arising from agreed payment holidays based on
                                  early repayments, or from maternity or paternity leave
                                  repayment reductions will not, by themselves, lead to a
                                  Housing Loan being considered Delinquent. See "WESTPAC
                                  RESIDENTIAL LOAN PROGRAM--Housing Loan Features" and "THE

                                  The Issuer Trustee will grant a "floating charge" over the
                                  Trust Assets to the Security Trustee in order to secure
                                  the Issuer Trustee's obligations in respect of the Notes
                                  and the Transaction Documents. A "charge" is a proprietary
                                  interest created over property. A floating charge is a
                                  grant of a security interest which "floats" over a group
                                  of assets which assets may change or be dealt with from
                                  time to time. A floating charge allows the person or
                                  entity granting the charge (the "chargor") to deal with
                                  the assets and to give third parties title to those assets
                                  free from any encumbrance. For a description of a floating
                                  charge and the crystallization of floating charges, see

Clean-up Offer..................  If at any time the aggregate Housing Loan Principal,
                                  expressed as a percentage of the aggregate Housing Loan
                                  Principal as of the Cut-Off Date, is less than 10%, then,
                                  if instructed by the Trust Manager, the Seller Trustee, as
                                  trustee of certain other trusts under the Master Trust
                                  Deed, may repurchase, on the following Payment Date, the
                                  equitable title to the Housing Loans held by the Trust for
                                  an amount equal to the Unpaid Balance (in the case of
                                  performing Housing Loans) or the Fair Market Value (in the
                                  case of non-performing Housing Loans) (the "Clean-up
                                  Offer"). The proceeds of sale will be applied by the
                                  Issuer Trustee to repay moneys owing to Noteholders at
                                  that time in accordance with the priorities for applying
                                  payments of Interest and principal between the Classes of
                                  Notes. With respect to any Housing Loan and date, "Housing
                                  Loan Principal" shall be the unpaid principal amount of
                                  that Housing Loan on such date. "Unpaid Balance" of a
                                  Housing Loan, means the sum of (a) the unpaid principal
                                  amount of that Housing Loan; and (b) the unpaid amount of
                                  all finance charges, interest payments and other amounts
                                  accrued on or payable under or in connection with that
                                  Housing Loan or the related Mortgage or other rights
                                  relating to the Housing Loan. The "Fair Market Value" with
                                  respect to any non-performing Housing Loans is the fair
                                  market value of such Housing Loan agreed on by the Trust
                                  Manager (based on appropriate expert advice) and the
                                  Approved Seller.

Legal Investment
  Considerations................  The Offered Notes will not constitute "mortgage related
                                  securities" for purposes of the Secondary Mortgage Market
                                  Enhancement Act of 1984 ("SMMEA"). No representation is
                                  made as to whether the Offered Notes constitute legal
                                  investments under any applicable statute, law, rule,
                                  regulation or order for any entity whose investment
                                  activities are subject to investment laws and regulations
                                  or to review by certain regulatory authorities.
                                  Prospective purchasers are urged to consult with their
                                  counsel concerning the status of the Offered Notes as
                                  legal investments for such purchasers. See "LEGAL
                                  INVESTMENT CONSIDERATIONS" herein.
 
Tax Status......................  In the opinion of Mayer, Brown & Platt, special tax
                                  counsel for the Trust, the Offered Notes will be
                                  characterized as debt for U.S. federal income tax purposes
                                  and the Trust will not be characterized as an association
                                  (or a publicly traded partnership) taxable as a
                                  corporation for federal income tax purposes. Each Offered
                                  Noteholder, by acceptance of an Offered Note, will agree
                                  to treat the Offered Notes as indebtedness. See "CERTAIN
                                  UNITED STATES FEDERAL INCOME TAX CONSEQUENCES" herein.
 
                                  Payments of principal and Interest in respect of the
                                  Offered Notes will be made subject to withholding tax (if
                                  any) applicable to the Offered Notes without the Issuer
                                  Trustee being obliged to pay any additional amounts to the
                                  Noteholders in respect of such withholding tax.

                                  CONSIDERATIONS," the Offered Notes are eligible for

Ratings of the Offered Notes....  It is a condition to the issuance of the Class A Notes
                                  that they be rated "AAA" by Standard & Poor's Ratings
                                  Group, a division of The McGraw-Hill Companies ("Standard
                                  & Poor's"), "Aaa" by Moody's Investors Service, Inc.

                                  issuance of the Class B Notes that they be rated "AA-" by
                                  Standard & Poor's and "AA-" by Fitch. The security ratings
                                  of the Offered Notes should be evaluated independently
                                  from similar ratings on other types of securities. A
                                  security rating is not a recommendation to buy, sell or
                                  hold securities and may be subject to revision or
                                  withdrawal at any time by the Rating Agencies. See

                               CASH FLOW SUMMARY
 
    THE FOLLOWING IS A BRIEF SUMMARY OF THE ALLOCATION OF CASHFLOWS IN RELATION
TO THE TRUST. THIS CASH FLOW SUMMARY IS QUALIFIED IN ITS ENTIRETY BY REFERENCE
TO THE DETAILED INFORMATION APPEARING ELSEWHERE IN THIS PROSPECTUS --SEE
"DESCRIPTION OF THE OFFERED NOTES" FOR A FULL DESCRIPTION OF CASHFLOW
ALLOCATION. TERMS DEFINED BELOW ARE DEFINED IN MORE DETAIL ELSEWHERE--THE
DEFINITIONS BELOW ARE FOR CONVENIENCE ONLY.
 
COLLECTIONS
 
    Amounts collected by or on behalf of the Issuer Trustee in respect of the
Trust are calculated for each Collection Period and include, for the relevant
Collection Period:
 
    1.  scheduled payments (of interest, principal and fees) and prepayments of
principal under the Housing Loans;
 
    2.  proceeds from enforcement of Housing Loans and related Mortgages (see
"CERTAIN LEGAL ASPECTS OF THE HOUSING LOANS--Enforcement of Housing Loans");
 
    3.  amounts payable under Mortgage Insurance Policies with respect to losses
on Housing Loans and related Mortgages;
 
    4.  amounts received from an Approved Seller or the Servicer for breaches of
representations or undertakings; and
 
    5.  interest on amounts in the Collections Account.
 
   
    These amounts are known as "Collections," which will be attributed between
income and principal. The Collections attributed to income, less certain
amounts, are "Available Income". The Collections attributed to principal, less
certain amounts, are "Gross Principal Collections".
    
 
   
    The cashflow allocation methodology treats Available Income and Gross
Principal Collections in two separate "streams." Generally, the two streams are
treated separately. However, in some circumstances, principal will be treated as
income and applied in the income stream, and in other circumstances income will
be treated as principal and applied in the principal stream.
    
 
GROSS PRINCIPAL COLLECTIONS
 
   
    Gross Principal Collections are applied first to repay Westpac for any
Redraws funded by Westpac in the relevant Collection Period. The balance of
Gross Principal Collections remaining after such repayment of Westpac is known
as "Principal Collections." Those Principal Collections are applied:
    
 
    1.  First, to repay Westpac for any Redraws funded by Westpac to the extent
not previously reimbursed (I.E., not restricted to Redraws funded during the
relevant Collection Period);
 
    2.  Second, to repay amounts outstanding under the Redraw Facility
Agreement;
 
    3.  Third, to be treated as income to the extent necessary if there is
insufficient income for the Collection Period to make required income payments
(this application of principal as income is a "Principal Draw");
 
    4.  Fourth, to pay principal outstanding under the RFSs until repaid in
full;
 
    5.  Fifth, to pay principal outstanding under the Class A Notes and the RFS
Class A Notes. Those payments may be applied either sequentially or serially
with respect to Class B Notes, depending on whether certain threshold tests have
been satisfied.
 
    Initially all Principal Collections will be applied "sequentially," meaning
that such Principal Collections will be applied to the RFSs (if any), Class A
Notes and RFS Class A Notes (if any), pro rata, until such classes are paid in
full. The Class B Notes are then entitled to Principal Collections.
 
                                       29
<PAGE>
   
    If certain distribution tests have been met, Principal Collections will be
applied "serially", entitling the Class A Notes and the Class B Notes to share
in Principal Collections. There are two serial distribution tests which focus on
whether the subordination provided by the Class B Notes to the Class A Notes
effectively doubles from the initial level of subordination at the start of the
transaction, whether the distribution of Principal Collections is occurring
prior to a certain date and whether certain credit tests focusing on
delinquencies and losses on the Housing Loans have been met. For a complete
description of the serial distribution tests, see the definitions of "Serial
Method 1 Distribution Test" and "Series Method 2 Distribution Test" set forth in
"DESCRIPTION OF THE OFFERED NOTES--Payments of Principal on the Notes."
    
 
    6.  Sixth, to pay principal outstanding under the Class B Notes under the
sequential or serial methods referred to above.
 
PRINCIPAL LOSSES
 
    It may be that principal losses are incurred in respect of a Housing Loan
during a Collection Period.
 
    If (i) a Borrower defaults; (ii) the relevant Housing Loan and related
Mortgage are enforced; and (iii) the amount recovered (after payment of
enforcement expenses) will not satisfy the Unpaid Balance of the Housing Loan,
there will be a "Liquidation Loss". A Liquidation Loss will usually comprise
both income and principal. To the extent that it relates to principal, a
Liquidation Loss is known as a "Principal Loss". If, following a Principal Loss,
the relevant Mortgage Insurance Policy does not cover that loss and the Issuer
Trustee does not have a right to recover any amounts from an Approved Seller or
the Servicer due to a breach of representation or undertaking, there will be a
loss on the underlying principal in the pool. Such a loss is a "Mortgage
Shortfall". The total amount of all Mortgage Shortfalls in a Collection Period
is known as the "Principal Charge Off" for that Collection Period.
 
    Any Principal Charge Off for a Collection Period may be met by any excess
income which is available from the income stream for that purpose (as summarized
below). If the Principal Charge Off cannot be satisfied in full from that excess
income, the principal loss represented by the balance of the Principal Charge
Off which is not so satisfied must be "carried over" into succeeding periods.
This is a "Carryover Charge Off".
 
    Each Carryover Charge Off must be represented by a reduction in the
principal amount of the Notes. Thus, the principal amount of the Notes (the
"Invested Amount") is reduced:
 
        (a) First, in respect of Class B Notes; and
 
        (b) Second, if the Class B Notes are reduced to zero, PRO RATA, in
    respect of the Class A Notes, the RFSs, the RFS Class A Notes and the Redraw
    Facility Agreement.
 
    The "Stated Amount" of a Note is thus the Invested Amount of the Note less
the Carryover Charge Offs applied against it as set out above.
 
    Excess income may be used to recover principal which has been reduced
following a Carryover Charge Off. The application of income for this purpose is
summarized below.
 
INCOME COLLECTIONS
 
    Available Income is applied in the following order of priority:
 
   
        (a) First, in respect of the first Collection Period, to the Approved
    Seller for income received by the Issuer Trustee on the pool relating to the
    period prior to the Closing Date. This is the "Accrued Interest Adjustment";
    
 
   
        (b) Second, to Trust Expenses which have not previously been paid;
    
 
                                       30
<PAGE>
   
        (c) Third, to repay amounts outstanding under the Support Facilities
    (other than the Currency Swap and fees under the Liquidity Facility
    Agreement);
    
 
   
        (d) Fourth, to repay Liquidity Draws under the Liquidity Facility
    Agreement;
    
 
   
        (e) Fifth, PARI PASSU and ratably, to interest on the Class A Notes, the
    RFSs and the RFS Class A Notes and to fees under the Redraw Facility
    Agreement; and
    
 
   
        (f) Sixth, to interest on the Class B Notes.
    
 
    These payments are "Total Payments".
 
    Any Available Income in excess of Total Payments for a Collection Period is
"Excess Available Income", and is applied in the following order of priority:
 
        (i) First, against Principal Charge Offs for the Collection Period;
 
        (ii) Second, PARI PASSU and ratably, against Carryover Charge Offs for
    Class A Notes, RFSs, RFS Class A Notes and fees or amounts owing under the
    Redraw Facility Agreement;
 
       (iii) Third, against Carryover Charge Offs for Class B Notes; and
 
        (iv) Fourth, to Principal Draws which have not previously been repaid.
 
    Any amount remaining after application of these payments is an "Excess
Collections Distribution", and will be paid to Westpac as beneficiary of the
Trust.
 
LIQUIDITY SUPPORT
 
    If there are insufficient interest Collections to meet Total Payments for a
Collection Period, principal may be used to provide liquidity by way of a
"Principal Draw" (see above).
 
    If Principal Draws are not available to meet Total Payments, a drawing must
be made under the Liquidity Facility Agreement up to its facility limit (being
A$      ) to provide liquidity to allow Total Payments to be made.
 
CURRENCY SWAP
 
   
    All payments required to be made to Noteholders will be made in Australian
dollars to the Currency Swap Providers, who will swap the amounts into US
dollars.

                                  RISK FACTORS
 
    In addition to the matters described elsewhere in this Prospectus,
prospective investors should carefully consider the following factors before
deciding to invest in the Offered Notes.
 
LIMITED LIABILITY UNDER THE OFFERED NOTES
 
    The Offered Notes are debt obligations of the Issuer Trustee in its capacity
as trustee of the Trust. They are issued with the benefit of, and subject to the
Master Trust Deed, the Series Notice, the Security Trust Deed and the Note Trust
Deed. The Issuer Trustee's liability in respect of the Offered Notes is limited
to the assets of the Trust available in accordance with the terms of the Master
Trust Deed, the Series Notice, the Note Trust Deed and the Security Trust Deed
to meet its obligations in relation to the Offered Notes and, except in certain
limited circumstances, the Issuer Trustee will not be personally liable in
respect of the Offered Notes. See "THE ISSUER TRUSTEE--Limitation of Issuer
Trustee's Liability."
 
    In addition, the Offered Notes will not represent an interest in or
obligation of the Servicer, the Trust Manager, the Approved Sellers, the Note
Trustee, the Security Trustee or any of their respective affiliates (other than
the Issuer Trustee to the extent referred to above). The only obligations of the
foregoing entities with respect to the Offered Notes or any Housing Loan will be
the obligations of the Approved Sellers pursuant to certain limited
representations and warranties made with respect to the Housing Loans, of the
Servicer with respect to its servicing obligations under the Servicing Agreement
and the Trust Manager in respect of its undertakings in the Transaction
Documents. The Offered Notes will not be guaranteed or insured by any
governmental agency or instrumentality, or by the Issuer Trustee, the Servicer,
the Trust Manager, the Approved Sellers, the Note Trustee, the Security Trustee
or any of their respective affiliates. The Housing Loans are subject to certain
mortgage insurance policies, but only limited losses are covered. Housing Loans
insured by HLIC prior to December 12, 1997 will have the benefit of a
Commonwealth Government Guarantee. See "THE MORTGAGE INSURANCE POLICIES."
Proceeds of the assets included in the Trust (including the Housing Loans) will
be the sole source of payments on the Offered Notes, and there will be no
recourse to the Servicer, the Trust Manager, the Approved Sellers, the Note
Trustee, the Security Trustee or any other entity in the event that such
proceeds are insufficient or otherwise unavailable to make all payments provided
for under the Offered Notes.
 
   
RISK OF EQUITABLE ASSIGNMENT OF HOUSING LOANS RATHER THAN LEGAL ASSIGNMENT
    
 
   
    Although the Housing Loans and the related Mortgages could have been legally
assigned by the Seller Trustee to the Issuer Trustee, they will initially only
be equitably assigned until a Title Perfection Event (as defined below) occurs.
A "Title Perfection Event" in relation to the Housing Loans is the occurrence of
any of the following: (i) Westpac ceases to have a long term credit rating of at
least "BBB" from Standard & Poor's, "Baa2" from Moody's; and "BBB" from Fitch
(ii) an Insolvency Event occurs with respect to Westpac; and (iii) Westpac fails
to transfer Collections within five Business Days after receiving notice from
the Issuer Trustee or the Trust Manager to do so. Until such time, pursuant to
the Transaction Documents, the Issuer Trustee is not permitted to take any steps
to perfect legal title and it cannot, and will not, notify the Borrowers of the
equitable assignment of the Housing Loans to the Issuer Trustee. If a Title
Perfection Event occurs, the Issuer Trustee, with the assistance of the
Servicer, is required take such steps as are necessary to perfect the Issuer
Trustee's legal title in the Housing Loans.
    
 
    The delay in the notification to a Borrower of the assignment of the Housing
Loans to the Issuer Trustee may have the following consequences:
 
    (1) until a Borrower has notice of the assignment, that Borrower is not
bound to make payments under the relevant Housing Loan to anyone other than
Westpac and can obtain a valid discharge from Westpac. However, the Servicer, a
delegate of Westpac, will act as the initial Servicer of the Housing Loans and
is obligated to deal with all moneys received from the Borrowers in accordance
with the Servicing Agreement and the Master Trust Deed;
 
    (2) for so long as the Issuer Trustee holds only an equitable interest in
the Housing Loans, the Issuer Trustee's interest in them may become subject to
the interests of third parties created after the creation of
 
                                       34
<PAGE>
the Issuer Trustee's equitable interest but prior to it acquiring a legal
interest in the Housing Loans. However, the Servicer undertakes not to consent
to the creation or existence of any higher or equal ranking security interest
over the Mortgaged Property (the "Servicer's Security Undertaking"); and
 
    (3) for so long as the Issuer Trustee holds only an equitable interest in
the Housing Loans, it must join Westpac as a party to any legal proceedings
against any Borrower in relation to the enforcement of any Housing Loan. In this
regard, Westpac undertakes in the Servicing Agreement to co-operate with the
Servicer in connection with the enforcement of any Housing Loans. Westpac has
granted an irrevocable power of attorney to the Issuer Trustee to perfect its
interest in the Housing Loans.
 
    So long as the Issuer Trustee holds equitable title, rather than legal
title, to a Housing Loan, the Issuer Trustee's interest in such Housing Loan may
be impaired by the creation or existence of any higher or equal ranking security
interest over the related Mortgaged Property if the Servicer fails to adhere to
the Servicer's Security Undertaking. Such failure may result in losses to
Noteholders.
 
RISK OF LOSSES AND DELAYS FROM ENFORCEMENT OF THE HOUSING LOANS
 
   
    Substantial delays could be encountered in connection with the liquidation
of a Housing Loan and result in shortfalls in distributions to Noteholders to
the extent not covered by a Mortgage Insurance Policy or if the relevant
Mortgage Insurance Policy provider fails to perform its obligations. Further,
liquidation expenses such as legal fees, real estate taxes, and maintenance and
preservation expenses (to the extent not covered by a Mortgage Insurance Policy)
will reduce the net amounts recoverable by the Issuer Trustee from an enforced
Housing Loan and mortgage and will reduce Excess Available Income. In the event
any of the Mortgaged Properties fail to provide adequate security for the
related Housing Loans, Noteholders could experience a loss to the extent not
covered by a Mortgage Insurance Policy or if the relevant Mortgage Insurance
Policy provider fails to perform its obligations and the subordination of Excess
Available Income is not sufficient.
    
 
   
MORTGAGE INSURANCE POLICIES ARE SUBJECT TO EXCLUSIONS AND LIMITATIONS
    
 
   
    The liability of each of the Mortgage Insurers under the Mortgage Pool
Insurance Policy and the PMI Policies, as applicable, is subject to certain
exclusions. Each of them also has the right to cancel the coverage of, or
terminate its Mortgage Insurance Policy in respect of, a Housing Loan in certain
circumstances. The exclusions and rights vary among the different Mortgage
Insurance Policies and may affect the ability of the Issuer Trustee to make
timely and full payments of principal and Interest on the Notes. See "THE
MORTGAGE INSURANCE POLICIES" for further details.
    
 
RISKS ASSOCIATED WITH HIGH LVR HOUSING LOANS
 
    Approximately    % of the Housing Loans by aggregate principal balance of
the related Housing Loans as of the CutOff Date, had an LVR in excess of 80%.
Housing Loans with higher LVRs may present a greater risk of delinquency.
Although each Housing Loan in the Trust with an LVR in excess of 80% is covered
by a PMI Policy which insures the full amount of the Unpaid Balance of the
related Housing Loan, if a Borrower fails to make payments under such a Housing
Loan and the applicable Mortgage Insurer cancels the relevant PMI Policy,
reduces the amount of a claim or fails to honor its obligation under the PMI
Policy, proceeds from a liquidation of such Housing Loan may be insufficient to
cover the Unpaid Balance thereof. As a result, Noteholders may experience losses
including Principal Charge Offs (as defined herein) with respect to the Offered
Notes. For a description of such coverage, see "THE MORTGAGE INSURANCE
POLICIES."
 
   
RISKS ASSOCIATED WITH WESTPAC'S ABILITY TO SET RATES ON VARIABLE RATE HOUSING
  LOANS AT ITS DISCRETION
    
 
    The interest rates with respect to the Variable Rate Housing Loans are not
tied to an objective interest index but rather may be set at the sole discretion
of Westpac, as originator of the Housing Loans. See "WESTPAC RESIDENTIAL LOAN
PROGRAM--Housing Loan Features." In the event that Westpac increases interest
rates on the Variable Rate Housing Loans, Borrowers may be unable to meet
 
                                       35
<PAGE>
their Scheduled Payment and accordingly, may be delinquent or default on their
respective Housing Loans. In addition, if such increase raises interest rates
above market interest rates, Borrowers may refinance their loans with another
lender to obtain a lower interest rate, which in turn could cause investors in
the Offered Notes to experience higher rates of principal prepayment on the
Offered Notes than anticipated.
 
ABILITY TO CHANGE HOUSING LOAN FEATURES MAY RESULT IN CHANGES TO THE MORTGAGE
POOL AND HIGHER RATES OF PRINCIPAL PREPAYMENT ON THE OFFERED NOTES.
 
   
    During the term of any Housing Loan, Westpac may from time to time or at the
request of the related Borrower change certain features of such Housing Loan. A
Borrower may request, among other changes, (a) additional funds with respect to
its Housing Loan (a "top up"), (b) a substitution or modification of the
security for the related Mortgage, (c) a switch to another type of Housing Loan
product, (d) a draw on principal repayments made in excess of scheduled
repayments (a "Redraw"), (e) an interest rate switch from variable to fixed or
vice versa, (f) reduced payments due to maternity or paternity leave, (g) a
repayment holiday if a prepayment of certain amounts has resulted in a buffer of
funds and (h) a switch from owner occupied or investment property status (which
may result in a change in interest rates). For a more detailed discussion of the
various features available to Borrowers, see "WESTPAC RESIDENTIAL LOAN PROGRAM--
Housing Loan Features."
    
 
    In addition, Westpac may initiate certain changes to the Housing Loans. Most
frequently, Westpac will change the Mortgage Rate. The change to the Mortgage
Rate can be either product or individual loan specific. In addition, subject to
certain conditions, Westpac may begin to offer additional product features with
respect to the Housing Loans which are not set forth herein. See "WESTPAC
RESIDENTIAL LOAN PROGRAM-Housing Loan Features-Additional Features."
 
   
    As a result of both Borrower and Westpac initiated changes, the
characteristics of the Housing Loans as of the Cut-Off Date may differ from the
characteristics of the Housing Loans at any other point in time. In addition,
certain types of modifications to a Housing Loan result in the removal of such
Housing Loan from the Mortgage Pool, which in turn could cause investors in the
Offered Notes to experience higher rates of principal prepayment on the Offered
Notes than anticipated. Similarly, if Westpac elects to change certain features
of the Housing Loans, Borrowers may elect to refinance their loan with another
lender to obtain more favorable features, which also could lead to higher
principal prepayment on the Offered Notes than expected. See " PRINCIPAL PAYMENT
AND YIELD CONSIDERATIONS."
    
 
RISKS OF CURRENCY EXCHANGE CONTROLS
 
   
    The Issuer Trustee will receive Australian dollar payments on the Housing
Loans in Australia and, under the Currency Swap, is required to pay certain
collections to the Currency Swap Providers as required under the Series Notice.
It is possible that in the future Australia may impose exchange controls that
affect the availability of Australian dollar payments for making payments under
the Currency Swap. The Noteholders will bear the risk of the imposition of
foreign exchange controls by the Australian government that impact upon the
Issuer Trustee's ability to exchange the Collections for U.S. dollars. The
Issuer Trustee has no control over such risk, which will generally be affected
by economic and political events in Australia. If the Issuer Trustee does not
pay some or all of the amounts in Australian dollars which it is required by the
Transaction Documents to pay to the Currency Swap Providers under the Currency
Swap, the Currency Swap Providers are only required to pay the U.S. dollar
equivalent of the amounts they actually receive. In such event, it is unlikely
that the Trust would have sufficient U.S. dollars to make the payments due on
the Offered Notes.
    
 
RISKS RELATED TO A TERMINATION OF THE SWAP AGREEMENTS
 
   
    By entering into the Swap Agreements, the Trust intends to transfer to the
Interest Rate Swap Provider and Currency Swap Providers, as applicable, the
risks set forth below that the Trust would otherwise have with respect to the
Offered Notes and the Housing Loans.
    
 
                                       36
<PAGE>
   
    (a) Currency Exchange Risk. Interest and principal on the Offered Notes is
payable in U.S. dollars and the Trust's primary source for funding its payments
on the Offered Notes is its collections on the Housing Loans, which will be in
Australian dollars. If the Currency Swap Providers were to fail to perform under
the Currency Swap or were to be discharged from such performance because of a
default thereunder by the Trust, the Trust might have to exchange its Australian
dollars for U.S. dollars at an exchange rate that is less favorable to the Trust
than the original Swap Currency Exchange Rate (which is       Australian dollars
for each U.S. dollar) and might therefore not have sufficient U.S. dollars to
make timely payments on the Offered Notes, even though the delinquency and loss
experience on the Housing Loans may be acceptable.
    
 
   
    (b) Risks Specific to the Variable Rate Basis Swap. The basis risk between
the floating rate obligations of the Trust (including Interest payable on the
Notes) and the variable administered rates set by Westpac will be hedged by
means of the Variable Rate Basis Swap. Pursuant to the Variable Rate Basis Swap,
each quarter the Interest Rate Swap Provider will pay the Trust the three month
Bank Bill Rate plus a fixed margin and receive from the Trust the weighted
average variable housing rate. The margin is fixed for the life of the swap and
has been set having regard for the ongoing expenses of the Trust.
    
 
   
    If Westpac is downgraded below A1+/A2/F-1+ and fails to provide eligible
collateral or arrange for a suitable alternative swap provider, it will be an
Additional Termination Event under the terms of the ISDA Master Agreement. If
the Variable Rate Basis Swap is terminated, the Trust Manager is required to
calculate each month the minimum interest rate required to be set on the
variable rate Housing Loans in order to cover amounts payable by the Issuer
Trustee (including anticipated Trust Expenses and taxes) and amounts due to the
Issuer Trustee, the Trust Manager, the Servicer, the Liquidity Facility
Provider, the Redraw Facility Provider and the Noteholders (the "Threshold
Rate"). In this situation, THE HOUSING LOAN RATES MAY BE SET AT ABOVE MARKET
INTEREST RATES ON THE VARIABLE HOUSING LOANS TO MEET TRUST EXPENSES WHICH COULD
RESULT IN THE AFFECTED BORROWERS REFINANCING THEIR LOANS WITH ANOTHER BANK,
WHICH IN TURN COULD CAUSE NOTEHOLDERS TO EXPERIENCE HIGHER RATES OF PRINCIPAL
REPAYMENT ON THE OFFERED NOTES THAN ANTICIPATED.
    
 
   
    (c) Risks Specific to the Fixed Rate Swaps. Two Fixed Rate Swaps will be
used to hedge the interest rate risk between the floating rate obligations of
the Trust (including Interest payable on the Notes) and the discretionary fixed
rate set by Westpac on those Housing Loans being charged a fixed rate of
interest (a "Fixed Rate") (not including those loans with a Concessional Fixed
Rate). A Housing Loan is being charged a "Concessional Fixed Rate" when it has a
fixed rate of interest for the first 12 months, which converts to the standard
variable rate after that period. Loans subject to a Concessional Fixed Rate are
included under the Variable Rate Basis Swap. An amortizing Fixed Rate Swap will
be entered into as at Closing Date to hedge that portion of the pool earning a
Fixed Rate of interest as at Cutoff Date. The Issuer Trustee will pay the
applicable daily weighted average fixed rate and receive the three month Bank
Bill Rate plus a fixed margin. The margin is fixed for the life of the swap and
has been set based on the actual margin on the underlying Fixed Rate Housing
Loans and the prevailing market rate existing on or about the Closing Date. A
further Fixed Rate Basis Swap will be entered into to hedge the interest rate
risk occurring when the Borrowers switch from a variable rate of interest to a
fixed rate of interest. Under that second Fixed Rate Basis Swap, the Issuer
Trustee will pay the applicable daily weighted average fixed rate and receive
the three month Bank Bill Rate plus a fixed margin. The margin is fixed for the
life of the swap.
    
 
   
    If Westpac is downgraded below A1+/A2/F-1+ and fails to provide eligible
collateral or arrange for a suitable alternative swap provider, it will be an
Additional Termination Event under the terms of the ISDA Master Agreement ONLY
AT THE DISCRETION OF THE ISSUER TRUSTEE AT THE DIRECTION OF THE TRUST MANAGER.
IF THE SWAP REMAINS IN PLACE, THE RATING AGENCIES MAY CONSIDER DOWNGRADING THE
OFFERED NOTES AND AN INVESTOR MAY THEN BE HOLDING OFFERED NOTES WHICH HAVE BEEN
DOWNGRADED. IF THE SWAP IS TERMINATED, THE INVESTOR IS EXPOSED TO THE RISK OF
THE POSSIBLE NARROWING OF THE SPREAD BETWEEN THE CUSTOMER RATE APPLICABLE ON THE
HOUSING LOANS AND THE FLOATING RATE OBLIGATIONS OF THE TRUST (INCLUDING THE
INTEREST ON THE NOTES).

DELINQUENCY AND DEFAULT RISK
 
    If Borrowers fail to make Scheduled Payments under Housing Loans when due
there is a possibility that the Issuer Trustee may have insufficient funds to
make full payments of Interest and principal due to the Noteholders.
 
    The Issuer Trustee's obligation to pay principal in respect of the Offered
Notes in full is limited by reference to, among other things, receipts by the
Issuer Trustee of amounts due under or in respect of the outstanding Housing
Loans. Noteholders must rely for payment of principal and interest under the
Offered Notes on Borrowers making payments under the Housing Loans and on
amounts being available under the Mortgage Insurance Policies and any amounts
payable by an Approved Seller or the Servicer in respect of any breach of a
representation and warranty or undertaking respectively and, in addition, in the
case of Interest, on receipts of principal and required payments under the
Liquidity Facility. Furthermore, the Issuer Trustee is not required to make any
advances to cover shortfalls. See "DESCRIPTION OF THE OFFERED NOTES" and "THE
LIQUIDITY FACILITY."
 
    A wide variety of factors of a legal, economic, political or other nature
could affect the performance of Borrowers in making payments of principal and
interest under the Housing Loans. In particular, if interest rates increase
significantly, Borrowers may experience distress and increased default rates on
the Housing Loans may result. Under the Consumer Credit Legislation (as defined
herein), among other remedies, a court may order a Housing Loan to be varied on
the grounds of hardship. See "CERTAIN LEGAL ASPECTS OF THE HOUSING LOANS." Any
such variance may reduce the principal or interest payable under a particular
Housing Loan.
 
    If a Borrower defaults on payments under a Housing Loan and the Servicer
enforces the Housing Loan and takes possession of the relevant Mortgaged
Property, many factors may affect the price for which the Mortgaged Property is
sold and the length of time required to realize the proceeds of sale. Any delay,
and any loss incurred as a result of the realized proceeds of the sale of a
Mortgaged Property being less than the amount due under the Housing Loan, may
affect the ability of the Issuer Trustee to make payments, or the timing of
those payments, in respect of the Offered Notes, notwithstanding any amounts
that may be claimed under a Mortgage Insurance Policy or otherwise allocated
from Principal Collections or drawn under the Liquidity Facility.
 
RISK OF EARLY DEFAULTS
 
    No more than    % of the Housing Loans were originated within       months
prior to the Cut-Off Date. The weighted average remaining term to stated
maturity of such Housing Loans (by Cut-Off Date Balance Outstanding) is
approximately       months. Although little data is available and no empirical
verification has been made by the Registrant, the Underwriters or the Issuer
Trustee, defaults on mortgage loans, including mortgage loans similar to the
Housing Loans, are generally expected to occur with greater frequency in the
early years of the terms of mortgage loans.
 
   
PRINCIPAL PAYMENT AND YIELD CONSIDERATIONS
    
 
    The yield to maturity experienced by a Noteholder may be affected by the
rate of payment of principal of the Housing Loans. The Trust may receive early
payments of principal on the Housing Loans and, therefore, pay Principal
Collections to the Noteholders earlier than would otherwise have been the case.
For example, early payments of principal may occur in the following situations:
 
    (1) receipt by the Issuer Trustee of enforcement proceeds due to a Borrower
having defaulted on its Housing Loan;
 
    (2) receipt by the Issuer Trustee of insurance proceeds in relation to a
claim under a Mortgage Insurance Policy in respect of a Housing Loan;
 
    (3) repurchase by Westpac of Housing Loans as a result of a breach by it of
certain representations (see "THE TRUST FUND--Representations and Warranties"
and "--Breach of Representations and Warranties");
 
                                       38
<PAGE>
    (4) receipt by the Trust of any net amount attributable to principal from
another WST trust established under the Master Trust Deed with respect to the
substitution of a Housing Loan;
 
    (5) repurchase of the Housing Loans as a result of a Clean-Up Offer (see
"DESCRIPTION OF THE OFFERED NOTES--Clean-Up Offer");
 
    (6) receipt of proceeds of enforcement of the Security Trust Deed prior to
the Maturity Date of the Notes (see "DESCRIPTION OF THE OFFERED
NOTES--Redemption of the Notes"); or
 
    (7) receipt of proceeds of the sale of Housing Loans if the Trust is
terminated while Notes are outstanding (for example, if required by law) and the
Housing Loans are then either (a) repurchased by Westpac under its right of
first refusal or (b) sold to a third party.
 
   
    Additionally, in certain limited circumstances (for example, if the
principal amount of a Housing Loan is increased other than as a result of a
Redraw (see "DESCRIPTION OF THE OFFERED NOTES-- Description of the Redraw
Facility, the Redraw Funding Securities and the Class A RFS Notes")), the Issuer
Trustee may transfer Housing Loans which comprise assets of the Trust to another
WST trust established under the Master Trust Deed. The consideration for that
transfer, to the extent it constitutes principal, will form part of Gross
Principal Collections (as defined herein) during the related Collection Period
and will be distributed as if it were a prepayment of principal by the relevant
Borrower.
    
 
   
    Also, the Trust's principal payment experience may be affected by a wide
variety of factors, including general economic conditions, interest rates, the
availability of alternative financing, homeowner mobility and the non
tax-deductibility of interest on owner-occupied housing (see "CERTAIN LEGAL
ASPECTS OF THE HOUSING LOANS--Treatment of Interest Payments with respect to
Australian Housing Loans").
    
 
REINVESTMENT RISK
 
   
    The Interest Rate Swap Agreements transfer the reinvestment risk detailed
below to the applicable Swap Provider. In the event that the Variable Rate Basis
Swap is terminated, the reinvestment risk will transfer back to the Issuer
Trustee. If a prepayment is received on a Housing Loan during any Collection
Period, interest at the then current interest rate on the Housing Loan will
cease to accrue on that part of the Housing Loan prepaid from the date of the
prepayment. The amount prepaid will be invested in Authorized Investments for
the balance of the Collection Period at a rate that may be less than the then
rate on the Housing Loan. Interest will, however, continue to be payable in
respect of an Invested Amount of principal on the Offered Notes until the next
Payment Date following the prepayment. Accordingly, the difference between the
rate earned on the prepaid amount of the Housing Loan and the amount of interest
payable on the Offered Notes may affect the ability of the Issuer Trustee to pay
interest in full on the Offered Notes. Certain Principal Collections and the
Liquidity Facility may cover such shortfalls in whole or in part but there is no
assurance that sufficient amounts will be available. For further details see
"DESCRIPTION OF THE OFFERED NOTES--Available Income" and "--Principal Draws."
    
 
SERVICER RISK
 
    The appointment of the Servicer under the Master Trust Deed and Servicing
Agreement may be terminated under certain circumstances or the Servicer may
resign (see "DESCRIPTION OF THE SERVICING AGREEMENT"). If the Servicer is
removed for any reason, the Issuer Trustee is obligated to appoint a suitably
qualified person as Servicer whose appointment would not materially prejudice
the interests of Noteholders (an "Eligible Servicer") to assume responsibility
for servicing the Housing Loans in accordance with the Master Trust Deed and the
Servicing Agreement. There is no guarantee (a) that an Eligible Servicer will be
found who would be willing to service the Housing Loans on the terms of the
Master Trust Deed and the Servicing Agreement, in which case the Issuer Trustee
must act as the Eligible Servicer or (b) that an Eligible Servicer will be able
to service the Housing Loans with the same level of skill and competence as the
initial Servicer. The ability of the Eligible Servicer (whether it is the Issuer
Trustee or a third party) to perform the servicing functions under the Master
Trust Deed and Servicing Agreement would depend on the information and records
available to it.
 
                                       39
<PAGE>
PRIORITY OF RFSS AND RFS CLASS A NOTES OWNED BY AUSTRALIAN RESIDENT INVESTORS
 
   
    In certain limited circumstances, the Trust will issue RFSs and RFS Class A
Notes, which will be issued to Australian resident investors only. The RFSs will
be senior to the Class A Notes with respect to payments of principal and which
will rank PARI PASSU with the Class A Notes with respect to Interest. In
addition, on each Payment Date, Gross Principal Collections will be used to
reimburse Westpac for any Redraws funded by Westpac during the related
Collection Period prior to payments to the Class A Notes. Additionally, if RFS,
are not repaid on the fifth Collection Determination Date following the date
such RFSs were issued, such RFSs will convert to RFS Class A Notes. The RFS
Class A Notes will rank PARI PASSU with the Class A Notes with respect to
payments of both principal and Interest. In addition, payments due on the Redraw
Facility, RFSs and RFS Class A Notes, if any, will be senior in right of payment
to the Class B Notes with respect to principal, Interest and fees. If proceeds
from the liquidation of the assets included in the Trust following the
enforcement of the Security Trust Deed are not sufficient to pay all obligations
of the Issuer Trustee in its capacity as trustee of the Trust, Noteholders with
a lower priority of payment are at a greater risk for losses on their
investment. See "DESCRIPTION OF THE OFFERED NOTES--Description of the Redraw
Facility, the Redraw Funding Securities and the RFS Class A Notes."
    
 
CREDIT ENHANCEMENT PROVIDES ONLY LIMITED PROTECTION AGAINST LOSSES
 
   
    Credit enhancement with respect to the Class A Notes will be provided by (i)
the Mortgage Insurance Policies, (ii) subordination of the Excess Available
Income and (iii) the subordination of payments of the Class B Notes to payments
to the Class A Notes. Credit enhancement with respect to the Class B Notes will
be provided by (i) the Mortgage Insurance Policies and (ii) subordination of the
Excess Available Income. Although the credit enhancement is intended to reduce
the risk of delinquent payments or losses to the Noteholders entitled to the
benefit thereof, the amount of such enhancement is limited, will decline and
could be depleted under certain circumstances prior to the payment in full of
the Offered Notes. As a result, the available credit enhancement may be
insufficient to reduce the risk of delinquent payments of losses to the
Noteholders. See "THE MORTGAGE INSURANCE POLICIES" and "DESCRIPTION OF THE
NOTES."
    
 
LIMITATIONS ON THE LIQUIDITY SUPPORT
 
   
    If on any Collection Determination Date, the Available Income of the Trust
is insufficient to meet Total Payments of the Trust for a Collection Period,
Principal Collections collected during such Collection Period may be used to
provide liquidity by way of a Principal Draw. If Principal Draws are not
available to meet Total Payments, a drawing must be made under the Liquidity
Facility up to the Liquidity Limit (as defined herein). In the event that there
are shortfalls in excess of the Liquidity Limit prior to the payment in full of
the Offered Notes, Noteholders may suffer losses. In addition, the Liquidity
Facility is not designed to provide any credit enhancement with respect to the
Offered Notes. See "DESCRIPTION OF THE OFFERED NOTES--Principal Draws" and "THE
LIQUIDITY FACILITY."
    
 
   
EXERCISE OF CLEAN-UP OFFER MAY RESULT IN SHORTFALLS TO NOTEHOLDERS
    
 
   
    If at any time the aggregate Housing Loan Principal, expressed as a
percentage of the aggregate Housing Loan Principal as of the Cut-Off Date, is
less than 10%, then, if instructed by the Trust Manager, the Seller Trustee may
repurchase, on the following Payment Date, the equitable title to the Housing
Loans held by the Trust. The proceeds of sale will be applied by the Issuer
Trustee to repay moneys owing to Noteholders at that time in accordance with the
priorities for applying payments of Interest and principal between the Classes
of Notes. In the event that a Housing Loan is non-performing, the purchase price
for such Housing Loan will be based on the Fair Market Value. Fair Market Value
with respect to a Housing Loan may be less than the Unpaid Balance of such
Housing Loan. If a significant number of Housing Loans are non-performing, the
total proceeds from exercising the Clean-up Offer may be less than amounts owing
to Noteholders and Noteholders may suffer losses.
    
 
                                       40
<PAGE>
REDEMPTION OF THE NOTES
 
    If an Event of Default occurs under the Security Trust Deed while the Notes
are outstanding, the Security Trustee may (subject to the prior written consent
of the Note Trustee in accordance with the provisions of the Security Trust
Deed), and will (if so directed by the Note Trustee alone where it is the only
Voting Mortgagee or, otherwise by a resolution of 75% of the Voting Mortgagees)
enforce the security created by the Security Trust Deed. That enforcement can
include the sale of some or all of the Housing Loans. There is no guarantee that
the Security Trustee will be able to sell the Housing Loans for their then
Unpaid Balance. Accordingly, the Security Trustee may not be able to realize the
full value of the Housing Loans and this may have an impact upon the Issuer
Trustee's ability to repay all amounts outstanding in relation to the Notes. Any
proceeds from the enforcement of the security will be applied in accordance with
the order of priority of payments as set out in the Security Trust Deed. See
"SECURITY FOR THE NOTES."
 
    If the Trust terminates while Notes are outstanding, Westpac has a right of
first refusal to acquire the Housing Loans. The price to be paid by Westpac for
performing and non-performing Housing Loans must be not less than their fair
market value. In the case of performing Housing Loans, the Issuer Trustee is
required to offer to sell them to Westpac under its right of first refusal for
their then Unpaid Balance. Where the fair market value of a Housing Loan is less
than its then Unpaid Balance, its acquisition by Westpac will be subject to
prior approval by an Extraordinary Resolution (as defined herein) of
Noteholders. This is because in such circumstances there may be a shortfall in
the amount available to the Issuer Trustee to fully repay all amounts
outstanding in relation to the Notes. See "DESCRIPTION OF THE OFFERED
NOTES--Termination of the Trust."
 
GEOGRAPHIC CONCENTRATION MAY AFFECT PERFORMANCE
 
    Approximately    %,    % and    % (by Cut-Off Date Principal Balance) of the
Housing Loans are secured by Mortgaged Properties in the regions of New South
Wales, Victoria and Queensland, respectively. To the extent that one or more of
such regions has experienced or may experience in the future weaker economic
conditions or greater rates of decline in real estate values than Australia
generally, such a concentration of the Housing Loans may be expected to increase
the risk of delinquencies and losses on the Housing Loans with respect to such
region. None of the Issuer Trustee, the Approved Sellers nor the Servicer can
quantify the impact of any recent property value declines on the Housing Loans
or predict whether, to what extent or for how long such declines may continue.
 
CONSUMER CREDIT LEGISLATION
 
    Some of the Housing Loans are regulated by consumer credit legislation (the
"Consumer Credit Legislation"). Under that legislation, a Borrower may have a
right to apply to a court to:
 
        (1) vary the terms of his or her Housing Loan on the grounds of hardship
    or that it is an unjust contract;
 
        (2) reduce or cancel any interest rate payable on the Housing Loan which
    is unconscionable;
 
        (3) have certain provisions of the Housing Loan or relevant Mortgage
    which are in breach of the legislation declared unenforceable; or
 
        (4) obtain restitution or compensation from the Issuer Trustee, in
    relation to any breaches of the Consumer Credit Legislation in relation to
    the Housing Loan or relevant Mortgage.
 
    Any such order may affect the timing or amount of interest or principal
payments or repayments under the relevant Housing Loan (which might in turn
affect the timing or amount of interest or principal payments or repayments
under the Offered Notes).
 
                                       41
<PAGE>
    In addition, a mortgagee's ability to enforce a mortgage which is subject to
the Consumer Credit Legislation is limited by various demand and notice
procedures which are required to be followed. For example, as a general rule
enforcement cannot occur unless the relevant default is not remedied within 30
days after a default notice is given. Borrowers may also be entitled to initiate
negotiations with the mortgagee for a postponement of enforcement proceedings.
Such procedures and negotiations may also affect the timing or amount of
interest or principal payments or repayments under the Housing Loans.
 
    Breaches of the Consumer Credit Legislation may also lead to civil penalties
or criminal fines being imposed on Westpac, for so long as it holds legal title
to the Housing Loans and the Mortgages. If the Issuer Trustee acquires legal
title, it will then become primarily responsible for compliance with the
Consumer Credit Legislation. The Issuer Trustee will (subject to limited
exceptions) be indemnified out of the assets of the Trust for its liabilities
under the Consumer Credit Legislation. If the Issuer Trustee is indemnified with
respect to such liabilities out of the assets of the Trust, proceeds of the
Trust may be insufficient to make all payments provided for under the Offered
Notes.
 
    Westpac will give, or has given, certain representations and warranties that
the Housing Loans and related Mortgages comply in all material respects with the
Consumer Credit Legislation in force at the time documents were entered into.
The representation and warranties are set forth in "THE TRUST
FUND--Representations and Warranties." The Servicer has undertaken to comply
with the Consumer Credit Legislation in connection with servicing the Housing
Loans and related Mortgages where failure to do so would have an Adverse Effect.
An "Adverse Effect" is an event which will materially and adversely affect the
amount of any payment to be made to any Noteholder, or will materially and
adversely affect the timing of such payment. In certain circumstances the Issuer
Trustee may have the right to claim damages from Westpac or the Servicer, as the
case may be, where the Issuer Trustee suffers loss in connection with a breach
of the Consumer Credit Legislation which is caused by a breach of a relevant
representation or undertaking. See "CERTAIN LEGAL ASPECTS OF THE HOUSING LOANS."
 
RISK OF COMMINGLING
 
   
    Collections under the Housing Loans are received by Westpac or the Servicer.
As described in "DESCRIPTION OF THE OFFERED NOTES--Collections," provided
Westpac has a short term rating of at least "A-1+" from Standard & Poor's, "P-1"
from Moody's and "F-1+" from Fitch and the Collections Account is maintained
with Westpac or a subsidiary of Westpac, neither Westpac nor the Servicer is
required to pay the Collections into the Collections Account until two (2)
Business Days before the relevant Payment Date. If Westpac does not have the
relevant rating, Collections must be paid into the Collections Account within
five (5) Business Days (if the Collection Account is with Westpac or one of its
subsidiaries) or two (2) Business Days (in any other case) following receipt. In
each of these circumstances, the Collections may be commingled with the assets
of the Servicer or Westpac (as the case may be) and, in the event of the
insolvency of Westpac or the Servicer (as relevant), the Issuer Trustee may only
be able to claim those Collections as an unsecured creditor of the insolvent
company.
    
 
LIMITED LIQUIDITY
 
    There will be no market for the Offered Notes prior to the issuance thereof,
and there can be no assurance that a secondary market will develop, or if it
does develop, that it will provide the Noteholders with liquidity of investment
or that it will remain for the term of any Notes. The Underwriters presently
expect to make a secondary market in the Offered Notes, but have no obligation
to do so.
 
RATINGS OF THE NOTES; FACTORS AFFECTING ABILITY TO MAINTAIN RATINGS
 
   
    It is a condition to the issuance of the Class A Notes that they be rated
"Aaa" by Moody's, "AAA" by Standard & Poor's and "AAA" by Fitch that the Class B
Notes be rated at least "AA-" by Standard & Poor's and "AA-" by Fitch. A rating
is not a recommendation to purchase, hold or sell the Offered Notes,
    
 
                                       42
<PAGE>
   
inasmuch as such rating does not comment as to market price or suitability for a
particular investor. The rating of the Offered Notes addresses the likelihood of
the payment of principal and interest on the Offered Notes pursuant to their
terms. There is no assurance that a rating will remain for any given period of
time or that a rating will not be lowered or withdrawn entirely by a Rating
Agency if in its judgment circumstances (including without limitation a
reduction in the credit rating of the Interest Rate Swap Provider, the Currency
Swap Providers, the Mortgage Insurance Providers or a reduction in the domestic
currency rating of Australia) in the future so warrant. The ratings of the
Offered Notes will be based primarily on the creditworthiness of the Housing
Loans, the subordination provided by the Class B Notes with respect to the Class
A Notes, the availability of Excess Available Income, if any, the Mortgage Pool
Insurance Policy and the PMI Mortgage Insurance Policies, the availability of
the Liquidity Facility, the creditworthiness of the Interest Rate Swap Provider,
the Currency Swap Providers and the Mortgage Insurer Providers and the domestic
currency rating of Australia. In the context of an asset securitization, the
domestic currency rating of a country reflects, in general, a Rating Agency's
view of the likelihood that cash flow on the assets in such country's currency
will be permitted to be sent outside of that country.
    
 
BOOK-ENTRY NOTES
 
    Issuance of the Offered Notes in book-entry form may reduce the liquidity of
such Notes in the secondary trading market since investors may be unwilling to
purchase Offered Notes for which they cannot obtain physical certificates. Since
transactions in the Offered Notes can be effected only through DTC, Cedel,
Euroclear, participating organizations, indirect participants and certain banks,
the ability of a Noteholder to pledge an Offered Note to persons or entities
that do not participate in the DTC, Cedel or Euroclear systems or otherwise to
take actions in respect of such Notes, may be limited due to lack of a physical
certificate representing the Offered Notes. Noteholders may experience some
delay in their receipt of distributions of interest and principal on the Offered
Notes since such distributions will be forwarded by the Note Trustee to DTC and
DTC will credit such distributions to the accounts of its Participants (as
defined herein) which will thereafter credit them to the accounts of Noteholders
either directly or indirectly through indirect participants. See "DESCRIPTION OF
THE OFFERED NOTES-- Book-Entry Registration" herein.
 
OTHER CONSIDERATIONS
 
    There is no assurance that the market value of the Housing Loans will at any
time be equal to or greater than the Invested Amount of the Notes then
outstanding, plus accrued interest thereon. Moreover, upon an Event of Default
under the Security Trust Deed and a sale of the Trust Assets, the Security
Trustee, the Note Trustee, the Liquidity Facility Provider, the Swap Providers
and any other service provider generally will be entitled to receive the
proceeds of any such sale to the extent of unpaid fees and expenses and other
amounts owing to such persons prior to distributions to holders of the Notes.
After such payment of fees and expenses, the remaining proceeds thereof may be
insufficient to pay in full the principal of and interest on the Notes.
 
                             FORMATION OF THE TRUST
 
WESTPAC SECURITISATION TRUST PROGRAMME
 
    The Westpac Securitisation Trust Programme was established pursuant to the
Master Trust Deed for the purpose of enabling Westpac Securities Administration
Limited as trustee of each Trust established pursuant thereto, to invest in
pools of consumer assets originated from time to time by the Westpac Banking
Corporation group (the "Westpac Group"). The Master Trust Deed provides for the
creation of an unlimited number of WST trusts. Each WST trust will be a separate
and distinct trust fund and will be created subject to the Master Trust Deed and
a supplemental series notice establishing specific provisions of the relevant
WST trust and the instruments to be issued by that trust. The Trust Assets are
not available to meet the liabilities of any other WST trust formed under the
Master Trust Deed. Likewise, the assets of
 
                                       43
<PAGE>
any other trust formed under the Master Trust Deed are not available to meet the
liabilities of the Trust Series 1998-1G WST. Multiple classes of notes may be
issued by the Issuer Trustee in relation to each WST trust that differ among
themselves as to priority of payments and ratings.
 
SERIES 1998-1G WST TRUST
 
    The detailed terms of the Trust will be as set out in the Series Notice and
the Master Trust Deed. The Master Trust Deed establishes the general framework
under which WST trusts may be established from time to time. It does not
actually establish any trusts. To establish a trust, the Trust Manager and the
Issuer Trustee have executed a notice of creation of trust dated       (the
"Notice of Creation of Trust").
 
    In order to supplement the general framework under the Master Trust Deed
with respect to the Trust, all relevant parties (including the Trust Manager,
the Issuer Trustee and each Approved Seller) will execute the Series Notice,
which (among other things) specifies the details of the Notes, establishes the
cashflow allocation, sets out various representations and undertakings of the
parties specific to the Housing Loans, which are additional to those in the
Master Trust Deed, and amends the Master Trust Deed to the extent necessary to
give effect to the specific aspects of the Trust and the issue of the Notes.
 
   
    The Transaction Documents should therefore be read together when determining
the rights, powers and obligations of the Issuer Trustee, the Trust Manager and
the Approved Sellers in relation to the Trust. Forms of the Master Trust Deed
and the Series Notice have been filed as exhibits to the Registration Statement
of which this Prospectus is a part. The summaries herein do not purport to be
complete and are subject to the provisions of such documents.
    
 
    The issuance of the Notes will fund the purchase by the Trust of a pool of
residential housing loans originated by Westpac, which will be specified in a
Sale Notice from each of Westpac in its capacity as originator of the Housing
Loans or Westpac Securities Administration Limited in its capacity as trustee of
any other WST trusts established under the Master Trust Deed (in that capacity,
the "Seller Trustee"). The Seller Trustee owes a fiduciary duty to Westpac, the
entity which is the beneficiary of each "warehouse" trust established under the
Master Trust Deed.
 
    In addition, the Trust may issue certain additional debt securities as
discussed herein under "DESCRIPTION OF THE OFFERED NOTES--Description of the
Redraw Facility, the Redraw Funding Securities and the RFS Class A Notes."
 
TRUST ASSETS
 
    The Trust Assets will include:
 
        1.  a pool of Housing Loans, including all monies at any time paid or
    payable thereon or in respect thereof from and after the Cut-Off Date with
    respect to payments of principal and after the Closing Date with respect to
    payments of interest;
 
        2.  rights under certain insurance policies with respect to the Housing
    Loans;
 
        3.  amounts on deposit in certain accounts established pursuant to the
    Master Trust Deed, including the Collections Account, and amounts invested
    in Authorized Investments; and
 
        4.  the Issuer Trustee's rights under the Transaction Documents.
 
                             SECURITY FOR THE NOTES
 
CHARGE
 
   
    Under the Security Trust Deed, dated       , 1998 among the Issuer Trustee,
the Trust Manager, the Note Trustee and the Security Trustee, the Issuer Trustee
will grant a first ranking floating charge, to be registered with the Australian
Securities Commission, over all of the Trust Assets in favor of Perpetual
    
 
                                       44
<PAGE>
   
Trustee Company Limited (ACN 000 001 007) (the "Security Trustee"), a company
within the Perpetual group with its holding company being Perpetual Trustees
Australia Limited (ACN 000 431 827), in order to secure the Issuer Trustee's
obligations to the Noteholders, the Note Trustee, the Trust Manager, the
Interest Rate Swap Provider, the Currency Swap Providers, the Security Trustee,
each Paying Agent and each other provider of a Support Facility (other than any
provider of a Mortgage Insurance Policy) to the Issuer Trustee, any Accrued
Interest Adjustment (as defined herein) owed to an Approved Seller, to Westpac
in respect of Redraws and to the holders of the RFSs (if any) and the holders of
the RFS Class A Notes (if any) (such creditors, together the "Mortgagees").
    
 
SECURITY TRUSTEE
 
    The Security Trustee is appointed to act as trustee on behalf of the
Mortgagees on the terms and conditions of the Security Trust Deed. It holds the
benefit of the charge over the secured property (as defined herein) and the
benefit of each of the Transaction Documents to which the Issuer Trustee is a
party in trust for each Mortgagee in accordance with the terms and conditions of
the Security Trust Deed.
 
    If there is a conflict between the duties owed by the Security Trustee to
any Mortgagees or class of Mortgagees, the Security Trustee must give priority
to the interests of the holders of the RFSs (if any) and the RFS Class A Notes
(if any) and the Class A Noteholders and the Class B Noteholders (which in the
case of the Class A Noteholders and the Class B Noteholders shall be determined
by the Note Trustee acting on their behalf). Subject to the provisions of the
Security Trust Deed (other than the provision in the previous sentence), the
Security Trustee must give priority to the interests only of the Class A
Noteholders and the holders of the RFSs (if any) and the holders of the RFS
Class A Notes (if any) if, in the Security Trustee's opinion, there is a
conflict between the interests of Class A Noteholders and the holders of the
RFSs (if any) and the holders of the RFS Class A Notes (if any) and the
interests of the Class B Noteholders or other Mortgagees. Provided that the
Security Trustee acts in good faith, it shall not incur any liability to any
Mortgagee for giving effect or seeking to give effect to the preceding
provisions of this paragraph.
 
    The Security Trustee has had no involvement in the preparation of any part
of this Prospectus, other than the particular reference to the Security Trustee
in this section and the disclosure of additional provisions of the Security
Trust Deed set forth herein. The Security Trustee makes no statement or
representation in this Prospectus, has not authorized or caused the issue of any
part of it and takes no responsibility for any part of it.
 
NATURE OF SECURITY
 
    If a company grants a fixed security over any of its assets, those assets
may not be dealt with by the company without the consent of the relevant
mortgagee. In this way, the security is said to "fix" over the specific assets.
Fixed securities are usually given over real property, marketable securities and
other assets which will not be dealt with by the company.
 
    Unlike fixed securities, floating charges do not attach to specific assets
but instead "float" over a class of assets which may change from time to time,
allowing the person or entity granting the charge (the "Chargor") to deal with
those assets and to give third parties title to those assets free from any
encumbrance in the event of sale, discharge or modification, for example. The
security created by the Security Trust Deed is a floating charge over the Trust
Assets. The Security Trust Deed provides that the Issuer Trustee may not deal
with the assets of the Trust subject to the floating charge, except in the
ordinary course of its business. It is common in Australia for special purpose
securitization vehicles to give floating charges rather than fixed charges. If
the Issuer Trustee disposes of any of the Trust Assets (including any Housing
Loan) in the ordinary course of its business, the acquirer of that property will
take them free of the floating charge.
 
                                       45

    The floating charge created by the Security Trust Deed may "crystallize" and
become a fixed charge over the relevant class of assets owned by the Issuer
Trustee at the time of crystallization. Crystallization will occur automatically
following the occurrence of specific events set out in the Security Trust Deed,
including, among other events, notice to the Issuer Trustee from the Security
Trustee following an event of default. See "CERTAIN LEGAL ASPECTS OF THE HOUSING
LOANS" and "APPENDIX I-- GLOSSARY OF AUSTRALIAN LEGAL TERMS" herein.
 
ENFORCEMENT
 
   
    [The Security Trustee must promptly convene a meeting of the Voting
Mortgagees (as defined herein) after it receives notice, or has actual knowledge
of, an Event of Default (as defined herein). See "DESCRIPTION OF THE OFFERED
NOTES--Events of Default; Rights Upon Event of Default." The Security Trustee
may waive (such waiver, being subject to the prior written consent of the Note
Trustee in accordance with the provisions of the Security Trust Deed), an Event
of Default before it is required to convene a meeting of Mortgagees if that
Event of Default is not (in the opinion of the Security Trustee) materially
prejudicial to the Mortgagees' interests.]
    
 
   
    [At the meeting, the Voting Mortgagees must vote by Extraordinary Resolution
(being a resolution passed at a duly convened meeting by a majority consisting
of not less than 75% of the votes capable of being cast by Voting Mortgagees
present in person or by proxy or by written resolution signed by all of the
Voting Mortgagees)] on whether to direct the Security Trustee to:
    
 
        (1) declare the charge to be enforceable;
 
   
        (2) declare the Secured Moneys immediately due and payable;
    
 
        (3) crystallize the floating charge created under the Security Trust
    Deed in relation to any or all of the Secured Property (for a description of
    the crystallization process, see "--Nature of Security" above); and/or
 
        (4) appoint a receiver over the Trust's assets or itself exercise the
    powers that a receiver would otherwise have under the Security Trust Deed.
 
   
    "Secured Moneys" means all money which the Issuer Trustee (whether alone or
with another person) is or at any time may become actually or contingently
liable to pay to or for the account of any Mortgagee (whether alone or with
another person) for any reason whatever under or in connection with a
Transaction Document.
    
 
   
    [With respect to voting, every person who is present at a meeting shall have
one vote in respect of each US$ in principal amount of the Stated Amount of the
Offered Notes then outstanding of the Class A Notes or the Class B Notes, as the
case may be, so produced or represented by the voting certificate so produced or
in respect of which he is a proxy.]
    
 
   
    The Security Trustee cannot exercise the powers referred to above unless
directed by an Extraordinary Resolution in the manner outlined above. The
Security Trustee is not obligated to act unless it obtains an indemnity from the
Voting Mortgagees, and funds have been deposited on behalf of the Security
Trustee to the extent to which it may become liable for the relevant enforcement
actions. For so long as the Note Trustee is the only Voting Mortgagee it may
direct the Security Trustee to do any act which the Security Trustee is required
to do, or may only do, at the direction of an Extraordinary Resolution of Voting
Mortgagees. [Neither the Security Trustee nor the Trust Manager may call a
meeting of Voting Mortgagees while the Note Trustee is the only Voting
Mortgagee, unless the Note Trustee otherwise consents.]
    
 
    The Note Trustee will be the only Voting Mortgagee for so long as the
amounts outstanding under the Notes are 75% or more of all amounts secured by
the Security Trust Deed.
 
                                       46
<PAGE>
   
    For the purposes of the Security Trust Deed and the Note Trust Deed, a
reference to Class A Noteholders include RFS Class A Noteholders, if any.
    
 
    No Mortgagee is entitled to enforce the charge under the Security Trust
Deed, or appoint a receiver or otherwise exercise any power conferred by any
applicable law on charges, other than in accordance with the Security Trust
Deed.
 
PRIORITIES UNDER THE SECURITY TRUST DEED
 
    The proceeds from the enforcement of the Security Trust Deed (which will not
include amounts required by law to be paid to the holder of any prior ranking
security interest, the proceeds of or amounts credited to the collateral account
under the Liquidity Facility and payable to the Liquidity Facility Provider and
the proceeds of cash collateral lodged with and payable to a provider of a Swap
Agreement or provider of another Support Facility to the Issuer Trustee) are to
be applied in the order of priority set forth below, subject to any other
priority which may be required by statute or law. Priority of proceeds in
enforcement over secured creditors includes certain federal taxes, unpaid wages,
long service leave, annual leave and similar employee benefits and certain
auditor's fees.
 
        (1) first, to pay all costs, charges, expenses and disbursements
    properly incurred in the exercise of any power by the Security Trustee, the
    Note Trustee, a receiver or an attorney or other amounts (other than those
    referred to in paragraph (4) below) payable to the Security Trustee or the
    Note Trustee under the Security Trust Deed;
 
        (2) second, to pay pro rata based on their respective entitlements:
 
        (i) any fees and other expenses (including Trust Expenses) due to the
    Security Trustee, the Note Trustee or the Principal Paying Agent;
 
        (ii) any fees and unpaid expenses, due to the Issuer Trustee; and
 
       (iii) the receiver's remuneration;
 
        (3) third, to pay pro rata any unpaid Accrued Interest Adjustment due to
    an Approved Seller;
 
        (4) fourth, to pay pro rata based on their respective entitlements:
 
   
        (i) all Secured Moneys (as defined herein) owing to the providers of
    each Support Facility (other than the Currency Swap Providers);
    
 
        (ii) all Secured Moneys owing to the holders of RFSs (if any);
 
       (iii) all Secured Moneys owing to the holders of RFS Class A Notes (if
    any);
 
        (iv) all the Secured Moneys owing to the Class A Noteholders (as at the
    date of payment);
 
        (v) all Secured Moneys owed by the Issuer Trustee as trustee of the
    Trust to a WST trust other than the Trust;
 
   
        (vi) all Secured Moneys owing in relation to any Redraws made by Westpac
    for which it has not been reimbursed under the Transaction Documents; and
    
 
   
       (vii) all Secured Moneys owing to the Currency Swap Providers under a
    confirmation relating to Class A Notes (but without double counting with
    payments under sub-paragraph (iv));
    
 
   
        (5) fifth, all Secured Moneys owing to the Class B Noteholders (as at
    the date of payment) and to the Currency Swap Providers under a confirmation
    relating to the Class B Notes, but without double counting;
    
 
        (6) sixth, to pay (PARI PASSU and rateably) any amounts not covered
    above owing to any Mortgagee under any Transaction Document;
 
                                       47
<PAGE>
        (7) seventh, to pay the holder of any subsequent security interest over
    the assets charged by the Security Trust Deed of which the Security Trustee
    has notice of the amount properly secured by the security interest;
 
        (8) eighth, to pay any surplus to the Issuer Trustee to be distributed
    in accordance with the Master Trust Deed.
 
    The surplus will not carry interest. If the Security Trustee pays the
surplus to the credit of an account in the name of the Issuer Trustee with any
bank carrying on business in Australia, the Security Trustee, receiver,
Mortgagee or attorney (as the case may be) will be under no further liability in
respect of it.
 
    The "Accrued Interest Adjustment" represents interest and fees which have
accrued on the relevant Housing Loans but which are unpaid as at (and excluding)
the Closing Date, and all amounts received by the relevant Approved Seller under
those Housing Loans applied by the Servicer to payment of interest and fees
under those Housing Loans for the period from (but excluding) the Cut-Off Date
to (but excluding) the Closing Date. During the period between the Cut-Off Date
and the Closing Date, the Housing Loans continue to be owned by the Approved
Sellers. However, any Collections with respect to the period from the Cut-Off
Date through the Closing Date will not be paid back to Westpac until after the
assignment of the Housing Loans to the Trust. The purchase price for the Housing
Loans excludes any such accrual. Therefore, an amount equal to that accrued
interest and fees and Collections in respect of interest and fees for the period
between the Cut-Off Date and the Closing Date will be paid to the Approved
Sellers on the first Payment Date as a priority payment from Total Available
Funds.
 
   
SECURITY TRUSTEE'S FEES AND EXPENSES
    
 
   
    The Issuer Trustee shall reimburse the Security Trustee for all costs and
expenses of the Security Trustee properly incurred in acting as Security
Trustee. The Security Trustee shall be entitled to a fee payable quarterly (the
"Security Trustee Fee") in the amount agreed from time to time by the Issuer
Trustee, the Security Trustee and the Trust Manager. The Issuer Trustee has
agreed to indemnify the Security Trustee against any loss, cost, charge,
liability, expense or damage under or in relation to the Transaction Documents,
except where arising from the Security Trustee's fraud, negligence or willful
default.
    
 
RETIREMENT AND REMOVAL
 
   
    Subject to the appointment of a successor Security Trustee, the Security
Trustee may retire on three months' notice in writing to the Issuer Trustee, the
Trust Manager, the Note Trustee and the Rating Agencies. The Security Trustee
may resign in favor of a successor Security Trustee only if the Rating Agencies
confirm that such resignation will not cause a withdrawal, downgrade or
qualification of the ratings of the Offered Notes.
    
 
   
    Subject to the appointment of a successor Security Trustee and prior notice
being given to each of the Rating Agencies, an Extraordinary Resolution of the
Voting Mortgagees may at any time remove the Security Trustee.
    
 
    Subject to the appointment of a successor Security Trustee and prior notice
being given to each of the Rating Agencies, the Trust Manager may remove the
Security Trustee if any of the following occurs in relation to the Security
Trustee: (i) an Insolvency Event occurs in relation to the Security Trustee in
its personal capacity; (ii) the cessation by the Security Trustee of its
business; (iii) the failure by the Security Trustee to remedy within 14 days
after written notice by the Trust Manager any material breach of duty on the
part of the Security Trustee; or (iv) if without the prior written consent of
the Trust Manager there occur certain changes in the control or management of
the Security Trustee.
 
                                       48
<PAGE>
   
    Upon notice of resignation or removal of the Security Trustee, the Trust
Manager has the right to appoint a successor Security Trustee who has been
previously approved by an Extraordinary Resolution of the Voting Mortgagees and
who accepts the appointment. If no successor Security Trustee is appointed
within 30 days after notice, the retiring Security Trustee may on behalf of the
Mortgagees appoint a successor Security Trustee (other than Westpac or a related
corporation of Westpac) who accepts the appointment. There are currently several
third party security trustee organizations in Australia which may be available
to replace a resigning or removed security trustee.
    
 
ADDITIONAL PROVISIONS OF THE SECURITY TRUST DEED
 
   
    The Security Trust Deed may be amended by the Issuer Trustee and the
Security Trustee with the written approval of the Trust Manager and the Note
Trustee in the manner (and subject to the restrictions) set out in the Security
Trust Deed.
    
 
    The Security Trust Deed contains a range of provisions regulating the scope
of the Security Trustee's duties and liability. These include the following:
 
        (1) The Security Trustee is not responsible for the adequacy or
    enforceability of the Security Trust Deed or other Transaction Documents.
 
        (2) The Security Trustee is not required to exercise its powers under
    the Security Trust Deed without being directed to do so by the Note Trustee
    or by an Extraordinary Resolution (as referred to above) of the Voting
    Mortgagees.
 
   
        (3) The Security Trustee may rely on documents provided by the Issuer
    Trustee or Trust Manager and the advice of consultants and advisors.
    
 
        (4) The Security Trustee is not required to monitor whether an event of
    default has occurred or compliance by the Issuer Trustee or Trust Manager
    with the Transaction Documents, or their other activities.
 
        (5) The Security Trustee is not required to do anything unless its
    liability is limited in a manner satisfactory to it.
 
        (6) The Security Trustee need not give Mortgagees information concerning
    the Issuer Trustee which comes into the possession of the Security Trustee.
 
   
        (7) The rights, remedies and discretion of the Noteholders including all
    rights to vote or give instructions or consents to the Security Trustee and
    to enforce its undertakings and warranties may only be exercised by the Note
    Trustee on behalf of the Class A and Class B Noteholders and the Security
    Trustee may rely on any instructions or directions given to it by Note
    Trustee as being given on behalf of the Noteholders without enquiry about
    compliance with the Note Trust Deed.
    
 
        (8) The Security Trustee has no duties or responsibilities except those
    expressly set out in the Security Trust Deed or any collateral security.
 
        (9) Any action taken by the Security Trustee under the Security Trust
    Deed or any collateral security binds all the Mortgagees.
 
   
        (10) Each Mortgagee must make its own independent investigations,
    without reliance on the Security Trustee, as to the affairs of the Issuer
    Trustee and whether or not to take action under any Transaction Document.
    
 
        (11) The Security Trustee in its capacity as a Mortgagee can exercise
    its rights and powers as such as if it were not acting as the Security
    Trustee. It and its affiliates may engage in any kind of business with the
    Issuer Trustee, the Trust Manager, Mortgagees and others as if it were not
    Security Trustee and may receive consideration for services in connection
    with any Transaction Document or otherwise without having to account to the
    Mortgagees.

                                 THE TRUST FUND
 
GENERAL
 
    The Housing Loans are expected to include       Housing Loans secured by
registered first ranking mortgages (collectively, the "Mortgages") on Mortgaged
Properties located in Australia. This subsection describes generally the
characteristics of the Housing Loans. The Mortgaged Properties consist of owner-
occupied properties and investment properties. The Mortgaged Properties do not
include mobile homes which are not permanently affixed to the ground, commercial
properties or unimproved land. With respect to each Housing Loan, the "Cut-Off
Date Balance Outstanding" is the unpaid principal balance of such Housing Loan
as of the close of business on the Cut-Off Date. Housing Loans included in the
Trust Fund consist of floating and fixed rate loans originated by Westpac.
 
TRANSFER AND ASSIGNMENT OF HOUSING LOANS
 
    On the Closing Date, the Housing Loans purchased by the Trust will be those
specified in a Sale Notice from each of the Approved Sellers to the Issuer
Trustee. The Housing Loans to be sold by either the Seller Trust or by Westpac
from Westpac's general portfolio of residential Housing Loans have been in both
cases originated by Westpac in the ordinary course of its business. Each Housing
Loan may have some or all of the product features set out in "WESTPAC
RESIDENTIAL LOAN PROGRAM--Housing Loan Features" below. The Housing Loans are,
generally, required to be secured by a registered first ranking real property
mortgage and, in certain circumstances, there may also be a second ranking
mortgage in favor of Westpac. For more information on the Housing Loans, see
"WESTPAC RESIDENTIAL LOAN PROGRAM" below.
 
    On the Closing Date, the Approved Sellers will equitably assign the Housing
Loans, the Mortgages and the Related Securities (as defined herein) securing
those Housing Loans to the Issuer Trustee, pursuant to the Sale Notices
substantially in the form annexed to the Master Trust Deed, after which the
Issuer Trustee will be entitled to receive (with the assistance of TMC in its
capacity as servicer (the "Servicer") of the Housing Loans and custodian of
Related Documents (as defined herein), including the mortgage documents relating
to the Housing Loans) Collections on the Housing Loans. If a Title Perfection
Event occurs, the Issuer Trustee must, with the assistance of the Trust Manager
and Westpac, take certain actions to perfect its legal title in the Housing
Loans pursuant to an irrevocable power of attorney granted by Westpac.
 
    "Related Security" in relation to a Housing Loan means: (a) any Relevant
Document for that Housing Loan; (b) any insurance policy or insurance proceeds
with respect to the Housing Loan; (c) any Mortgage Insurance Policy or Mortgage
Insurance Proceeds with respect to the Housing Loan; or (d) any other agreement
specified as "Related Security" for the Housing Loan in the Series Notice.
"Relevant Document" means, with respect to a Housing Loan, (a) the loan
agreement relating to that Housing Loan; (b) the mortgage document in relation
to such Housing Loan, (c) the certificate of title for the Mortgaged Property
secured by such mortgage, (d) any amendment or replacement of such documents and
any other document which is entered into by or executed in favor of the Approved
Seller or Issuer Trustee in connection with that Housing Loan after the Cut-Off
Date, or (e) any other document specified as a "Relevant Document" in the Series
Notice.
 
    An Approved Seller may in some instances assign to the Issuer Trustee a
Housing Loan secured by an "all moneys" Mortgage, which may also secure
financial indebtedness that has not been sold into the Mortgage Pool and is
instead retained by Westpac. The Issuer Trustee will hold the benefit of the
relevant Mortgage as bare trustee in relation to that other financial
indebtedness, although the Mortgage will secure the assigned Housing Loan in
priority to that other financial indebtedness.
 
                                       50

REPRESENTATIONS AND WARRANTIES
 
    Westpac will make certain representations and warranties to the Issuer
Trustee in relation to the Housing Loans to be assigned by it to the Issuer
Trustee. Westpac also made representations and warranties in relation to the
Housing Loans to be sold by the Seller Trustee at the time those Housing Loans
were first transferred by Westpac to each relevant Seller Trustee, and the
benefit of those prior representations and warranties will be passed on to the
Issuer Trustee. The Servicer will make certain representations and warranties to
the Issuer Trustee in relation to the servicing of the Housing Loans to be sold
by the Seller Trustee to the Issuer Trustee. These representations and
warranties cover the period from when those Housing Loans were first transferred
by Westpac to other Seller Trusts until the Cut-Off Date. The Seller Trustee
will make certain limited representations and warranties in relation to the
Housing Loans to be assigned by it (e.g., as to title) to the Issuer Trustee.

    That servicing includes, without limitation, ensuring compliance with the
    Consumer Credit Legislation in connection with servicing the Housing Loans
    where failure to do so would have an Adverse Effect.
 
SELLER TRUSTEE REPRESENTATIONS
 
    In relation to the Housing Loans to be sold by the Seller Trustee to the
Issuer Trustee, the Seller Trustee will make representations and warranties for

    trust. That Security Trust Deed created only a floating charge over the
    Housing Loans; and
 
        (2) the sale, transfer and assignment of the Seller Trustee's interest
    in the Housing Loans will not constitute a breach of any documents binding
    on the Seller Trustee.
 
GENERAL
 
    The Issuer Trustee has not investigated or made any inquiries regarding the
accuracy of the representations and warranties, and under the Master Trust Deed
is under no obligation to do so. The Issuer Trustee is entitled to rely entirely
upon the representations and warranties being correct (unless it has actual
notice of any event to the contrary). The rights of the Issuer Trustee in
respect of any representation or warranty being incorrect are described in
"--Breach of Representations" below.
 
BREACH OF REPRESENTATIONS AND WARRANTIES
 
    If Westpac, the Trust Manager or the Issuer Trustee becomes aware within 120
days after the Closing Date that a representation or warranty from Westpac
relating to any Housing Loan or Mortgage is incorrect, it must notify the other
parties and the Rating Agencies within five Business Days of becoming so aware.
If such a notice in relation to a breach is given not later than five Business
Days before 120 days after the Closing Date and the breach is not waived or
remedied to the satisfaction of the Issuer Trustee within five Business Days
then, without any action being required by either party, Westpac shall be
 
                                       52
<PAGE>
obligated to repurchase the affected Housing Loan and Mortgage for an amount
equal to its Unpaid Balance.
 
    On payment of that amount the Issuer Trustee shall cease to have any
interest in the affected Housing Loan and Mortgage, and Westpac shall hold both
the legal and beneficial interest in such Housing Loan and Mortgage and be
entitled to all interest and fees that accrue in respect of them from (and
including) the date of repurchase.
 
    In any other case, the Issuer Trustee's rights in relation to a breach of a
representation or warranty shall give rise only to a claim for damages, limited
to an amount equal to the Unpaid Balance of that Housing Loan at the time
Westpac pays the damages.
 
HOUSING LOAN STATISTICS
 
    The Housing Loans will consist of       Housing Loans secured by Mortgages
on Mortgaged Properties located in the six states and two territories in
Australia, being New South Wales ("NSW"), Victoria ("Vic"), Queenslands ("QLD"),
South Australia ("SA"), Western Australia ("WA"), Tasmania ("TAS"), Northern
Territory ("NT") and the Australian Capital Territory ("ACT"). 100% of the
Housing Loans by Cut-Off Date Balances Outstanding are secured by first ranking
mortgages on the related Mortgaged Properties. The aggregate Cut-Off Date
Balances Outstanding of the Housing Loans (the "Cut-Off Date Pool Balance")
totaled approximately A$      . The Housing Loans bear interest at variable and
fixed rates. As of the Cut-Off Date,    % of the Housing Loans by Cut-Off Date
Loan Balance are variable rate loans (the "Variable Rate Housing Loans") and
   % of the Housing Loans by Cut-Off Date Loan Balance are fixed rate loans (the
"Fixed Rate Housing Loans"). The weighted average Mortgage Rate for the Fixed
Rate Housing Loans as of the Cut-Off Date was approximately    % per annum. The
weighted average Mortgage Rate for the Variable Rate Housing Loans as of the
Cut-Off Date was approximately    % per annum. The lowest Cut-Off Date Balance
Outstanding of any Housing Loan was approximately A$      and the highest was
approximately A$      . The average Cut-Off Date Balance Outstanding of the
Housing Loans was approximately A$      . The weighted average original term to
stated maturity of the Housing Loans was approximately       months. The
weighted average remaining term to stated maturity of the Housing Loans was
approximately       months. As of the Cut-Off Date, the weighted average number
of months that have elapsed since origination of the Housing Loans was
approximately       months. The lowest and highest LVR of the Housing Loans at
origination were approximately    % and    %, respectively. The weighted average
LVR of the Housing Loans was approximately    %.
 
    Housing Loans representing approximately    % of the Cut-Off Date Pool
Balance are secured by Mortgaged Properties which are investment properties

POWERS
 
    Subject to the Master Trust Deed and the Series Notice, the Issuer Trustee
has all the rights, powers and discretion over and in respect of the Trust
Assets which it could exercise as if it were the beneficial owner of those
assets. These powers include the ability to invest in Authorized Investments, to
issue Notes and to enter into Support Facilities.
 
    The Master Trust Deed expressly permits the Issuer Trustee to appoint the
Servicer to retain custody of the mortgage documents for the Trust in accordance
with the Servicing Agreement, and for the Issuer Trustee to lodge documents with
the Servicer.
 
    Full details of the powers of the Issuer Trustee are set out in the Master
Trust Deed.
 
DUTIES
 
    The Issuer Trustee is required to act honestly and in good faith and to
exercise such diligence and prudence as a prudent person of business would
exercise in performing its express functions and in exercising its discretion
under the Master Trust Deed. It must keep each WST trust separate from the
others and do everything necessary to ensure it can comply with its obligations
under the Transaction Documents.
 
                                       60
<PAGE>
   
    In particular the Issuer Trustee has the duty to maintain a register of
Authorized Investments (other than the Housing Loans) and to ensure that the
Trust Manager keeps accounting records which correctly record and explain all
amounts paid and received by the Issuer Trustee.
    
 
    The Issuer Trustee is required to act continuously as trustee of the Trust
until the Trust is terminated as provided by the Master Trust Deed or the Issuer
Trustee has retired or been removed from office in the manner detailed below.
 
    Each Noteholder acknowledges that:
 
        (1) In the absence of fraud, negligence or breach of trust on its part,
    the Issuer Trustee shall not be liable personally in the event of failure to
    make payments on the Payment Date for payment to any Noteholder, any
    Beneficiary, the Trust Manager or any other person or for any loss howsoever
    caused in respect of any of the trusts or to any Noteholder, any
    Beneficiary, the Trust Manager or any other person.
 
        (2) The Issuer Trustee acts as trustee only in its capacity as trustee
    of the Trust and in no other capacity. Any liability arising under or in
    connection with a Transaction Document (including, without limitation, the
    Offered Notes) can be enforced against the Issuer Trustee only to the extent
    to which it can be satisfied out of property of the Trust out of which the
    Issuer Trustee is actually indemnified for the liability. This limitation of
    the Issuer Trustee's liability applies despite any other provision of the
    Transaction Documents and extends to all liabilities and obligations of the
    Issuer Trustee in any way connected with any representation, warranty,
    conduct, omission, agreement or transaction related to the Transaction
    Documents or the Trust. The limitation will not apply if there is a
    reduction in the Issuer Trustee's indemnification out of trust assets as a
    result of the Issuer Trustee's fraud, negligence or breach of trust.
 
   
        (3) The Issuer Trustee has no duty, and is under no obligation, to
    investigate whether a Trust Manager's Default, Servicer Transfer Event or
    Title Perfection Event has occurred in relation to the Trust other than
    where it has actual notice;
    
 
   
        (4) The Issuer Trustee is required to provide the notices referred to in
    the Master Trust Deed in respect of a determination of Adverse Effect only
    if it is actually aware of the facts giving rise to the Adverse Effect; and
    
 
   
        (5) In making any such determination, the Issuer Trustee will seek and
    rely on advice given to it by its advisers in a manner contemplated by the
    Master Trust Deed.
    
 
    The Issuer Trustee is entitled to rely conclusively on, and is not required
to investigate the accuracy of:
 
        (i) the contents of a Sale Notice given to it by an Approved Seller;
 
        (ii) the contents of any report given to it by the Trust Manager or the
    Servicer;
 
       (iii) any calculations made by an Approved Seller, a Servicer or the
    Trust Manager including the calculation of payments due to, or to be charged
    against, the Noteholders;
 
        (iv) the amount of, or allocation of, Collections; or
 
        (v) the contents of any certificate provided to the Issuer Trustee under
    the Master Trust Deed or any certificate given by the Trust Manager or the
    Servicer, unless the Issuer Trustee is actually aware to the contrary. The
    Issuer Trustee is not liable to any person in any manner whatsoever in
    respect of these matters.
 
    The Master Trust Deed also contains other provisions which regulate the
Issuer Trustee's liability to Noteholders, other creditors and any Beneficiary.
The Issuer Trustee is not liable to any person for any losses, costs,
liabilities or expenses arising out of the exercise or non exercise of its
discretion (or by the Trust Manager of its discretion) or for any instructions
or directions given to it by the Trust Manager, the
 
                                       61
<PAGE>
Servicer or either of the Approved Sellers. The Issuer Trustee is also not
liable for any Trust Manager's Default, Servicer Transfer Event or Title
Perfection Event. The Issuer Trustee is not liable for any act, omission or
default of the Servicer in relation to its custodian duties or its obligations
under the Servicing Agreement.
 
DELEGATION
 
    In exercising its powers and performing its obligations and duties under the
Master Trust Deed, the Issuer Trustee may, with the approval of the Trust
Manager, delegate any or all of the duties, powers, discretion or other
functions of the Issuer Trustee under the Master Trust Deed or otherwise in
relation to the Trust, to a related company of the Issuer Trustee which is a
trustee company or trustee corporation for the purposes of any State or
Territory legislation governing the operation of trustee companies.
 
ISSUER TRUSTEE FEES AND EXPENSES
 
    The Issuer Trustee is entitled to a quarterly fee (the "Issuer Trustee Fee")
based on the average daily balance of the aggregate Housing Loan principal
during each Collection Period, payable in arrears on the relevant Payment Date.
 
    The Issuer Trustee is entitled to be reimbursed out of the assets of the
Trust for all expenses incurred in connection with the performance of its
obligations in respect of the Trust (other than general overhead costs and
expenses).
 
REMOVAL OF THE ISSUER TRUSTEE
 
    The Issuer Trustee is required to retire as trustee after a direction from
the Trust Manager following an "Issuer Trustee's Default." An Issuer Trustee's
Default occurs if:
 
        (1) an Insolvency Event has occurred and is continuing in relation to
    the Issuer Trustee;
 
        (2) any action is taken by or in relation to the Issuer Trustee which
    causes the rating of any Notes to be downgraded;
 
        (3) the Issuer Trustee, or any employee, delegate, agent or officer of
    the Issuer Trustee, breaches any obligation or duty imposed on the Issuer
    Trustee under the Master Trust Deed or any other Transaction Document in
    relation to the Trust where the Trust Manager reasonably believes it may
    have an Adverse Effect and the Issuer Trustee fails or neglects after 30
    days' notice from the Trust Manager to remedy that breach;
 
        (4) the Issuer Trustee merges or consolidates with another entity
    without obtaining the consent of the Trust Manager and ensuring that the
    resulting merged or consolidated entity assumes the Issuer Trustee's
    obligations under the Transaction Documents; or
 
        (5) there is a change in effective control of the Issuer Trustee from
    that subsisting as at the date of the Master Trust Deed unless approved by
    the Trust Manager.
 
    Where the Issuer Trustee is removed because of its default, it shall bear
the costs of its removal. The Issuer Trustee indemnifies the Trust Manager and
the Trust for those costs.
 
    On the removal of the Issuer Trustee, the Trust Manager, subject to giving
prior notice to the Rating Agencies, shall be entitled to appoint in writing
some other statutory trustee to be the Issuer Trustee under the Master Trust
Deed provided that appointment will not in the reasonable opinion of the Trust
Manager materially prejudice the interests of Noteholders. Until the appointment
is completed the Trust Manager shall act as Issuer Trustee and will be entitled
to the trustee's fee for the period it so acts as Issuer Trustee.
 
                                       62
<PAGE>
VOLUNTARY RETIREMENT OF THE ISSUER TRUSTEE
 
    The Issuer Trustee may resign on giving to the Trust Manager (with a copy to
the Rating Agencies) not less than 3 months' notice in writing (or such other
period as the Trust Manager and the Issuer Trustee may agree) of its intention
to do so.
 
    Before retirement, the Issuer Trustee must appoint a successor trustee who
is approved by the Trust Manager, or who may be the Trust Manager, and whose
appointment will not materially prejudice the interests of Noteholders. If a
successor trustee has not been appointed by the end of the 3 months' notice
period the Trust Manager shall act as trustee until a successor trustee is
appointed.
 
LIMITATION OF ISSUER TRUSTEE'S LIABILITY
 
    In the absence of fraud, negligence or breach of trust on its part, the
Issuer Trustee shall not be liable personally in the event of failure to pay
moneys on the Payment Date for payment to any Noteholder, any Beneficiary, the
Trust Manager or any other person or for any loss howsoever caused in respect of
any of the trusts or to any Noteholder, any Beneficiary, the Trust Manager or
any other person.
 
   
    The Issuer Trustee acts as trustee only in its capacity as trustee of the
Trust and in no other capacity. A Noteholder cannot sue the Issuer Trustee
personally except in the case of fraud, negligence or breach of trust on the
part of the Issuer Trustee. Any liability arising under or in connection with a
Transaction Document (including, without limitation, any Offered Note) can be
enforced against the Issuer Trustee only to the extent to which it can be
satisfied out of property of the Trust out of which the Issuer Trustee is
actually indemnified for the liability. This limitation of the Issuer Trustee's
liability applies despite any other provision of the Transaction Documents and
extends to all liabilities and obligations of the Issuer Trustee in any way
connected with any representation, warranty, conduct, omission, agreement or
transaction related to the Transaction Documents or the Trust. The limitation
will not apply to the extent that there is a reduction in the Issuer Trustee's
indemnification out of trust assets as a result of the Issuer Trustee's fraud,
negligence or breach of trust.
    
 
    The Issuer Trustee is also indemnified out of the Trust assets against
certain payments which it may be liable to make under the Consumer Credit
Legislation. Westpac has also indemnified the Issuer Trustee in relation to such
payments and the Issuer Trustee is required to first call on the indemnity from
Westpac.
 
RIGHTS OF INDEMNITY OF ISSUER TRUSTEE
 
   
    Except where the Issuer Trustee fails to exercise due care or is otherwise
disentitled (including, without limitation, because of fraud, negligence or
breach of trust on its part) the Issuer Trustee will be indemnified out of the
Trust Assets against all losses and liabilities incurred by the Issuer Trustee
in properly performing any of its duties or exercising any of its powers under
the Transaction Documents in relation to the Trust.
    
 
LIMITATION OF SELLER TRUSTEE'S LIABILITY AND RIGHTS OF INDEMNITY
 
    In the absence of fraud, negligence or breach of trust on its part, the
Seller Trustee shall not be liable personally in the event of failure to pay
moneys on the Payment Date for payment to any Noteholder, any Beneficiary, the
Trust Manager or any other person or for any loss howsoever caused in respect of
any of the trusts or to any Noteholder, any Beneficiary, the Trust Manager or
any other person.
 
    The Seller Trustee acts as Seller Trustee only in its capacity as seller
trustee of the relevant Seller Trust and in no other capacity. A liability
arising under or in connection with a Transaction Document can be enforced
against the Seller Trustee only to the extent to which it can be satisfied out
of property of the relevant Seller Trust out of which the Seller Trustee is
actually indemnified for the liability. This limitation of the Seller Trustee's
liability applies despite any other provision of the Transaction Documents and
extends to all liabilities and obligations of the Seller Trustee in any way
connected with any representation,
 
                                       63
<PAGE>
   
warranty, conduct, omission, agreement or transaction related to the Transaction
Documents, the Trust or the relevant Seller Trust. The limitation will not apply
to the extent that there is a reduction in the Seller Trustee's indemnification
out of trust assets or the relevant Seller Trust as a result of the Seller
Trustee's fraud, negligence or breach of trust.
    
 
    The Seller Trustee is also indemnified out of the assets of the relevant
Seller Trust against certain payments which it may be liable to make under the
Consumer Credit Legislation. Westpac has also indemnified the Seller Trustee in
relation to such payments and the Seller Trustee is required to first call on
the indemnity from Westpac.
 
RIGHTS OF INDEMNITY OF SELLER TRUSTEE
 
    Except where the Seller Trustee fails to exercise due care or is otherwise
disentitled (including, without limitation, because of fraud, negligence or

                        ORIGINATOR OF THE HOUSING LOANS
 
   
    Westpac Banking Corporation ("Westpac"), Level 4, 60 Martin Place, Sydney,
NSW 2000, Australia, was established from an amalgamation of the Bank of New
South Wales and the Commercial Bank of Australia Limited (the "CBA") in 1982.
The Bank of New South Wales was Australia's first bank and was established in
1817 to promote the commercial growth of the colony and thus helped to lay the
foundations of Australia's banking system. The CBA was established in Melbourne,
Victoria in 1866 in response to the needs of the expanding business community,
principally brought about by the Victorian gold rush of the period.
    
 
    Today Westpac is one of the four major commercial banks in Australia and is
the largest commercial bank in New Zealand. The Westpac Group undertakes a wide
range of banking and financial activities including commercial and investment
banking, personal and small business banking, retail and wholesale funds
management, financial services and finance company operations.
 
    The banking activities of Westpac come under the supervision of the Reserve
Bank of Australia.
 
YEAR 2000
 
    The origin of the Year 2000 "millennium bug" problem lies in the way
information in computer systems relating to calendar dates has been stored.
Computer systems, built when data storage was expensive, saved only the last two
digits of a year for date calculations in order to reduce data storage
requirements. These systems are therefore unable to differentiate, for example,
between the years 1900 and 2000. This inability to differentiate between the
different centuries could result in discrepancies such as erroneous interest
rate calculations and inaccurate statement reporting.
 
   
    In recognition of the seriousness of the problem, work within the Westpac
Group began in 1996 when a Year 2000 project was initiated. The conversion plan
for making the Westpac Group's applications Year 2000 compliant is estimated to
cost A$60 million, of which A$24 million has been spent as of the end of March
1998. To the maximum extent possible, the project will utilize existing Westpac
Group resources. The objective is that all of the Westpac Group will be Year
2000 compliant by December 31, 1998, to allow adequate time for testing and to
minimize resource requirements in later years. Management of Westpac currently
estimates that the balance of the Year 2000 project conversion will be completed
by December 1998.

                                  THE SERVICER
 
GENERAL
 
    In 1996, Westpac established a wholly owned subsidiary, TMC of Level 6, 228
Pitt Street, Sydney 2000, Australia, to provide mortgage servicing capability to
both Westpac and to third parties. TMC operates from a new purpose built
servicing center in Adelaide, known as the Mortgage Processing Centre ("MPC").
The MPC employs over 1,000 staff, and processes approximately 1400 new
applications per day.
 
    The MPC performs the following functions for Westpac: application
processing, telephone support, pre-settlement, settlement, post-settlement,
servicing and account maintenance, collections and enforcement and document
custody.
 
SERVICING OF HOUSING LOANS
 
    Under the Servicing Agreement, the ongoing servicing of the Housing Loans
will be performed by TMC, as the Servicer at the MPC. Servicing procedures
include responding to customer inquiries, managing and servicing the features
and facilities available under the Housing Loans and the management of
delinquent Housing Loans. The servicing functions performed by the MPC support,
and are supported by, the activities of Westpac's branches, telemarketing and
telebanking centers. In addition, the MPC services housing loans for third
parties.
 
    The Servicer is contractually obligated to administer the Housing Loans in
accordance with (i) the Servicing Agreement; (ii) Westpac's policies, which are
under regular review and may change from time to time in accordance with
business judgment and changes to legislation and guidelines established by
relevant regulatory bodies; and (iii) to the extent not covered by paragraphs
(i) and (ii), by exercising the degree of diligence and care expected of an
appropriately qualified Servicer of the relevant Housing Loans. See "DESCRIPTION
OF THE SERVICING AGREEMENT."
 
DOCUMENT CUSTODY
 
    The Servicer is responsible for custody of the mortgage title documents on
behalf of the Issuer Trustee and has custody of the Relevant Documents in
accordance with the Servicing Agreement. See "DESCRIPTION OF THE SERVICING
AGREEMENT--Document Custody."
 
COLLECTION AND ENFORCEMENT PROCEDURES
 
    Borrowers must make the minimum payment due under the terms and conditions
of the Housing Loan on or before the due date for that instalment under the
relevant loan documents. Payments are credited to the Housing Loan on the day of
receipt. Interest is calculated daily and can be charged monthly or when a
payment is made. Any payments not received by the due date will produce a
compounding interest effect.
 
    A Housing Loan is considered delinquent ("Delinquent") whenever the minimum
instalment amount is not met. The collections system inspects all accounts which
are delinquent and records those Housing Loans for action and follow-up.
Borrowers are notified by telephone and/or by mail when their Housing Loan
becomes Delinquent. Housing Loans are allocated to collections officers who take
action depending on the delinquency history, equity in the property and the
ability of the Borrower to meet future installments. Where a Housing Loan that
is Delinquent is subject to a Mortgage Insurance Policy, the relevant Mortgage
Insurer is notified of progress of the Housing Loan and all follow-up actions
are taken by Westpac and the Servicer.
 
    When a housing loan is 10 days delinquent, it is identified in the Mortgage
Servicing System and transferred to the MPC Collections System. Generally, once
a housing loan is 15 days delinquent, a computer generated letter is sent to the
borrower advising of the arrears and requesting that the borrower
 
                                       65
<PAGE>
make payments so that his account is current. When the account reaches between
23 and 29 days delinquent, the borrower may be issued a second letter or
contacted by telephone. When the account reaches between 45 and 58 days
delinquent, a third letter is generally issued which requests that the account
be made current within 15 days of the date thereof. Generally, after an account
is between 62 and 73 days overdue, a demand for full arrears is issued. Between
97 and 110 days, if the account continues to be in arrears, a demand notice will
generally be issued to the borrower and the process of contract enforcement and
loss recovery begins. The time periods specified herein assume the borrower has
either taken no action or has not honored any commitments made in relation to
the arrears.
 
    After a default by a borrower a mortgagee can exercise its power of sale of
the mortgaged property. To exercise this power, a mortgagee must comply with the
statutory restrictions of the relevant state or territory as to notice
requirements (see "CERTAIN LEGAL ASPECTS OF THE HOUSING LOANS - Enforcement of
Housing Loans"). The length of time between the decision to exercise its power
of sale and final completion of the sale will be dependent on factors outside
the control of the Servicer, such as whether the relevant mortgagor contests the
sale and the market conditions at the time.
 
    Under some Housing Loans which are subject to a variable rate of interest, a
Borrower may prepay amounts which are additional to their minimum payments to
build up a buffer of funds, which is the difference between the total amount
paid by them and the total of the minimum payments required to have been made by
them. If the Borrower subsequently fails to make some or all of a minimum
payment, the collection system will apply the amount of that buffer of funds
against that missed payment. The relevant Housing Loan will not be considered to
be Delinquent until the total amount of missed payments exceeds the "credit
buffer."
 
    Under a Housing Loan which is charged a variable rate of interest, a
Borrower who is on maternity or paternity leave and who meets specific
eligibility criteria may apply to reduce their monthly home loan repayment by up
to 50% for a maximum of six months. During the reduced repayments period, if the
payment is not sufficient to meet the interest due, the unpaid interest payment
will capitalize on the loan balance and the loan may negatively amortize.
Repayments are adjusted at the end of the parental leave period to ensure that
the loan will be repaid within its original contracted maturity.
 
    The collection and enforcement procedures may change from time to time in
accordance with business judgment and changes to legislation and guidelines
established by the relevant regulatory bodies.
 
DELINQUENCIES AND MORTGAGEE IN POSSESSION WITH RESPECT TO THE SECURITIZED
  PORTFOLIOS
 
    The following tables set forth delinquency and MIP information for each of
the Securitized Portfolios (as defined herein) serviced by the Servicer in its
capacity as Servicer of securitized loans as of December 1997 and March 1998.
"Mortgage in Possession" or "MIP" means a mortgagee in possession of the related
Mortgaged Property who, following an enforcement of the relevant mortgage, is
able to deal with the Mortgaged Property without becoming the absolute owner of
the Mortgaged Property. The portfolios of securitized housing loans (the
"Securitized Portfolios") consist of the Housing Loans relating to the Series
1997-2 WST Trust, Series 1997-3 WST Trust and the Series 1997-4E WST Trust. The
indicated periods of delinquency are based on the number of days past due on a
contractual basis. The information contained in the reports presented through
Reuters which will be sent to investors will be compiled using the same
methodology as that used to compile the information contained in the table
below.

    It is unlikely that the delinquency experience of the Housing Loans
comprising the Series 1998-1G WST Trust will correspond to the delinquency
experience of the Securitized Portfolios set forth in the foregoing tables. The
statistics shown above represent the delinquency experience for the Securitized
Portfolios only for the periods presented, whereas the aggregate delinquency
experience on the Housing Loans comprising the Securitized Portfolios will
depend on the results obtained over the life of the Securitized Portfolios.
There can be no assurance that the Housing Loans comprising the Series 1998-1G
WST Trust will perform consistently with the delinquency or foreclosure
experience described herein. It should be noted that if the residential real
estate market in Australia should experience an overall decline in property
values, the actual rates of delinquencies and foreclosures could be higher than
those previously experienced by the Servicer with respect to the Securitized
Portfolios. In addition, adverse economic conditions may affect the timely
payment by Borrowers of scheduled payments of principal and interest on the
Housing Loans and, accordingly, the actual rates of delinquencies and
foreclosures with respect to the Series 1998-1G WST Trust.

DUTIES AND ROLE OF THE TRUST MANAGER
 
POWERS
 
    The Trust Manager will carry out and perform the duties and obligations
contained in the Master Trust Deed and will have full and complete powers of
management of the Trust, including in relation to the conduct of the day to day
operation of the Trust and the administration and servicing of the assets (which
are not serviced by the Servicer), borrowings and other liabilities of the
Trusts. The Issuer Trustee has no duty to supervise the Trust Manager in the
performance of its functions and duties or the exercise of its discretion.
 
    The Trust Manager has the absolute discretion to recommend Authorized
Investments to the Issuer Trustee and direct the Issuer Trustee in relation to
those Authorized Investments. The Issuer Trustee's role is to give effect to all
such recommendations or directions.
 
DELEGATION
 
    The Trust Manager may in carrying out and performing its duties and
obligations contained in the Master Trust Deed delegate to Westpac, or any of
the Trust Manager's or Westpac's officers and employees, all acts, matters and
things (whether or not requiring or involving the Trust Manager's judgment or
discretion), or appoint any person to be its attorney, agent, delegate or
sub-contractor for such purposes and with such powers as the Trust Manager
thinks fit.
 
TRUST MANAGER'S FEES AND EXPENSES
 
    The Trust Manager is entitled to a quarterly fee (the "Trust Manager Fee")
on the average daily balance of the aggregate principal balance of Housing Loans
outstanding during the Collection Period payable in arrears on the relevant
Payment Date.
 
    The Trust Manager is entitled to be reimbursed out of the Trust Assets for
all expenses incurred in connection with the performance of its obligations in
respect of the Trust (other than general overhead costs and expenses).
 
REMOVAL OF THE TRUST MANAGER
 
    The Trust Manager shall retire as trust manager if so directed by the Issuer
Trustee following a Trust Manager's Default. A "Trust Manager's Default" occurs
if:
 
        (1) the Trust Manager fails to make any payment required by it within
    the time period specified in a Transaction Document, and that failure is not
    remedied within 10 Business Days of receipt from the Issuer Trustee of
    notice of that failure;
 
        (2) an Insolvency Event has occurred and is continuing in relation to
    the Trust Manager;
 
        (3) the Trust Manager breaches any obligation or duty imposed on the
    Trust Manager under the Master Trust Deed, any other Transaction Document or
    any other deed, agreement or arrangement entered into by the Trust Manager
    under the Master Trust Deed in relation to the Trust, the Issuer Trustee
    reasonably believes that breach has an Adverse Effect and the breach is not
    remedied within 30 days' notice being given by the Issuer Trustee (except in
    the case of reliance by the Trust Manager on the Servicer); or
 
        (4) a representation, warranty or statement by or on behalf of the Trust
    Manager in a Transaction Document or a document provided under or in
    connection with a Transaction Document, is not true in a material respect or
    is misleading when repeated and is not remedied to the Issuer Trustee's
    reasonable satisfaction within 90 days after notice from the Issuer Trustee
    where (as determined by the Issuer Trustee) it has an Adverse Effect.
 
                                       70
<PAGE>
    The costs of removal of the Trust Manager after a Trust Manager's Default
shall be borne by the Trust Manager. The Trust Manager has agreed to indemnify
the Issuer Trustee and the Trust for those costs.
 
    On retirement or removal of the Trust Manager, the Issuer Trustee may
appoint another trust manager, provided the appointment will not materially
prejudice the interests of Noteholders. Until a replacement Trust Manager is
appointed, the Trust Manager must continue as Trust Manager. If a replacement
Trust Manager is not appointed within 120 days of the Issuer Trustee electing to
appoint a new Trust Manager, the Issuer Trustee will be the new Trust Manager.
 
VOLUNTARY RETIREMENT OF THE TRUST MANAGER
 
    The Trust Manager may resign on giving to the Issuer Trustee (with a copy to
the Rating Agencies) not less than 3 months' notice in writing (or such other
period as the Trust Manager and the Issuer Trustee may agree) of its intention
to do so.
 
    Before retirement, the Trust Manager must appoint a successor Trust Manager
who is approved by the Issuer Trustee, or who may be the Issuer Trustee, and
whose appointment will not materially prejudice the interests of Noteholders. If
a successor Trust Manager has not been appointed by the end of the 3 months'
notice period the Issuer Trustee shall act as Trust Manager until a successor
trust manager is appointed.
 
LIMITATION OF TRUST MANAGER'S LIABILITY
 
    The principal limitations on the Trust Manager's liability are set out in
full in the Master Trust Deed. These include the following limitations:
 
        (1) in the absence of fraud, negligence or wilful default on its part or
    on the part of any of its officers, employees, agents or delegates, the
    Trust Manager shall not be liable personally in the event of failure to pay
    moneys on the due date for payment to any Noteholder, any Beneficiary, the
    Issuer Trustee or any other person or for any loss howsoever caused in
    respect of any of the Trusts or to any Noteholder, any Beneficiary, the
    Issuer Trustee or other person;
 
        (2) the Trust Manager will not be personally liable to indemnify the
    Issuer Trustee or make any payments to any other person in relation to the
    Trust except that there will be no limit on the Trust Manager's liability
    for any fraud, negligence or wilful misconduct by it in its capacity as the
    Trust Manager of the Trust;
 
        (3) the Trust Manager will be indemnified out of the Trust in respect of
    any liability, cost or expense properly incurred by it in its capacity as
    Trust Manager of the Trust or so incurred by any of its delegates,
    sub-delegates or agents; and
 
        (4) subject to the Master Trust Deed, the Trust Manager is not
    responsible for any act, omission, misconduct, mistake, oversight, error of
    judgment, forgetfulness or want of prudence on the part of the Issuer
    Trustee, the Servicer or any agent appointed by the Issuer Trustee or the
    Trust Manager or on whom the Issuer Trustee or the Trust Manager is entitled
    to rely under this deed (other than a related company), attorney, banker,
    receiver, barrister, solicitor, agent or other person acting as agent or
    adviser to the Issuer Trustee or the Trust Manager.
 
                        WESTPAC RESIDENTIAL LOAN PROGRAM
 
ORIGINATION OF HOUSING LOANS
 
    The primary sources for the origination of housing loans for Westpac are:
the Westpac branch network, mobile finance managers, accredited brokers and
national telemarketing centers. Inquiries are also often generated by
advertising and direct mail campaigns.
 
    The origination process for housing loans is carried out initially within
the appropriate Westpac branch or broker office. The origination process for all
housing loans is completed within the MPC.
 
                                       71
<PAGE>
UNDERWRITING OF HOUSING LOANS
 
   
    The following is a description of the underwriting processes employed by
Westpac in evaluating whether to fund a particular housing loan. When an
application is received, it is processed in accordance with Westpac's credit
policy and procedures. Credit assessment is undertaken initially using Westpac's
centrally controlled credit scoring system. The scoring system is based on
proprietary information, such as Westpac's own historical credit underwriting
experience and product policy rules. The process also includes a reference from
the Credit Reference Association of Australia. Housing loans passing through the
credit scoring system will either be approved, declined or referred to a credit
specialist. Westpac's criteria does not seek to segment borrowers who pass the
credit scoring system into groups of differing credit quality. All borrowers
must meet Westpac's standard underwriting criteria and therefore are not charged
different rates of interest based on their credit quality. Where a housing loan
is referred to a credit specialist, it is generally because the application is
more complex (for example, where the Housing Loan principal is over A$750,000 or
because the application is from a self-employed individual). An assessment is
carried out by either credit officers within the Credit Unit at the MPC or, in
some cases, by State based Credit Centers, in accordance with designated Westpac
credit policy and their credit approval limits. Each housing loan is considered
on its merits within Westpac's credit policy and procedures.
    
 
    Central to the approval process is the verification of the information
provided by the applicant(s), valuation of the proposed security property and
confirmation of the ability of the applicant to make payments on the housing
loan. The verification process involves conducting an independent check as to
the accuracy and correctness of the information provided by the potential
Borrower, particularly the documentation provided by the prospective borrower
and the employment and income details of the prospective borrower. Verification
relating to the income of self-employed applicants involves checking annual
accounts and other financial information.
 
    All applicants are required to have a minimum monthly income net of taxes in
excess of all monthly expenditures (including the housing loan being applied
for) with consideration given to likely increases in future interest rates.
 
   
    Westpac policy requires substantiation of the property value either by
contract of sale or valuation by a registered panel valuer. A valuation of the
security property is required where lender's mortgage insurance is required,
where the Housing Loan Principal is greater than A$250,000 or the LVR is greater
than 80% (although the LVR and Housing Loan Principal may be lower if the
relevant Mortgaged Property is in a particular geographic area). Valuations must
be performed by registered valuers who are members of the Australian Institute
of Valuers and Land Economists. In some remote centers, assessment of the
security value is undertaken by the local branch manager. In addition, housing
loans may be secured by more than one property and in such cases the combined
values of all relevant security properties is considered.
    
 
   
    Following pre-approval of a housing loan, a terms and conditions letter is
sent to the applicant from the MPC. When Westpac has verified details relating
to the Housing Loan to its satisfaction and acceptance of the loan offer is
received, the housing loan can proceed through to settlement and disbursement.
Once all documentation is completed to Westpac's satisfaction and settlement or
disbursement has occurred, the security documents are stamped and registered. It
is a condition of Westpac's standard mortgage documentation that the mortgagor
must maintain full replacement value property insurance at all times. Westpac
currently maintains a blanket insurance policy with Cigna Insurance Asia Pacific
Pty Limited which covers physical loss, destruction or damage to a Mortgaged
Property which is not otherwise covered by property insurance on such Mortgaged
Property.
    
 
    Approval policies are under regular review and may change from time to time
in accordance with business judgment and changes to legislation and guidelines
established by the relevant regulatory bodies.

SERVICING OF HOUSING LOANS
 
    Under the Servicing Agreement, the ongoing servicing of the Housing Loans
will be performed by the Servicer. See "THE SERVICER" and "DESCRIPTION OF THE
SERVICING AGREEMENT."
 
HOUSING LOAN PRODUCTS
 
   
    Westpac originates loans for both owner-occupied and investment housing. The
products within the housing loan portfolio are the following: Premium Option
Home Loan, Premium Option Home Loan with 1 year Guaranteed Rate, Special Offer
Fixed Option Home Loan, First Option Home Loan, Fixed Options Home Loan,
Variable Rate Investment Property Loan, Fixed Rate Investment Property Loan,
First Option Investment Property Loan and Special Fixed Rate Investment Property
Loan or any other similar loan product, however named, with some or all the
features referred to under "Housing Loan Features." During the term of any
Housing Loan, Westpac may from time to time or at the request of the related
Borrower change any of the features of such Housing Loans.
    
 
    The following provides a general description of some of the Housing Loan
products detailed above. The Housing Loans comprising the Mortgage Pool must
satisfy certain eligibility criteria as specified under "THE TRUST
FUND--Representations and Warranties."
 
OWNER OCCUPIED HOME LOANS
 
    First Option Home Loans: These loans are low variable rate owner-occupied
home loans for borrowers motivated by price. The product was developed to
compete with products offered by non-bank originators. Additional loan features
(as described below) can be activated on request by the borrower for a fee. The
current maximum term for this product is 25 years, although it may be changed to
30 years in the future.
 
    Premium Option Home Loans: These loans are variable rate owner-occupied home
loans. These loans have a maximum term to maturity of 30 years and a higher rate
of interest than the First Option Home Loan and as a result, borrowers are
allowed access to the various loan features at no or reduced additional cost.
 
    Premium Option Home Loans with 1 Year Guaranteed Rate: These loans have an
introductory discounted fixed rate for 12 months that then converts to a Premium
Option Home Loan. Apart from the introductory fixed rate period, the loan has
the same features as the Premium Option Home Loan.
 
    Special Offer Fixed Option Home Loans: These loans have a fixed rate period
of one or two years that converts to a Premium Option Home Loan. Apart from the
fixed rate period, the loan has the same features as the Premium Option Home
Loan. In 1996, this product was replaced by the Premium Option Home Loan with 1
Year Guaranteed Rate product described above.
 
   
    Fixed Options Home Loans: These loans are fixed rate owner-occupied home
loans. Loan terms are to a maximum of 30 years with a maximum fixed rate term of
10 years. On maturity of the fixed rate term, the loan converts to the Premium
Option Home Loan unless the borrower requests a further fixed rate period.
Certain product features (e.g., redraw) are not available during the fixed rate
period.
    
 
INVESTMENT PROPERTY LOANS
 
    An investment property loan is a loan which assists with the purchase or
refinance of residential property for investment purposes such as rental income
or capital gain. The primary security for the loan is a registered first party
first ranking mortgage over residential property.
 
    Investment property loans can be either fixed rate or variable rate loans
with a maximum term of 25 years. The loans may provide for interest only
payments for a maximum term of 5 years and then must convert to required payment
of principal and interest. Loans may have fixed rate terms for up to a
 
                                       73
<PAGE>
maximum of 10 years which will convert at such time to a variable rate unless
the borrower requests another fixed rate term.
 
    The First Option Investment Property Loan is a low variable rate loan which
is similar to the First Option Home Loan and the Variable Investment Property
Loan is similar to the Premium Option Home Loan, the major difference being the
loan purpose.
 
HOUSING LOAN FEATURES
 
GENERAL
 
    Housing Loans originated by Westpac may have some or all of the features
described below. In addition, during the term of any Housing Loan, Westpac may
change any of the features of such Housing Loan from time to time at the request
of the related Borrower.
 
SUBSTITUTION OF SECURITY
 
    A Borrower may apply to substitute a new Mortgage over a residential
property for an existing Mortgage, to add a further Mortgage as security for a
Housing Loan or to release a security property under a Mortgage. Provided that
the application meets certain credit criteria, the Mortgage which secures a loan
may be portable and may be discharged without full repayment of the Housing Loan
provided another acceptable Mortgage is substituted in its place.
 
    Where the substitute property meets the Eligibility Criteria and is
acceptable to the relevant Mortgage Insurer, and settlement on the substitute
property can occur simultaneously with the discharge of the current property,
the Housing Loan will remain in the Mortgage Pool. Where the substitute property
does not meet the Eligibility Criteria or is not acceptable to the Mortgage
Insurer, or the settlement does not occur simultaneously with discharge, the
Housing Loan will be transferred out of the Mortgage Pool for a corresponding
cash payment in the amount of the Unpaid Balance.
 
REDRAW
 
    Certain Housing Loans in the Mortgage Pool which are charged a variable rate
of interest have the benefit of a redraw facility which allows the Borrower to
draw on repayments made in excess of scheduled repayments (a "Redraw").
Borrowers may request a redraw at any time. In certain circumstances, Westpac
has a contractual obligation under the loan document to provide the redraw
should the Borrower be entitled to a redraw because of prepayments and the
Housing Loan is not delinquent.
 
    A Redraw will not result in the Housing Loan being removed from the Mortgage
Pool.
 
    See "DESCRIPTION OF THE OFFERED NOTES--Description of the Redraw Facility,
Redraw Funding Securities and RFS Class A Notes."
 
REPAYMENT HOLIDAY
 
    The terms of the Mortgage securing a Housing Loan which is charged a
variable rate of interest may provide for a "payment holiday." A payment holiday
can occur where the Borrower has prepaid amounts of principal, creating a buffer
of funds between the current principal balance and the amortization scheduled
balance. In such a case, the Borrower may cease to make payments until the
outstanding balance of the Housing Loan plus unpaid interest equals the balance
of the theoretical amortization schedule. Where the Housing Loan allows for a
"payment holiday", the Housing Loan payment will be taken from the buffer of
funds between the current principal balance and the amortization scheduled
balance at that payment date. If a buffer of funds is available, the system will
recognize this as an installment received. Housing Loans are not considered
Delinquent during a payment holiday and remain in the Mortgage Pool.
 
                                       74
<PAGE>
EARLY REPAYMENT
 
    Early repayment and partial prepayment of any Housing Loan is permitted
while such Housing Loan is subject to a variable rate of interest. Housing Loans
which are charged a fixed rate of interest, if repaid within their fixed rate
term, may be subject to an economic break cost or benefit in accordance with the
terms of the Housing Loan. For Housing Loans not regulated by the Consumer
Credit Legislation, an early termination fee may be payable.
 
TOP UP
 
    The loan agreement and/or Mortgage relating to a Housing Loan may allow for
the relevant Borrower to request from Westpac additional funds such that the
resulting principal balance will exceed the amortization scheduled balance at
that time. These are "top ups." Top ups will only be provided by Westpac in
accordance with its then current underwriting and credit policies. Any Housing
Loan subject to a top up will be removed from the Mortgage Pool.
 
PARENTAL LEAVE
 
    Under a Housing Loan which is charged a variable rate of interest, any
Borrower who is on maternity or paternity leave and who meets specific
eligibility criteria may apply to reduce the related monthly home loan repayment
by up to 50% of such payment amount for a maximum of six months. During the
reduced repayment period, if the payment is not sufficient to meet the interest
due, the unpaid interest payment will capitalise on the loan balance and the
loan may negatively amortize. Scheduled repayments are adjusted at the end of
the parental leave period to ensure that the loan will be repaid within its
original contracted maturity.
 
INTEREST RATE SWITCHING
 
    The interest rate charged on Housing Loans may be either fixed rate or
variable rate. Fixed rate loans will automatically convert to variable rate at
the end of the fixed rate period (as specified in the related loan agreement)
unless the relevant Borrower elects another fixed rate period. Some loans have
an introductory fixed rate of interest which converts to a variable rate of
interest at the end of such introductory period. Some loans allow the Borrower
the option to convert from a variable rate to a fixed rate (or vice versa).
 
ACCOUNT MANAGEMENT FACILITY
 
   
    A Borrower may elect to have his/her regular salary paid in full or part
into their Housing Loan account. If this amount exceeds the amortised scheduled
balance at that time, surplus funds are created therein that may be redrawn.
This feature will allow the customer in the aggregate up to fifteen automatic
disbursements in each payment cycle against these surplus funds to other
accounts. These disbursements will be treated as Redraws.
    
 
PAYMENT TYPE
 
    On the Cut-Off Date, the payment types under the Housing Loans will be
interest only or principal, interest and fees ("P & I"). Interest only periods
can be for terms of 1-5 years. At the end of any interest only period, the
payment type under the relevant Housing Loan will convert to P & I payments such
that the scheduled payments will result in the Housing Loan being repaid on an
amortizing schedule within the contractual term of the Housing Loan.
 
SWITCHING TO AN INVESTMENT OR OWNER-OCCUPIED LOAN
 
    The Borrower may elect to switch the purpose of a Housing Loan from
owner/occupied property finance to investment property finance or vice versa.
Any such switch will not require the relevant Housing
 
                                       75
<PAGE>
Loan to be removed from the Mortgage Pool. The Borrower is required to notify
Westpac of such switch and the Mortgage Rate with respect to such Housing Loan
may be changed accordingly.
 
CAPITALIZED FEES
 
    Westpac may offer Borrowers the ability to choose certain product features
without paying an up-front fee. Instead, the fee may be capitalized under the
Housing Loan and would constitute part of the principal to be amortized over the
life of the Housing Loan.
 
COMBINATION HOUSING LOANS
 
    A Borrower may split his/her Housing Loan into different portions which may
(among other things) be subject to different interest rate options. This could
occur, for example, where a Borrower elects to have one part of their Housing
Loan at a fixed rate and the other at a variable rate. Each loan is effectively
a separate loan which operates independently of the other loans in the combined
product and is governed by its own policy and procedures.
 
    If a Housing Loan is "split" into more than one loan, any newly created
loans will not form part of the pool. In the event that the original loan is
retained (potentially at a reduced balance) in certain circumstances (e.g., it
satisfies all Eligibility Criteria and does not have any feature that would
require it to be removed from the pool) it will remain in the pool.
 
ADDITIONAL FEATURES
 
    Westpac may, in relation to a Housing Loan in the Mortgage Pool, from time
to time seek to offer additional features which are not referred to above.
Before doing so, Westpac must satisfy the Trust Manager that the additional
features would not affect any relevant Mortgage Insurance Policy and would not
cause the rating of any Offered Notes to be downgraded or withdrawn.
 
                        THE MORTGAGE INSURANCE POLICIES
 
MORTGAGE INSURANCE POLICIES--GENERAL
 
    On or before the Closing Date, the Mortgage Pool Insurance Policy will be
provided by Housing Loans Insurance Corporation Limited of 31 Market Street,
Sydney NSW 2000, Australia ("HLIC") to the Issuer Trustee to cover losses in
respect of each Housing Loan that is not subject to a PMI Policy. The Mortgage
Pool Insurance Policy generally applies to loans with an LVR of 80% or less at
the Cut-Off Date. The Mortgage Pool Insurance Policy will cover losses up to a
maximum aggregate amount of A$      .
 
    Each Housing Loan with an LVR of greater than 80% at the time of origination
(or a lower LVR where required by Westpac's standard credit policy) will have
been insured under a PMI Policy issued by SunAlliance and Royal Mortgage
Insurance Limited (ACN 001 825 725) of Level 9, 465 Victoria Avenue, Chatswood
NSW ("SunAlliance"), MGICA Limited (ACN 000 511 017) of Level 23 AMP Centre, 50
Bridge Street, Sydney NSW ("MGICA"), Westpac Lenders Mortgage Insurance Limited
(ACN 074 042 934) of Level 11, 50 Pitt Street, Sydney NSW ("WLMI") or HLIC. Each
Approved Seller will equitably assign its interest in each PMI Policy to the
Issuer Trustee on the Closing Date.
 
THE HLIC MORTGAGE POOL INSURANCE POLICY
 
    GENERAL
 
    The HLIC Mortgage Pool Insurance Policy (the "Mortgage Pool Insurance
Policy") is an insurance policy put in place to cover Housing Loans that were
not insured prior to the Cut-Off Date and which had an LVR of less than or equal
to 80% as of the Cut-Off Date. Under the Mortgage Pool Insurance Policy, HLIC
will insure the Issuer Trustee with effect from the Closing Date for Finance
Charge Losses and Principal Losses in respect of the Housing Loans (other than
those Housing Loans which are individually
 
                                       76
<PAGE>
covered by an HLIC, a SunAlliance, WLMI or an MGICA Insurance Policy) (see
"--Primary Mortgage Insurance Policies" below).
 
PERIOD OF COVER
 
    The Issuer Trustee has the benefit of the Mortgage Insurance Policy in
respect of each Housing Loan from the date the Housing Loan and the relevant
Mortgage are beneficially assigned to it until the earliest of:
 
        (i) other than with respect to the assignment to the Security Trustee
    under the Security Trust Deed, the date the Housing Loan or the relevant
    Mortgage is assigned, transferred or mortgaged to a person other than a
    person who is or becomes insured under the Mortgage Pool Insurance Policy;
 
        (ii) the date the Housing Loan is repaid in full;
 
       (iii) the date the Housing Loan ceases to be secured by the relevant
    Mortgage (other than in the case where the Mortgage is discharged by the
    operation of a compulsory acquisition or sale by a government for public
    purposes);
 
        (iv) the maturity date set out in the "Certificate of Insurance" (as
    defined in the Mortgage Pool Insurance Policy), or as extended with the
    consent of the Mortgage Insurer or as varied by a court under the Consumer
    Credit Legislation; and
 
        (v) the date the Mortgage Pool Insurance Policy is cancelled in respect
    of the Housing Loan in accordance with the Mortgage Pool Insurance Policy.
 
COVER FOR LOSSES
 
    HLIC is obliged to pay to the Issuer Trustee the loss as at the Loss Date
(as defined herein) in respect of a Housing Loan, being the aggregate of:
 
        (i) the principal amount outstanding under such Housing Loan together
    with any interest, fees or charges (whether capitalized or not), that are
    outstanding at the Loss Date;
 
        (ii) fees and charges paid or incurred by the Issuer Trustee; and
 
       (iii) such other amounts (including fines or penalties) which HLIC
    approves in its absolute discretion; which the Issuer Trustee is entitled to
    recover under the relevant Housing Loan contract and Mortgage less
    deductions including:
 
        (iv) any sale proceeds or compensation for compulsory acquisition of the
    Mortgaged Property;
 
        (v) in the event of foreclosure, the value of the Issuer Trustee's
    interest in the Mortgaged Property;
 
        (vi) any amount received by the Issuer Trustee under any collateral
    security;
 
       (vii) amounts paid to the Issuer Trustee by way of rents, profits or
    proceeds in relation to the Mortgaged Property or under any policy of
    insurance relating to the Mortgaged Property not applied in restoration or
    repair;
 
      (viii) any interest whether capitalized or not that exceeds interest at
    the (non-default) interest rate (in accordance with the Consumer Credit
    Legislation, if applicable) payable in relation to that Housing Loan;
 
        (ix) any fees or charges, whether capitalized or not, that are not of a
    type, or which exceed certain maximum amounts, as specified in the Mortgage
    Pool Insurance Policy;
 
        (x) losses directly arising out of physical damage to the Mortgaged
    Property (other than from fair wear and tear or losses recovered and applied
    in the restoration or repair of the Mortgaged Property prior to the Loss
    Date or which were recovered under a policy of insurance and applied to
    reduce the amount outstanding under the Housing Loan; and
 
                                       77
<PAGE>
        (xi) any amounts by which a claim may be reduced under the Mortgage Pool
    Insurance Policy.
 
   
    "Loss Date" means, in respect of a Housing Loan:
    
 
        (a) where, following an event on or following which the Approved Seller
    or the Issuer Trustee's power of sale in relation to the relevant Mortgaged
    Property becomes exercisable whether immediately or at the option of the
    Approved Seller or the Issuer Trustee or upon the expiration of any notice
    or period of time and whether or not the power of sale only arises if before
    the expiration of the notice or period of time the default remains
    unremedied (a "Mortgage Default"), the Approved Seller or the Issuer Trustee
    or a prior mortgagee in respect of the Mortgaged Property sells the
    Mortgaged Property, the date on which the sale is completed;
 
        (b) where, following a Mortgage Default, the Approved Seller or the
    Issuer Trustee or a prior mortgagee in respect of the Mortgaged Property
    becomes the absolute owner by foreclosure, the date on which that event
    occurs;
 
        (c) where, following a Mortgage Default, the Borrower sells the
    Mortgaged Property with the prior approval of the Approved Seller, the
    Issuer Trustee and HLIC, the date on which the sale is completed;
 
        (d) where the Mortgaged Property is compulsorily acquired or sold by a
    government for public purposes and there is a Mortgage Default (or where the
    Mortgage has been discharged by the operation of the compulsory acquisition
    or sale and there is a default in repayment of the loan secured by the
    Mortgage which would have been a Mortgage Default but for the occurrence of
    that event), the date being the later of the date of the completion of the
    acquisition or sale or the date twenty-eight days after the date of the
    Mortgage Default; and
 
        (e) where the HLIC has agreed or determined to pay a claim under the
    Mortgage Pool Insurance Policy, the date specified in that agreement or
    determination.
 
    If the Consumer Credit Legislation applies to a Mortgage, HLIC's liability
is limited to the amount required to discharge the mortgage under the Consumer
Credit Legislation.
 
AGGREGATE LIMIT
 
    The Mortgage Pool Insurance Policy will be subject to an aggregate limit of
loss of A$      .
 
ISSUER TRUSTEE'S INTEREST EXTINGUISHED
 
    If the Issuer Trustee's interest in a Housing Loan is extinguished in favor
of Westpac as a result of:
 
    (1) a breach of Westpac's representations and warranties in relation to the
Housing Loan which is discovered within 120 days of the Closing Date (or, in
relation to Housing Loans assigned to the Issuer Trustee from the assets of
another Seller Trust, 120 days after the date on which those Housing Loans were
first sold by Westpac to the Issuer Trustee in its capacity as trustee of other
Seller Trusts) and which breach was not remedied within that period (see
"WESTPAC RESIDENTIAL LOAN PROGRAM--Eligibility Criteria"); or
 
    (2) a repurchase of a Housing Loan in accordance with Westpac's right of
first refusal, then Westpac will be entitled to the benefit of the Mortgage Pool
Insurance Policy in so far as it applies to that Housing Loan.
 
REFUSAL OR REDUCTION IN CLAIM
 
    The amount of a claim may be reduced or cancelled by HLIC in the following
circumstances:
 
        (i) any premium is not paid within twenty-eight days of the due date
    therefor;
 
        (ii) The Housing Loan contract for the relevant Mortgaged Property does
    not require the Mortgaged Property to be insured under a general insurance
    policy;
 
                                       78
<PAGE>
       (iii) there ceases to be a Servicer approved by HLIC to service the
    Housing Loans for the Issuer Trustee;
 
        (iv) a claim is not lodged within twenty-eight days of the relevant Loss
    Date;
 
        (v) there is any representation or statement (deemed or otherwise) in a
    proposal for a Pool Mortgage Insurance Policy that is incorrect or the duty
    of disclosure under the Mortgage Pool Insurance Policy is breached;
 
        (vi) the Issuer Trustee or the Servicer does not comply with the
    reporting obligations under the Mortgage Pool Insurance Policy;
 
       (vii) the relevant Mortgage has not been duly registered with the land
    titles office in the jurisdiction where the related Mortgaged Property is
    located; and
 
      (viii) the Housing Loan contract, the Mortgage or any collateral security
    for the relevant Mortgaged Property has not been duly stamped, or the stamp
    duty thereon has not been paid, in each relevant jurisdiction.
 
    Under the Servicing Agreement, the Servicer undertakes to perform (and
indemnifies the Issuer Trustee against) certain obligations of the Issuer
Trustee, including the Issuer Trustee's duties of disclosure and its reporting
obligations under the Mortgage Pool Insurance Policy. See "-Servicer
Undertakings with Respect to Insurance Policies". This arrangement is
acknowledged in the Mortgage Insurance Policy.
 
    Circumstances in which claims under a Mortgage Insurance Policy may be
reduced or cancelled also include the following events occurring in relation to
the Issuer Trustee without the approval of the Mortgage Insurer:
 
        (i) the making of any additional advance (other than Redraws) upon the
    security of a Mortgaged Property that ranks for payment ahead of the Housing
    Loan;
 
        (ii) materially altering the terms of a Housing Loan contract, any
    related Mortgage or any collateral security other than an alteration made in
    accordance with the Consumer Credit Legislation;
 
       (iii) allowing its rights to be reduced against the Borrower, the
    relevant mortgagor, any mortgage guarantor, any provider of any collateral
    security or the Mortgaged Property by compromise, postponement, partial
    discharge or otherwise;
 
        (iv) approving any transfer or assignment of the Mortgaged Property
    without full discharge of the Housing Loan;
 
        (v) a violation by the Issuer Trustee of any provision of such Mortgage
    Pool Insurance Policy; and
 
        (vi) consenting to a further advance by a prior mortgagee previously
    approved by HLIC upon the security of an approved prior mortgage.
 
EXCLUSIONS
 
    The Mortgage Insurance Policy does not cover any loss arising from:
 
        (i) any war or warlike activities;
 
        (ii) nuclear contamination;
 
       (iii) the existence or escape of any pollution or environmentally
    hazardous material;
 
        (iv) the fact that the Housing Loan contract, the relevant Mortgage or
    any collateral security is void or unenforceable; or
 
        (v) where the Consumer Credit Legislation applies, any failure of the
    Housing Loan contract, the relevant Mortgage or any collateral security to
    comply with the requirements of the Consumer
 
                                       79
<PAGE>
    Credit Legislation. See "CERTAIN LEGAL ASPECTS OF THE HOUSING
    LOANS--Consumer Credit Legislation."
 
CLAIMS
 
    A claim may only be made under the Mortgage Pool Insurance Policy following
the Loss Date for the relevant Mortgage. If a Housing Loan has been in default
for at least 6 months HLIC may in its absolute discretion pay the claim for the
loss even if the Loss Date has not occurred. Claims are payable within 14 days
of receipt by HLIC of the completed claim form.
 
   
    HLIC may, as a condition to payment of a claim, require an assignment to it
by the Issuer Trustee (at the Issuer Trustee's expense) of rights against the
Borrower or any mortgagor or require the Issuer Trustee to take action, or
empower HLIC, in relation to the relevant Housing Loan or related Mortgage.
    
 
VARIATIONS
 
    HLIC may not vary the Mortgage Insurance Policy for any Housing Loan except
where the variation is generally applied to all insured customers of the same
type in relation to the same type of insurance and where the variation is
necessitated to ensure that, as a consequence of a change in law after the date
of the Mortgage Insurance Policy, HLIC is not in breach of the law.
 
HOUSING LOAN INSURANCE CORPORATION LTD (HLIC LTD)
 
   
    HLIC was established in 1965 by the Commonwealth Government of Australia
("Government") and is Australia's leading lenders' mortgage insurer ("LMI") with
approximately 50% of the Australian LMI market. In December 1997, the Government
sold HLIC to GE Capital Australia ("GECA") which is a wholly owned subsidiary of
GE Capital Services Inc. ("GE").
    
 
    GE is a diversified industrial and financial services company with
operations in over 100 countries. It is rated AAA by Standard & Poor's, Aaa by
Moody's and AAA by Fitch IBCA. It has significant LMI business around the world,
operating in the United States, United Kingdom, Canada and now Australia and has
over US$165 billion of loans insured globally.
 
   
    HLIC has been given a AAA claims paying rating in its own right by Standard
& Poor's, a Aa1 rating by Moody's and a AAA rating by Fitch. Loans insured prior
to the sale to GECA will also have the benefit of a guarantee by the Government.
That proportion that has the benefit of the Government guarantee is $         as
of the Cut-Off Date.

PRIMARY MORTGAGE INSURANCE POLICIES
 
GENERAL
 
   
    Each Borrower under a Housing Loan which had an LVR of greater than 80% at
the date of origination (or a lower LVR where required by Westpac's standard
credit policy) was required to effect a mortgage insurance policy with either
SunAlliance, MGICA, WLMI or [HLIC] (a "PMI Policy"). Westpac is required to
equitably assign its interest in each Primary Mortgage Insurance Policy to the
Issuer Trustee on the Closing Date. The consent of SunAlliance, MGICA, WLMI and
[HLIC] is required for the assignment of the relevant Mortgages and the Primary
Mortgage Insurance Policies, and for the Servicer to service the insured Housing
Loans. Westpac must ensure that these consents are obtained on or prior to the
Closing Date.
    
 
   
    [Where a provision of the HLIC PMI Policy is inconsistent with the HLIC
Mortgage Pool Insurance Policy, the provision in the HLIC Mortgage Pool
Insurance Policy will be taken to apply to the HLIC PMI Policy.]
    
 
   
    [The HLIC Mortgage Pool Insurance Policy provides for the assignment to the
Trust of any HLIC PMI Policy.]
    
 
RESTRICTIONS AND CANCELLATION
 
    The amount recoverable under each PMI Policy will generally be the amount
owing in relation to the relevant Mortgage (including unpaid principal, accrued
interest at any non-default rate, proper tax and reasonable enforcement costs
(subject in certain instances to insurer's consent)) less all amounts recovered
from enforcement of the Mortgage. However, there are a number of requirements
and restrictions imposed on the insured under each PMI Policy which may entitle
the Mortgage Insurer to cancel the PMI Policy or reduce the amount of a claim;
including:
 
        (1) the existence of an encumbrance or other interest which affects or
    has priority over the Mortgage;
 
        (2) the relevant Mortgage, or a guarantee or indemnity relating to the
    Mortgage, ceasing to be effective;
 
        (3) that there is a material omission or misstatement by the insured in
    relation to the Primary Mortgage Insurance Policy;
 
        (4) that any premium is not paid within the relevant grace period (if
    any);
 
        (5) termination by the insurer upon the giving of a set period of
    notice;
 
        (6) a breach by the insured of the PMI Policy; and
 
        (7) certain circumstances which affect the insured's rights or
    recoveries under the relevant Housing Loan or Mortgage.
 
    Each PMI Policy has different provisions. The above is a summary of certain
provisions--some may not relate to, or may differ from, a particular PMI Policy.
 
SERVICER UNDERTAKINGS WITH RESPECT TO INSURANCE POLICIES
 
    Under the Servicing Agreement, the Servicer undertakes to:
 
        (1) act in accordance with the terms of any Mortgage Insurance Policy;
 
        (2) not do anything that would prejudicially affect the rights of the
    Issuer Trustee under a Mortgage Insurance Policy; and
 
        (3) promptly make claims and notify the Trust Manager when claims are
    made.

                   PRINCIPAL PAYMENT AND YIELD CONSIDERATIONS
    
 
   
    The following information is given solely to illustrate the effect of
principal payments of the Housing Loans on the weighted average life of the
Offered Notes under the stated assumptions and is not a prediction of the
principal payment rate that might actually be experienced by the Housing Loans.
    
 
GENERAL
 
    The rate of principal payments on the Offered Notes, the aggregate amount of
distributions on the Offered Notes and the yield to maturity of the Offered
Notes will be related to the rate and timing of payments of principal on the
Housing Loans. The rate of principal payments on the Housing Loans will in turn
be affected by the amortization schedules of the Housing Loans and by the rate
of principal prepayments (including for this purpose prepayments resulting from
refinancing, liquidations of the Housing Loans due to defaults, casualties,
condemnations and repurchases by an Approved Seller). The Housing Loans may be
prepaid by the Mortgagors at any time (subject, in the case of fixed rate
Housing Loans, to the payment of any applicable fees).
 
                                       82
<PAGE>
   
PRINCIPAL PAYMENTS
    
 
   
    Principal payments, liquidations and purchases of the Housing Loans
(including optional purchase of the remaining Housing Loans in connection with
the termination of the Trust) will result in distributions on the Offered Notes
of principal amounts which would otherwise be distributed over the remaining
terms of such Housing Loans. Since the rate of payment of principal of the
Housing Loans will depend on future events and a variety of factors, no
assurance can be given as to such rate or the rate of principal payments. The
extent to which the yield to maturity of any Offered Note may vary from the
anticipated yield will depend upon the degree to which a Note is purchased at a
discount or premium, and the degree to which the timing of payments thereon is
sensitive to scheduled payments, prepayments, liquidations and purchases of such
Housing Loans. The rate of principal payment on the Housing Loans cannot be
predicted. The prepayment experience of the Trust with respect to the Housing
Loans may be affected by a wide variety of factors, including economic
conditions, the availability of alternative financing and homeowner mobility.
    
 
   
WEIGHTED AVERAGE LIVES
    
 
   
    Generally, greater than anticipated payments of principal will increase the
yield on Offered Notes purchased at a price less than par and will decrease the
yield on Offered Notes purchased at a price greater than par. The effect on an
investor's yield due to principal payments on the Housing Loans occurring at a
rate that is faster (or slower) than the rate anticipated by the investor in the
period immediately following the issuance of the Notes will not be entirely
offset by a subsequent like reduction (or increase) in the rate of principal
payments. Principal payments and therefore the weighted average life of the
Offered Notes will be affected by the amount and timing of delinquencies and
defaults on the Housing Loans and the recoveries, if any, on defaulted Housing
Loans and foreclosed properties.
    
 
    The "weighted average life" of a Note refers to the average amount of time
that will elapse from the date of issuance of the Note to the date each dollar
in respect of principal repayable under such Note is reduced to zero. The
weighted average life of the Offered Notes will be influenced by, among other
factors, the rate at which principal payments are made on the Housing Loans.
 
   
    The following tables are based on a constant payment rate model ("CPR"). CPR
is a constant rate of principal payment, combining both scheduled repayments as
well as unscheduled prepayments, with no principal increases or redraws granted.
CPR differs from the CONSTANT PREPAYMENT MODEL commonly applied in U.S. mortgage
transactions where scheduled payments are NOT included. CPR represents an
assumed constant rate of payment each month, expressed as a per annum percentage
of the principal balance of the pool of mortgage loans for that month. CPR does
not purport to be a historical description of payment experience or a prediction
of the anticipated rate of payment of any pool of housing loans, including the
Housing Loans. None of the Approved Sellers, the Trust Manager nor the Issuer
Trustee believes that any existing statistics of which it is aware provide a
reliable basis for holders of Offered Notes to predict the amount or the timing
of receipt of payments on the Housing Loans.
    
 
   
    Since the following tables were prepared on the basis of the assumptions in
the following paragraph, there are discrepancies between characteristics of the
actual Housing Loans and the characteristics of the Housing Loans assumed in
preparing the tables. Any such discrepancy may have an effect upon the
percentages of the principal balances outstanding and weighted average lives of
the Offered Notes set forth in the tables. In addition, since the actual Housing
Loans in the Trust have characteristics which differ from those assumed in
preparing the tables set forth below, the distributions of principal on the
Offered Notes may be made earlier or later than as indicated in the tables.
    
 
   
    For the purpose of the tables below, it is assumed that: (i) the Closing
Date for the Offered Notes is June       , 1998, (ii) payments on the Offered
Notes are made on the 19th day of each Quarter regardless of the day on which
the Payment Date actually occurs, commencing in July 1998 and are made in
accordance with the priorities described herein, (iii) the scheduled monthly
payments of principal and interest on the Housing Loans will be timely delivered
on the first day of each month commencing in
    
 
                                       83
<PAGE>
   
July 1998 (with no defaults), (iv) all principal payments are payments in full
received on the last day of each month and include 30 days' interest thereon,
(v) no optional termination is exercised and (vi) the Offered Notes have the
Interest Rate and initial principal balances set forth herein. The preceding
clauses are the assumptions used in preparing the following tables and are not
necessarily expected to be predictive of the Mortgage Pool's actual performance.
    
 
   
    It is not likely that the Housing Loans will pay at any constant multiple of
the assumed CPR to maturity or that all Housing Loans will pay at the same rate.
In addition, the diverse remaining terms to maturity of the Housing Loans (which
include recently originated Housing Loans) could produce slower distributions of
principal than as indicated in the tables at the multiples of CPR specified,
even if the weighted average remaining term to maturity of the Housing Loans is
the same as the weighted average remaining term to maturity of the assumptions
described above. Investors are urged to make their investment decisions on a
basis that includes their determination as to anticipated principal payment
rates under a variety of the assumptions discussed herein as well as other
relevant assumptions.
    
 
   
    In the following tables the weighted average life of each Class was
determined on the basis of the calculation of CPR as defined herein, which
differs from the way weighted average lives are calculated in U.S. mortgage
transactions where scheduled payments are not included.

    amount of each payment of principal thereof by the number of years from the
    date of issuance to the related Payment Date, (b) summing the results and
    (c) dividing the sum by the aggregate distributions of principal referred to
    in clause (a) and rounding to one decimal place.
 
                        DESCRIPTION OF THE OFFERED NOTES
 
GENERAL
 
   
    The Notes will be issued pursuant to the terms of the Transaction Documents.
The following section contains summaries of the material terms of the
Transaction Documents. The summaries do not purport to be complete and are
subject to the provisions of the Transaction Documents. A copy of the Master
Trust Deed, and a form of each of the Series Notice, the Note Trust Deed and the
Security Trust Deed has been filed with the Commission as an Exhibit to the
Registration Statement of which this Prospectus is a part.
    
 
   
    Pursuant to the Transaction Documents, on the Closing Date the Issuer
Trustee will issue two classes of notes (the "Offered Notes"), consisting of one
class of senior notes, designated as the Class A Mortgage Backed Floating Rate
Notes due [July][October] 19,     , in the original principal amount of
US$[      ] (the "Class A Notes") and one class of subordinated notes,
designated as the Class B Mortgage Backed Floating Rate Notes, due
[July][October] 19,     , in the original principal amount of US$[      ] (the
"Class B Notes"). In addition to the Class A Notes and the Class B Notes, the
Issuer Trustee may from time to time issue RFSs, which may convert to RFS Class
A Notes in certain circumstances. The Offered Notes, the RFSs and the RFS Class
A Notes are referred to herein as the "Notes." See "--Description of the Redraw
Facility, the Redraw Funding Securities and the RFS Class A Notes" herein.
    
 
   
    Payments on the Notes will be made by the Note Trustee on each Payment Date
to persons in whose names the Notes are registered as of the related Record Date
(the "Holders" or "Noteholders"). The Payment Date for the Notes will be the
19th day of each Quarter. A "Quarter" is each three-month period in a year which
period begins on July 1, October 1, January 1 and April 1. If any Payment Date
would otherwise fall on a day which is not a Business Day, it shall be postponed
to the next day which is a Business Day unless it would thereby fall into the
next calendar month in which event it shall be brought forward to the
immediately preceding Business Day. The first Payment Date will be July 20, 1998
in respect of the period from (and including) the Closing Date to (but
excluding) that date. The Record Date for any Payment Date will be the second
Business Day immediately preceding the Payment Date (so long as the Notes are
held in book-entry form), or the last day of the prior calendar month (if
Definitive Notes have been issued).
    
 
   
    A "Business Day" means (1) in relation to the Note Trust Deed, the Agency
Agreement and any Note, any day, other than a Saturday, Sunday or public
holiday, on which banks are open for business in Sydney, London and New York
City; and (2) in relation to any other Transaction Document, any day, other than
a Saturday, Sunday or public holiday, on which Banks are open for business in
Sydney. If a public holiday is occurring in any of the referenced locales, then
such day is not a Business Day, and no scheduled payments will be made on such
day.
    
 
   
    A "Collection Period" commences on and includes the 10th day of each Quarter
and runs until (and includes) the 9th day of the following Quarter with the
exception of the first Collection Period, which will commence on (and include)
the day after the Cut-Off Date and end on (and include) [July 9], 1998.
    
 
   
    The first Interest Period in relation to the Notes commences on (and
includes) the Closing Date and ends on (but excludes) the first Payment Date
(being [July 20], 1998). Each succeeding Interest Period, commences on (and
includes) a Payment Date and ends on (but excludes) the next Payment Date. The
final Interest Period ends on (but excludes) the Maturity Date.
    
 
                                       85
<PAGE>
   
    For any Interest Period other than the initial Interest Period, the
"Interest Determination Date" is the second Business Day prior to the
commencement of that Interest Period. The initial Interest Determination Date is
July 17, 1998. The "Collection Determination Date" is four Business Days prior
to each Payment Date.
    
 
    Each Class of Offered Notes initially will be represented by one or more
global notes (the "Book-Entry Notes") registered in the name of the nominee of
DTC (together with any successor depository selected by the Note Trustee, the
"Depository"), except as set forth below. Beneficial interests in each Class of
Offered Notes will be available for purchase in minimum denominations of
US$100,000. The Issuer Trustee has been informed by DTC that DTC's nominee will
be Cede & Co. Accordingly, Cede & Co. is expected to be the Noteholder of record
of the Offered Notes. Unless and until Definitive Notes are issued under the
limited circumstances described herein, no Note Owner (as defined herein)
acquiring an interest in any Class of Offered Notes will be entitled to receive
a certificate representing such Note Owner's interest in such Notes. Until such
time, all references herein to actions by Noteholders of any Class of Offered
Notes will refer to actions taken by the Depository upon instructions from its
participating organizations and all references herein to distributions, notices,
reports and statements to Noteholders of any Class of Offered Notes will refer
to distributions, notices, reports and statements to the Depository or its
nominee, as the registered Noteholder of such Class, for distribution to Note
Owners of such Class in accordance with the Depository's procedures. See
"--Book-Entry Registration" and "--Definitive Notes."
 
   
    The Issuer Trustee will maintain a Paying Agent in London until the date the
Offered Notes are redeemed.
    
 
COLLECTIONS AND PAYMENT
 
   
    With respect to each Collection Period and on or prior to the Collection
Determination Date, the Trust Manager will determine the Collections (as defined
below) received and reconcile such receipts against expenses, including Interest
payable to Noteholders, that have accrued during such Collection Period. To the
extent necessary, the Trust Manager must direct the Issuer Trustee to draw on or
claim against the Liquidity Facility where available to make up shortfalls in
Collections due but not received. Various amounts will also be swapped under the
Swap Agreements.
    
 
    On the Collection Determination Date, the Trust Manager shall advise the
Issuer Trustee of the amounts to be paid. The Issuer Trustee will arrange for
the relevant payments to occur on the Payment Date.
 
    Set out below is an example of relevant dates and periods for the allocation
of cashflows and their payments. All dates are assumed to be Business Days.

COLLECTIONS
 
    With respect to any Collection Period, "Collections" shall consist of
interest and principal receipts from the Housing Loans, the proceeds of
enforcement of Mortgages, the proceeds of claims under Mortgage Insurance
Policies and payments by the Approved Sellers or the Servicer in respect of
breaches of representations or warranties with respect to the Housing Loans.
Westpac or the Servicer, as a delegate
 
                                       86
<PAGE>
of Westpac under the Servicing Agreement, will receive the Collections in
respect of the Housing Loans in the Mortgage Pool.
 
   
    So long as both (a) Westpac has a short term rating of at least A-1+ from
Standard & Poor's, P-1 from Moody's and F-1+ from Fitch and (b) the Collections
Account is maintained with Westpac or a subsidiary of Westpac, each of Westpac
and the Servicer shall deposit the amount equal to the Collections it receives
during the related Collection Period into the relevant Collections Account two
Business Days prior to the relevant Payment Date (the "Remittance Date")
together with an amount equivalent to the interest that would have accrued at
the Bank Bill Rate on such amounts if such receipts had been deposited into the
Collections Account five Business Days following receipt by Westpac or the
Servicer (less any relevant tax).
    
 
   
    If Westpac has a short term rating of less than A-1+ from Standard & Poor's,
less than P-1 from Moody's and less than A-1+ from Fitch, then Westpac and the
Servicer shall pay all Collections in its possession or control into the
Collections Account no later than five Business Days following receipt.
Notwithstanding the foregoing, the Collections Account may continue to be
maintained with Westpac for so long as it is an Approved Bank. An "Approved
Bank" means: (a) a Bank which has a short term rating of at least A-1+ from
Standard & Poor's, P-1 from Moody's and F-1+ from Fitch; or (b) any bank or
financial institution which is specified to be an Approved Bank in the Series
Notice, but means Westpac for so long as it has a short term rating of A-1 or
better from Standard & Poor's.
    
 
   
    If, however, the Collections Account is not maintained with Westpac, or a
subsidiary of Westpac, all Collections in relation to the Trust must be
deposited into the Collections Account no later than two Business Days following
receipt thereof by Westpac or the Servicer (as the case may be).
    
 
CALCULATION OF TOTAL AVAILABLE FUNDS
 
   
    On each Collection Determination Date the Trust Manager will, for the
immediately preceding Collection Period, calculate the total of the Available
Income, plus Principal Draws, plus Liquidity Draws (the sum of such amounts, the
"Total Available Funds"), all as further described below.
    
 
AVAILABLE INCOME
 
    "Available Income" for a Collection Period equals the aggregate of:
 
   
        (1) Finance Charge Collections plus to the extent not included in this
    paragraph (1):
    
 
        (2) any amount received or due to be received by or on behalf of the
    Issuer Trustee with respect to net receipts under any Swap Agreement (other
    than the Currency Swap);
 
        (3) any amount received by or on behalf of the Issuer Trustee under any
    Support Facility (other than the Currency Swap), including under a Mortgage
    Insurance Policy, which the Trust Manager determines should be accounted for
    in respect of a Finance Charge Loss;
 
        (4) any interest income received by or on behalf of the Issuer Trustee
    in respect of moneys credited to the Collections Account in relation to the
    Trust;
 
        (5) amounts in the nature of interest otherwise paid by Westpac, the
    Servicer or the Trust Manager to the Issuer Trustee in respect of
    Collections held by it;
 
   
        (6) any net amount attributable to income from another WST trust
    established under the Master Trust Deed with respect to the substitution of
    a Housing Loan ("Substitution Net Transfer Amount (Income)"); and
    
 
        (7) all other amounts received by or on behalf of the Issuer Trustee in
    respect of the Trust assets in the nature of income,
 
    excluding
 
        (8) any interest credited to a Collateral Account for a Support
    Facility; and
 
                                       87
<PAGE>
   
        (9) any amount received by the Issuer Trustee on entry into a
    replacement Currency Swap which is payable to the prior Currency Swap
    Providers.
    
 
    "Finance Charge Collections" shall equal:
 
        (1) all amounts received by or on behalf of the Issuer Trustee in
    respect of interest, fees and other income payable under Housing Loans in
    the Mortgage Pool, including:
 
        (i) amounts on account of interest recovered from the enforcement of a
            Housing Loan;
 
        (ii) any payments by Westpac to the Issuer Trustee on the repurchase of
             a Housing Loan which are attributable to interest;
 
       (iii) any interest adjustments received by the Trust in relation to the
             transfer of Housing Loans or related Mortgages from the Trust to
             another WST trust; and
 
        (iv) the Prepayment Cost Surplus for that Collection Period (if any);
             and
 
        (2) all amounts in respect of interest, fees and other amounts in the
    nature of income, received by or on behalf of the Issuer Trustee during that
    Collection Period including:
 
        (i) from an Approved Seller or the Servicer in respect of any breach of
            a representation, warranty or undertaking contained in the Master
            Trust Deed, Servicing Agreement or Series Notice;
 
        (ii) from an Approved Seller or the Servicer under any obligation under
             the Master Trust Deed, Servicing Agreement or Series Notice to
             indemnify or reimburse or pay damages to the Issuer Trustee for any
             amount, in each case which are determined by the Trust Manager to
             be in respect of interest; and
 
        (3) any amount received in respect of a Housing Loan in the Mortgage
    Pool, or a related Mortgage, after a Finance Charge Loss has occurred, which
    has not been received under a Mortgage Insurance Policy and which is not
    payable to an insurer under a Mortgage Insurance Policy; less
 
        (4) any amount debited in respect of the Housing Loans in the Mortgage
    Pool representing government charges collected by or on behalf of the Issuer
    Trustee, financial institutions duty, bank accounts debit tax or similar
    taxes and fees or charges due to the Servicer or Westpac under the Housing
    Loans and the Prepayment Cost Surplus due to Westpac and collected by
    Westpac or the Servicer.
 
    With respect to any Housing Loan, a "Finance Charge Loss" means Liquidation
Losses which are attributable to interest, fees and expenses in relation to the
relevant Housing Loan including on the early discharge of Housing Loans which
bear a fixed rate of interest (other than a Housing Loan subject to a
concessional rate of interest for 12 months or less) the amount, if any, owed by
the relevant Borrower in accordance with the Relevant Documents. With respect to
any Housing Loan, "Liquidation Losses" for a Collection Period, means the amount
(if any) by which the Unpaid Balance of a Housing Loan (together with the
enforcement expenses relating to the Housing Loan and the related Mortgage)
exceeds the Liquidation Proceeds in relation to the Housing Loan. "Liquidation
Proceeds" means all amounts recovered from the enforcement of a Mortgage
(excluding proceeds of a Mortgage Insurance Policy).
 
    With respect to any Housing Loan, a "Prepayment Cost Surplus" means, in
relation to a Collection Period, the amount by which the total of all Prepayment
Costs (as defined below) for that Collection Period exceeds the total of all
Prepayment Benefits for that Collection Period. With respect to any Housing
Loan, a "Prepayment Benefit Shortfall" means, in relation to a Collection
Period, the amount by which the total of all Prepayment Benefits for that
Collection Period exceeds the total of all Prepayment Costs for that Collection
Period.
 
    With respect to any Housing Loan which is a Fixed Option Home Loan or
otherwise bears a fixed rate of interest (other than a Housing Loan subject to
an introductory rate of interest for 12 months or less), "Prepayment Cost"
means, on the early discharge of such Housing Loan, the amount (if any) owed by
the
 
                                       88
<PAGE>
relevant Borrower and collected by Westpac or the Servicer, in accordance with
the relevant Housing Loan agreement with respect to such early discharge. With
respect to any Housing Loan which is a Fixed Option Home Loan or otherwise bears
a fixed rate of interest (other than a Housing Loan subject to an introductory
rate of interest for 12 months or less), a "Prepayment Benefit" means, on the
early discharge of such Housing Loan, the amount (if any) credited to the
relevant Borrower's loan account by Westpac by means of a reduction in the
Housing Loan Principal of that Housing Loan, in accordance with the relevant
Housing Loan agreement.
 
    With respect to a Collection Period and any Housing Loan, "Principal Loss"
means the amount of any Liquidation Loss for that Collection Period which is
attributable to principal in relation to the relevant Housing Loan.
 
PRINCIPAL DRAWS
 
    If the Trust Manager determines on any Collection Determination Date that
the Available Income of the Trust for the Collection Period ending immediately
prior to that Collection Determination Date is insufficient to meet Total
Payments (as defined herein under "--Remaining Liquidity Shortfall") of the
Trust for that Collection Period (a "Payment Shortfall"), then Principal
Collections collected during that Collection Period will be applied to the
Payment Shortfall (a "Principal Draw") to the extent available for this purpose.
 
    Principal Draws will be reimbursed out of any Excess Available Income
available for this purpose on subsequent Payment Dates.
 
LIQUIDITY DRAWS
 
    If, on any Collection Determination Date, the Trust Manager determines that
the related Payment Shortfall, if any, will not be covered fully by a Principal
Draw, the Trust Manager must direct the Issuer Trustee to draw on the Liquidity
Facility in an amount equal to the lesser of the remaining Payment Shortfall or
the Available Liquidity Amount. Any direction by the Trust Manager to the Issuer
Trustee to draw on the Liquidity Facility is subject to there being available
funds under the Liquidity Facility.
 
REMAINING LIQUIDITY SHORTFALL
 
    If the amount available to be drawn under the Liquidity Facility is not
sufficient to satisfy the remaining Payment Shortfall in full, the amount of
such shortfall will be a "Remaining Liquidity Shortfall." If the Trust Manager
determines that a Remaining Liquidity Shortfall exists, then the Trust Manager
must reduce the Interest payable in respect of the Notes as follows:
 
        (1) first, reduce the A$ Class B Interest Amount payable to the Currency
    Swap Provider under the swap confirmation relating to the Class B Notes;
 
        (2) second, if the A$ Class B Interest Amount has been reduced to zero,
    any excess Remaining Liquidity Shortfall shall reduce pro rata, based on
    their applicable entitlements:
 
   
        (i) the A$ Class A Interest Amount payable to the Currency Swap
            Providers under the swap confirmation relating to the Class A Notes;
    
 
        (ii) the RFS Interest for all RFSs (if any);
 
       (iii) interest payable for all RFS Class A Notes (if any); and
 
        (iv) any fee payable by the Issuer Trustee under the Redraw Facility.
 
    If there is a reduction in the A$ Class B Interest Amount under (1) above,
the Interest entitlement of the Class B Noteholders shall be reduced by the same
proportion as the reduction in the A$ Class B Interest Amount. If there is a
reduction in the A$ Class A Interest Amount under (2)(i) above, the Interest
entitlement of the Class A Noteholders shall be reduced by the same proportion
as the reduction in the A$ Class A Interest Amount.
 
                                       89
<PAGE>
    With respect to any Payment Date, the "A$ Class A Interest Amount" means the
amount in A$ which is calculated:
 
        (1) on a daily basis at the applicable rate set out in the swap
    confirmation relating to the Class A Notes (being AUD- BBR-BBSW, as defined
    in the ISDA Definitions, as at the first day of the Interest Period ending
    on (but excluding) that Payment Date with a designated maturity of 90 days
    plus the spread set out in the Currency Swap);
 
        (2) on the A$ Equivalent (with respect to an amount denominated or to be
    denominated in U.S. dollars, the amount converted to (and denominated in)
    Australian dollars at the applicable exchange rate) of the aggregate of the
    Invested Amount of the Class A Notes as at the first day of the Interest
    Period ending on (but excluding) that Payment Date; and
 
        (3) on the basis of the actual number of days in that Interest Period
    and a year of 360 days.
 
    With respect to any Payment Date, the "A$ Class B Interest Amount" means,
for any Payment Date, the amount in A$ which is calculated:
 
        (1) on a daily basis at the applicable rate set out in the swap
    confirmation relating to the Class B Notes (being AUD- BBR-BBSW, as defined
    in the ISDA Definitions, as at the first day of the Interest Period ending
    on (but excluding) that Payment Date with a designated maturity of 90 days
    plus the spread);
 
        (2) on the A$ Equivalent of the aggregate of the Invested Amount of the
    Class B Notes as at the first day of the Interest Period ending on (but
    excluding) that Payment Date; and
 
        (3) on the basis of the actual number of days in that Interest Period
    and a year of 360 days.
 
    With respect to any Payment Date, "RFS Interest" means all interest on the
outstanding RFSs in respect of an Interest Period. With respect to any Payment
Date, "RFS Class A Interest" means all interest on the outstanding RFS Class A
Notes in respect of an Interest Period.
 
DISTRIBUTION OF TOTAL AVAILABLE FUNDS
 
GENERAL
 
   
    On each Payment Date, the Trust Manager shall instruct the Issuer Trustee to
apply the Total Available Funds in making the following payments in respect of
the preceding Collection Period in the following order of priority:
    
 
        (1) in relation to the first Payment Date only, the Accrued Interest
    Adjustment;
 
        (2) unpaid or unreimbursed Trust Expenses;
 
        (3) amounts payable under any Support Facility (other than the Currency
    Swap), pro rata, based on their respective entitlements, including:
 
        (i) the net amount (if any) payable by the Issuer Trustee under the
            Variable Rate Basis Swap;
 
        (ii) the net amount (if any) payable by the Issuer Trustee under each
             Fixed Rate Basis Swap; and
 
       (iii) any interest or fees payable by the Issuer Trustee under the
             Liquidity Facility,
 
          but not including amounts due under paragraph (4), (5) or (6) below;
 
        (4) repayment of any Liquidity Draw made on or prior to the previous
    Payment Date;
 
        (5) pro rata, to each of the following, based on their respective
    entitlements:
 
        (i) any interest payable on all RFSs (if any);
 
   
        (ii) the payment to the Currency Swap Providers under the swap
             confirmation relating to the Class A Notes of the A$ Class A
             Interest Amount at that date;
    
 
                                       90
<PAGE>
       (iii) the interest payable on all RFS Class A Notes (if any); and
 
        (iv) any fee payable by the Issuer Trustee under the Redraw Facility;
             and
 
   
        (6) the payment to the Currency Swap Providers under the swap
    confirmation relating to the Class B Notes of the A$ Class B Interest Amount
    as at that date.
    
 
    The sum of paragraphs (1) to (6) above represents "Total Payments" for a
Collection Period.
 
   
    The Issuer Trustee shall only make a payment described in paragraphs (1)
through (6) above to the extent that Total Available Funds remain available to
do so after each payment is made in accordance with the above priority in
accordance with the Series Notice.
    
 
TRUST EXPENSES
 
    On each Collection Determination Date the Trust Manager will determine the
following payments to be made for the relevant Collection Period (together, the
"Trust Expenses") in the following order of priority (as between themselves) on
the next Payment Date:
 
        (1) taxes payable in relation to the Trust;
 
        (2) the Issuer Trustee Fee;
 
        (3) the Trust Manager Fee;
 
        (4) any fee payable to the Security Trustee under the Security Trust
    Deed;
 
        (5) the Servicing Fee;
 
        (6) any fee payable to the Note Trustee under the Note Trust Deed;
 
        (7) any fee payable to the Agent Bank under the Agency Agreement;
 
        (8) pro rata based on their respective entitlements any costs, charges
    or expenses (other than fees) incurred by, and any liabilities owing under
    any indemnity granted to, the Security Trustee, the Servicer, the Note
    Trustee or the Agent Bank in relation to the Trust under the Transaction
    Documents, for that Collection Period; and
 
        (9) pro rata based on their respective entitlements any other costs,
    charges or expenses incurred by the Issuer Trustee or the Trust Manager in
    the administration or operation of the Trust.
 
                                       91
<PAGE>
CALCULATION OF INTEREST PAYABLE ON THE NOTES
 
    The "Interest Rate" for the Class A Notes for a particular Interest Period
is equal to USD-LIBOR-BBA on the related Interest Determination Date (as defined
herein) plus    %. The Interest Rate on the Class A Notes for the first Interest
Period will be equal to    %. The "Interest Rate" for the Class B Notes for a
particular Interest Period is equal to USD- LIBOR-BBA on the related Interest
Determination Date plus    %. The Interest Rate on the Class B Notes for the
first Interest Period will be equal to    %. See "--Calculation of
USD-LIBOR-BBA" below.
 
    With respect to any Payment Date, interest on a Class of Notes will be
calculated as the product of (a) the Invested Amount of such Class as of the
first day of that Interest Period after giving effect to any payments of
principal made with respect to such Class on such day, (b) the Interest Rate for
such Class for that Interest Period; and (c) a fraction, the numerator of which
is the actual number of days in that Interest Period and the denominator of
which is 360 days (such product, "Interest"). No Noteholder will be entitled to
payments of Interest after the related Stated Amount is reduced to zero.
 
CALCULATION OF USD-LIBOR-BBA
 
   
    On the second London banking day before the beginning of each Interest
Period (each an "Interest Determination Date"), the Agent Bank will determine
the "USD-LIBOR-BBA" as the applicable Floating Rate Option under the Definitions
of the International Swaps and Derivatives Association, Inc. ("ISDA") (the "ISDA
Definitions") being the rate applicable to any Interest Period for three-month
deposits in U.S. dollars which appears on the Telerate Page 3750 as of 11:00
A.M., London time, on the Interest Determination Date. If such rate does not
appear on the Telerate Page 3750, the rate for that Interest Period will be
determined as if the Issuer Trustee and Agent Bank had specified
"USD-LIBOR-Reference Banks" as the applicable Floating Rate Option under the
ISDA Definitions. "USD-LIBOR-Reference Banks" means that the rate for an
Interest Period will be determined on the basis of the rates at which deposits
in U.S. Dollars are offered by the Reference Banks (being four major banks in
the London interbank market) at approximately 11:00 A.M., London time, on the
Interest Determination Date to prime banks in the London interbank market for a
period of three months commencing on the first day of the Interest Period and in
a Representative Amount (as defined in the ISDA Definitions). The Agent Bank
will request the principal London office of each of the Reference Banks to
provide a quotation of its rate. If at least two such quotations are provided,
the rate for that Interest Period will be the arithmetic mean of the quotations.
If fewer than two quotations are provided as requested, the rate for that
Interest Period will be the arithmetic mean of the rates quoted by major banks
in New York City, selected by the Agent Bank, at approximately 11:00 A.M., New
York City time, on that Interest Determination Date for loans in U.S. dollars to
leading European banks for a period of three months commencing on the first day
of the Interest Period and in a Representative Amount, provided that on the
first day of the first Interest Period USD-LIBOR-BBA shall be an interpolated
rate calculated with reference to the period from (and including) the Closing
Date to (but excluding) the first Payment Date.
    
 
EXCESS AVAILABLE INCOME
 
    GENERAL
 
    On each Collection Determination Date, the Trust Manager must determine the
amount (if any) by which the Total Available Funds for the Collection Period
ending immediately prior to that Collection Determination Date exceeds the Total
Payments for that same Collection Period (such amount, the "Excess Available
Income").
 
DISTRIBUTION OF EXCESS AVAILABLE INCOME
 
    On each Collection Determination Date, the Trust Manager must apply such
Excess Available Income for the Collection Period relating to that Collection
Determination Date in the following order of priority:
 
                                       92
<PAGE>
        (1) to reimburse Principal Charge Offs for that Collection Period;
 
        (2) pro rata, based on the Stated Amount of the RFSs (if any), the
    Stated Amount of the RFS Class A Notes (if any), the Principal Outstanding
    under the Redraw Facility and the A$ Equivalent of the Stated Amount of the
    Class A Notes:
 
           (i) as a payment to the holders of the RFSs (if any) in or towards
       reinstating the Stated Amount of such RFSs, to the extent of any
       Carryover RFS Charge Offs;
 
           (ii) as a payment to the holders of the RFS Class A Notes (if any) in
       or towards reinstating the Stated Amount of such RFS Class A Notes, to
       the extent of any Carryover RFS Class A Charge Offs;
 
           (iii) as a repayment under the Redraw Facility Agreement, as a
       reduction of, and to the extent of, any Carryover Redraw Charge Offs;
 
   
           (iv) as a payment to the Currency Swap Providers under the swap
       confirmation relating to the Class A Notes, of the A$ Equivalent of any
       Carryover Class A Charge Offs; and
    
 
   
        (3) as a payment, denominated in A$, to the Currency Swap Providers
    under the swap confirmation relating to the Class B Notes of the A$
    Equivalent of any Carryover Class B Charge Offs;
    
 
        (4) to all Principal Draws which have not been repaid as at that date;
    and
 
        (5) as a distribution to any Beneficiaries (an "Excess Collections
    Distribution").
 
    All amounts to be paid pursuant to paragraphs (2), (3) and (5) will be paid
on the Payment Date immediately following the Collection Determination Date.
 
    Once distributed to a Beneficiary, an Excess Collections Distribution will
not be available to the Issuer Trustee to meet its obligations in respect of the
Trust in subsequent periods unless there has been an error in the relevant
calculation of the Excess Collections Distribution. A "Beneficiary" is any party
which holds a residual income unit in the Trust.
 
GROSS PRINCIPAL COLLECTIONS
 
    On each Collection Determination Date, the Trust Manager must determine
Gross Principal Collections for the Collection Period ending immediately prior
to that Collection Determination Date. With respect to any Collection
Determination Date, "Gross Principal Collections" are the sum of:
 
        (1) all amounts received by or on behalf of the Issuer Trustee under or
    in respect of the Housing Loans during the Collection Period in respect of
    principal, including principal prepayments;
 
        (2) all other amounts received under or in respect of the Housing Loans
    during the Collection Period in respect of principal, including:
 
           (i) amounts on account of principal recovered from the enforcement of
       a Housing Loan or Mortgage;
 
           (ii) any payments by Westpac to the Issuer Trustee on the repurchase
       of a Housing Loan in respect of principal;
 
           (iii) any amounts in the nature of principal received by or on behalf
       of the Issuer Trustee from the sale of any Trust Asset, including any
       amount received on the issue of Notes and which was not used to purchase
       a Housing Loan or Mortgage and which the Trust Manager determines is
       surplus to the requirements of the Trust;
 
           (iv) any Prepayment Costs applied towards Prepayment Benefit; and
 
           (v) any Prepayment Benefit Shortfall paid by Westpac to the Trust;
 
                                       93
<PAGE>
        (3) all amounts received by or on behalf of the Issuer Trustee during
    that Collection Period under any Support Facility (other than the Currency
    Swap) which the Trust Manager determines should be accounted for to reduce a
    Principal Loss;
 
        (4) all amounts received by or on behalf of the Issuer Trustee during
    that Collection Period:
 
           (i) from an Approved Seller or the Servicer in respect of any breach
       of a representation, warranty or undertaking contained in the Master
       Trust Deed, Series Notice or Servicing Agreement determined by the Trust
       Manager to be in respect of principal; and
 
           (ii) from an Approved Seller or the Servicer under any obligation
       under the Master Trust Deed, Series Notice or Servicing Agreement to
       indemnify, reimburse or pay damages to the Issuer Trustee for any amount
       determined by the Trust Manager to be in respect of principal;
 
        (5) any amount of Excess Available Income to be applied to meet a
    Principal Charge Off or a Carryover Charge Off;
 
        (6) any amount received by or on behalf of the Issuer Trustee during
    that Collection Period as proceeds from the issue of any RFS to the extent
    not applied to reimburse amounts drawn under the Redraw Facility;
 
        (7) any Excess Available Income to be applied to Principal Draws made on
    a previous Payment Date;
 
        (8) any Prepayment Calculation Adjustment for that Collection Period;
    and
 
   
        (9) any net amount attributable to principal received by the Trust from
    another trust established under the Master Trust Deed with respect to any
    substitution of a Housing Loan during that Collection Period ("Substitution
    Net Transfer Amount (Principal))";
    
 
but excluding a premium receivable by the Issuer Trustee on entry into a
replacement Currency Swap.
 
    On the Closing Date, the A$ Equivalent of the total Initial Invested Amount
of the Notes issued by the Issuer Trustee may exceed the Housing Loan Principal
as of the Cut-Off Date. The amount of this difference, if any, will be treated
as a Gross Principal Collection and the US$ Equivalent will be passed through to
Noteholders on the first Payment Date.
 
    With respect to any Collection Period and a Housing Loan, a "Prepayment
Calculation Adjustment" is any amount credited to the related Borrower by
Westpac to reflect an interest adjustment resulting from a change in computer
systems.
 
PRINCIPAL COLLECTIONS
 
    On each Collection Determination Date the Trust Manager must calculate
Principal Collections for the preceding Collection Period. With respect to any
Collection Determination Date, "Principal Collections" shall be equal to:
 
        (1) the Gross Principal Collections for that Collection Period; less
 
        (2) any amounts deducted by or paid to Westpac to reimburse Redraws
    funded by Westpac during that Collection Period for which Westpac has not
    been reimbursed previously.
 
DISTRIBUTION OF PRINCIPAL COLLECTIONS
 
    INITIAL PRINCIPAL DISTRIBUTIONS
 
    On each Payment Date, Principal Collections will be distributed in the
following order of priority:
 
        (1) to repay any Redraws provided by Westpac to the extent not
    previously reimbursed;
 
                                       94
<PAGE>
        (2) to repay any Principal Outstanding under the Redraw Facility;
 
        (3) to allocate to Total Available Funds any Principal Draw; and
 
        (4) to repay all amounts outstanding under each RFS Series (if any), in
    chronological order of issue, until repaid in full,
 
(together, "Initial Principal Distributions").
 
   
    Only after Initial Principal Distributions have been distributed will
Principal Collections be available to be paid to the Currency Swap Providers to
enable the Issuer Trustee to make payments to the Class A Noteholders and the
Class B Noteholders in US$ in accordance with the appropriate principal
allocation methodology set forth below. With respect to any Payment Date, "Net
Principal Collections" shall equal the amount of Principal Collections remaining
after the distribution of Initial Principal Distributions.
    
 
PAYMENTS OF PRINCIPAL ON THE NOTES
 
    With respect to any Collection Determination Date, the Trust Manager shall
determine the appropriate principal allocation methodology as set forth below.
On each Payment Date, the Trust Manager shall instruct the Issuer Trustee to pay
principal to the Noteholders in the manner and subject to the priority set forth
below.
 
SERIAL METHOD 1
 
    If, on the related Collection Determination Date, the Serial Method 1
Distribution Test has been met, then the Issuer Trustee will pay out of any Net
Principal Collections, on the immediately following Payment Date the following
amounts in the following order of priority:
 
        (1) first, pro rata, based on their respective entitlements:
 
   
           (i) as a payment, denominated in A$, to the Currency Swap Providers
       under the swap confirmation relating to the Class A Notes of an amount
       equal to the lesser of:
    
 
               (a) the Class A Forex Percentage of the sum of: (1) the Class A
           Percentage of Net Principal Collections; and (2) 50% of the Class B
           Percentage of Net Principal Collections; and
 
               (b) the A$ Equivalent of the Class A Stated Amounts for all Class
           A Notes; and
 
           (ii) as a payment denominated in A$ to the holders of the RFS Class A
       Notes (if any) of an amount equal to the lesser of:
 
               (a) the RFS Class A Forex Percentage of the sum of: (1) the Class
           A Percentage of Net Principal Collections; and (2) 50% of the Class B
           Percentage of Net Principal Collections; and
 
               (b) the RFS Class A Stated Amounts for all RFS Class A Notes (if
           any); and

<PAGE>
           (iii) the fraction, expressed as a percentage, the numerator of which
       is the Total Invested Amount on such Collection Determination Date and
       the denominator of which is the Total Initial Invested Amount, is greater
       than or equal to 10%; and
 
           (iv) the Average Quarterly Percentage on such Collection

Percentage" equals a fraction, expressed as a percentage, the numerator of which
is the aggregate Housing Loan Principal of all Housing Loans which are
Delinquent for more than 60 consecutive days as of the close of business on the
last day of that Collection Period, and the denominator of which is the
aggregate Housing Loan Principal of all Housing Loans as of the close of
business on the last day of that Collection Period. With respect to any Housing
Loan and date, "Housing Loan Principal" shall be the unpaid principal amount of
that Housing Loan on such date.
    
 
    The "Class A Forex Percentage" equals a fraction, expressed as a percentage,
the numerator of which is the A$ Equivalent of the Class A Stated Amounts at

    The "Class A Percentage" means, on a Collection Determination Date, the sum
of the aggregate of the A$ Equivalent of the Class A Stated Amounts, the RFS
Class A Stated Amounts and the Redraw Limit (as defined herein) for the
preceding Collection Determination Date as a percentage of the sum of the
aggregate of the A$ Equivalent of the Class A Stated Amounts, the RFS Class A
Stated Amounts and the Class B Stated Amounts and the Redraw Limit calculated as

Limit at that time, plus (iii) the aggregate of the RFS Stated Amounts at that
time, plus (iv) the aggregate of the RFS Class A Stated Amounts at that time.
 
APPLICATION OF PRINCIPAL CHARGE OFFS
 
    GENERAL
 
    If there is any Liquidation Loss under a Housing Loan, the Trust Manager
will direct the Servicer to make a claim under the relevant Mortgage Insurance
Policy for the aggregate amount of that Liquidation Loss if the Servicer has not
already done so. If a claim on account of a Principal Loss may not be made (or
is reduced) under the Mortgage Insurance Policy for any reason (including
because the maximum amount available under the Mortgage Pool Insurance Policy
has been exhausted, the Mortgage Insurance Policy has been terminated in respect
of that Housing Loan, the Mortgage Insurer is entitled to reduce the amount of
the claim or the Mortgage Insurer defaults in payment of a claim) then a
"Mortgage Shortfall" will arise if:
 
        (1) the total amount recovered and recoverable under the Mortgage
    Insurance Policy attributable to principal; plus
 
        (2) any damages or other amounts payable by an Approved Seller or the
    Servicer under or in respect of the Master Trust Deed, the Series Notice or
    Servicing Agreement relating to the Housing Loan which the Trust Manager
    determines to be on account of principal, is insufficient to meet the full
    amount of the Principal Loss. In that case, the aggregate amount of all
    Mortgage Shortfalls for that Collection Period (a "Principal Charge Off")
    will be applied to reduce the Stated Amounts of the Notes as described
    below.
 
    CHARGE OFFS
 
    On any Collection Determination Date, the Excess Available Income (if any)
will be applied to meet Principal Charge Offs calculated on that Collection
Determination Date for the Collection Period ending immediately prior to that
Collection Determination Date. If the amount of Excess Available Income is less
than the amount of those Principal Charge Offs, then the balance of the
Principal Charge Offs will be:
 
        (1) applied to reduce the Stated Amounts of the Class B Notes by the US$
    Equivalent of that balance (a "Class B Charge Off"), until the Class B
    Stated Amount is zero; and
 
        (2) to the extent that balance cannot be applied under paragraph (1)
    because the Class B Stated Amount is zero, applied pro rata, based on their
    respective Stated Amounts or Principal Outstanding, as applicable, to the
    reduction of the RFSs (if any) (an "RFS Charge Off"), the RFS Class A Notes
    (if any) (an "RFS Class A Charge Off") and the Class A Notes (a "Class A
    Charge Off") until the respective Stated Amounts of the Class A Notes, the
    RFSs (if any) and the RFS Class A Notes (if any) are zero and the Principal
    Outstanding under the Redraw Facility until the Principal Outstanding is
 
                                       98
<PAGE>
   
    zero (a "Redraw Facility Charge Off") (using A$ Equivalent amounts in the
    case of the Class A Notes).
    
 
    With respect to any date, the "Total Carryover Charge Off" means the sum of:
 
           (1) all Carryover Class A Charge Offs for all Class A Notes (other
       than RFS Class A Notes) as at that date;
 
           (2) all Carryover Class B Charge Offs for all Class B Notes as at
       that date;
 
           (3) the US$ Equivalent of all Carryover RFS Charge Offs for all RFSs
       as at that date; and
 
           (4) the US$ Equivalent of all Carryover RFS Class A Charge Offs for
       all RFS Class A Charge Offs as at that date.
 
REIMBURSEMENT OF CHARGE OFFS
 
    On any Collection Determination Date, if there is Excess Available Income in
respect of the Collection Period ending immediately prior to that Collection
Determination Date remaining after the reimbursement of any Principal Charge
Offs for that Collection Period, then the remaining Excess Available Income will
be used to reinstate the Stated Amounts of the Notes in the following priority:
 
        (1) first, the Carryover Redraw Charge Offs, Carryover RFS Charge Offs,
    Carryover RFS Class A Charge Offs and Carryover Class A Charge Offs, pro
    rata based on the amount of their respective Charge Offs (using A$
    Equivalent amounts in the case of Carryover Class A Charge Offs); and
 
        (2) second, the A$ Equivalent of any Carryover Class B Charge Offs.
 
    On any Collection Determination Date in relation to a Class A Note,
"Carryover Class A Charge Offs" means the aggregate of Class A Charge Offs in
relation to that Class A Note prior to that Collection Determination Date which
have not been reinstated as provided for herein. On any Collection Determination
Date in relation to a Class B Note, "Carryover Class B Charge Offs" means on any
Collection Determination Date in relation to a Class B Note, the aggregate of
Class B Charge Offs in relation to that Class B Note prior to that Collection
Determination Date which have not been reinstated as provided for herein. On any
Collection Determination Date in relation to the Redraw Facility, "Carryover
Redraw Charge Offs" means, the aggregate of Redraw Charge Offs prior to that
Collection Determination Date which have not been reinstated as provided for
herein. On any Collection Determination Date in relation to the RFSs, the
aggregate of RFS Charge Offs in relation to that RFS prior to that Collection
Determination Date which have not been reinstated as provided for herein. On any
Collection Determination Date in relation to an RFS Class A Note, "Carryover RFS
Class A Charge Offs" means the aggregate of RFS Class A Charge Offs in relation
to that RFS Class A Note prior to that Collection Determination Date which have
not been reinstated as provided for herein.
 
PAYMENTS INTO US$ ACCOUNT
 
   
    The Principal Paying Agent shall open and maintain, or cause to be opened
and maintained, an account (the "US$ Account") into which the Currency Swap
Providers shall deposit amounts denominated in US$.
    
 
   
        (1) The Issuer Trustee shall direct the Currency Swap Providers to pay
    all amounts denominated in US$ payable to the Issuer Trustee by the Currency
    Swap Providers under the Currency Swap into the US$ Account or to the
    Principal Paying Agent under the Agency Agreement on behalf of the Issuer
    Trustee.
    
 
   
        (2) If any of the Issuer Trustee, the Trust Manager or the Servicer
    receives any amount denominated in US$ from the Currency Swap Providers
    under the Currency Swap they will promptly pay that amount to the credit of
    the US$ Account.
    
 
                                       99
<PAGE>
PAYMENTS OUT OF US$ ACCOUNT
 
    The Issuer Trustee shall, or shall require that the Paying Agents shall on
its behalf, pay all amounts credited to the US$ Account or otherwise referred to
above to meet its US$ obligations under the Series Notice and the Notes, and in
accordance with the Note Trust Deed and the Agency Agreement.
 
PREPAYMENT COSTS AND PREPAYMENT BENEFITS
 
    (1) On each Collection Determination Date the Trust Manager will determine
total Prepayment Benefits and total Prepayment Costs for the relevant Collection
Period and will apply an amount equal to those total Prepayment Costs in payment
of those total Prepayment Benefits. If:
 
        (i) there is a Prepayment Cost Surplus, it will be applied under
    paragraph (2) below; and
 
        (ii) there is a Prepayment Benefit Shortfall, it will be funded under
    paragraph (3) below.
 
    (2) On each Payment Date based on calculations provided to it by the Trust
Manager, the Issuer Trustee will pay to Westpac an amount equal to the
Prepayment Cost Surplus (if any) for the Collection Period on that Payment Date
to the extent received by or on behalf of the Issuer Trustee.
 
    (3) If, on any Collection Determination Date, the Trust Manager calculates
that there is a Prepayment Benefit Shortfall, the Trust Manager must by the
close of business on that Collection Determination Date notify Westpac of the
amount of that Prepayment Benefit Shortfall. Westpac must, by 4:00 p.m. (Sydney
time) on the Remittance Date, deposit in the Collections Account for the credit
of the Issuer Trustee an amount equal to that Prepayment Benefit Shortfall. That
amount will be treated as a Gross Principal Collection.
 
DESCRIPTION OF THE REDRAW FACILITY, THE REDRAW FUNDING SECURITIES AND THE RFS
  CLASS A NOTES
 
    Certain Housing Loans in the Mortgage Pool which are charged a variable rate
of interest have the benefit of a facility which allows the borrower to draw on
repayments made by the Borrower in excess of scheduled repayments on the related
Housing Loan (any such draw, a "Redraw"). Borrowers may require Westpac to
re-advance to them previously prepaid principal. In certain circumstances,
Westpac has a contractual obligation under the related loan document to provide
the Redraw if the Borrower has made prepayments on the related Housing Loan and
such Borrower is not delinquent. A Redraw will not result in the Housing Loan
being removed from the Mortgage Pool.
 
    Westpac is entitled to be reimbursed by the Issuer Trustee for Redraws
funded by Westpac first, from Gross Principal Collections as described herein
under "--Principal Collections" herein, second, from drawings under the Redraw
Facility and third, from the proceeds of the issue of RFSs (if any), to the
extent each is available.
 
   
    If Westpac is not fully reimbursed in relation to a Redraw, it will bear the
cost of funding that Redraw until such time as it can be reimbursed by the
Issuer Trustee.
    
 
REDRAW FACILITY
 
    GENERAL
 
   
    On or prior to the Closing Date, Westpac will enter into a Redraw Facility
Agreement (the "Redraw Facility Agreement") in its capacity as "Redraw Facility
Provider" with the Issuer Trustee and Trust Manager. Pursuant to the terms of
the Redraw Facility Agreement, the Redraw Facility Provider shall be obligated,
subject to the limitations set forth below, to fund the amount of any Redraws
not funded with Gross Principal Collections. To the extent that Gross Principal
Collections are insufficient to fund Redraws (a "Redraw Shortfall") and amounts
are available under the Redraw Facility, the Trust Manager must direct the
Issuer Trustee to draw on the Redraw Facility. Under the Redraw Facility, the
Redraw Facility
    
 
                                      100
<PAGE>
Provider agrees to make advances to the Issuer Trustee up to the limit from time
to time (the "Redraw Limit") or any lesser amount as agreed between the Redraw
Facility Provider, the Issuer Trustee and the Trust Manager. At the Closing
Date, the Redraw Limit is expected to be A$      . The Redraw Limit may not be
increased without written confirmation from the Rating Agencies that the
increase would not result in a downgrading or withdrawal of the rating for the
Offered Notes then outstanding.
 
    The Redraw Facility Provider may revoke the Redraw Facility at any time
immediately on giving notice to the Issuer Trustee and the Trust Manager.
 
DRAWINGS
 
   
    In the event of a Redraw Shortfall on any Collection Determination Date, the
Trust Manager must direct the Issuer Trustee to draw down on the Redraw Facility
for an amount (a "Redraw Advance") equal to the lesser of the Redraw Shortfall
and the Available Redraw Amount (as defined herein). A drawing may only be made
under the Redraw Facility on account of a Redraw Shortfall.
    
 
   
    "Available Redraw Amount" means at any time the greater of: (a) the Redraw
Limit at such time less (i) the Principal Outstanding at that time; and (ii) the
Carryover Redraw Charge Offs at that time; and (b) zero. The sum of all Redraw
Advances outstanding on any particular date less the Carryover Redraw Charge
Offs at that time shall be the "Principal Outstanding."
    
 
   
    A drawing may only be made by the Issuer Trustee giving to the Redraw
Facility Provider a duly completed drawdown notice signed by the Issuer Trustee;
provided, however, that each of the following conditions precedent to drawing
are met.
    
 
CONDITIONS PRECEDENT TO DRAWING
 
    The obligations of the Redraw Facility Provider to make available each
Redraw Advance are subject to the conditions precedent that:
 
    (1) no event of default has occurred and is continuing under the Redraw
Facility at the date of the relevant drawdown notice and the relevant drawdown
date or will result from the provision of the Redraw Advance; and
 
    (2) the representations and warranties by the Issuer Trustee in the Redraw
Facility are true as at the date of the relevant drawdown notice and the
relevant drawdown date as though they had been made at that date in respect of
the facts and circumstances then subsisting.
 
DRAW FEE
 
   
    With respect to any Redraw Advance made by the Redraw Facility Provider, a
fee (the "Draw Fee") will accrue from day to day on the amount of each such
Redraw Advance from the date of its advance at a rate equal to the Bank Bill
Rate plus a margin (which varies depending on how long the Redraw Advance is
outstanding), calculated on the basis of the actual number of days elapsed since
the advance and a year of 365 days. The Draw Fee shall be payable on each
Payment Date and on termination of the Redraw Facility. To the extent any Draw
Fee is not paid, the amount of such unpaid Draw Fee will be capitalized and
interest will accrue on any such unpaid Draw Fee. On any date, the "Bank Bill
Rate" shall be the rate calculated by taking the rates quoted on the Reuters
Screen BBSW Page at approximately 10:00 am, Sydney time, on that date for each
Reference Bank so quoting (but not fewer than five) as being the mean buying and
selling rate for a bill (which for the purpose of this definition means a bill
of exchange of the type specified for the purpose of quoting on the Reuters
Screen BBSW Page) having a tenor of 90 days eliminating the highest and lowest
mean rates and taking the average of the remaining mean rates and then (if
necessary) rounding the resultant figure upwards to four decimal places. If on
any date fewer than five Reference Banks have quoted rates on the Reuters Screen
BBSW Page, the rate for that date shall be calculated as above by taking the
rates otherwise quoted by five of the Reference Banks on application by
    
 
                                      101
<PAGE>
the parties for such a bill of the same tenor. If in respect of any date the
rate for that date cannot be determined in accordance with the foregoing
procedures then the rate for that date shall mean such rate as is agreed between
the Trust Manager and Westpac having regard to comparable indices then
available, provided that on the first day of any first Interest Period as it
relates to a Class of Notes the Bank Bill Rate shall be an interpolated rate
calculated with reference to the tenor of the relevant period.
 
AVAILABILITY FEE
 
   
    For so long as the Redraw Facility exists, a fee (the "Availability Fee")
shall accrue daily from the date of the Redraw Facility on the Available Redraw
Amount, which Availability Fee is payable on each Payment Date and on
termination of the Redraw Facility. The Availability Fee is calculated on the
actual number of days elapsed and a year of 365 days.
    
 
REPAYMENT OF REDRAW ADVANCES
 
    To the extent a Redraw Advance has been made and has not been repaid to the
Redraw Facility Provider, the amount of such unreimbursed Redraw Advance is
repayable on the following Payment Date and on termination of the Redraw
Facility, to the extent that there are funds available for such payment. It is
not an event of default if the Issuer Trustee does not have funds available to
repay the full amount of the unreimbursed Redraw Advance on the following
Payment Date.
 
EVENTS OF DEFAULT UNDER THE REDRAW FACILITY
 
    It is an event of default under the Redraw Facility (whether or not such
event is within the control of the Issuer Trustee) if:
 
   
        (1) an amount is available for payment to the Redraw Facility Provider
    under the Redraw Facility, and the Issuer Trustee does not pay that amount
    within 10 Business Days of its due date;
    
 
        (2) an Insolvency Event occurs in relation to the Trust;
 
        (3) an Insolvency Event occurs in relation to the Issuer Trustee, and a
    successor trustee of the Trust is not appointed within 30 days of that
    Insolvency Event;
 
        (4) the Termination Date occurs in relation to the Trust; or
 
        (5) an event of default (as defined in the Security Trust Deed) occurs
    and any action is taken to enforce the security interest under the Security
    Trust Deed over the assets of the Trust (including appointing a receiver or
    receiver and manager or selling any of those assets).
 
   
    With respect to the Issuer Trustee (in its personal capacity and as trustee
of a Trust), the Trust Manager, a Servicer, Westpac or a Mortgage Insurer (each
a "relevant corporation"), an "Insolvency Event" will occur upon the happening
of any of the following events:
    
 
        (1) an administrator of the relevant corporation is appointed;
 
        (2) except for the purpose of a solvent reconstruction or amalgamation:
 
           (i) an application or an order is made, proceedings are commenced, a
       resolution is passed or proposed in a notice of proceedings or an
       application to a court or other steps (other than frivolous or vexatious
       applications, proceedings, notices and steps) are taken for:
 
   
               (a) the winding up, dissolution or administration of the relevant
           corporation; or
    
 
                                      102
<PAGE>
        (b) the relevant corporation entering into an arrangement, compromise or
    composition with or assignment for the benefit of its creditors or a class
    of them; or
 
        (ii) the relevant corporation ceases, suspends or threatens to cease or
    suspend the conduct of all or substantially all of its business or disposes
    of or threatens to dispose of substantially all of its assets; or
 
    (3) the relevant corporation is, or under applicable legislation is taken to
be, unable to pay its debts (other than as the result of a failure to pay a debt
or claim the subject of a good faith dispute) or stops or suspends or threatens
to stop or suspend payment of all or a class of its debts (except, in the case
of the Issuer Trustee where this occurs in relation to another trust of which it
is the trustee);
 
    (4) a receiver, receiver and manager or administrator is appointed (by the
relevant corporation or by any other person) to all or substantially all of the
assets and undertaking of the relevant corporation or any part thereof (except,
in the case of the Issuer Trustee where this occurs in relation to another trust
of which it is the trustee); or
 
    (5) anything analogous to an event referred to in paragraphs (1) to (5)
(inclusive) or having substantially similar effect, occurs with respect to the
relevant corporation.
 
   
    The "Termination Date" with respect to the Trust shall be the earlier to
occur of:
    
 
    (1) the date which is 80 years after the date of creation of the Trust;
 
    (2) the termination of the Trust under statute or general law;
 
    (3) full and final enforcement of the Security Trust Deed; or
 
   
    (4) at any time after all creditors of the Trust have been repaid in full
and the Issuer Trustee and the Trust Manager agree that no further Notes are
proposed to be issued by the Issuer Trustee in relation to the Trust, the
Business Day immediately following that date.
    
 
CONSEQUENCES OF OCCURRENCE OF EVENTS OF DEFAULT
 
    At any time after an event of default (whether or not it is continuing) the
Redraw Facility Provider may do all or any of the following:
 
   
    (1) by notice to the Issuer Trustee and the Trust Manager declare all moneys
actually or contingently owing under the Redraw Facility immediately due and
payable, and the Issuer Trustee must immediately pay the Principal Outstanding
together with accrued interest and fees and all such other moneys; and
    
 
    (2) by notice to the Issuer Trustee and the Trust Manager cancel the Redraw
Limit with effect from any date specified in that notice.
 
TERMINATION OF THE REDRAW FACILITY
 
    The Redraw Facility will terminate on the earliest of the following:
 
    (1) the date on which the Issuer Trustee enters into a replacement Redraw
Facility;
 
   
    (2) one month after the Class A Notes, the Class B Notes, the RFSs and the
Class A RFS Notes have been redeemed in full in accordance with the Master Trust
Deed and the Series Notice;
    
 
    (3) following an event of default under the Redraw Facility, the date on
which the Redraw Facility Provider declares the Redraw Facility terminated;
 
   
    (4) the date on which the Issuer Trustee has cancelled the Redraw Limit in
full. (The Issuer Trustee may cancel all or part of the Redraw Limit on not less
than five Business Days irrevocable notice to the Redraw Facility Provider);
    
 
                                      103
<PAGE>
   
    (5) the date which is one year after the Maturity Date;
    
 
   
    (6) the date on which the Redraw Limit is cancelled in full by the Redraw
Facility Provider; or
    
 
    (7) the date on which Westpac Securitisation Management Pty Limited retires
or is removed as Trust Manager under the Master Trust Deed.
 
   
    The Redraw Limit may be also be reduced in part by the Redraw Facility
Provider by giving notice to the Issuer Trustee and the Trust Manager. Such a
reduction does not result in a termination of the Redraw Facility.
    
 
ISSUANCE OF REDRAW FUNDING SECURITIES ("RFS")
 
    If on a Collection Determination Date:
 
    (1) Gross Principal Collections for the Collection Period preceding that
Collection Determination Date and all amounts available to be drawn under the
Redraw Facility are insufficient to fund Redraws made during that Collection
Period; or
 
    (2) the Principal Outstanding under the Redraw Facility divided by the
Redraw Limit, expressed as a percentage, is equal to or greater than 90% of the
Redraw Limit;
 
    then the Trust Manager may give the Issuer Trustee a direction to issue a
series of RFSs (the "RFS Series").
 
CONDITION PRECEDENT TO THE ISSUE OF RFSS
 
    Notwithstanding the requirements referred to above, before giving a
direction for the issue of an RFS Series the Trust Manager must confirm with the
Rating Agencies that the issue will not result in the downgrading or withdrawal
of the rating of any Offered Note.
 
RFS CLASS A NOTES
 
    If, on the fifth Collection Determination Date following the date on which
an RFS Series was issued, the RFS Stated Amount for all RFSs in that RFS Series
has not been reduced to zero, each of those outstanding RFSs will convert to an
"RFS Class A Note." The converted RFS will:
 
    (1) have an Initial Invested Amount equal to the RFS Initial Invested Amount
of that Note when it was an RFS;
 
    (2) have an Invested Amount equal to the RFS Invested Amount of that Note
when it was an RFS at the date of conversion;
 
    (3) have a Stated Amount equal to the RFS Stated Amount of that Note when it
was an RFS at the date of conversion;
 
    (4) be denominated in Australian dollars;
 
    (5) receive all payments of principal and interest denominated in Australian
dollars;
 
    (6) have an Interest Rate calculated by reference to the Bank Bill Rate, not
"USD-LIBOR-BBA";
 
   
    (7) be evidenced by a notation in a register maintained by the Issuer
Trustee; and
    
 
    (8) have a Margin equal to the margin under the Class A Notes.
 
    "Margin" means: (1) in the case of Class A Notes,    % and in the case of
the Class B Notes,    %; (2) in the case of any RFSs, the margin inscribed in
the register maintained by the Issuer Trustee in relation to those RFSs on their
issue date; and (3) in the case of any RFS Class A Note, the Margin for the
Class A Notes plus the spread under the Currency Swap.
 
                                      104
<PAGE>
FORM OF THE RFSS AND THE RFS CLASS A NOTES
 
   
    The RFSs and the RFS Class A Notes will be evidenced by a notation in a
register maintained by the Issuer Trustee and denominated in Australian dollars
which will be issued in Australia to Australian resident investors only. The
total issue amount of RFS Class A Notes (if any) will be determined by the
amount of RFSs (if any) issued during the term of the Offered Notes. The RFSs
and RFS Class A Notes are not offered hereby.
    
 
INTEREST PAYABLE ON THE RFSS AND THE RFS CLASS A NOTES
 
    Commencing on the issue date of an RFS or the conversion date of an RFS
Class A Note, Interest is payable monthly in arrears on each RFS and RFS Class A
Note to the person whose name is registered under the Master Trust Deed and the
Series Notice as the holder of the RFS or RFS Class A Note, until the Maturity
Date or until the Stated Amount of the RFS or RFS Class A Note is reduced to
zero (whichever is earlier). "Interest", with respect to an RFS or an RFS Class
A Note, shall be equal to the interest accrued on the Invested Amount for such
RFS or RFS Class A Note at a rate equal to the Bank Bill Rate on the first day
of that Interest Period plus the margin for the RFS or RFS Class A Note, during
the period from the subsequent Payment Date to the day preceding the Payment
Date, calculated on the actual number of days in the related Interest Period
over 365. With respect to any RFS and Payment Date, the margin shall be a per
annum rate specified by the Trust Manager to the Issuer Trustee as applying to
that RFS on its issue date as inscribed in the register for that RFS. With
respect to any RFS Class A Note and a Payment Date, the related margin will be
the Margin applicable to Class A Notes for the same Interest Period (as defined
in the Currency Swap).
 
    Payments to the holders of RFSs and the holders of RFS Class A Notes will be
in Australian dollars. Payments of Interest on the RFSs and the RFS Class A
Notes are PARI PASSU with respect to Interest payable on the Class A Notes and
rank ahead of Interest payable on the Class B Notes.
 
   
SUBORDINATION OF CLASS B NOTES; PRIORITY OF PAYMENT OF PRINCIPAL TO RFS
    
 
    The Class A Noteholders, the holders of RFSs (if any), the holders of RFS
Class A Notes (if any) and the Redraw Facility Provider will have the benefit of
the subordination of the Class B Notes. That is, to the extent that there is a
loss on a Housing Loan which is not satisfied by a claim (or deemed claim) under
a Mortgage Insurance Policy, by amounts recoverable by the Issuer Trustee from
an Approved Seller or the Servicer, or by the application of Excess Available
Income, the amount of that loss will be allocated to the Class B Notes, reducing
the Stated Amount of the Class B Notes until their Stated Amount is zero. The
amount of any remaining loss will then be allocated PARI PASSU, between the
Class A Notes, the RFSs (if any), the RFS Class A Notes (if any) and the Redraw
Facility, reducing the Stated Amount of the Class A Notes, the RFSs (if any) and
the RFS Class A Notes (if any) until their Stated Amount is zero and reducing
the Principal Outstanding under the Redraw Facility until it is zero. For
further details see "-- Application of Principal Charge Offs" above. Payments of
principal on the RFSs will be made prior to payments of principal to the Offered
Noteholders and the holders of the RFS Class A Notes.
 
SUBSTITUTION OF HOUSING LOANS
 
    The Trust Manager may substitute a housing loan from a WST warehouse trust
for a Housing Loan in the Trust. For a housing loan in a WST trust to be
eligible for substitution for a Housing Loan, the housing loan in the other WST
trust must have a maturity date not later than the date which is one year before
the Maturity Date of the Notes, have similar product features to one or more of
the Housing Loans, have an Unpaid Balance within A$30,000 of the Unpaid Balance
of the Housing Loan for which it is being substituted and must otherwise be
suitable for substitution in the Trust Manager's sole and absolute discretion.
The Trust Manager may take into account the geographic locations of the
properties securing the Housing Loan and the substituted housing loan. The Trust
Manager may not substitute a housing loan
 
                                      105
<PAGE>
unless it has received written confirmation from the Rating Agencies that the
substitution will not result in the downgrade or withdrawal of the rating given
to the Offered Notes. In addition, if the Unpaid Balance of the Housing Loan
removed from the Trust is greater than the Unpaid Balance of the substituted
housing loan, the WST warehouse trust must pay the Issuer Trustee such
difference, and, on the following Payment Date, any relevant interest
adjustment.
 
   
PRESCRIPTION
    
 
   
    An Offered Note shall become void in its entirety unless surrendered for
payment within ten years of the Relevant Date in respect of any payment thereon
the effect of which would be to reduce the Stated Amount of such Note to zero.
After the date on which a Note becomes void in its entirety, no claim may be
made in respect of it.
    
 
    The "Relevant Date" means the date on which a payment first becomes due but,
if the full amount of the money payable has not been received in New York City
by the Principal Paying Agent or the Note Trustee on or prior to that date, it
means the date on which, the full amount of such money having been so received,
notice to that effect is duly given in accordance with the terms of the Notes.
 
CLEAN-UP OFFER
 
    If at any time the aggregate Housing Loan Principal, expressed as a
percentage of the aggregate Housing Loan Principal as of the Cut-Off Date, is
less than 10%, then, if instructed by the Trust Manager, the Seller Trustee may
repurchase, on the following Payment Date, the equitable title to the Housing
Loans held by the Trust for an amount equal to the Unpaid Balance (in the case
of performing Housing Loans) or the Fair Market Value (in the case of
non-performing Housing Loans). The proceeds of sale will be applied by the
Issuer Trustee to repay moneys owing to Noteholders at that time in accordance
with the priorities for applying payments of Interest and principal between the
Classes of Notes.
 
REDEMPTION OF THE NOTES
 
    If an event of default occurs under the Security Trust Deed while the Notes
are outstanding, the Security Trustee may (subject, in certain circumstances, to
the prior written consent of the Note Trustee in accordance with the provisions
of the Security Trust Deed), (and will if so directed by the Note Trustee alone
where it is the only Voting Mortgagee, or, otherwise by a resolution of 75% of
the Voting Mortgagees) enforce the security created by the Security Trust Deed.
That enforcement can include the sale of some or all of the Housing Loans. There
is no guarantee that the Security Trustee will be able to sell the Housing Loans
for their then Unpaid Balance. Accordingly, the Security Trustee may not be able
to realize the full value of the Housing Loans and this may have an impact upon
the Issuer Trustee's ability to repay all amounts outstanding in relation to the
Notes.
 
    Any proceeds from the enforcement of the security will be applied in
accordance with the order of priority of payments as set out in the Security
Trust Deed. See "SECURITY FOR THE NOTES-- Priorities Under the Security Trust
Deed."
 
    If the Trust terminates while Notes are outstanding, Westpac has a right of
first refusal to acquire the Housing Loans. The price to be paid by Westpac for
performing and non-performing Housing Loans must not be less than their Fair
Market Value. In the case of performing loans, the Issuer Trustee is required to
offer to sell them to Westpac under its right of first refusal for their then
Unpaid Balance. The "Unpaid Balance" of a Housing Loan, means the sum of (a) the
unpaid principal amount of that Housing Loan; and (b) the unpaid amount of all
finance charges, interest payments and other amounts accrued on or payable under
or in connection with that Housing Loan or the related Mortgage or other rights
relating to the Housing Loan. Where the Fair Market Value of a Housing Loan is
less than its then Unpaid Balance, its acquisition by Westpac will be subject to
prior approval by an Extraordinary Resolution of Noteholders. This is because in
such circumstances there may be a shortfall in the amount available to the
Issuer Trustee
 
                                      106
<PAGE>
to fully repay all amounts outstanding in relation to the Notes. The Servicer
will determine whether a Housing Loan is performing or non-performing.
 
   
WITHHOLDING OR TAX DEDUCTIONS
    
 
   
    All payments in respect of the Offered Notes will be made without
withholding or tax deduction for, or on account of, any present or future taxes,
duties or charges of whatsoever nature unless the Issuer Trustee or any Paying
Agent is required by applicable law to make any such payment in respect of the
Offered Notes subject to any withholding or deduction for, or on account of, any
present or future taxes, duties or charges of whatsoever nature. In the event
that the Issuer Trustee or that the Paying Agent (as the case may be) shall make
such payment after such withholding or deduction has been made, it shall account
to the relevant authorities for the amount so required to be withheld or
deducted. Neither the Issuer Trustee nor any Paying Agent will be obliged to
make any additional payments to holders of the Offered Notes in respect to that
withholding or deduction.
    
 
   
REDEMPTION OF THE OFFERED NOTES FOR TAXATION OR OTHER REASONS
    
 
   
    If the Trust Manager satisfies the Issuer Trustee and the Note Trustee
immediately prior to giving the notice referred to below that either (i) on the
next Payment Date the Issuer Trustee would be required to deduct or withhold
from any payment of principal or interest in respect of the Offered Notes any
amount for or on account of any present or future taxes, duties, assessments or
governmental charges of whatever nature imposed, levied, collected, withheld or
assessed by the Commonwealth of Australia or any of its political sub-divisions
or any of its authorities or (ii) the total amount payable in respect of
interest in relation to the Housing Loans for a Collection Period ceases to be
receivable (whether or not actually received) by the Issuer Trustee during such
Collection Period, the Issuer Trustee must, when so directed by the Trust
Manager (at the Trust Manager's option) (provided that the Issuer Trustee will
be in a position on such Payment Date to discharge (and will so certify to the
Issuer Trustee and the Note Trustee) all its liabilities in respect of such
Class and any amounts required under the Security Trust Deed to be paid in
priority to or pari passu with such Class), at any time at its option, having
given not more than 60 nor less than 30 days' notice to the Noteholders of such
Class redeem all, but not some, of such Class at their Invested Amount (or at
the option of the Noteholders of such Class, to be exercised by way of
Extraordinary Resolution of the Noteholders of such Class, at their Stated
Amount), together with accrued interest to the date of redemption on any
subsequent Payment Date, provided that the Noteholders of such Class may by
Extraordinary Resolution elect, and shall notify the Issuer Trustee and the
Trust Manager, that they do not require the Issuer Trustee to redeem such Class
of Notes in the circumstances described above.

    The Trust will terminate on any date which is a Termination Date.
 
REALIZATION UPON TRUST ASSETS
 
    On the termination of the Trust, subject to Westpac's right of first refusal
outlined below, the Issuer Trustee must sell and realize the assets of the Trust
within 180 days. During the 180 day period, the Housing Loans, if performing,
must not be sold for less than their Unpaid Balance and in the case of non-
performing Housing Loans, for less than their Fair Market Value. The Issuer
Trustee may not sell any performing Housing Loan, within the 180 day period, for
less than its Fair Market Value without the consent of an Extraordinary
Resolution of the relevant Noteholders. The Servicer will determine whether a
Housing Loan is performing or non-performing.
 
                                      107

APPROVED SELLER'S RIGHT OF FIRST REFUSAL
 
    As soon as practical after the Termination Date of the Trust, the Trust
Manager will direct the Issuer Trustee to offer (by written notice to Westpac)
irrevocably to extinguish in favor of Westpac, or if the Issuer Trustee has
perfected its title, to equitably assign to Westpac, its entire right, title and
interest in and to the Housing Loans, and related Mortgages (if any) for their
Unpaid Balance (for performing Housing Loans) and their Fair Market Value (for
non-performing Housing Loans). If the Fair Market Value of a Housing Loan is
less than its Unpaid Balance, the sale requires the approval of an Extraordinary
Resolution of Noteholders.
 
    The Issuer Trustee is not entitled to sell any Housing Loans unless Westpac
has failed to accept the offer within 180 days after the occurrence of the
Termination Date by paying to the Issuer Trustee, within 180 days, the purchase
price.
 
DISTRIBUTION
 
    After deducting expenses, the Trust Manager shall direct the Issuer Trustee
to distribute the proceeds of realization of the assets of the Trust in
accordance with the cashflow allocation methodology set out above, and in
accordance with any directions given to it by the Trust Manager.
 
    If all Notes relating to the Trust have been fully redeemed and the Trust's
creditors paid in full, the Issuer Trustee may distribute all or part of the
Trust Assets to the relevant Beneficiary.
 
TRUST ACCOUNTS
 
    The Issuer Trustee will establish and maintain under the Master Trust Deed
bank accounts with an Approved Bank, consisting of the "Collection Account" and
the US$ Account (collectively, the "Trust Accounts"). Each bank account shall be
opened by the Issuer Trustee in its name and in its capacity as trustee of the
Trust. No bank account shall be used for any purpose other than for the Trust
and in accordance with the Master Trust Deed.
 
   
    The Trust Manager shall have the discretion and the duty to recommend or to
propose in writing to the Issuer Trustee, the manner in which any moneys forming
part of the Trust shall be invested in Authorized Investments and what
purchases, sales, transfers, exchanges, collections, realizations or alterations
of Trust Assets shall be effected and when and how the same should be effected.
It is the role of the Issuer Trustee to give effect to all such recommendations
or proposals of the Trust Manager. Each investment of moneys on deposit in the
Trust Accounts shall be in Authorized Investments that will mature not later
than the Business Day preceding the applicable monthly Payment Date. "Authorized
Investments" consist of the following: (a) Housing Loans, Mortgages and other
related securities, (b) cash, (c) bonds, debentures, stock or treasury bills of
the Commonwealth of Australia or the Government of any State or Territory of the
Commonwealth; (d) debentures or stock of any public statutory body constituted
under the law of the Commonwealth of Australia or of any State of the
Commonwealth where the repayment of the principal is secured and the interest
payable thereon is guaranteed by the Commonwealth or any State or Territory of
the Commonwealth; (e) notes of other securities of the Commonwealth of Australia
or the Government of any State or Territory of the Commonwealth; (f) (i)
deposits with, or the acquisition of certificates of deposit (whether
negotiable, convertible or otherwise), issued by, a bank which carries on
business in Victoria and New South Wales; (ii) bills of exchange which at the
time of acquisition have a remaining term to maturity of not more than 200 days,
accepted or endorsed by a bank which carries on business in Victoria and New
South Wales, which, in each case, has either: (A) the highest short-term rating
available to be given by the Rating Agencies; or (B) if such investment has a
maturity of 30 days or less and does not exceed 20% of the total Invested Amount
of all relevant Notes on the date of the investment, a short-term rating of
A-1/P-1/F-1 by the Rating Agencies; and (g) any other assets of a class of
assets that are both: (i) prescribed for the purposes of sub-paragraph (iv) of
the definition of a "pool of mortgages" in section 84FA(1) of the Stamp Duties
Act, 1920 of New South Wales, or are otherwise
    
 
                                      108
<PAGE>
included within that definition of "pool of mortgages"; and (ii) declared by
order of the Governor in Council of Victoria and published in the Victorian
Government Gazette to be assets for purposes of Subdivision 17A of the Stamps
Act, 1958 of Victoria or are otherwise included within sub-paragraph (b)(ii) of
the definition of "pool of mortgages" in section 137NA of that Act.
 
GENERAL

allocated by the Trust Manager, and paid by the Issuer Trustee as directed by
the Trust Manager, as set forth herein.

    Agent Bank; and
 
     (xxxiv) all other calculations necessary for the Issuer Trustee to make
    allocations and distributions to Noteholders.
 
    The Notes will be registered in the name of a nominee of DTC and will not be
registered in the names of the beneficial owners or their nominees. As a result,
unless and until Definitive Notes are issued in the limited circumstances
described under "--Definitive Notes" below, beneficial owners will not be
recognized by the Issuer Trustee as Noteholders, as that term is used in the
Master Trust Deed. Hence, until such time, beneficial owners will receive
reports and other information provided for under the Transaction Documents only
if, when and to the extent provided by DTC and its participating organizations.
 
BOOK-ENTRY REGISTRATION
 
    Each Class of Notes will be represented by one or more book-entry Notes (the
"Book-Entry Notes"). Persons acquiring beneficial ownership interests in the
Notes ("Note Owners") will hold their Notes through the Depository Trust Company
("DTC") in the United States, or Cedel or Euroclear (in Europe) if they are
participants of such systems, or indirectly through organizations which are
participants in such systems. The Book-Entry Notes will be issued in one or more
certificates which equal the aggregate principal balance of each Class of Notes
and will initially be registered in the name of Cede & Co., the nominee of DTC.
Cedel and Euroclear will hold omnibus positions on behalf of their participants
through customers' securities accounts in Cedel's and Euroclear's names on the
books of their respective depositaries which in turn will hold such positions in
customers' securities accounts in the depositaries' names on the books of DTC.
Citibank will act as depositary for Cedel, and Chase will act as depositary for
Euroclear (in such capacities, individually, the "Relevant Depositary" and
collectively, the "European Depositaries"). Investors may hold such beneficial
interests in the Book-Entry Notes in minimum denominations of US$100,000. Except
as described below, no person acquiring a Book-Entry Note (each, a "beneficial
owner") will be entitled to receive a physical certificate representing such
Note (a "Definitive Note"). Unless and until Definitive Notes are issued, it is
anticipated that the only "Noteholder" of each Class of Notes will be Cede &
Co., as nominee of DTC. Note Owners will not be Noteholders as that term is used
in the Master Trust Deed. Note Owners are only permitted to exercise their
rights indirectly through Participants and DTC.
 
    The beneficial owner's ownership of a Book-Entry Note will be recorded on
the records of the brokerage firm, bank, thrift institution or other financial
intermediary (each, a "Financial Intermediary")
 
                                      110
<PAGE>
that maintains the beneficial owner's account for such purpose. In turn, the
Financial Intermediary's ownership of such Book-Entry Note will be recorded on
the records of DTC (or of a participating firm that acts as agent for the
Financial Intermediary, whose interest will in turn be recorded on the records
of DTC, if the beneficial owner's Financial Intermediary is not a DTC
participant and on the records of Cedel or Euroclear, as appropriate).
 
    Note Owners will receive all distributions of principal of, and interest on,
each Class of Notes from the Trustee through DTC and DTC participants. While the
Notes are outstanding (except under the circumstances described below), under
the rules, regulations and procedures creating and affecting DTC and its
operations (the "Rules"), DTC is required to make book-entry transfers among
Participants on whose behalf it acts with respect to the Notes and is required
to receive and transmit distributions of principal of, and interest on, the
Notes. Participants and indirect participants with whom Note Owners have
accounts with respect to Notes are similarly required to make book-entry
transfers and receive and transmit such distributions on behalf of their
respective Note Owners. Accordingly, although Note Owners will not possess
certificates, the Rules provide a mechanism by which Note Owners will receive
distributions and will be able to transfer their interest.
 
    Note Owners will not receive or be entitled to receive certificates
representing their respective interests in the Offered Notes, except under the
limited circumstances described below. Unless and until Definitive Notes are
issued, Note Owners who are not Participants may transfer ownership of Notes
only through Participants and indirect participants by instructing such
Participants and indirect participants to transfer Notes, by book-entry
transfer, through DTC for the account of the purchasers of such Offered Notes,
which account is maintained with their respective Participants. Under the Rules
and in accordance with DTC's normal procedures, transfers of ownership of Notes
will be executed through DTC and the accounts of the respective Participants at
DTC will be debited and credited. Similarly, the Participants and indirect
participants will make debits or credits, as the case may be, on their records
on behalf of the selling and purchasing Note Owners.
 
    Because of time zone differences, credits of securities received in Cedel or
Euroclear as a result of a transaction with a Participant will be made during
subsequent securities settlement processing and dated the Business Day following
the DTC settlement date. Such credits or any transactions in such securities
settled during such processing will be reported to the relevant Euroclear or
Cedel Participants on such Business Day. Cash received in Cedel or Euroclear as
a result of sales of securities by or through a Cedel Participant (as defined
below) or Euroclear Participant (as defined below) to a DTC Participant will be
received with value on the DTC settlement date but will be available in the
relevant Cedel or Euroclear cash account only as of the Business Day following
settlement in DTC. For information with respect to tax documentation procedures
relating to the Notes, [see "UNITED STATES FEDERAL INCOME TAX
CONSEQUENCES--Federal Income Tax Consequences to Foreign Investors" and
"--Backup Withholding" herein and "GLOBAL CLEARANCE, SETTLEMENT AND TAX
DOCUMENTATION PROCEDURES--Certain U.S. Federal Income Tax Documentation
Requirements" in Annex I hereto.]
 
    Transfers between Participants will occur in accordance with DTC rules.
Transfers between Cedel Participants and Euroclear Participants will occur in
accordance with their respective rules and operating procedures.
 
    Cross-market transfers between persons holding directly or indirectly
through DTC, on the one hand, and directly or indirectly through Cedel
Participants or Euroclear Participants, on the other, will be effected in DTC in
accordance with DTC rules on behalf of the relevant European international
clearing system by the Relevant Depositary; however, such cross market
transactions will require delivery of instructions to the relevant European
international clearing system by the counterparty in such system in accordance
with its rules and procedures and within its established deadlines (European
time). The relevant European international clearing system will, if the
transaction meets its settlement requirements, deliver instructions to the
Relevant Depositary to take action to effect final settlement on its behalf by
 
                                      111
<PAGE>
delivering or receiving securities in DTC, and making or receiving payment in
accordance with normal procedures for same day funds settlement applicable to
DTC. Cedel Participants and Euroclear Participants may not deliver instructions
directly to the European Depositaries.
 
    DTC, which is a New York-chartered limited purpose trust company, performs
services for its participants, some of which (and/or their representatives) own
DTC. In accordance with its normal procedures, DTC is expected to record the
positions held by each DTC participant in the Book-Entry Notes, whether held for
its own account or as a nominee for another person. In general, beneficial
ownership of Book-Entry Notes will be subject to the rules, regulations and
procedures governing DTC and DTC participants as in effect from time to time.
 
    Cedel is incorporated under the laws of Luxembourg as a professional
depository. Cedel holds securities for its participating organizations ("Cedel
Participants") and facilitates the clearance and settlement of securities
transactions between Cedel Participants through electronic book-entry changes in
accounts of Cedel Participants, thereby eliminating the need for physical
movement of certificates. Transactions may be settled in Cedel in any of 28
currencies, including United States dollars. Cedel provides to its Cedel
Participants, among other things, services for safekeeping, administration,
clearance and settlement of internationally-traded securities and securities
lending and borrowing. Cedel interfaces with domestic markets in several
countries. As a professional depository, Cedel is subject to regulation by the
Luxembourg Monetary Institute. Cedel participants are recognized financial
institutions around the world, including underwriters, securities brokers and
dealers, banks, trust companies, clearing corporations and certain other
organizations. Indirect access to Cedel is also available to others, such as
banks, brokers, dealers and trust companies that clear through or maintain a
custodial relationship with a Cedel Participant, either directly or indirectly.
 
    Euroclear was created in 1968 to hold securities for its participants
("Euroclear Participants") and to clear and settle transactions between
Euroclear Participants through simultaneous electronic book-entry delivery
against payment, thereby eliminating the need for physical movement of
certificates and any risk from lack of simultaneous transfers of securities and
cash. Transactions may be settled in any of 32 currencies, including United
States dollars. Euroclear includes various other services, including securities
lending and borrowing and interfaces with domestic markets in several countries
generally similar to the arrangements for cross-market transfers with DTC
described above. Euroclear is operated by the Brussels, Belgium office of Morgan
Guaranty Trust Company of New York (the "Euroclear Operator"), under contract
with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the
"Cooperative"). All operations are conducted by the Euroclear Operator, and all
Euroclear securities clearance accounts and Euroclear cash accounts are accounts
with the Euroclear Operator, not the Cooperative. The Cooperative establishes
policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants
include banks (including central banks), securities brokers and dealers and
other professional financial intermediaries. Indirect access to Euroclear is
also available to other firms that clear through or maintain a custodial
relationship with a Euroclear Participant, either directly or indirectly.
 
    The Euroclear Operator is the Belgian branch of a New York banking
corporation which is a member bank of the Federal Reserve System. As such, it is
regulated and examined by the Board of Governors of the Federal Reserve System
and the New York State Banking Department, as well as the Belgian Banking
Commission.
 
    Securities clearance accounts and cash accounts with the Euroclear Operator
are governed by the Terms and Conditions Governing Use of Euroclear and the
related Operating Procedures of the Euroclear System and applicable Belgian law
(collectively, the "Terms and Conditions"). The Terms and Conditions govern
transfers of securities and cash within Euroclear, withdrawals of securities and
cash from Euroclear, and receipts of payments with respect to securities in
Euroclear. All securities in Euroclear are held on a fungible basis without
attribution of specific certificates to specific securities clearance accounts.
The
 
                                      112
<PAGE>
Euroclear Operator acts under the Terms and Conditions only on behalf of
Euroclear Participants, and has no record of or relationship with persons
holding through Euroclear Participants.
 
    Distributions on the Book-Entry Notes will be made on each Payment Date by
the Note Trustee to DTC. DTC will be responsible for crediting the amount of
such payments to the accounts of the applicable DTC participants in accordance
with DTC's normal procedures. Each DTC participant will be responsible for
disbursing such payments to the beneficial owners of the Book-Entry Notes that
it represents and to each Financial Intermediary for which it acts as agent.
Each such Financial Intermediary will be responsible for disbursing funds to the
beneficial owners of the Book-Entry Notes that it represents.
 
    Under a book-entry format, beneficial owners of the Book-Entry Notes may
experience some delay in their receipt of payments, since such payments will be
forwarded by the Trustee to Cede & Co. Distributions with respect to Notes held
through Cedel or Euroclear will be credited to the cash accounts of Cedel
Participants or Euroclear Participants in accordance with the relevant system's
rules and procedures, to the extent received by the Relevant Depositary. Such
distributions will be subject to tax reporting in accordance with relevant
United States tax laws and regulations. [See "UNITED STATES FEDERAL INCOME TAX
CONSEQUENCES--Federal Income Tax Consequences to Foreign Investors" and
"--Backup Withholding" herein.] Because DTC can only act on behalf of Financial
Intermediaries, the ability of a beneficial owner to pledge Book-Entry Notes to
persons or entities that do not participate in the Depository system, or
otherwise take actions in respect of such Book-Entry Notes, may be limited due
to the lack of physical certificates for such Book-Entry Notes. In addition,
issuance of the Book-Entry Notes in book-entry form may reduce the liquidity of
such Notes in the secondary market since certain potential investors may be
unwilling to purchase Notes for which they cannot obtain physical certificates.
 
    Monthly and annual reports on the Trust will be provided to Cede & Co., as
nominee of DTC, and may be made available by Cede & Co. to beneficial owners
upon request, in accordance with the rules, regulations and procedures creating
and affecting the Depository, and to the Financial Intermediaries to whose DTC
accounts the Book-Entry Notes of such beneficial owners are credited.
 
    DTC has advised the Note Trustee that, unless and until Definitive Notes are
issued, DTC will take any action permitted to be taken by the holders of the
Book-Entry Notes under the Master Trust Deed only at the direction of one or
more Financial Intermediaries to whose DTC accounts the Book-Entry Notes are
credited, to the extent that such actions are taken on behalf of Financial
Intermediaries whose holdings include such Book-Entry Notes. Cedel or the
Euroclear Operator, as the case may be, will take any other action permitted to
be taken by a Noteholder under the Transaction Documents on behalf of a Cedel
Participant or Euroclear Participant only in accordance with its relevant rules
and procedures and subject to the ability of the Relevant Depositary to effect
such actions on its behalf through DTC. DTC may take actions, at the direction
of the related Participants, with respect to some Notes which conflict with
actions taken with respect to other Notes.
 
    Although DTC, Cedel and Euroclear have agreed to the foregoing procedures in
order to facilitate transfers of Notes among participants of DTC, Cedel and
Euroclear, they are under no obligation to perform or continue to perform such
procedures and such procedures may be discontinued at any time.
 
    Neither the Issuer Trustee, the Servicer nor the Trustee will have any
responsibility for any aspect of the records relating to or payments made on
account of beneficial ownership interests of the Book-Entry Notes held by Cede &
Co., as nominee for DTC, or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.
 
DEFINITIVE NOTES
 
    The Notes of each Class will be issued in registered, certificated form to
the Note Owners of such Class or their nominees ("Definitive Notes"), rather
than to the Depository or its nominee, only if (i) the
 
                                      113
<PAGE>
Depository advises the Note Trustee in writing that it is no longer willing or
able to discharge properly its responsibilities as Depository with respect to
the Notes of such Class, and the Note Trustee is unable to locate a qualified
successor, or (ii) an Event of Default has occurred, and Note Owners
representing not less than 75% of the Invested Amount of such Class advise the
Note Trustee and the Depository through Participants in writing that the
continuation of a book-entry system through the Depository is no longer in the
best interest of the Note Owners of such Class.
 
    Upon the occurrence of any of the events described in the immediately
preceding paragraph, the Depository is required to notify all Participants of
the availability through the Depository of Definitive Notes [and the Note
Trustee will be required to notify all beneficial owners of the occurrence of
such event.] Upon surrender by the Depository of the definitive certificate
representing the Notes of the affected Class and instructions for registration,
the Trustee will issue the Notes of such Class as Definitive Notes, and
thereafter the Trustee will recognize the Note Owners of such Definitive Notes
as Noteholders under the Master Trust Deed, Series Notice and Note Trust Deed.
 
    Distributions of principal and interest on the Notes will be made by the
Trustee directly to Noteholders in accordance with the procedures set forth
herein and in the Master Trust Deed, Series Notice and the Note Trust Deed.
Interest payments and any principal payments on each Payment Date will be made
to Noteholders in whose names the Definitive Notes were registered at the close
of business on the related Record Date. Distributions will be made by check
mailed to the address of such Noteholder as it appears on the register
maintained by the Trustee. The final payment, on any Note, however, will be made
only upon presentation and surrender of such Note at the office or agency
specified in the notice of final distribution to Noteholders. The Trustee will
provide such notice to registered Noteholders mailed not later than the fifth
day of the month of such final distributions.
 
    Definitive Notes will be transferable and exchangeable at the offices of the
transfer agent and registrar, which initially will be the Trustee (in such
capacity, the "Transfer Agent and Registrar"). No service charge will be imposed
for any registration of transfer or exchange, but the Transfer Agent and
Registrar may require payment of a sum sufficient to cover any tax or other
governmental charge imposed in connection therewith. The Transfer Agent and
Registrar will not be required to register the transfer or exchange of
Definitive Notes for the period from the Record Date preceding the due date for
any payment to the Payment Date with respect to such Definitive Notes.
 
MODIFICATION OF MASTER TRUST DEED WITHOUT NOTEHOLDER CONSENT
 
    The Issuer Trustee, the Trust Manager and the Servicer may by way of
supplemental deed alter, add to or modify the Master Trust Deed or a Series
Notice so long as such alteration, addition or modification was effected upon
consent of the Noteholders or Beneficiaries (see "--Modification of Master Trust
Deed with Noteholder Consent" below) or is:
 
        (a) to correct a manifest error or ambiguity or is of a formal,
    technical or administrative nature only;
 
        (b) necessary to comply with the provisions of any statute or regulation
    or with the requirements of any Australian governmental agency;
 
        (c) appropriate or expedient as a consequence of an amendment to any
    statute or regulation or altered requirements of any Government Agency
    (including, without limitation, an alteration, addition or modification
    which is appropriate or expedient as a consequence of the enactment of a
    statute or regulation or an amendment to any statute or regulation or ruling
    by the Australian Commissioner or Deputy Commissioner of Taxation or any
    governmental announcement or statement, in any case which has or may have
    the effect of altering the manner or basis of taxation of trusts generally
    or of trusts similar to any of the Trusts); or
 
                                      114
<PAGE>
       (d) in the opinion of the Issuer Trustee desirable to enable the
    provisions of the Master Trust Deed to be more conveniently, advantageously,
    profitably or economically administered or is otherwise desirable for any
    reason (including to give effect, in the Trust Manager's reasonable opinion,
    to an allocation of expenses).
 
MODIFICATION OF MASTER TRUST DEED WITH NOTEHOLDER CONSENT
 
    Where in the reasonable opinion of the Issuer Trustee a proposed alteration,
addition or modification to the Master Trust Deed (except an alteration,
addition or modification referred to in "--Modification of Master Trust Deed
Without Noteholder Consent" above) is prejudicial or likely to be prejudicial to
the interests of the Noteholders or a Class of Noteholders or the Beneficiaries
such alteration, addition or modification may only be effected by the Issuer
Trustee with the prior consent of the Noteholders or a Class of Noteholders (as
the case may be) under an Extraordinary Resolution of the Noteholders or a Class
of Noteholders (as the case may be) in the Trust or with the prior written
consent of the Beneficiaries (as the case may be).
 
   
[MEETINGS OF VOTING MORTGAGEES AND MEETINGS OF CLASS A NOTEHOLDERS;
  MODIFICATION; CONSENTS; WAIVER
    
 
    The Security Trust Deed contains provisions for convening meetings of the
Voting Mortgagees to, inter alia, enable the Voting Mortgagees to direct or
consent to the Security Trustee taking or not taking certain actions under the
Security Trust Deed, for example to enable the Voting Mortgagees to direct the
Security Trustee to enforce the Security Trust Deed.
 
    For so long as the amounts outstanding under the Offered Notes are 75% or
more of all amounts secured by the Security Trust Deed, the Note Trustee may
direct the Security Trustee to do any act or thing which the Security Trustee is
required to do, or may only do, at the direction of an Extraordinary Resolution
of the Voting Mortgagees.
 
    Neither the Security Trustee nor the Trust Manager may call a meeting of
Voting Mortgagees without the Note Trustee's consent, if the amounts outstanding
under the Notes are 75% or more of all amounts secured by the Security Trust
Deed.
 
    The Note Trust Deed contains provisions for convening meetings of Class A
Noteholders to consider any matter affecting their interests, including the
directing, of the Note Trustee to direct the Security Trustee to enforce the
security under the Security Trust Deed, or the sanctioning by Extraordinary
Resolution of the Class A Noteholders of a modification of the Class A Notes or
the provisions of any of the Relevant Documents, provided that no modification
of certain terms including, inter alia, the date of maturity of the Class A
Notes, or a modification which would have the effect of postponing any day for
payment of interest in respect of any Class A Notes, reducing or cancelling the
amount of principal payable in respect of any Class A Notes or the rate of
interest applicable to any Class A Notes or altering the majority required to
pass an Extraordinary Resolution or altering the currency of payment of any
Class A Notes or an alteration of the date or priority of redemption of the
Class A Notes (any such modification being referred to below as a "Basic Terms
Modification") shall be effective except that, if the Note Trustee is of the
opinion that such a Basic Terms Modification is being proposed by the Issuer
Trustee as a result of, or in order to avoid, an Event of Default, such Basic
Terms Modification may be sanctioned by Extraordinary Resolution of the Class A
Noteholders as described below. The quorum at any meeting of Class A Noteholders
for passing an Extraordinary Resolution shall be two or more persons holding or
representing over 50% of the aggregate of the Class A Notes then outstanding or,
at any adjourned meeting, two or more persons being or representing Class A
Noteholders whatever the aggregate Invested Amount of the Class A Notes so held
or represented except that, at any meeting the business of which includes the

25%, or more of the aggregate Invested Amount of the Class A Notes (irrespective
of class) then outstanding. The Note Trust Deed contains provisions limiting the
powers of the Class B Noteholders, inter alia, to request or direct the Note
Trustee to take any action or to pass an effective Extraordinary Resolution
according to the effect thereof on the interests of the Class B Noteholders.
Except in certain circumstances, the Note Trust Deed imposes no such limitations
on the powers of the Class B Noteholders, the exercise of which will be binding
on the Class B Noteholders, irrespective of the effect on their interests. An
Extraordinary Resolution passed at any meeting of Class A Noteholders shall be
binding on all Class A Noteholders, whether or not they are present at the
meeting. The majority required for an Extraordinary Resolution shall be 75% of
the votes cast in respect of that Extraordinary Resolution.
 
    Pursuant to the terms of the Note Trust Deed, the Note Trustee may agree,
without the consent of the Class A Noteholders, among other things, (i) to any
modification (except a Basic Terms Modification) of, or to the waiver or
authorization of any breach or proposed breach of the Class A Notes (including
the Conditions), or any of the Transaction Documents which is not, in the
opinion of the Note Trustee materially prejudicial to the interests of the Class
A Noteholders or (ii) to any modification of the Class A Notes (including the
Conditions, or any of the Transaction Documents which, in the Note Trustee's
opinion, is to correct a manifest error or is of a formal, minor or technical
nature. The Note Trustee may also, without the consent of the Class A
Noteholders, determine that any Event of Default or any condition, event or act
which with the giving of notice and/or lapse of time and/or the issue of a
certificate would constitute an Event of Default shall not, or shall not subject
to specified conditions, be treated as such. Any such modification, waiver,
authorization or determination shall be binding on the Class A Noteholders and,
unless the Note Trustee agrees otherwise, any such modification shall be
notified to the Class A Noteholders as specified in the Transaction Documents as
soon as practicable thereafter.
 
MEETINGS OF VOTING MORTGAGEES AND MEETINGS OF CLASS B NOTEHOLDERS;
  MODIFICATIONS; CONSENTS; WAIVER
 
    The Security Trust Deed contains provisions for convening meetings of the
Voting Mortgagees to, inter alia, enable the Voting Mortgagees to direct or
consent to the Security Trustee taking or not taking certain actions under the
Security Trust Deed, for example to enable the Voting Mortgagees to direct the
Security Trustee to enforce the Security Trust Deed.
 
    For so long as the amounts outstanding under the Notes are 75% or more of
all amounts secured by the Security Trust Deed, the Note Trustee may direct the
Security Trustee to do any act or thing which the Security Trustee is required
to do, or may only do, at the direction of an Extraordinary Resolution of the
Voting Mortgagees.
 
    Neither the Security Trustee nor the Trust Manager may call a meeting of
Voting Mortgagees without the Note Trustee's consent, if the amounts outstanding
under the Notes are 75% or more of all amounts secured by the Security Trust
Deed.
 
    The Note Trust Deed contains provisions for convening meetings of Class B
Noteholders to consider any matter affecting their interests, including the

security under the Security Trust Deed, or the sanctioning by Extraordinary
Resolution of the Class B Noteholders of a modification of the Class B Notes
(including the Conditions with respect to the Class B Notes) or the provisions
of any of the Transaction Documents, provided that no modification of certain
terms including, inter alia, the date of maturity of the Class B Notes, or a
modification which would have the effect of postponing any day for payment of
interest in respect of any Class B Notes, reducing or cancelling the amount of
principal payable in respect of any Class B Notes or the rate of interest
applicable to any Class B Notes or altering the majority required to pass an
Extraordinary Resolution or altering the currency of payment of any Class B
Notes or an alteration of the date or priority of redemption of the Class B
Notes (any such modification being referred to below as a "Basic Terms
Modification") shall be effective except that, if the Note Trustee is of the
opinion that such a
 
                                      116
<PAGE>
Basic Terms Modification is being proposed by the Issuer Trustee as a result of,
or in order to avoid, an Event of Default, such Basic Terms Modification may be
sanctioned by Extraordinary Resolution of the Class B Noteholders as described
below. The quorum at any meeting of Class B Noteholders for passing an
Extraordinary Resolution shall be two or more persons holding or representing
over 50% of the aggregate of the Class B Notes then outstanding or, at any
adjourned meeting, two or more persons being or representing Class B Noteholders

represented except that, at any meeting the business of which includes the
sanctioning of a Basic Terms Modification, the necessary quorum for passing an
Extraordinary Resolution shall be two or more persons holding or representing
75% or at any adjourned such meeting 25%, or more of the aggregate Invested
Amount of the Class B Notes (irrespective of class) then outstanding. The Note

the exercise of which will be binding on the Class B Noteholders, irrespective
of the effect on their interests. An Extraordinary Resolution passed at any
meeting of Class B Noteholders shall be binding on all Class B Noteholders,
whether or not they are present at the meeting. The majority required for an
Extraordinary Resolution shall be 75% of the votes cast in respect of that
Extraordinary Resolution.
 
   
    Pursuant to the terms of the Note Trust Deed, the Note Trustee may agree,
without the consent of the Class B Noteholders; among other things (i) to any
modification (except a Basic Terms Modification) of; or to the waiver or
authorization of any breach or proposed breach of the Class B Notes (including
the Conditions with respect to the Class B Notes), or any of the Transaction
Documents which is not, in the opinion of the Note Trustee materially
prejudicial to the interests of the Class B Noteholders or (ii) to any
modification of the Class B Notes (including the Conditions with respect to the
Class B Notes, or any of the Transaction Documents which, in the Note Trustee's
opinion, is to correct a manifest error or is of a formal, minor or technical
nature. The Note Trustee may also, without the consent of the Class B
Noteholders, determine that any Event of Default or any condition, event or act
which with the giving of notice and/or lapse of time and/or the issue of a
certificate would constitute an Event of Default shall not, or shall not subject

    approval of the Note Trustee in accordance with the provisions of the
    Security Trust Deed)) is not remedied within 30 days (or such longer period
    as may be specified in the notice, that longer period having been approved

    Transaction Document (other than the Underwriting Agreement, the Redraw
    Facility or the Swap Agreements); or
    
 
   
        (8) without the prior consent of the Security Trustee (that consent

ENFORCEMENT
 
   
    [The Security Trustee must promptly convene a meeting of the Voting
Mortgagees after it receives notice, or has actual knowledge of, an Event of
Default.] The Security Trustee may waive (such waiver, being subject to the
prior written consent of the Note Trustee in accordance with the provisions of
the Security Trust Deed), an Event of Default before it is required to convene a
meeting of Mortgagees if that Event of Default is not (in the opinion of the
Security Trustee) materially prejudicial to the Mortgagees' interests.
    
 
   
    [At the meeting, the Voting Mortgagees must vote by Extraordinary Resolution
(being a resolution passed at a duly convened meeting by a majority consisting
of not less than 75% of the votes capable of being cast by Voting Mortgagees
present in person or by proxy or by written resolution signed by all of the
Voting Mortgagees)] on whether to direct the Security Trustee to:
    
 
        (1) declare the charge to be enforceable;
 
   
        (2) declare all Secured Moneys (including amounts outstanding under the
    Notes plus accrued and unpaid interest) to be immediately due and payable;
    
 
        (3) crystalize the floating charge created under the Security Trust Deed
    in relation to any or all of the Mortgaged Property; and/or
 
        (4) appoint a receiver over the Trust Assets or itself exercise the
    powers that a receiver would otherwise have under the Security Trust Deed.
 
                                      118
<PAGE>
   
    The Security Trustee cannot exercise the powers referred to above unless
directed by an Extraordinary Resolution in the manner outlined above. The
Security Trustee is not obligated to act unless it obtains an indemnity from the
Voting Mortgagees, and is put in funds to the extent to which it may become
liable for the relevant enforcement actions.
    
 
    For so long as the Note Trustee is the only Voting Mortgagee it may direct
the Security Trustee to do any act which the Security Trustee is required to do,
or may only do, at the direction of an Extraordinary Resolution of Voting
Mortgagees.
 
   
    [Neither the Security Trustee nor the Trust Manager may call a meeting of
Voting Mortgagees while the Note Trustee is the only Voting Mortgagee, unless
the Note Trustee otherwise consents.]
    
 
    The Note Trustee will be the only Voting Mortgagee for so long as the
amounts outstanding under the Notes are 75% or more of all amounts secured by
the Security Trust Deed.
 
   
    Upon the occurrence of an Event of Default: (i) if the Note Trustee is the
only Voting Mortgagee; and (ii) if the Note Trustee directs the Security Trustee
to enforce the charge (whether directed to do so by Class A Noteholders or as
the Note Trustee determines on behalf of the Class A Noteholders), the Security
Trustee shall enforce the charge as if directed to do so by an Extraordinary
Resolution of Voting Mortgagees.
    
 
   
    No Mortgagee is entitled to enforce the charge under the Security Trust
Deed, or appoint a receiver or otherwise exercise any power conferred by any
applicable law on charges, otherwise than in accordance with the Security Trust
Deed.
    
 
    "Voting Mortgagee" means:
 
   
    (1) for so long as the amounts outstanding under the Class A Notes and the
Class B Notes are 75% or more of all Secured Moneys, the Note Trustee alone; and
    
 
   
    (2) at any other time: (i) the Note Trustee, acting on behalf of the
Noteholders under the Note Trust Deed and the Security Trust Deed; and (ii) each
other Mortgagee under the Security Trust Deed (other than the Noteholders).
    
 
    Subject to being indemnified in accordance with the Security Trust Deed, the
Security Trustee shall take all action necessary to give effect to any direction
by the Note Trustee where it is the only Voting Mortgagee or to any
Extraordinary Resolution of the Voting Mortgagees and shall comply with all
directions given by the Note Trustee where it is the only Voting Mortgagee or
contained in or given pursuant to any Extraordinary Resolution of the Voting
Mortgagees in accordance with the Security Trust Deed.
 
    No Noteholder is entitled to enforce the Security Trust Deed or to appoint
or cause to be appointed a receiver to any of the assets secured by the Security
Trust Deed or otherwise to exercise any power conferred by the terms of any
applicable law on charges except as provided in the Security Trust Deed.
 
   
    If any of the Class A Notes remains outstanding and are due and payable
otherwise than by reason of a default in payment of any amount due on the Class
A Notes the Note Trustee must not vote under the Security Trust Deed to, or
otherwise direct the Security Trustee to, dispose of the Mortgaged Property
unless either:
    
 
   
       (i) a sufficient amount would be realized to discharge in full all
    amounts owing to the Class A Noteholders, and any other amounts payable by
    the Issuer Trustee ranking in priority to or PARI PASSU with the Class A
    Notes; or
    
 
       (ii) the Note Trustee is of the opinion, reached after considering at any
    time and from time to time the advice of a merchant bank or other financial
    adviser selected by the Note Trustee, that the cash flow receivable by the
    Issuer Trustee (or the Security Trustee under the Security Trust Deed) will
    not
 
                                      119
<PAGE>
    (or that there is a significant risk that it will not) be sufficient, having
    regard to any other relevant actual, contingent or prospective liabilities
    of the Issuer Trustee, to discharge in full in due course all the amounts
    referred to in paragraph (i).
 
   
    Neither the Note Trustee nor the Security Trustee will be liable for any
decline in the value, nor any loss realized upon any sale or other dispositions
made under the Security Trust Deed, of any Mortgaged Property or any other
property which is charged to the Security Trustee by any other person in respect
of or relating to the obligations of the Issuer Trustee or any third party in
respect of the Issuer Trustee or the Notes or relating in any way to the
Mortgaged Property. Without limitation, neither the Note Trustee nor the
Security Trustee shall be liable for any such decline or loss directly or
indirectly arising from its acting, or failing to act, as a consequence of an
opinion reached by it.
    
 
   
    The Note Trustee shall not be bound to vote under the Security Trust Deed,
or otherwise direct the Security Trustee under the Security Trust Deed or to
take any proceedings, actions or steps under, or any other proceedings pursuant
to or in connection with the Security Trust Deed, the Note Trust Deed, any Class
A Notes, unless directed or requested to do so (i) by an Extraordinary
Resolution of the Class A Noteholders or the Class B Noteholders, as
appropriate; or (ii) in writing by the holders of at least one-quarter of the
aggregate Invested Amount of the Class A Notes and then only if the Note Trustee
is indemnified to its satisfaction against all action, proceedings, claims and
demands to which it may render itself liable and all costs, charges, damages and
expenses which it may incur by so doing.
    
 
   
    Only the Security Trustee may enforce the provisions of the Security Trust
Deed and neither the Note Trustee nor any holder of a Class A Note, is entitled
to proceed directly against the Issuer Trustee to enforce the performance of any
of the provisions of the Security Trust Deed, the Class A Notes (including the
Class A Conditions).
    
 
   
    The rights, remedies and discretion of the Class A Noteholders under the
Security Trust Deed including all rights to vote or give instructions or consent
can only be exercised by the Note Trustee on behalf of the Class A Noteholders
in accordance with the Security Trust Deed. The Security Trustee may rely on any
instructions or directions given to it by the Note Trustee as being given on
behalf of the Class A Noteholders, from time to time and need not enquire
whether the Note Trustee or the Noteholders from time to time have complied with
any requirements under the Note Trust Deed or as to the reasonableness or
otherwise of the Note Trustee. The Security Trustee is not obliged to take any
action, give any consent or waiver or make any determination under the Security
Trust Deed without being directed to do so by the Note Trustee or by
Extraordinary Resolution of the Voting Mortgagees in accordance with the
Security Trust Deed.
    
 
    Upon enforcement of the security created by the Security Trust Deed, the net
proceeds thereof may be insufficient to pay all amounts due on redemption to the
Noteholders. The proceeds from enforcement (which will not include amounts
required by law to be paid to the holder of any prior ranking security interest,
the proceeds of or amounts credited to the collateral account under the
Liquidity Facility Agreement and payable to the Liquidity Facility Provider and
the proceeds of cash collateral lodged with and payable to a Swap Provider or
other provider of a Support Facility will be applied in the order of priority as
set out in the Security Trust Deed (see "SECURITY FOR THE NOTES--Priorities
under the Security Trust Deed." Any claims of the Noteholders remaining after
realization of the security and application of the proceeds as aforesaid shall,
except in certain limited circumstances, be extinguished.
 
    See "SECURITY FOR THE NOTES" for a description of the Security Trust Deed
and the order of priorities for the proceeds from the enforcement of the
Security Trust Deed.

                     DESCRIPTION OF THE SERVICING AGREEMENT
 
GENERAL
 
   
    Under the Servicing Agreement, TMC will be appointed as the initial Servicer
of the Housing Loans and custodian of the Relevant Documents relating to the
Housing Loans and Mortgages. The following section contains a summary of the
material terms of the Servicing Agreement. The summary does not purport to be
complete and is subject to the provisions of the Servicing Agreement, which has
been filed as an exhibit to the Registration Statement.
    
 
SERVICING
 
   
    The Servicer manages and services the Housing Loans in accordance with the
Servicing Agreement. To the extent not provided in the Servicing Agreement, the
Servicer shall manage and service the Housing Loans in accordance with the
Procedures Manual as that is interpreted and applied by the Servicer in the
ordinary course of its business. "Procedures Manual" means, in relation to the
Housing Loans, those policies and procedures of Westpac or the Servicer (as the
case may be) relating to the origination, management and enforcement of the
Housing Loans as those policies and procedures are amended in accordance with
the Servicing Agreement and applied from time to time in Westpac's or the
Servicer's ordinary course of business (as the case may be). To the extent not
covered by the Servicing Agreement or the Procedures Manual, the Servicer
manages and services the Housing Loans by exercising the degree of diligence and
care expected of an appropriately qualified servicer of the relevant financial
products and custodian of documents. All acts of the Servicer in servicing the
Housing Loans in accordance with the relevant procedures manual are binding on
the Issuer Trustee.
    
 
POWERS
 
   
    Subject to the servicing standards set forth above and the limitations set
forth below, the Servicer has the express power, among other things, to the
extent such action will not cause an Adverse Effect (that is, an event which
will materially and adversely affect the amount of any payment to be made to any
Noteholder, or will materially and adversely affect the timing of such payment):
    
 
        (1) to waive any fees and break costs which may be collected in the
    ordinary course of servicing the Housing Loans or arrange the rescheduling
    of interest due and unpaid following a default under any Housing Loans;
 
                                      122
<PAGE>
        (2) in its discretion, to waive any right in respect of any Housing
    Loans and Mortgages in the ordinary course of servicing the Housing Loans
    and Mortgages (including in accordance with its normal collection
    procedures); and
 
        (3) to grant an extension of maturity beyond 30 years from the date any
    Housing Loan that relates to a Mortgage was made, when required to do so by
    law or a government agency. The restriction on granting extensions that will
    not have an Adverse Effect shall not apply where the extension is required
    by law or a governmental agency.
 
DELEGATION BY THE SERVICER
 
   
    The Servicer is entitled to delegate its duties under the Servicing
Agreement. The Servicer at all times remains liable for servicing the Housing
Loans and the acts or omissions of any delegate.
    
 
SERVICER UNDERTAKINGS
 
    The Servicer has undertaken, among other things, the following:
 
   
        (1) If so directed by the Issuer Trustee following a Title Perfection
    Event, it will promptly take action to perfect the Issuer Trustee's
    equitable title to the Housing Loans and related Mortgages in the Mortgage
    Pool to full legal title by notifying the Issuer Trustee's interests to
    Borrowers and mortgagors, registering transfers, delivering documents to the
    Issuer Trustee and taking other action required to perfect title.
    
 
   
        (2) In relation to Housing Loans of which Westpac is the legal owner, on
    request from Westpac it will assist Westpac in collecting all moneys due
    under those Housing Loans and Mortgages and pay them into the Collections
    Account not later than the time Westpac would be required to do so.
    
 
   
        (3) In relation to Housing Loans of which the Issuer Trustee is the
    legal owner, it will collect all moneys due under those Housing Loans and
    Mortgages and pay them into the Collections Account not later than the time
    Westpac would be required to do so.
    
 
   
        (4) If a material default occurs in respect of a Housing Loan, it will
    take action in accordance with its normal enforcement procedures to enforce
    the relevant Housing Loan and the related Mortgage to the extent it
    determines to be appropriate.
    
 
   
        (5) Act in accordance with the terms of any Mortgage Insurance Policies,
    not to do or omit to do anything which could be reasonably expected to
    prejudicially affect or limit its rights or the rights of the Issuer Trustee
    under or in respect of a Mortgage Insurance Policy, and promptly make a
    claim under any Mortgage Insurance Policy when it is entitled to do so and
    notify the Trust Manager when each such claim is made.
    
 
   
        (6) It will not consent to the creation or existence of any security
    interest in favor of a third party in relation to any Mortgaged Property
    which would rank before or PARI PASSU with the relevant Housing Loan and
    Mortgage or any other security interest in the Mortgaged Property unless
    priority arrangements are entered into with that third party under which the
    third party acknowledges that the Housing Loan and the Mortgage ranks ahead
    in priority to the third party security interest on enforcement for an
    amount not less than the Unpaid Balance of the Housing Loan plus such other
    amount as the Servicer determines in accordance with the Procedures Manual
    or its ordinary course of business.
    
 
        (7) It will not, except as required by law, release a Borrower or
    otherwise vary or discharge any Housing Loan or Mortgage where it would have
    an Adverse Effect.
 
        (8) It will set the interest rate on the Housing Loans in accordance
    with the requirements of the Series Notice.
 
                                      123

        (9) If directed by the Issuer Trustee following a Title Perfection
    Event, it will take action to perfect the Issuer Trustee's legal title to
    the Housing Loans and related Mortgages.
 
   
        (10) It will give notice in writing to the Issuer Trustee and the Rating
    Agencies of it becoming aware of the occurrence of any Servicer Transfer
    Event.
    
 
   
        (11) It will maintain in effect all qualifications, consents, licenses,
    permits, approvals, exemptions, filings and registrations as may be required
    under any applicable law in order properly to service the Housing Loans and
    Mortgages and to perform or comply with its obligations under this
    Agreement.
    
 
   
        (12) It will notify: (i) the Issuer Trustee and the Trust Manager of any
    event which it reasonably believes is likely to have an Adverse Effect
    promptly after becoming aware of such event; and (ii) the Trust Manager of
    anything else which the Trust Manager reasonably requires regarding any
    proposed modification to any Housing Loan or Mortgage.
    
 
   
        (13) It will provide information reasonably requested by the Issuer
    Trustee or the Trust Manager, with respect to all matters relating to the
    Trust and the assets of the Trust, and the Issuer Trustee or the Trust
    Manager believes reasonably necessary for it to perform its obligations
    under the Transaction Documents, and upon reasonable notice and at
    reasonable times permit the Issuer Trustee to enter the premises and inspect
    the data base in relation to the Trust and the Relevant Documents.
    
 
   
WESTPAC UNDERTAKINGS
    
 
   
    Westpac has undertaken, among other things, the following under the
Servicing Agreement:
    
 
   
        (1) It will maintain in effect all qualifications, consents, licenses,
    permits, approvals, exemptions, filings and registrations as may be required
    under any applicable law in relation to its ownership of any Housing Loan or
    Mortgage and to perform or comply with its obligations under the Servicing
    Agreement; and comply with all Laws in connection with its ownership of any
    Housing Loans and Mortgages where failure to do so would have an Adverse
    Effect.
    
 
   
        (2) It will cooperate with the Servicer in relation to the performance
    by the Servicer of its duties under the Servicing Agreement, including,
    without limitation, in relation to the enforcement of any Housing Loan or
    Mortgage.
    
 
   
        (3) If a material default occurs in respect to a Mortgage, take such
    action as the Servicer directs it to take in accordance with the Servicing
    Agreement.
    
 
   
        (4) It will act in accordance with the terms of any Mortgage Insurance
    Policies, and not do or omit to do anything which could be reasonably
    expected to prejudicially affect or limit the rights of the Issuer Trustee
    under or in respect of a Mortgage Insurance Policy to the extent those
    rights relate to a Housing Loan and the Mortgage.
    
 
   
        (5) It will not consent to the creation or existence of any Security
    Interest in favor of a third party in relation to any Mortgaged Property in
    connection with a Housing Loan and Mortgage:
    
 
   
           (i) without limiting paragraph (5)(ii), unless priority arrangements
       are entered into with that third party under which the third party
       acknowledges that the Housing Loan and Mortgage ranks ahead in priority
       to the third party Security Interest on enforcement for an amount not
       less than the Unpaid Balance of the Housing Loan plus such other amount
       as the Servicer determines in accordance with the Procedures Manual or
       its ordinary course of business; or
    
 
   
           (ii) which would rank before or PARI PASSU with the relevant Housing
       Loan and Mortgage.
    
 
   
        (6) It will not, except as required by law, release an Obligor from any
    amount owing in respect of a Housing Loan or otherwise vary or discharge any
    Housing Loan or Mortgage or enter into any
    
 
                                      124
<PAGE>
   
    agreement or arrangement which has the effect of altering the amount payable
    in respect of a Housing Loan or Mortgage where it would have an Adverse
    Effect.
    
 
   
        (7) It will not release any Housing Loan or Mortgage, reduce the amount
    outstanding under or vary the terms of any Housing Loan or grant other
    relief to an Obligor, if required to do so by any law or if ordered to do so
    by a court, tribunal, authority, ombudsman or other entity whose decisions
    are binding on Westpac. If the order is due to Westpac breaching any
    applicable law then Westpac must indemnify the Issuer Trustee for any loss
    the Issuer Trustee may suffer by reason of the order. The amount of the loss
    is to be determined by agreement with the Issuer Trustee or failing this, by
    Westpac's external auditors.
    
 
   
        (8) It will notify the Servicer immediately of each request by an
    Obligor to borrow further moneys under or in relation to a Mortgage.
    
 
PERFORMANCE OF SERVICES
 
   
    In performing any services under the Servicing Agreement the Servicer shall
have regard to whether its performance of such services does or does not have
any Adverse Effect. The Servicer may ask the Issuer Trustee or the Trust Manager
if, and may rely upon any statement by the Issuer Trustee or the Trust Manager
that, any action or inaction on its part is reasonably likely to, or will, have
an Adverse Effect. The Servicer shall not be liable for a breach of the Servicer
Agreement, or be liable under any indemnity, in relation to any action or
inaction on its part, where it has been notified by the Issuer Trustee or the
Trust Manager that the action or inaction is not reasonably likely to, or will
not have an Adverse Effect.
    
 
SERVICING COMPENSATION AND PAYMENT OF EXPENSES
 
    The Servicer is entitled to a fee (the "Servicing Fee") for servicing the
Housing Loans, payable in arrears on the Payment Date following the end of the
Collection Period. The Servicing Fee is based on the average daily balance of
Housing Loan Principal during the Collection Period and on the actual number of
days in that Collection Period divided by 365 days.
 
    The Servicer must pay from such fee all expenses incurred in connection with
servicing the Housing Loans except for expenses relating to the enforcement of
any Housing Loan or its related securities, the recovery of any amounts owing
under any Housing Loan or any amount repaid to a liquidator or trustee in
bankruptcy pursuant to any applicable law, binding code, order or decision of
any court, tribunal or the like or based on advice of the Servicer's legal
advisers.
 
SERVICER TRANSFER EVENT AND REMOVAL
 
    The Issuer Trustee may only terminate the Servicer's appointment if the
Issuer Trustee determines that a Servicer Transfer Event has occurred and is
continuing. A "Servicer Transfer Event" is any of the following:
 
   
        (1) an Insolvency Event occurs with respect to the Servicer;
    
 
        (2) the Servicer fails to pay any amount within five Business Days of
    receipt of a notice to do so;
 
   
        (3) the Servicer fails to comply with any of its other obligations under
    any Transaction Document and such action has had, or, if continued will
    have, an Adverse Effect (as determined by the Issuer Trustee) and that
    failure is not remedied within 30 days after the Servicer becomes aware of
    that failure by receipt of notice;
    
 
   
        (4) any representation, warranty or certification made by the Servicer
    is incorrect when made and is not waived by the Issuer Trustee or remedied
    to the Issuer Trustee's reasonable satisfaction within 90 days after notice
    from the Issuer Trustee, and the Issuer Trustee determines that breach would
    have an Adverse Effect; or
    
 
                                      125
<PAGE>
        (5) if it is unlawful for the Servicer to perform the services under the
    Servicing Agreement.
 
    In the event of a Servicer Transfer Event, the Issuer Trustee must, upon
notice to the Trust Manager, the Approved Sellers, Westpac, the Servicer and the
Rating Agencies, terminate the rights and obligations of the Servicer with
immediate effect and appoint an Eligible Servicer. Until an Eligible Servicer is
appointed and that Eligible Servicer agrees to act as the servicer, the Issuer
Trustee shall act as the Servicer and is entitled to the fee for so acting.
 
   
    Subject to certain limitations, the Servicer has indemnified the Issuer
Trustee against any expense, loss, damage or liability incurred as a result of a
Servicer Transfer Event or a failure by the Servicer to perform its duties under
the Servicing Agreement.
    
 
RESIGNATION
 
   
    The Servicer must not resign without first giving three months' notice to
the Rating Agencies, the Trust Manager and the Issuer Trustee. If an Eligible
Servicer has not agreed to act as Servicer by the expiration of that notice
period the Issuer Trustee shall act as Servicer and be entitled to the Servicing
Fee.
    
 
                                      126
<PAGE>
DOCUMENT CUSTODY
 
    GENERAL
 
   
    The Servicer will be responsible for custody of the Relevant Documents on
behalf of the Issuer Trustee. The Servicer must hold those documents as
custodian at the direction of the Issuer Trustee in accordance with its standard
safekeeping practices and in the same manner and to the same extent that it
holds similar documents for Westpac. The Servicer will hold custody of the
Relevant Documents in accordance with procedures contained in the Servicing
Agreement. The procedures include the following: (i) keeping the Relevant
Documents for Housing Loans in the Mortgage Pool separate from other documents;
(ii) maintaining reports on movements of the Relevant Documents; and (iii) being
able to locate security packets containing the Relevant Documents.
    
 
    The Servicer will be audited on an annual basis (or more regularly if any
audit gives an adverse finding) in relation to its custodial procedures,
identification of documents, security and tracking systems.
 
TERMINATION OF SERVICER AS DOCUMENT CUSTODIAN
 
    If any of the following occurs:
 
        (1) the Servicer does not comply with the requirements of the Servicing
    Agreement to the satisfaction of the auditor, and a further audit also
    results in an adverse finding by the auditor;
 
        (2) the long term credit rating of the holding company of the Servicer
    is downgraded:
 
        (i) below BBB by Standard & Poor's;
 
        (ii) below Baa2 by Moody's; or
 
   
       (iii) below BBB by Fitch
    
 
        (3) the Servicer is in default under a servicing agreement between it
    and any other person, and by reason of the default that other person removes
    any documents in the Servicer's custody under the servicing agreement where
    that person would otherwise not have been entitled to do so; or
 
   
        (4) a Servicer Transfer Event occurs and is subsisting,
    
 
   
then the Servicer must deliver the Relevant Documents to, or at the direction
of, the Issuer Trustee. If the Servicer does not do so within 10 Business Days
(or such longer period as the Trustee permits), then the Issuer Trustee must
enter the premises where the Relevant Documents are kept, take possession of and
remove the Relevant Documents. If the Issuer Trustee does not have possession of
the documents within that period it must lodge caveats in relation to and/or
take all other action it considers necessary to protect its interests.
    
 
AMENDMENT
 
    The Servicing Agreement may be amended by the parties thereto in writing and
provided that prior notice of any proposed amendment is given to the Rating
Agencies.
 
TERMINATION OF SERVICING AGREEMENT
 
    THE SERVICING AGREEMENT SHALL CONTINUE UNTIL THE EXPIRATION OF THE TERM.
 
    The "Term" means the period from the date of the Servicing Agreement until
the earlier of:
 
        (a) the date on which the Servicing Agreement is terminated pursuant to
    a Servicer Transfer Event;
 
                                      127
<PAGE>
        (b) the date which is one month after the Notes have been redeemed in
    full in accordance with the Transaction Documents and the Trustee ceases to
    have any obligation to any creditor in relation to any Trust;
 
        (c) the date on which the Trustee replaces the Servicer with an Eligible
    Servicer; and
 
        (d) the date on which the Servicer is replaced after resigning pursuant
    to the Servicing Agreement.
 
                             THE LIQUIDITY FACILITY
 
   
    The following section contains a summary of the material terms of the
Liquidity Facility. The summary does not purport to be complete and is subject
to the provisions of the Liquidity Facility, a form of which has been filed as
an exhibit to the Registration Statement.
    
 
GENERAL DESCRIPTION
 
    Under the Liquidity Facility, the Liquidity Facility Provider agrees to make
advances to the Issuer Trustee for the purpose of funding certain income
shortfalls in the Trust, up to an aggregate amount being the lesser of:
 
        (1) A$;
 
   
        (2) the Unpaid Balance of all Performing Loans at that date; and
    
 
        (3) any lesser amount as is agreed in writing between the Liquidity
    Facility Provider, the Issuer Trustee, the Trust Manager and the Rating
    Agencies for each class of Notes, as reduced or cancelled under the
    Liquidity Facility (the "Liquidity Limit").
 
   
    A "Performing Loan" at any date is a Housing Loan which is not Delinquent or
has been Delinquent for less than 90 consecutive days, or if it has been
Delinquent for 90 or more consecutive days was insured under a Mortgage
Insurance Policy at the date of the Liquidity Facility on or before the Closing
Date.
    
 
    A Housing Loan is "Delinquent" if the related Borrower fails to pay any
amount due on the related due date. Delayed payments arising from agreed payment
holidays based on early repayments, or from maternity or paternity leave
repayment reductions will not, by themselves, lead to a Housing Loan being
Delinquent.
 
LIQUIDITY DRAWS
 
   
    If the Trust Manager determines on any Collection Determination Date that
the Available Income of the Trust plus Principal Draws for the Collection Period
relating to that Collection Determination Date is insufficient to meet Total
Payments of the Trust (a "Liquidity Shortfall"), then the Trust Manager must
direct the Issuer Trustee to request a drawing under the Liquidity Facility to
apply towards the Liquidity Shortfall. The drawing will (subject to certain
assumptions as to payment) be the lesser of the Liquidity Shortfall and the
difference between the Liquidity Limit and the aggregate of all outstanding
amounts under the Liquidity Facility (the "Available Liquidity Amount"). A
drawing may only be made by a duly completed drawdown notice signed by an
authorized signatory of the Issuer Trustee.
    
 
CONDITIONS PRECEDENT TO A LIQUIDITY DRAW
 
    A drawing may only be made under the Liquidity Facility (a "Liquidity Draw")
if (among other things) no event of default (see "--Events of Default" below)
subsists at the date of the relevant drawdown notice and the relevant drawdown
date or will result from the provision of the Liquidity Draw.
 
                                      128
<PAGE>
DEPOSIT INTO A COLLATERAL ACCOUNT
 
   
    If at any time the Liquidity Facility Provider's short term credit rating is
less than A-1+ from Standard & Poor's, P-1 from Moody's or F-1+ from Fitch, the
Liquidity Facility Provider must within five Business Days or such longer period
as the Rating Agencies confirm will not result in a downgrade, withdrawal or
qualification of the Offered Notes, deposit into an account held in the name of
the Issuer Trustee (the "Collateral Account") an amount equal to the Available
Liquidity Amount at that time.
    
 
   
    If and for so long as the Liquidity Facility Provider has a short term
credit rating of not lower than A-1 from Standard & Poor's, P-1 from Moody's and
F-1 from Fitch, the Collateral Account shall be maintained with the Liquidity
Facility Provider.
    
 
   
    If at any time the short term credit rating of the bank holding the
Collateral Account is less than A-1 from Standard & Poor's, P-1 from Moody's and
F-1 from Fitch then the balance of the Collateral Account, and all amounts
standing to the credit of the Collateral Account, must (subject to certain
limited restrictions) within five Business Days be transferred to a bank with a
short term credit rating from Standard & Poor's of not lower than A-1+, not
lower than P-1 from Moody's and not lower than F-1+ from Fitch.
    
 
   
    If the short term credit rating of the Liquidity Facility Provider is not
less than A-1 from Standard & Poor's, P-1 from Moody's and F-1 from Fitch, and
the total of the credit balance of the Collateral Account with the Liquidity
Facility Provider plus the amount of all short term investments of the Issuer
Trustee is greater than 20% of the Total Invested Amount, then so much of the
credit balance of the Collateral Account as is necessary for the 20% threshold
not to be breached must (subject to certain limited restrictions) be deposited
with a bank with a short term credit rating from Standard & Poor's of not lower
than A-1+ and not lower than P-1 from Moody's and not lower than F-1+ from
Fitch.
    
 
    Withdrawals from a Collateral Account are restricted to, among other things,
making a Liquidity Draw, paying financial institutions duty and bank account
debit tax (being taxes charged on account transactions) and investing in short
term investments.
 
   
    All interest accrued on the moneys in the Collateral Account shall belong to
the Liquidity Facility Provider. If the Liquidity Facility Provider's short term
credit rating is upgraded to not lower than A-1+/ P-1/F-1+, then the balance in
the Collateral Account must be repaid within five Business Days to the Liquidity
Facility Provider and any advances under the Liquidity Facility thereafter will
be made directly from the Liquidity Facility Provider in the normal course of
business.
    
 
INTEREST ON LIQUIDITY DRAWS
 
    Interest is payable to the Liquidity Facility Provider on the principal
amount drawn under the Liquidity Facility. This interest is payable at the Bank
Bill Rate plus a margin, calculated on days elapsed and a year of 365 days.
Interest is payable on each Payment Date and on repayment of a drawing. Unpaid
interest will capitalize, and interest accrues on any unpaid interest.
 
COMMITMENT FEE
 
    A commitment fee accrues daily from the date of the Liquidity Facility on
the Available Liquidity Amount, and is payable on each Payment Date and on
termination of the facility.
 
    The commitment fee is calculated on the actual number of days elapsed and a
year of 365 days.
 
REPAYMENT OF LIQUIDITY DRAWINGS
 
    If an amount has been drawn down under the Liquidity Facility, the principal
amount is repayable on the following Payment Date, to the extent that amounts
are available for this purpose under the Series Notice; see "DESCRIPTION OF THE
OFFERED NOTES--Distribution of Total Available
 
                                      129
<PAGE>
Funds" above. It is not an event of default if the Issuer Trustee does not have
funds available to repay the full amount outstanding on the following Payment
Date.
 
EVENTS OF DEFAULT
 
    It is an event of default under the Liquidity Facility (whether or not such
event is within the control of the Issuer Trustee) if:
 
        (1) at any time the Available Liquidity Amount is zero, and the Issuer
    Trustee fails to pay an amount payable by it under the Liquidity Facility
    within 10 Business Days of its due date;
 
        (2) an amount is available for payment under the Liquidity Facility and
    the Issuer Trustee does not pay that amount;
 
        (3) an Insolvency Event occurs in relation to the Trust;
 
        (4) an Insolvency Event occurs in relation to the Issuer Trustee, and a
    successor trustee of the Trust is not appointed within 30 days of that
    Insolvency Event;
 
        (5) the Termination Date occurs in relation to the Trust; or
 
        (6) all or any part of the Liquidity Facility is terminated or is or
    becomes void, illegal, invalid or unenforceable.
 
CONSEQUENCES OF DEFAULT
 
    In addition to rights provided by law or any Transaction Document, at any
time after an event of default has occurred under the Liquidity Facility
(whether or not it is continuing), the Liquidity Facility Provider may do all or
any of the following by notice to the Issuer Trustee and the Trust Manager:
 
        (1) declare all moneys actually or contingently owing at that time
    immediately due and payable, and the Issuer Trustee must immediately pay the
    total amount of all outstanding Liquidity Draws, together with accrued
    interest and fees and all other such moneys; and
 
        (2) cancel the Liquidity Limit with effect from any date specified in
    that notice.
 
TERMINATION
 
    The Liquidity Facility will terminate on the earliest of the following to
occur:
 
   
        (1) the date on which the Issuer Trustee enters into a replacement
    liquidity facility as previously notified to the Rating Agencies;
    
 
        (2) one month after the Notes have been redeemed in full in accordance
    with the Master Trust Deed;
 
        (3) following an event of default under the Liquidity Facility, the date
    on which the Liquidity Facility Provider declares the Liquidity Facility
    terminated; and
 
   
        (4) the date on which the Issuer Trustee has cancelled the Liquidity
    Limit in full.
    
 
   
    Cancellation is conditional on the Rating Agencies confirming that such
cancellation will not result in a downgrade, withdrawal or qualification of the
credit rating assigned by the Rating Agencies to the Notes.

                       DESCRIPTION OF THE SWAP AGREEMENTS
 
DESCRIPTION OF INTEREST RATE SWAP AGREEMENTS
 
   
    The following section contains a summary of the material terms of the Swap
Agreements, which the Issuer Trustee will enter into with the Interest Rate Swap
Provider. The summary does not purport to be complete and is subject to the
provisions of the Swap Agreements.
    
 
FIXED RATE AND VARIABLE RATE BASIS SWAPS
 
    The Issuer Trustee will enter into a Variable Rate Basis Swap and two Fixed
Rate Basis Swaps with Westpac, in its capacity as the provider of the Variable
Rate Basis Swap and Westpac, in its capacity as the provider of the Fixed Rate
Basis Swaps (together the "Interest Rate Swap Provider"). Such swaps will use
the ISDA Master Agreement amended by a supplementary schedule and a confirmation
for each swap. See "ORIGINATOR OF THE HOUSING LOANS" for a description of the
Interest Rate Swap Provider.
 
    A Variable Rate Basis Swap will be used to hedge the basis risk between the
floating rate obligations of the Trust (including Interest payable on the Notes)
and the variable rate set, as permitted by the relevant Housing Loan agreements,
at the discretion of Westpac. The Variable Rate Basis Swap will include those
loans with a concessional fixed rate of interest for the first 12 months,
converting to the standard variable rate after that period. The Issuer Trustee
will pay an amount based on the applicable daily weighted average variable
housing rates and receive the Bank Bill Rate (as defined herein) plus a fixed
margin. The margin is fixed for the life of the swap and has been set having
regard to the ongoing obligations of the Trust.
 
    Two Fixed Rate Basis Swaps will be used to hedge the basis risk between the
floating rate obligations of the Trust (including Interest payable on the Notes)
and the discretionary fixed rates set by Westpac on the Housing Loans which are
subject to a fixed rate of interest (not including those loans with a
concessional fixed rate of interest for the first 12 months, which converts to
the standard variable rate after that period).
 
    The first Fixed Rate Basis Swap will be used to hedge the basis risk
occurring when Borrowers switch from a variable rate of interest to a Fixed Rate
of interest after the Cut-Off Date. The Issuer Trustee will pay the applicable
daily weighted average Fixed Rate and the Interest Rate Swap Provider will pay
the Bank Bill Rate plus a fixed margin. The margin is fixed for the life of the
swap and has been set having regard to the ongoing obligations of the Trust.
 
   
    The second Fixed Rate Basis Swap will be entered into as at the Closing Date
to hedge those Housing Loans subject to a Fixed Rate of interest as of the
Cut-Off Date. The Issuer Trustee will pay the applicable daily weighted average
Fixed Rate and the Interest Rate Swap Provider will pay the Bank Bill Rate plus
a fixed margin. The margin is fixed for the life of the swap and has been set
based on the actual margin on the Fixed Rate Housing Loans and the prevailing
wholesale market rate existing at or about the Cut-Off Date.
    
 
    All Housing Loans being charged a Fixed Rate of interest as of the Cut-Off
Date have a maximum Fixed Rate period of 5 years.
 
DOWNGRADE OF INTEREST SWAP PROVIDER
 
   
    If there is a downgrading of the Interest Rate Swap Provider's long term or
short term debt rating below A-1+, A2 or F-1+ by either Standard & Poor's,
Moody's or Fitch, respectively, the Interest Swap Provider will either:
    
 
        (1) provide cash collateral security sufficient to enable Standard &
    Poor's, Moody's and Fitch to confirm that the downgrade will not cause a
    reduction in or a withdrawal of the rating of the Notes; or
 
        (2) arrange for a suitably rated counterparty to intermediate the swap
    or act as substitute swap provider.
 
                                      131
<PAGE>
TERMINATION
 
    The following events are events of default under the Interest Rate Swap
Agreements: (i) failure by Westpac or the Issuer Trustee to make, when due, any
payment or delivery required by the agreement and such failure is not remedied
by the tenth local business day; and (ii) an Insolvency Event has occurred in
respect of Westpac or the Issuer Trustee; provided, however, that an Insolvency
Event in relation to the Issuer Trustee in its personal capacity is not an event
of default if the relevant Swap is novated within 30 Business Days of that
Insolvency Event and the novation will not cause a reduction or withdrawal of
the rating of the Notes. Upon novation of the Swap, the successor Issuer Trustee
will assume the rights and obligations of the Issuer Trustee under the Interest
Rate Swap.
 
   
    An event which constitutes illegality will be a termination event under the
Interest Rate Swap Agreements. If there is a downgrading of the Interest Rate
Swap Provider's short term debt rating below A-l+, A2 or F-1+ by either Standard
& Poor's, Moody's or Fitch and the Interest Rate Swap Provider fails to act, as
described in "--Downgrade of Interest Swap Provider" above, it will be an
"Additional Termination Event" under the Variable Rate Basis Swap. If under
similar circumstances the Interest Rate Swap Provider fails to establish certain
collateral arrangements it will be an "Additional Termination Event" under each
of the Fixed Rate Basis Swaps only at the discretion of the Issuer Trustee. The
"Automatic Early Termination" provisions under the Fixed and Variable Rate Basis
Swaps do not apply.
    
 
   
    Upon the termination of an Interest Rate Basis Swap, a termination payment
calculated pursuant to the Loss Method (as defined in such Interest Rate Basis
Swap) will be due to be paid by the Issuer Trustee to the Interest Rate Swap
Provider or by the Interest Rate Swap Provider to the Issuer Trustee. The
termination payment with respect to the Variable Rate Basis Swap will be zero.
The Issuer Trustee may look to any cash collateral security posted by the
Interest Rate Swap Provider relating to the terminated Interest Rate Basis Swap
for satisfaction of the Interest Rate Swap Provider's termination payment.
    
 
   
NOVATION
    
 
   
    Upon the novation of a Interest Rate Swap Agreement, either the Interest
Rate Swap Provider will pay to the substitute Interest Rate Swap Provider an
up-front premium or the substitute Interest Rate Swap Provider will pay to the
Interest Rate Swap Provider an up-front premium to preserve the economic
equivalent of the mark-to-market value of the swap transaction as of the date of
novation. The Issuer Trustee will not bear any risk with respect to the novation
of an Interest Rate Swap unless the Interest Rate Swap Provider is unable to pay
any required up-front premium and there is insufficient cash collateral security
posted with respect to such Interest Rate Swap to cover such premium.
    
 
THRESHOLD RATE
 
    If at any time the Variable Rate Basis Swap is terminated, the Trust Manager
must, on each Collection Determination Date following that termination,
calculate the minimum rate of interest that must be set on the Housing Loans
which are subject to a discretionary variable rate, in order to cover (assuming
all counterparties to the Transaction Documents, the Housing Loans and any
Mortgages and other relevant securities meet their obligations), when aggregated
with the income produced by all other Housing Loans and taking into account the
other Swap Agreements, the obligations of the Trust (the "Threshold Rate"). If
the Servicer is notified of the Threshold Rate, it is required, subject to the
terms of the relevant Housing Loans, to ensure that the rate of interest on each
relevant discretionary variable rate Housing Loan is not less than the Threshold
Rate (see "DESCRIPTION OF THE SERVICING AGREEMENT" above).
 
DESCRIPTION OF CURRENCY SWAP
 
   
    The following summary describes certain terms of the Currency Swap, which
the Issuer Trustee will enter into with Morgan Guaranty Trust Company of New
York, acting through its Sydney Branch and Westpac (together, the "Currency Swap
Providers" and together with the Interest Rate Swap Provider, the "Swap
Providers"). The summary does not purport to be complete and is qualified in its
entirety by reference to the provisions of the Currency Swap. The Currency Swap
is provided on a joint and several basis by Westpac and Morgan Guaranty Trust
Company of New York, acting through its Sydney Branch.

<PAGE>
   
    Collections in relation to the Housing Loans and related Mortgages and under
the Variable Rate Basis Swap and the Fixed Rate Basis Swap ("Collections") will
be denominated in Australian dollars. However, the payment obligations of the
Issuer Trustee in relation to Interest and principal on the Notes are
denominated in United States dollars. To hedge its currency exposure, the Issuer
Trustee will enter into two distinct swap transactions, relating to the Class A
Notes and the Class B Notes, respectively (together, the "Currency Swap") with
the Currency Swap Providers. The Currency Swap will be evidenced by two swap
confirmations which will be governed by an ISDA Master Agreement dated       ,
1998, as supplemented by the Schedule thereto (such ISDA Master Agreement,
Schedule and swap confirmations, the "Agreement"). Under the Currency Swap, the
Issuer Trustee is required to pay to the Currency Swap Providers amounts in A$
equal to the amount of any Principal Collections received by the Issuer Trustee
and the Currency Swap Providers are required to pay to or at the direction of
the Issuer Trustee an amount denominated in US$ which is equivalent to such A$
payment (calculated by reference to an exchange rate which is fixed at the
Closing Date and set forth in the swap confirmations). In addition, under the
Currency Swap on each Payment Date the Issuer Trustee will make A$ floating rate
payments to the Currency Swap Providers and the Currency Swap Providers will
make US$ floating rate payments which are equivalent in amount to the Interest
payable in US$ to the Noteholders. If on any Payment Date, the Issuer Trustee
does not make the full floating payment, the US$ floating rate payment to be
made by the Currency Swap Providers on such Payment Date will be reduced by the
same proportion as the reduction in the payment from the Issuer Trustee.
    
 
   
    Subscription amounts for the Notes will be paid by investors in US$, but the
consideration for the purchase by the Issuer Trustee of equitable title to the
Housing Loans and related Mortgages will be in A$. Under the Currency Swap, an
amount equal to the US$ subscription amounts will be paid to the Currency Swap
Providers, which will pay the A$ Equivalent of such amounts to the Issuer
Trustee. See "CURRENCY SWAP PROVIDERS" below for more information.
    
 
   
    In the event that one of the Currency Swap Providers is ever downgraded
below a specified level such that the rating on the Class A Notes would be
downgraded or qualified, the Currency Swap Providers will give a commitment to
provide cash collateral or other credit enhancement in respect of the Currency
Swap.
    
 
   
    The Currency Swap comprises two distinct swap transactions, relating to the
Class A Notes and the Class B Notes respectively. On the Closing Date the Issuer
Trustee will be obliged to pay to the Currency Swap Providers an amount equal to
the proceeds of the issue of the Notes in US$. In return the Issuer Trustee will
be paid the A$ equivalent of that US$ amount (calculated by reference to an
exchange rate which is fixed by the Closing Date (in the Swap confirmations)).
    
 
   
    The cash flow methodology in the Series Notice provides that amounts equal
to certain amounts allocated from Principal Collections and (in some cases) from
Excess Available Income are paid by the Issuer Trustee to the Currency Swap
Providers on each Payment Date. Under the Currency Swap the Currency Swap
Providers pay to the Issuer Trustee, against receipt of the A$ denominated
payment, an amount denominated in US$ which is equivalent to the A$ payment from
the Issuer Trustee (calculated by reference to the exchange rate referred to
above).
    
 
   
    The cash flow methodology in the Series Notice provides that the Issuer
Trustee also pays to the Currency Swap Providers amounts equal to scheduled A$
floating rate payments (the A$ Class A Interest Amount and the A$ Class B
Interest Amount) on each Payment Date. Under the Currency Swap the Currency Swap
Providers pay to the Issuer Trustee on each Payment Date, against receipt of
those A$ denominated payments, scheduled US$ floating rate payments equivalent
to the Interest due to the Noteholders. If on any Payment Date the Issuer
Trustee does not make the full scheduled A$ payment, the scheduled US$ payment
from the Currency Swap Providers will be reduced by the same proportion as the
reduction in the payment from the Issuer Trustee.
    
 
   
    The Series Notice requires that the US$ amounts received by the Issuer
Trustee from the Currency Swap Providers are paid to the Noteholders in
accordance with their entitlements and the priorities set out in "DESCRIPTION OF
THE OFFERED NOTES."

TERMINATION OF THE CURRENCY SWAP
    
 
   
    Under the Currency Swap, the Currency Swap Providers have the following
rights to terminate:
    
 
        (1) An immediate right of termination if the Issuer Trustee fails to
    make a payment under the Currency Swap within the applicable grace period of
    10 Business Days.
 
   
        (2) If due to change in law it becomes illegal for either party to make
    or receive payments or comply with any other material provision of the
    Currency Swap, the Currency Swap requires each party to make certain efforts
    to transfer their rights and obligations to avoid this illegality. If those
    efforts are not successful then the Currency Swap Providers will have the
    right to terminate. These provisions relating to termination following an
    illegality have been modified so that they are not triggered by the
    introduction of certain exchange controls by any Australian Government body.
    
 
   
        (3) The Currency Swap Providers have the limited right to terminate
    where it is required to gross-up or receive payments from which amounts have
    been withheld.
    
 
        (4) Any Event of Default under the Conditions of the Notes occurs.
 
   
    If neither the Currency Swap Providers nor the Issuer Trustee elect to
terminate the Currency Swap following an Event of Default under the Conditions
of the Notes occurs, then the Note Trustee may do so.
    
 
TERMINATION BY THE ISSUER TRUSTEE
 
    There are a number of circumstances in which the Issuer Trustee has the
right to terminate the Currency Swap. In each of these cases it is only
permitted to exercise that right if directed by the Trust Manager and with the
prior written consent of the Note Trustee:
 
   
        (1) Where the Currency Swap Providers fail to make a payment under the
    Currency Swap within any applicable grace period or the Currency Swap
    Providers become insolvent or merge into another entity without that entity
    properly assuming responsibility for the obligations of the Currency Swap
    Providers under the Currency Swap.
    
 
   
        (2) If it becomes illegal for either party to make or receive payments
    under the Currency Swap or perform any of its other material obligations
    under it, both the Issuer Trustee and the Currency Swap Providers are
    obliged to make certain efforts to transfer their rights and obligations to
    avoid that illegality. If those efforts fail the Currency Swap may be
    terminated.
    
 
   
        (3) If the Issuer Trustee becomes obliged under the Currency Swap to
    receive payments from which amounts have been withheld or deducted
    (including where this situation arises from a merger affecting the Currency
    Swap Providers).
    
 
        (4) Any Event of Default under the Conditions of the Notes occurs.
 
        (5) The Currency Swap may also be terminated if the Issuer Trustee
    becomes obliged to make a withholding or deduction in respect of the Notes
    and the Notes are redeemed as a result or if the Issuer Trustee is or will
    be subject to certain increased costs or expenses.
 
   
    If neither the Currency Swap Providers nor the Issuer Trustee elect to
terminate the Currency Swap following an Event of Default under the Conditions
of the Notes occurs, then the Note Trustee may do so.
    
 
   
    The Issuer Trustee (and the Note Trustee) may only terminate the Currency
Swap following prior consultation by the Note Trustee with the Currency Swap
Providers as to the timing of termination.
    
 
TERMINATION PAYMENTS
 
   
    On the Termination Date or the Early Termination Date (each as defined in
the Currency Swap) in respect of the Currency Swap, a termination payment will
be due to be paid by the Issuer Trustee to the Currency Swap Providers or to the
Issuer Trustee by the Currency Swap Providers in respect of the Currency Swap.
There is no guarantee that upon any such termination the funds realized from the
sale of the relevant Loans and Mortgages plus or minus (as the case may be) the
termination payment due in respect of the Currency Swap will be sufficient to
pay in full amounts owing to the holders of the relevant Notes.
    
 
                                      134
<PAGE>
   
    The termination payment in respect of a Currency Swap will be determined on
the basis of quotations from four leading dealers in the relevant market
(selected by the Currency Swap Providers) to enter into a replacement
transaction that would have the effect of preserving the economic equivalent of
any payment that would, but for the early termination, have been required under
the terms of the Currency Swap.
    
 
REPLACEMENT OF CURRENCY SWAP
 
   
    If the Currency Swap is terminated, the Issuer Trustee may at the direction
of the Trust Manager enter into a currency swap which replaces the Currency Swap
(other than by way of transfer under section 6(b) of the Currency Swap) (a
"Replacement Currency Swap") if and only if the amount payable (if any) to the
Issuer Trustee by the provider of the Replacement Currency Swap as an up front
premium to enter into the Replacement Currency Swap is greater than or equal to
the termination payment payable (if any) to the Currency Swap Providers by the
Trustee on termination of the Currency Swap. If the condition in the previous
sentence is satisfied, the Issuer Trustee may enter into the Replacement
Currency Swap and if it does so it must direct the amount payable (if any) by
the provider of the Replacement Currency Swap to be paid directly to the
Currency Swap Providers in satisfaction of and to the extent of the Issuer
Trustee's obligation to pay the termination payment to the Currency Swap
Providers.
    
 
   
DOWNGRADE OF CURRENCY SWAP PROVIDERS
    
 
   
    The Currency Swap Providers, severally, will give a commitment to provide
cash collateral or other credit enhancement in respect of the Currency Swap in
the event that the rating of one of the Currency Swap Providers is ever
downgraded below a specified level, such that the Rating Agencies would
downgrade the rating on the Class A Notes.

                   CERTAIN LEGAL ASPECTS OF THE HOUSING LOANS
 
   
    The following discussion contains summaries of legal aspects of Australian
retail housing loans and mortgages that are general in nature. The summaries do
not purport to be complete. In addition, certain of those legal aspects are
governed by state law (which laws may differ substantially from state to state),
and the summaries do not reflect the particular laws of any particular state or
encompass all relevant laws of all states in which any Mortgaged Property may be
situated. The summaries are subject to the applicable Australian federal and
state laws governing real property and the granting and enforcement of security
over real property.
    
 
GENERAL
 
    Each Housing Loan will be secured by a mortgage which is to have a first
ranking priority over all other mortgages granted by the relevant Borrower and
over all unsecured creditors of the Borrower (except in respect of certain
statutory rights such as some rates and taxes, which are granted statutory
priority). The Borrower is prohibited under its loan documents from creating
another mortgage or other security interest over the relevant Mortgaged Property
without the consent of Westpac. There are two parties to a mortgage, the
mortgagor, who is the borrower and homeowner (or, where the relevant loan is
guaranteed and the guarantee is secured by a mortgage, the guarantor) and who
grants the mortgage over their property, and the mortgagee who is the lender.
 
    Under Torrens title, registration of a mortgage using the prescribed form
executed by the mortgagor is required in order for the mortgagee to obtain the
remedies of a mortgagee granted by statute and the relevant priorities against
other secured creditors. To this extent the mortgagee is said to have a legal
(i.e., registered) title. However, registration does not transfer title in the
property--the mortgagor remains as legal owner. Rather, the Torrens mortgage
operates as a statutory charge. The mortgagee does not obtain an estate in the
property but does have an interest in the land which is marked on the register
and the "certificate of title" for the property. A search of the register by any
subsequent lender will reveal the existence of the prior mortgage. See "--Nature
of Housing Loans as Security" below for a further description of Torrens title.
 
    A mortgagee will retain the relevant certificate of title until the mortgage
is discharged. Although the certificate is not a document of title as such, the
procedure for replacement is sufficiently onerous to act as a deterrent against
most mortgagor fraud. In addition, failure to retain the certificate may in
certain circumstances constitute negligent conduct resulting in a postponement
of the mortgagee's priority to a later secured creditor.
 
    Once the mortgagor has repaid the debt, a discharge is lodged with the
registrar and the mortgage is noted as having been released.
 
NATURE OF HOUSING LOANS AS SECURITY
 
    There are a number of different forms of title to land in Australia. The
most common forms of title in Australia, and the only form of title which may
constitute Mortgaged Property is "Torrens title."
 
TORRENS TITLE
 
    "Torrens title" land is freehold title, interests in which are created by
registration in a central land registry of the relevant State or Territory. Each
parcel of land is represented by a specific certificate of title. The original
certificate is retained by the registry, and in most States a duplicate
certificate is issued to the owner. Any dealing with the relevant land is
carried out by pro forma instruments which become effective on registration.
 
    Ordinarily the relevant certificate of title (or any registered plan
referred to in it) will reveal the position and dimensions of the land, the
present owner, and any leases, mortgages and registered
 
                                      136
<PAGE>
easements to which it is subject. The certificate is conclusive evidence (except
in limited circumstances, such as fraud) of the matters stated in it.
 
STRATA TITLE
 
    "Strata title" was developed to facilitate the creation of, and dealings
with, apartment units (which are similar to condominiums in the United States)
and is governed by the legislation of the State or Territory in which the
property is situated. Under strata title, the relevant land is divided into the
relevant number of units. Each proprietor has title to, and may freely dispose
of, their unit. All proprietors are members of a "body corporate", which
monitors compliance with rules governing the apartment block. Certain parts of
the property, such as stairwells, entrance lobbies and the like are known as
"common property" and are owned by the body corporate as a whole rather than by
individual proprietors.
 
    Only Torrens title land can be the subject of strata title in this way, and
so the provisions referred to in this section in relation to Torrens title apply
to the title in a unit held by a strata proprietor.
 
TAKING SECURITY OVER LAND
 
    The law relating to the granting of securities over real property is made
complex by the fact that each State and Territory has separate governing
legislation. The following is a brief overview of general issues involved in
taking security over land.
 
    Under Torrens title, registration of a mortgage using the prescribed form
executed by the mortgagor is required in order for the mortgagee to obtain the
remedies of a mortgagee granted by statute and the relevant priorities against
other secured creditors. To this extent the mortgagee is said to have a legal
(i.e., registered) title. However, registration does not transfer title in the
property--the mortgagor remains as legal owner. Rather, the Torrens mortgage
operates as a statutory charge. The mortgagee does not obtain an estate in the
property but does have an interest in the land which is marked on the register
and the "certificate of title" for the property. A search of the register by any
subsequent lender will reveal the existence of the prior mortgage.
 
   
    In most States and Territories, a mortgagee will retain a duplicate
certificate of title (which mirrors the original certificate of title held at
the relevant land registry office). Although the certificate is not a document
of title as such, the procedure for replacement is sufficiently onerous to act
as a deterrent against most mortgagor fraud. Failure to retain the certificate
may in certain circumstances constitute negligent conduct resulting in a
postponement of the mortgagee's priority to a later secured creditor.
    
 
   
    In Queensland, under the Land Title Act 1994, duplicate certificates of
title are no longer issued to mortgagees as a matter of practice. A record of
the title is stored on computer at the land registry office and the mortgage is
registered on that computerized title.
    
 
    Once the mortgagor has repaid the debt, a discharge executed by the
mortgagee is lodged with the registrar by the mortgagor or the mortgagee and the
mortgage is noted as having been released.
 
WESTPAC AS MORTGAGEE
 
    Westpac is, and until a Title Perfection Event occurs intends to remain, the
registered mortgagee of all the Mortgages. The relevant Borrowers will not be
aware of the equitable assignment of the Housing Loans and Mortgages to the
Issuer Trustee.
 
    Prior to any Title Perfection Event Westpac, or the Servicer on its behalf,
will undertake any necessary enforcement action with respect to defaulted
Housing Loans and Mortgages. Following a Title Perfection Event, the Issuer
Trustee is entitled (under an irrevocable power of attorney granted to it by
Westpac) to be registered as mortgagee of the Mortgages. Until that registration
is achieved, the Issuer Trustee or the Trust Manager is entitled to lodge
caveats on the register to notify its interest publicly. See "APPENDIX
I--GLOSSARY OF AUSTRALIAN LEGAL TERMS."
 
ENFORCEMENT OF HOUSING LOANS
 
    Subject to the discussion below, if a Borrower defaults under a Housing
Loan, the loan documents provide that all moneys under the loan may be declared
immediately due and payable. The lender may sue
 
                                      137
<PAGE>
to recover all outstanding principal, interest and fees under the personal
covenant of the borrower contained in the loan documents to repay those amounts.
In addition, the lender may enforce a registered mortgage in relation to the
defaulted loan. Enforcement may occur in a number of ways, including the
following.
 
        (a) The mortgagee may enter into possession of the property. If it does
    so, it does so in its own right and not as agent of the mortgagor, and so
    may be personally liable for mismanagement of the property and to third
    parties as occupier of the property.
 
        (b) The mortgagee may, in limited circumstances, lease the property to
    third parties.
 
        (c) The mortgagee may foreclose on the property--that is, extinguish the
    mortgagor's title to the property so that the mortgagee becomes the absolute
    owner of the property (a remedy that is, because of procedural constraints,
    rarely used). If the mortgagee forecloses on the property, it loses the
    right to sue the borrower under the personal covenant to repay and can look
    only to the value of the property for satisfaction of the debt.
 
        (d) The mortgagee may appoint a receiver to deal with income from the
    property or exercise certain other rights delegated to the receiver by the
    mortgagee. Unlike a mortgagee in possession, a receiver is the agent of the
    mortgagor and so in theory the mortgagee is not liable for the receiver's
    acts or as occupier of the property. In practice, the receiver will require
    indemnities from the mortgagee that appoints it.
 
        (e) The mortgagee may sell the property, subject to various duties to
    ensure that the mortgagee exercises proper care in relation to the sale.
    This power of sale is usually expressly contained in the mortgage documents,
    and is also implied into registered mortgages under the relevant Torrens
    title legislation. The Torrens title legislation prescribes forms and
    periods of notice to be given to the mortgagor prior to enforcement.
 
        A sale under a mortgage may be by public auction or private treaty. Once
    registered, the purchaser of property sold pursuant to a mortgagee's power
    of sale becomes absolute owner of the property.
 
    A mortgagee's ability to call all amounts under a housing loan or enforce a
mortgage which is subject to the Consumer Credit Legislation is limited by
various demand and notice procedures which are required to be followed. For
example, as a general rule enforcement cannot occur unless the relevant default
is not remedied within 30 days after a default notice is given. Borrowers may
also be entitled to initiate negotiations with the mortgagee for a postponement
of enforcement proceedings.
 
PENALTIES AND PROHIBITED FEES
 
    Australian courts will not enforce an obligation of a borrower to pay
default interest on delinquent required payments if the court determines that
the relevant default interest rate is a penalty. Certain jurisdictions prescribe
a maximum recoverable interest rate, although in most jurisdictions there is no
specified threshold rate to determine what is a penalty. In those circumstances,
whether a rate is a penalty or not will be determined by reference to such
factors as the prevailing market interest rates. The Consumer Credit Legislation
does not impose a limit on the rate of default interest, but a rate which is too
high may entitle the borrower to have the loan agreement re-opened on the ground
that it is unjust. Under the Corporations Law, the liquidator of a company may
avoid a loan under which an extortionate interest rate is levied.
 
    The Consumer Credit Legislation requires that any fee or charge to be levied
by the lender must be provided for in the contract, otherwise it cannot be
levied. The regulations under the Consumer Credit Legislation may also from time
to time prohibit certain fees and charges. The Consumer Credit legislation also
requires that establishment fees, termination fees and prepayment fees must be
reasonable otherwise they may be reduced or set aside.
 
CONSUMER CREDIT LEGISLATION
 
    Some of the Housing Loans are regulated by consumer credit legislation (the
"Consumer Credit Legislation"). Under that legislation, a Borrower may have a
right to apply to a court to:
 
                                      138
<PAGE>
        (1) vary the terms of his or her Housing Loan on the grounds of hardship
    or that it is an unjust contract;
 
        (2) reduce or cancel any interest rate payable on the Housing Loan which
    is unconscionable;
 
        (3) have certain provisions of the Housing Loan or relevant Mortgage
    which are in breach of the legislation declared unenforceable; or
 
        (4) obtain restitution or compensation from the Issuer Trustee, in
    relation to any breaches of the Consumer Credit Legislation in relation to
    the Housing Loan or relevant Mortgage.
 
    Any such order may affect the timing or amount of interest or principal
payments or repayments under the relevant Housing Loan (which might in turn
affect the timing or amount of interest or principal payments or repayments
under the Offered Notes).
 
   
    In addition, a mortgagee's ability to enforce a mortgage which is subject to
the Consumer Credit Legislation is limited by various demand and notice
procedures which are required to be followed. For example, as a general rule
enforcement cannot occur unless the relevant default is not remedied within 30
days after a default notice is given. Borrowers may also be entitled to initiate
negotiations with the mortgagee for a postponement of enforcement proceedings.
Such procedures and negotiations may also affect the timing or amount of
interest or principal payments or repayments under the Housing Loans.
    
 
    Breaches of the Consumer Credit Legislation may also lead to civil penalties
or criminal fines being imposed on Westpac, for so long as it holds legal title
to the Housing Loans and the Mortgages. If the Issuer Trustee acquires legal
title, it will then become primarily responsible for compliance with the
Consumer Credit Legislation. The Issuer Trustee will (subject to limited
exceptions) be indemnified out of the assets of the Trust for its liabilities
under the Consumer Credit Legislation. If the Issuer Trustee is indemnified with
respect to such liabilities out of the assets of the Trust, proceeds of the
Trust may be insufficient to make all payments provided for under the Offered
Notes.
 
    Westpac will give, or has given, certain representations and warranties that
the Housing Loans and related Mortgages comply in all material respects with the
Consumer Credit Legislation in force at the time documents were entered into.
The Servicer has undertaken to comply with the Consumer Credit Legislation in
connection with servicing the Housing Loans and related Mortgages where failure
to do so would have an Adverse Effect. An "Adverse Effect" is an event which
will materially and adversely affect the amount of any payment to be made to any
Noteholder, or will materially and adversely affect the timing of such payment.
In certain circumstances the Issuer Trustee may have the right to claim damages
from Westpac or the Servicer, as the case may be, where the Issuer Trustee
suffers loss in connection with a breach of the Consumer Credit Legislation
which is caused by a breach of a relevant representation or undertaking.

BANKRUPTCY
 
    The insolvency of a natural person is governed by the provisions of the
Bankruptcy Act 1966, which is a federal statute. Generally, secured creditors of
a natural person (such as mortgagees under real property mortgages) stand
outside the bankruptcy--that is, the property of the bankrupt which is available
for distribution by the trustee in bankruptcy does not include the secured
property. The secured creditor may, if it wishes, prove in the bankruptcy
proceeding as an unsecured creditor in a number of circumstances, including if
they have realized the related mortgaged property and their debt has not been
fully repaid (in which case they can prove for the unpaid balance).
 
    Certain dispositions of property by a bankrupt may be avoided by the trustee
in bankruptcy. These include where (a) the disposition was made to defraud
creditors; or (b) the disposition was made by an insolvent debtor within 6
months of the petition for bankruptcy and gave a preference to an existing
creditor over at least one other creditor.
 
    The insolvency of a company is governed by the Corporations Law of the
relevant Australian jurisdiction. Again, secured creditors generally stand
outside the insolvency. However, a liquidator may avoid a mortgage which is
voidable under the Corporations Law because it is an uncommercial transaction,
or an unfair preference to a creditor or a transaction for the purpose of
defeating creditors, and that transaction occurred when the company was
insolvent (or an act is done to give effect to the transaction when the company
is insolvent, or the company becomes insolvent because of the transaction or the
doing of an act to give effect to the transaction), and the transaction occurred
within a prescribed period prior to the commencement of the winding up of the
company. The liquidator may also avoid a loan under which an extortionate
interest rate is levied.
 
ENVIRONMENTAL
 
    Real property which is mortgaged to a lender may be subject to unforeseen
environmental problems, including land contamination. Environmental legislation
which deals with liability for such problems exists at both state and federal
levels, although the majority of relevant legislation is imposed by the states.
No Australian statute expressly imposes liability on "passive" lenders or
security holders for environmental matters, and some states expressly exclude
such liability. However, liability in respect of environmentally damaged land
(which liability may include the cost of rectifying the damage) may attach to a
person who is, for instance, an owner, occupier or person in control of the
relevant property. In some but not all states, lenders are expressly excluded
from the definitions of one or more of these categories.
 
    Merely holding security over property will not convert a lender into an
occupier. However, a lender or receiver who goes into possession of contaminated
mortgaged property or otherwise enforces its security may be liable as an
occupier.
 
    Some environmental legislation provides that security interests may be
created over contaminated or other affected property to secure payment of the
costs of any necessary rectification of the property. The security interests may
have priority over pre-existing mortgages.
 
INSOLVENCY CONSIDERATIONS
 
    The current transaction is designed to minimize insolvency risk. For
example, the equitable assignment of the Housing Loans by Westpac to the Issuer
Trustee should ensure that the Housing Loans are not assets available to the
liquidator or creditors of Westpac in the event of an insolvency of Westpac.
Similarly, the assets in the Trust should not be available to other creditors of
the Issuer Trustee in its personal capacity or as trustee of any other trust in
the event of an insolvency of the Issuer Trustee.
 
    If any Insolvency Event occurs with respect to the Issuer Trustee, the
Security Trust Deed may be enforced by the Security Trustee at the direction of
the Voting Mortgagees (see "SECURITY FOR THE
 
                                      140
<PAGE>
NOTES--Enforcement"). The security created by the Security Trust Deed will stand
outside any liquidation of the Issuer Trustee, and the assets the subject of
that security will not be available to the liquidator or any creditor of the
Issuer Trustee (other than a creditor which has the benefit of the Security
Trust Deed) in priority to the Security Trust Deed. The proceeds of enforcement
of the Security Trust Deed are to be applied by the Security Trustee as set out
in "SECURITY FOR THE NOTES--Priorities under the Security Trust Deed". If the
proceeds from enforcement of the Security Trust Deed are not sufficient to
redeem the Notes in full, some or all of the Noteholders will incur a loss.
 
TREATMENT OF INTEREST PAYMENTS WITH RESPECT TO AUSTRALIAN HOUSING LOANS
 
    Under Australian law, interest on loans used to purchase a person's primary
place of residence is not ordinarily deductible for taxation purposes.
Conversely, interest payments on mortgage loans and other non-capital
expenditures relating to investment properties that generate taxable income are
generally allowable as tax deductions.
 
                                USE OF PROCEEDS
 
   
    The net proceeds from the sale of the Offered Notes will amount to       and
will be used by the Issuer Trustee to acquire equitable title to the Housing
Loans and related Mortgages from the Approved Sellers and for general expenses
(including any premium payable to any Swap Provider) in relation to the Trust.
    
 
                 UNITED STATES FEDERAL INCOME TAX CONSEQUENCES
 
    The following is a general discussion of the anticipated material United
States federal income tax consequences of the purchase, ownership and
disposition of Notes by Noteholders who are subject to United States federal
income tax. The summary is based on laws, regulations, rulings and decisions now
in effect, all of which are subject to change (possibly with retroactive effect)
or to different interpretation. The summary does not purport to address federal
income tax consequences applicable to particular categories of investors, some
of which (for example, insurance companies, dealers in securities, financial
institutions or foreign investors) may be subject to special rules. In addition,
this summary is generally limited to investors who will hold the Notes as
"capital assets" (generally, property held for investment) within the meaning of
Section 1221 of the Internal Revenue Code of 1986, as amended (the "Code").
Investors are urged to consult their own tax advisors with regard to the
application of the tax considerations discussed below to their particular
situations, as well as the consequences to them under, state, local, non-United
States and any other tax law of the purchase, ownership and disposition of
Notes, including the advisability of making any election discussed below.
Prospective investors should note that no rulings have been or will be sought
from the Internal Revenue Service (the "IRS" or the "Service") with respect to
any of the federal income tax consequences discussed below, and no assurance can
be given that the IRS will not take contrary positions. It is anticipated that
the Issuer Trustee will not be indemnified for any United States federal income
taxes that may be imposed upon it, and the imposition of any such taxes on the
Trust could result in a reduction in the amounts available for distribution to
the Noteholders.
 
    In the opinion of Mayer, Brown & Platt, tax counsel to the Issuer Trustee
("Tax Counsel"), for United States federal income tax purposes, the Notes will
be characterized as debt of the Issuer Trustee. Each Noteholder, by the
acceptance of a Note, will agree to treat the Notes as indebtedness for federal
income tax purposes.
 
GENERAL
 
    Each Noteholder will be required to report on its federal income tax return
interest income on Notes held by it in accordance with such Noteholder's method
of accounting.
 
                                      141
<PAGE>
SALES OF NOTES
 
    A Noteholder's tax basis in a Note will equal its cost of such Note, reduced
by any amortized premium (as described below) and any payments other than
interest made on such Note and increased by any market discount or original
issue discount included in the Noteholder's income. A Noteholder that sells a
Note will recognize gain or loss (in the aggregate) in an amount equal to the
difference between its adjusted tax basis in the Note and the amount realized on
the sale (except to the extent attributable to accrued interest, which should be
taxable as interest income). Subject to the market discount provisions of the
Code (described below), any such gain or loss will be capital gain or loss if
the Note was held as a capital asset and, if the Note was held for more than one
year, will be long-term capital gain or loss. In the case of an individual
taxpayer, any capital gain on the sale of a Note will be taxed at a maximum rate
of 39.6% if the Note is held for not more than 12 months, at 28% if the Note is
held for more than 12 months, but not more than 18 months, and at 20% if the
Note is held for more than 18 months. Any capital losses realized will be
deductible by a corporate taxpayer only to the extent of capital gains and by an
individual taxpayer only to the extent of capital gains plus U.S. $3,000 of
other income.
 
MARKET DISCOUNT
 
    A purchaser of a Note will be considered to have acquired such Note at a
"market discount" to the extent the remaining principal amount of such Note
exceeds the Noteholder's tax basis in such Note, unless the excess does not
exceed a prescribed DE MINIMIS amount. In the event such excess exceeds the de
minimis amount, the Noteholder will be subject to the market discount rules of
Sections 1276 and 1278 of the Code with regard to such Note.
 
    In the case of a sale or other disposition of a Note subject to the market
discount rules, Section 1276 of the Code requires that gain, if any, from such
sale or disposition be treated as ordinary income to the extent such gain
represents market discount that has accrued during the period in which the Note
was held by such Noteholder. In addition, a disposition of a Note by gift (and
in certain other circumstances), could result in the recognition of market
discount income, computed as if such Note had been sold for its fair market
value.
 
    In the case of a partial principal payment on a Note subject to the market
discount rules, Section 1276 of the Code requires that such payment be included
in gross income as ordinary income to the extent such payment does not exceed
the market discount that has accrued during the period such Note was held by
such Noteholder. The amount of any accrued market discount later required to be
included in income upon a disposition, or subsequent partial principal payment,
will be reduced by the amount of accrued market discount previously included in
income.
 
    Generally, market discount accrues under a straight line method, or, at the
election of the taxpayer, under a constant interest rate method. However, in the
case of bonds the principal of which may be paid in two or more installments
(such as the Notes), the manner in which market discount is to be accrued will
be described in Treasury regulations that have yet to be issued. Until such
Treasury regulations are issued, the explanatory conference committee Report to
the Tax Reform Act of 1986 (the "Conference Report") indicates that holders of
such obligations may elect to accrue market discount either on the basis of a
constant interest rate or as follows: (1) for those obligations that have
original issue discount ("OID"), market discount shall be deemed to accrue in
proportion to the accrual of OID for any accrual period, and (2) for those
obligations which do not have OID, the amount of market discount that is deemed
to accrue is the amount of market discount that bears the same ratio to the
total amount of remaining market discount that the amount of stated interest
paid in the accrual period bears to the total amount of stated interest
remaining to be paid on the obligation as of the beginning of such period.
 
    Under Section 1277 of the Code, if in any taxable year interest paid or
accrued by a Noteholder on indebtedness incurred or continued to purchase or
carry a Note subject to the market discount rules exceeds the interest
(including OID) currently includible in income with respect to such Note,
 
                                      142
<PAGE>
deductions of such interest must be deferred to extent of the market discount
allocable to the taxable year. The deferred portion of any interest expense will
generally be deductible when such market discount is included in income upon the
sale or other disposition (including repayment) of the indebtedness.
 
    Section 1278 of the Code allows a taxpayer to make an election to include
market discount in its gross income currently. If such election is made, the
rules of Sections 1276 and 1277 of the Code (described above) will not apply to
the taxpayer.
 
    Due to the complexity of the market discount rules, prospective Noteholders
are urged to consult their tax advisors as to the applicability and operation of
the market discount rules.
 
PREMIUM
 
    A Noteholder will generally be considered to have acquired a Note at a
premium to the extent the Noteholder's tax basis in such Note exceeds the
remaining principal amount of such Note. In that event, a Noteholder who holds a
Note as a capital asset may amortize the premium as an offset to interest income
under Section 171 of the Code, with corresponding reductions in the Noteholder's
tax basis in the Note if an election under Section 171 of the Code is or has
been made with respect to all debt instruments held by the taxpayer (including
the Notes). Generally, such amortization is on a constant yield basis. However,
in the case of bonds the principal of which may be paid in two or more
installments (such as the Notes), the Conference Report indicates a
Congressional intent that amortization will be in accordance with the same rules
that will apply to the accrual of market discount on such obligations (see the
discussion of market discount above).
 
BACKUP WITHHOLDING
 
    A Noteholder may be subject, under certain circumstances, to backup
withholding at a 31% rate with respect to "reportable payments" on the
Securities. This withholding generally applies only if the Noteholder (i) fails
to provide the Noteholder's social security or other taxpayer identification
number ("TIN"); (ii) furnishes an incorrect TIN; (iii) is notified by the
Service that the Noteholder has failed to report properly payments of interest
and dividends and the Service has notified the Issuer Trustee that the
Noteholder is subject to backup withholding; or (iv) fails, under certain
circumstances, to provide a certified statement, signed under penalty of
perjury, that the TIN provided is the Noteholder's correct number and that the
Noteholder is not subject to backup withholding. Any amount withheld from
payment to a Noteholder under the backup withholding rules is allowable as a
credit against such Noteholder's federal income tax liability, provided that the
required information is furnished to the Service. Certain Noteholders
(including, among others, corporations and foreign individuals who comply with
certain certification requirements) are not subject to backup withholding.
Noteholders should consult their tax advisors as to their qualifications for
exemption from backup withholding and the procedure for obtaining such an
exemption.
 
    ALL INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE FEDERAL,
STATE, LOCAL OR FOREIGN INCOME TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND
DISPOSITION OF THE NOTES.
 
                         CERTAIN AUSTRALIAN TAX MATTERS
 
    THE FOLLOWING STATEMENTS WITH RESPECT TO AUSTRALIAN TAXATION ARE ONLY
GENERAL SUMMARIES AND ARE BASED ON ADVICE RECEIVED BY THE ISSUER TRUSTEE.
PURCHASERS OF OFFERED NOTES SHOULD CONSULT THEIR OWN TAX ADVISERS CONCERNING THE
CONSEQUENCES, IN THEIR PARTICULAR CIRCUMSTANCES, UNDER AUSTRALIAN TAX LAWS, AND
THE LAWS OF ANY OTHER TAXING JURISDICTION, OF THE OWNERSHIP OF OR ANY DEALING IN
THE NOTES. ANY SUCH DEALING WOULD NEED TO COMPLY WITH THE SELLING RESTRICTIONS
AND SECURITIES LAW GENERALLY.
 
                                      143
<PAGE>
PAYMENTS OF PRINCIPAL, PREMIUMS AND INTEREST
 
    Under existing Australian tax law, non-resident holders of Notes or
interests in any Global Note (other than persons holding such securities or
interest as part of a business carried on, at or through a permanent
establishment in Australia (an "Australian Establishment")) are not subject to
Australian income tax on payments of interest or amounts in the nature of
interest, other than interest withholding tax. Under Article 11 of the 1983
United States-Australia Tax Convention, the maximum Australian withholding rate
on interest paid to United States recipients is 10%. Under Australian law, the
withholding rates for payments to other jurisdictions is currently 10% on
interest or amounts in the nature of interest paid on the Notes. A premium on
redemption would generally be treated as an amount in the nature of interest for
this purpose.
 
    Pursuant to section 128F of the Australian Income Tax Assessment Act 1936
(the "Tax Act"), an exemption from Australian interest withholding tax applies
provided all prescribed conditions are met. Such conditions include the issue of
the Offered Notes in a way that satisfies an objective public offer test. The
Issuer Trustee will seek to issue the Offered Notes in a way that will satisfy
such test and otherwise meet the requirements of section 128F including by
listing the Offered Notes.
 
    The test will not be satisfied if the Issuer Trustee knew, or had reasonable
grounds to suspect, that the Offered Notes were being or would later be acquired
either directly or indirectly by:
 
   
    (1) a resident of Australia for the purpose of section 128F of the Tax Act;
       or
    
 
   
    (2) an associate of the Issuer Trustee within the meaning of section 128F of
       the Tax Act, other than in the capacity of a dealer, manager or
       underwriter in relation to the placement of an Offered Note.
    
 
    The exemption from Australian withholding tax will also not apply to
interest paid by the Issuer Trustee to an associate of the Issuer Trustee within
the meaning of section 128F if, at the time of the payment, the Issuer Trustee
knows, or has reasonable grounds to suspect, that the person is an associate.
 
   
    In a press release of the Federal Government of Australia late last year
entitled Investing for Growth, it was announced that "in order to encourage the
deepening and greater liquidity of the domestic corporate debt market, the
interest withholding tax exemption provided under section 128F of the Income Tax
Assessment Act 1936 will be widened by removing, for eligible debentures issued
by companies, the present requirement that such debentures be issued outside
Australia and that the interest be paid outside Australia...this measure will
remove tax discrimination in favor corporate debt issued and foreign financial
markets over corporate debt issued in Australia markets."
    
 
   
    This amendment has not yet been enacted, therefore the effect, form and
timing of the proposed amendments are currently unclear.
    
 
PROFIT ON SALE
 
    Under existing Australian law, non-resident holders of Offered Notes will
not be subject to Australian income tax on profits derived from the sale or
disposal of the Offered Notes provided that:
 
    (1) the Offered Notes are not held as part of an Australian Establishment;
       and
 
   
    (2) the profits do not have an Australian source.
    
 
   
    The source of any profit on the disposal of Offered Notes will depend on the
factual circumstances of the actual disposal. Where the Offered Notes are
acquired and disposed of pursuant to contractual arrangements entered into and
concluded outside Australia, and the seller and the purchaser are non-residents
of Australia and do not have an Australian Establishment, the profit should not
have an Australian source. There are, however, specific withholding tax rules
that can apply to treat a portion of the sale price of Notes as interest for
withholding tax purposes (and which amounts are not covered by the exemption
conditions in section 128F). These rules can apply when:
    
 
    (1) Offered Notes are sold for an amount in excess of their issue price
prior to maturity; or
 
    (2) Offered Notes are sold to an Australian resident in connection with a
"washing arrangement" (as defined in the Tax Act).
 
                                      144
<PAGE>
OTHER TAXES
 
    No stamp, issue, registration or similar taxes are payable in Australia in
connection with the issue of the Offered Notes. Furthermore, a transfer of, or
agreement to transfer, Offered Notes executed outside of Australia will not be
subject to Australian stamp duty.
 
                              ERISA CONSIDERATIONS
 
    Subject to the considerations discussed below, the Offered Notes are
eligible for purchase by employee benefit plans.
 
    Section 406 of the Employee Retirement Income Security Act ("ERISA"), and/or
Section 4975 of the Code, prohibits a pension, profit-sharing or other employee
benefit plan, as well as individual retirement accounts and certain types of
Keogh Plans (each a "Benefit Plan") from engaging in certain transactions with
persons that are "parties in interest" under ERISA or "disqualified persons"
under the Code with respect to such Benefit Plan. A violation of these
"prohibited transaction" rules may result in an excise tax or other penalties
and liabilities under ERISA and the Code for such persons. Title I of ERISA also
requires that fiduciaries of a Benefit Plan subject to ERISA make investments
that are prudent, diversified (except if prudent not to do so) and in accordance
with governing plan documents.
 
   
    Certain transactions involving the purchase, holding or transfer of the
Notes might be deemed to constitute prohibited transactions under ERISA and the
Code if assets of the Issuer Trustee were deemed to be assets of a Benefit Plan.
Under a regulation issued by the United States Department of Labor (the "Plan
Assets Regulation"), the assets of the Issuer Trustee would be treated as plan
assets of a Benefit Plan for the purposes of ERISA and the Code only if the
Benefit Plan acquires an "equity interest" in the Issuer Trustee and none of the
exceptions contained in the Plan Assets Regulation is applicable. An equity
interest is defined under the Plan Assets Regulation as an interest in an entity
other than an instrument which is treated as indebtedness under applicable local
law and which has no substantial equity features. Although there can be no
assurances in this regard, it appears that the Notes should be treated as debt
without substantial equity features for purposes of the Plan Assets Regulation
and that the Notes do not constitute equity interests in the Issuer Trustee for
purposes of the Plan Assets Regulation. However, without regard to whether the
Notes are treated as an equity interest for such purposes, the acquisition or
holding of Notes by or on behalf of a Benefit Plan could be considered to give
rise to a prohibited transaction if the Issuer Trustee, or any of their
respective affiliates is or becomes a party in interest or a disqualified person
with respect to such Benefit Plan. In such case, certain exemptions from the
prohibited transaction rules could be applicable depending on the type and
circumstances of the plan fiduciary making the decision to acquire a Note.
Included among these exemptions are: Prohibited Transaction Class Exemption
("PTCE") 96-23, regarding transactions effected by "in-house asset managers";
PTCE 90-1, regarding investments by insurance company pooled separate accounts;
PTCE 95-60, regarding transactions effected by "insurance company general
accounts"; PTCE 91-38, regarding investments by bank collective investment
funds; and PTCE 84-14, regarding transactions effected by "qualified
professional asset managers." By its acquisition of a Note, each purchaser shall
be deemed to represent and warrant that its purchase and holding of the Note
will not result in a non-exempt prohibited transaction under ERISA or the Code.
    
 
    Employee benefit plans that are governmental plans (as defined in Section
3(32) of ERISA) and certain church plans (as defined in Section 3(33) of ERISA)
are not subject to ERISA requirements.
 
    A PLAN FIDUCIARY CONSIDERING THE PURCHASE OF ANY OF THE NOTES SHOULD CONSULT
ITS TAX AND/OR LEGAL ADVISORS REGARDING WHETHER THE ASSETS OF THE ISSUER TRUSTEE
WOULD BE CONSIDERED PLAN ASSETS, THE POSSIBILITY OF EXEMPTIVE RELIEF FROM THE
PROHIBITED TRANSACTION RULES AND OTHER ISSUES AND THEIR POTENTIAL CONSEQUENCES.

<PAGE>
                              RATINGS OF THE NOTES
 
   
    It is a condition to the issuance of the Class A Notes that they be rated
"AAA" by Standard & Poor's Ratings Group, a division of The McGraw-Hill
Companies ("Standard & Poor's"), "Aaa" by Moody's Investors Service, Inc.
("Moody's") and "AAA" by Fitch IBCA, Inc. ("Fitch" and together with Standard &
Poor's, the "Rating Agencies"). It is a condition to the issuance of the Class B
Notes that they be rated "AA-" by Standard & Poor's and "AA-" by Fitch. The
security ratings of the Offered Notes should be evaluated independently from
similar ratings on other types of securities. A security rating is not a
recommendation to buy, sell or hold securities and may be subject to revision or
withdrawal at any time by the Rating Agencies.
    
 
                        LEGAL INVESTMENT CONSIDERATIONS
 
   
    The Offered Notes will not constitute "mortgage related securities" for
purposes of the Secondary Mortgage Market Enhancement Act of 1984 ("SMMEA"),
because the originator of the Mortgage Loans was not subject to United States
State of Federal regulatory authority. Accordingly, many institutions with legal
authority to invest in comparably rated securities based on such mortgage loans
may not be legally authorized to invest in the Offered Notes, which, for the
reasons stated herein, do not constitute "mortgage related securities" under
SMMEA. No representation is made as to whether the Offered Notes constitute
legal investments under any applicable statute, law, rule, regulation or order
for any entity whose investment activities are subject to investment laws and
regulations or to review by certain regulatory authorities. Prospective
purchasers are urged to consult with their counsel concerning the status of the
Offered Notes as legal investments for such purchasers.

    The Underwriters have entered into the Underwriting Agreement with the
Issuer Trustee.
 
    In the Underwriting Agreement, the Underwriters named therein have agreed,
subject to the terms and conditions set forth therein, to purchase all of the
Offered Notes offered hereby if any Offered Notes are purchased. In the event of
default by an Underwriter, the Underwriting Agreement provides that, in certain
circumstances, the Underwriting Agreement may be terminated.
 
    The Issuer Trustee has been advised by the Underwriters that they propose
initially to offer the Offered Notes to the public at the respective offering
prices set forth on the cover page hereof and to certain dealers at such prices
less concessions not to exceed    % of the Class A Principal Balance and    % of
the Class B Principal Balance.
 
    With respect to the Class A Notes, the Underwriters may allow and such
dealers may reallow, a concession not to exceed    % of the aggregate of the
Class A Principal Balance. With respect to the Class B Notes, the Underwriters
may allow and such dealers may reallow, a concession not to exceed    % of the
Class B Principal Balance.

    In connection with the offering, the Underwriters may engage in transactions

                 APPENDIX I--GLOSSARY OF AUSTRALIAN LEGAL TERMS
 
    "CHARGE" means the charge created by the Security Trust Deed. A Charge is a
proprietary interest created over property.
 
    "CHARGOR"  means the person or entity granting a Charge.
 
    MORTGAGEE IN POSSESSION ("MIP")  means a mortgagee in possession of the
related Mortgaged Property who, following an enforcement of the relevant
mortgage, is able to deal with the Mortgaged Property without becoming the
absolute owner of the Mortgaged Property.
 
   
    "REGISTERED"  means the mortgage has been filed with lands office in the
relevant Australian State or Territory, granting certain rights with respect to
the applicable Mortgaged Property.
    
 
    "SECURED MONEYS"  means all money which the Issuer Trustee (whether alone or
with another person) is or at any time may become actually or contingently
liable to pay to or for the account of any Mortgagee (whether alone or with
another person) for any reason whatever under or in connection with a Trust
Document.
 
   
    "STRATA TITLE"  means a system of title in which the relevant land is
divided into the relevant number of units. Each proprietor has title to, and may
freely dispose of, their unit. All proprietors are members of a "body
corporate", which monitors compliance with rules governing the apartment block.
Certain parts of the property, such as stairwells, entrance lobbies and the like
are known as "common property" and are owned by the body corporate as a whole
rather than by individual proprietors.
    
 
   
    "TORRENS TITLE"  means a system of title in which the relevant land is
freehold title, interests in which are created by registration in a central land
registry of the relevant State or Territory. Each parcel of land is represented
by a specific certificate of title. The original certificate is retained by the
registry, and in most States a duplicate certificate is issued to the owner. Any
dealing with the relevant land is carried out by pro forma instruments which
become effective on registration.

ITEM 17. UNDERTAKINGS.
 
    The undersigned Registrant on behalf of the Westpac Securitization Trust,
Series 1998-1G (the "Trust") hereby undertakes:
 
        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this registration statement;
 
            (i) To include any prospectus required by Section 10(a)(3) of the
       Securities Act of 1933, as amended (the "Act");
 
            (ii) To reflect in the prospectus any facts or events arising after
       the effective date of the registration statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the registration statement;
 
           (iii) To include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement or
       any material change to such information in the registration statement.
 
        (2) That, for the purpose of determining any liability under the Act,
    each post-effective amendment that contains a form of prospectus shall be
    deemed to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial bona fide offering thereof.
 
        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.
 
        (4) To file a post-effective amendment to the registration statement to
    include any financial statements required by Rule 3-19 at the start of any
    delayed offering or throughout a continuous offering.
 
    Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the Registrant
pursuant to the foregoing provisions, or otherwise, the Registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

    For purposes of determining any liability under the Securities Act of 1933,
the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.
 
    For the purposes of determining any liability under the Securities Act of
1933, each post-effective amendment that contains a form of prospectus shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

                  present may demand a poll.

         (4)      The rights conferred on the holders of the shares of any class
                  issued with preferred or other special rights shall not,

                  conversion of existing securities to securities ranking in

                  (a)   in respect of any shares registered in the name of a
                        member (whether solely or jointly with others); or

                  (b)   in respect of any Dividends, interest, bonuses or

                  to pay any amount for or on account or in respect of any

                  (a)   shall be fully indemnified by the member referred to in
                        paragraph (5) or the member's estate from and against

                        of that member for all moneys paid or payable by the
                        company in respect of those shares under or in
                        consequence of the liability; and

                  shares.

         (2)      The company shall register the purchaser as the holder of the
                  shares comprised in any transfer, after which the validity of
                  the sale may not be impeached by any person, and the purchaser
                  is not bound to see to the application of the purchase money.

         (3)      The title of the purchaser to the shares is not affected by
                  any irregularity or invalidity in connection with the sale.

         (6)     The non-receipt of a notice of a call by, or the accidental
                 omission to give notice of a call to, any member shall not
                 invalidate the call.

                  pay interest on the sum from the day appointed for payment of
                  the sum to the time of actual payment at a rate determined by
                  the directors but not exceeding the Prescribed Rate together

                  payable on allotment or at a fixed date (whether on account of
                  the nominal amount of the share or by way of premium) shall,
                  for the purposes of these Articles, be taken to be a call duly
                  made and payable on the date on which under the terms of issue
                  the sum becomes payable.

         (2)      If any other sum is not paid when due, all the provisions of
                  these Articles relating to payment of interest and expenses,

                  exceeding the Prescribed Rate, which is agreed between the
                  directors and the member paying the sum.

         (3)      The directors may at any time repay the whole or any part of
                  any amount paid in advance on serving the member with one

                  think fit.

                  This Article does not release the estate of a deceased joint
                  holder from any liability in respect of a share that had been
                  jointly held by the holder with other persons.

                  shares are applicable to any transfer as if the death or
                  bankruptcy of the member had not occurred and the notice or
                  transfer were a transfer signed by that member.

32.      DIVIDENDS AND OTHER RIGHTS

         (1)      Where a member dies or becomes bankrupt, the member's legal

                  same rights (whether in relation to meetings of the company or
                  to voting or otherwise) as the member would have been entitled
                  to if the member had not died or become bankrupt.

         (2)      Where 2 or more persons are jointly entitled to any share as a
                  result of the death of a member, they shall, for the purposes
                  of these Articles, be taken to be joint holders of the share.

                  any part of the call or instalment remains unpaid, serve a
                  notice on the member requiring payment of so much of the call
                  or instalment as is unpaid, together with any interest that
                  has accrued and all expenses of the company incurred as a

                        place at which the payment required by the notice is to
                        be made; and

                  (b)   state that, if payment is not made at or before the time
                        specified, the shares in respect of which the call was

         (1)      If the requirements of a notice served under Article 33 are
                  not complied with, any share in respect of which the notice
                  has been given may at any time afterwards, but before the
                  payment required by the notice has been made, be forfeited by
                  a resolution of the directors to that effect.

         (2)      Such a forfeiture shall include all Dividends declared in
                  respect of the forfeited shares and not actually paid before
                  the forfeiture.

                  (b)   shall have no claims or demands against the company in
                        respect of those shares;

                        the rights that are expressly provided by the Law or

                        directors think fit, interest from the date of
                        forfeiture at the Prescribed Rate on the money for the
                        time being unpaid). The directors may (but shall not be
                        obliged to) enforce the payment of the money or any part
                        of the money for which the member is liable as they
                        think fit.

                  date shall be made immediately in the register.

         (2)      The provisions of paragraph (1) are directory only and the
                  validity of any forfeiture shall not be affected in any way by
                  any omission to give the notice or to note the entry.

                  (a)   a share in the company has been duly forfeited on a date
                        specified in the statement; or

                  (b)   a particular sum is payable by a member or former member
                        to the company as at a particular date in respect of a
                        call or instalment of a call (including interest),

         the member or former member who remains liable to the company under
         Article 37.

40.      TRANSFERS AFTER FORFEITURE AND SALE

         (1)      The company may:

                  (a)   receive the consideration (if any) given for a forfeited
                        share on any sale or disposition of the share; and

                  (b)   effect a transfer of the share in favour of the person

         (3)      The title of the transferee to the share is not affected by

         share, becomes payable at a fixed time, whether on account of the
         nominal amount of the share or by way of premium, as if that sum had
         become payable by virtue of a call duly made.

                  (b)   reconvert or provide for the reconversion of that stock
                        into paid up shares of any denomination.

                  into stock, the provisions of these Articles relating to the
                  transfer of shares apply, so far as they are capable of
                  application, to the transfer of the stock or any part of the
                  stock.

         (2)      The directors may fix the minimum amount of stock transferable
                  and restrict or forbid the transfer of fractions of that

                  nominal amount of the shares from which the stock arose.

44.      RIGHTS AND PRIVILEGES OF MEMBERS

         (1)      The holders of stock have, according to the amount of the
                  stock held by them, the same rights, privileges and advantages
                  as regards Dividends, voting at meetings of the company and
                  other matters as they would have if they held the shares from
                  which the stock arose.

         (2)      No such right, privilege or advantage (except participation in
                  the Dividends and profits of the company and in the property
                  of the company on winding up) shall be conferred by any amount
                  of stock that would not, if existing in shares, have conferred
                  that right, privilege or advantage.

45.      INTERPRETATION

         The provisions of these Articles that are applicable to paid up shares
         apply to stock and references in those provisions to share and member

                        shares of such amount as it thinks expedient;

                  (b)   by consolidating and dividing all or any of its share
                        capital into shares of a larger amount than its existing
                        shares;

                  (c)   by subdividing all or any of its shares into shares of
                        smaller amount than is fixed by the memorandum, but so
                        that, in the subdivision, the proportion between the
                        amount paid and the amount (if any) unpaid on each share
                        of a smaller amount is the same as it was in the case of
                        the share from which the share of a smaller amount is
                        derived; and

                  (d)   by cancelling shares that, at the date of the passing of
                        the resolution to that effect, have not been taken or

                  indicated.

65.      LODGMENT OF PROXIES

         (1)      An instrument appointing a proxy shall not be treated as valid

                          (i)       the power of attorney or other authority (if
                                    any) under which he instrument is signed; or

                          (ii)      a copy of that power or authority certified
                                    in a manner acceptable to the directors,

                  and a declaration or statement by the proxy of the
                  non-revocation of that power or authority are lodged at any
                  time before commencement of the meeting or adjourned meeting
                  at which the person named in the instrument proposes to vote,
                  at the place which is specified for that purpose in the notice
                  convening the relevant meeting or, if none, at the registered
                  office of the company or the place where the meeting is held.

         (2)      An instrument appointing an attorney to act on behalf of a
                  member at all meetings of the company or at all meetings for a
                  specified period shall not be treated as valid unless:

                  (a)   the power of attorney or a certified copy of that power
                        of attorney; and

                  (b)   any evidence that the directors may require of the
                        validity and non-revocation of that power of attorney,

                  adjourned meeting at which the attorney proposes to vote at
                  the place which is specified for that purpose in the notice

                  have been duly lodged at that place at the time when the
                  facsimile is received.

66.      VALIDITY OF PROXIES

         A vote exercised in accordance with the terms of an instrument of
         proxy, a power of attorney or other relevant instrument of appointment
         is valid despite:

                  (a)   the previous death or unsoundness of mind of the
                        principal;

                  (b)   the revocation of the instrument (or of the authority
                        under which the instrument was executed) or the power;
                        or

                  (c)   the transfer of the share in respect of which the
                        instrument or power is given,

         if no notice in writing of the death, unsoundness of mind, revocation
         or transfer has been received by the company at its registered office
         at least 24 hours (or any shorter period as the directors may permit)
         before the commencement of the meeting or adjourned meeting at which
         the instrument is used or the power is exercised.

67.      WHERE PROXY IS INCOMPLETE

         (1)      No instrument appointing a proxy shall be treated as invalid
                  merely because:

                  (a)   it does not contain the address of the appointor or of a
                        proxy;

                  (b)   it is not dated; or

                  (c)   it does not contain in relation to any or all
                        resolutions, an indication of the manner in which the
                        proxy is to vote.

         (2)      Where the instrument does not specify the name of a proxy, the
                  instrument shall be taken to be given in favour of the
                  chairman of the meeting.


68.      RIGHT OF OFFICERS AND ADVISORS TO ATTEND GENERAL MEETING

                  that general meeting.

69.      SINGLE MEMBER RESOLUTIONS

                  value to the company of the extra services or special

                            PROCEEDINGS OF DIRECTORS

78.      PROCEEDINGS

         (1)      The directors may meet together for the despatch of business
                  and adjourn and otherwise regulate their meetings as they
                  think fit.

         (2)      A director may at any time, and on the request of a director a

         (3)      Reasonable notice must be given to every director of the
                  place, date and time of every meeting of the directors. Where
                  any director is for the time being outside of Australia,
                  notice need only be given to that director if contact details
                  have been given, but notice shall always be given to any

                        of the directors, be taken to be assembled together at
                        a meeting and to be present at that meeting; and

                  (b)   all proceedings of those directors conducted in that
                        manner shall be as valid and effective as if conducted
                        at a meeting at which all of them were present.

80.      QUORUM AT MEETINGS

         At a meeting of directors, the number of directors whose presence is
         necessary to constitute a quorum is the number determined by the
         directors and, if not so determined, is 2 directors entitled to vote.

81.      CHAIRMAN OF DIRECTORS

         (1)      The directors may elect one of their number as their chairman
                  and may decide the period for which the chairman is to hold
                  office as chairman.

         (2)       Where a meeting of directors is held and:

                  (a)   a chairman has not been elected as provided by paragraph
                        (1); or

                  (b)   the chairman is not present at the time appointed for
                        the holding of the meeting or does not wish to chair the
                        meeting,

                  the directors present shall elect one of their number to be a
                  chairman of the meeting.

<PAGE>
                                                                         Page 27


         (3)      The remuneration of the chairman from the remuneration fixed

82.      PROCEEDINGS AT MEETINGS

         (1)      Subject to these Articles, questions arising at a meeting of
                  directors shall be decided by a majority of votes of directors
                  present and voting and any such decision shall for all
                  purposes be taken to be a decision of the directors.

         (2)      In the case of an equality of votes, the chairman of the
                  meeting has a casting vote in addition to the chairman's
                  deliberative vote.


83.      DISCLOSURE OF INTERESTS

         (1)      A director is not disqualified by the director's office from
                  contracting with the company in any capacity.

         (2)      A contract or arrangement made by the company with a director
                  or in which a director is in any way directly or indirectly
                  interested shall not be avoided merely because the director is
                  a party to or interested in it.

         (3)      A director is not liable to account to the company for any
                  profit derived in respect of a matter in which the director
                  has a material interest, merely because of the director's
                  office or the fiduciary relationship it entails, if the
                  director has:

                  (a)   declared the director's interest in the matter as soon
                        as practicable after the relevant facts have come to the
                        director's knowledge; and

                  (b)   not contravened these Articles or the Law in relation to
                        the matter.

                  A general notice that the director is an officer or member of
                  a specified body corporate or firm stating the nature and
                  extent of the director's interest in the body corporate or
                  firm shall, in relation to a matter involving the company and
                  that body corporate or firm, be a sufficient declaration of
                  the director's interest, provided the extent of that interest
                  is no greater at the time of first consideration of the
                  relevant matter by the directors than was stated in the
                  notice.

<PAGE>
                                                                         Page 28



         (4)      Subject to the Law, a director may vote in respect of a matter
                  in which that director has a material interest.

         (5)      If the provisions of this Article and the Law have been
                  observed by any director with regard to any contract or
                  arrangement in which the director is in any way interested,
                  the fact that the director affixed or witnessed the affixing
                  of a Seal to the document evidencing the contract or
                  arrangement shall not in any way affect its validity.

         (6)      A director may hold any office of employment or profit in the
                  company (other than auditor) in addition to holding office as
                  a director.

84.      ALTERNATE DIRECTORS

         (1)       A director may:

                  (a)   with the approval of a majority of the other directors
                        (if any), appoint a person (whether a member of the
                        company or not); or

                  (b)   without the need for the approval of the other
                        directors, appoint another director,

                  to be an alternate director in the director's place during any
                  period that the director thinks fit.

         (2)      An alternate director is entitled to notice of meetings of the
                  directors and, if the appointor is not present at such a
                  meeting, is entitled to attend and vote in the director's
                  stead.

         (3)      An alternate director may exercise any powers that the
                  appointor may exercise. The exercise of any power by the
                  alternate director (including affixing a Seal) shall be taken
                  to be the exercise of the power by the appointor. The exercise
                  of any power by the alternate director shall be as agent of
                  the company and not as agent of the appointor. Where the
                  alternate is another director, that director shall be entitled
                  to cast a deliberative vote on the director's own account and
                  on account of each person by whom the director has been
                  appointed as an alternate director.

         (4)       The appointment of an alternate director:

                  (a)   may be terminated at any time by the appointor even if
                        the period of the appointment of the alternate director
                        has not expired; and

                  (b)   terminates automatically if the appointor vacates office
                        as a director.

                                                                         Page 29


         (5)      An appointment or the termination of an appointment of an
                  alternate director shall be effected by service on the company
                  of a notice in writing signed by the director making the
                  appointment.

         (6)      The company shall not be responsible for remunerating the
                  alternate director.

         (7)      An alternate director shall be entitled to be reimbursed under
                  Article 72 as if the alternate director was a director.


85.      COMMITTEES

         (1)      The directors may delegate any of their powers to a committee
                  or committees consisting of such number of them and/or other
                  persons as they think fit. A committee may consist of one or
                  more persons.

         (2)      A committee to which any powers have been so delegated shall
                  exercise the powers delegated in accordance with any
                  directions of the directors. A power so exercised shall be
                  taken to have been exercised by the directors.

         (3)      Articles 78, 79, 81 (other than paragraph (3)) and 82 shall
                  apply to any committee as if each reference in those Articles
                  to the directors was a reference to the members of the
                  committee and each reference to a meeting of directors was to
                  a meeting of the committee.

         (4)      The number of members whose presence at a meeting of the
                  committee is necessary to constitute a quorum is the number
                  determined by the directors and, if not so determined, is 2.

         (5)      Subject to Article 87, minutes of all the proceedings and
                  decisions of every committee shall be made, entered and signed
                  in the same manner in all respects as minutes of proceedings
                  of the directors are required by the Law to be made, entered
                  and signed.

86.      WRITTEN RESOLUTIONS

         (1)      If a document:

                  (a)   contains a statement that the signatories to it are in
                        favour of a resolution;

                  (b)   the terms of the resolution are set out or identified in
                        the document; and

                  (c)   has been signed by a majority of the directors entitled
                        to vote on that resolution,

                  a resolution in those terms shall be taken to have been passed
                  at a meeting of the directors held on the day on which and at
                  the time at which the document was last signed by a director
                  and the document has effect as a minute of the resolution.

         (2)      For the purposes of paragraph (1):

                  (a)   2 or more separate documents containing statements in
                        identical terms each of which is signed by one or more
                        directors shall together be taken to constitute one
                        document containing a statement in those terms signed by

<PAGE>
                                                                         Page 30


                        those directors at the time at which the last of those
                        documents to be signed was signed by a director;

                  (b)   a reference to a majority of the directors does not
                        include a reference to an alternate director whose
                        appointor has signed the document, but an alternate
                        director may sign the document in the place of the

         only, a document signed by that person which records a decision of the
         person:

                  or a member of the committee.

         (2)      Paragraph (1) applies even if it is afterwards discovered that
                  there was some defect in the appointment of a person to be a
                  director or a member of a committee or to act as a director or
                  that a person so appointed was disqualified.

                        to be paid but otherwise be paid according to the
                        amounts paid or credited as paid on the shares in
                        respect of which it is to be paid; and

                  (c)   except where the resolution for the payment of the
                        dividend otherwise directs or in the case of any share
                        issued on terms providing that it will rank for dividend
                        as from a particular date, be apportioned and paid
                        proportionately to the amounts paid or credited as paid
                        on the shares in respect of which the dividend is to be
                        paid during any part or parts of the period in respect
                        of which the dividend is paid.

         (2)      An amount paid or credited as paid on a share in advance of a

                  the company any sums as they think proper as reserves which
                  shall, at the discretion of the directors, be applicable for
                  any purpose to which the profits of the company may be
                  properly applied.

         (2)      Pending any application under paragraph (1), the reserves may,
                  at the discretion of the directors, either be employed in the
                  business of the company or be invested in any investments as
                  the directors may from time to time think fit.

         (3)      The directors may, without placing them to reserve, carry
                  forward any profits which they may think prudent not to
                  divide.

                        for distribution of the specific assets or any part of
                        those assets;

                  (b)   decide that cash payments will be made to any members on
                        the basis of the value so fixed in order to adjust the
                        rights of all parties; or

                  (c)   vest any specific assets in trustees.

         (3)      Where the conditions of issue of a partly paid share so
                  provide, the holder shall be entitled to participate in any
                  application of a sum under paragraph (2) to a greater extent
                  than would have been the case had those funds been distributed
                  by Dividend but not to any greater extent than permitted by
                  the terms of issue.

         (4)      The directors shall do all things necessary to give effect to
                  the resolution and, in particular, to the extent necessary to
                  adjust the rights of the members among themselves, may:

                  (a)   fix the value for distribution of the specific assets or

                  (b)   issue fractional certificates or make cash payments in
                        cases where shares or debentures or debenture stock
                        become issuable in fractions or determine that fractions
                        may be disregarded;

                  (c)   vest any cash or specific assets in trustees on trust
                        for the persons entitled as they think fit; and

                  (d)   authorise any person to make, on behalf of all the
                        members entitled to any further shares or debentures or
                        debenture stock on the capitalization, an agreement with
                        the company providing for the issue to them, credited as
                        fully paid up, of any further shares or debentures or
                        debenture stock or for the payment by the company on
                        their behalf of the amounts or any part of the amounts
                        remaining unpaid on their existing shares by the
                        application of their respective proportions of the sum
                        resolved to be capitalized and any agreement made under
                        that authority is effective and binding on all the
                        members concerned.

                  (a)   establish one or more plans under which some or all
                        members may elect in terms of one or more of the
                        following for a period or periods as provided in the
                        plan:

                          (i)     that Dividends to be paid in respect of some
                                  or all of the shares from time to time held
                                  by the member shall be satisfied by the
                                  issue of fully paid ordinary shares;

                          (ii)    that Dividends shall not be declared or paid
                                  in respect of some or all of the shares from
                                  time to time held by the member, but that the
                                  member will receive an issue of fully paid
                                  ordinary shares paid up out of the company's
                                  share premium account; or

                  (b)   on or after establishment of any plan extend
                        participation in it, in whole or in part, to some or all
                        of the holders of debt obligations of the company in
                        respect of interest on such obligations in like manner
                        as if that interest were Dividends; and

                  (c)   vary, suspend or terminate the plan.

         (2)      Any such plan shall have effect in accordance with its terms
                  and the directors shall do all things necessary and convenient
                  for the purpose of implementing the plan, including the making
                  of each necessary allotment of shares and of each necessary
                  appropriation, capitalization, application, payment and
                  distribution of funds which may lawfully be appropriated,
                  capitalized, applied, paid or distributed for the purpose of
                  the allotment.

         (3)      For the purpose of giving effect to any such plan,
                  appropriations, capitalisation, applications, payments and
                  distributions as referred to in Article 103 may be made and
                  the powers of the directors under Article 103(4) shall apply
                  and may be exercised (with such adjustments as may be
                  required) even if only some of the members or holders of
                  shares of any class participate in the appropriations,
                  capitalization, application, payment or distribution.

         (4)      In offering opportunities to members to participate in any
                  such plan, the directors may give such information as in their
                  opinion may be useful to assist members in assessing the
                  opportunity and making requests to their best advantage. The
                  directors, the company and its officers shall not be
                  responsible for, nor shall they be obliged to provide, any
                  legal, taxation or financial advice in respect of the choices
                  available to members.

         (5)      The directors shall be under no obligation:

                  (a)   to admit any member as a participant in any such plan;
                        or

                  (b)   to comply with any request made by a member who is not
                        admitted as a participant in any such plan.

         (6)      In establishing and maintaining any such plan, the directors
                  shall act in accordance with the provisions of these Articles
                  and may exercise all or any of the powers conferred on them by
                  the terms of any such plan, by these Articles or by the Law.

                        dividends and the making of distributions in accordance
                        with Articles 101 and 103; and

                                   WINDING UP

108.     WINDING UP

         (1)      If the company is wound up and the assets available for
                  distribution among the members are insufficient to repay the
                  whole of the paid up capital, the assets shall be distributed
                  so that, as nearly as may be, the losses shall be borne by the
                  members in proportion to the capital paid up, or which ought
                  to have been paid up, at the commencement of the winding up,
                  on the shares held by them respectively.

         (2)      If, in a winding up, the assets available for distribution
                  among the members are more than sufficient to repay the whole
                  of the capital paid up at the commencement of the winding up,
                  the excess shall be distributed among the members in
                  proportion to the capital at the commencement of the winding
                  up paid up, or which ought to have been paid up, on the shares
                  held by them respectively.

         (3)      If the company is wound up, the liquidator may:

                  (a)   with the sanction of a special resolution, divide among
                        the members in kind the whole or any part of the
                        property of the company;

                  (b)   for that purpose set a value as the liquidator considers
                        fair on any property to be so divided; and

                  (c)   decide how the division is to be carried out as between
                        the members or different classes of members.

         (4)      The liquidator may, with the sanction of a special resolution,
                  vest the whole or any part of any property in trustees on any
                  trusts for the benefit of the contributories as the liquidator
                  thinks fit, but so that no member is compelled to accept any
                  shares or other securities in respect of which there is any
                  liability.

                                    INDEMNITY

109.     INDEMNITY AND INSURANCE

         (1)      To the extent permitted by law and without limiting the powers
                  of the company, the company must indemnify each person who is,
                  or has been, a director or secretary of the company against
                  any liability which results directly or indirectly from facts
                  or circumstances relating to the person serving or having
                  served in that capacity in relation to the company or any of
                  its subsidiaries or in the capacity of an employee of the
                  company or any of its subsidiaries:

                  (a)   to any person (other than the company or a related body
                        corporate), which does not arise out of conduct
                        involving a lack of good faith or conduct known to the
                        person to be wrongful;

                  (b)   for costs and expenses incurred by the person in
                        defending proceedings, whether civil or criminal, in
                        which judgment is given in favour of the person or in
                        which the person is acquitted, or in connection with any

                  application in relation to such proceedings in which the court
                  grants relief to the person under the Law.

         (2)      The company need not indemnify a person as provided for in
                  paragraph (1) in respect of a liability to the extent that the

                  employee or other officer of the company or of a subsidiary of
                  the company, which indemnity or insurance policy may be in
                  such terms as the board of directors approves and, in
                  particular, may apply to acts or omissions prior to or after
                  the time of entering into the indemnity or policy;

         (4)      The benefit of each indemnity given in paragraph (1)
                  continues, even after its terms or the terms of this paragraph
                  are modified or deleted, in respect of a liability arising out
                  of acts or omissions occurring prior to the modification or
                  deletion.

         (a)      a failure by an Obligor to pay any amount pursuant to the

         (b)      the Servicer fails to pay any amount in accordance with any

         (c)      the Servicer fails to comply with any of its other obligations
                  under any Transaction Document and such action has had, or, if
                  continued will have, an Adverse Effect (as determined by the
                  Trustee) and the Servicer does not remedy that failure within
                  30 days after the Servicer becomes aware of that failure by
                  receipt of a notice from either the Trustee or the Trust

         (d)      any representation, warranty or certification made by the

                  Eligible Servicer; and

                  under Clause 8.3.

1.2      Interpretation

         The provisions of clause 1.2 of the Master Trust Deed apply to this
         Agreement, as if set out in full, and on the basis that a reference in
         Clause 1.2(e) or (f) to "this Deed" is a reference to this Agreement.

1.3      Limitation of Trustee's Liability

         (a)      The Trustee enters into this Agreement only in its capacity
                  as trustee of each Relevant Trust and in no other capacity. A
                  liability arising under or in connection with this Agreement 
                  can be enforced against the Trustee only to the extent to 
                  which it can be satisfied out of property of the Relevant 
                  Trust out of which the Trustee is actually indemnified for 
                  the liability. This limitation of the Trustee's liability 
                  applies despite any other provision of this Agreement (other
                  than Clause 1.3(c)) and extends to all liabilities and 
                  obligations of the Trustee in any way connected with any
                  representation, warranty, conduct, omission, agreement or
                  transaction related to this Agreement.

         (b)      The parties other than the Trustee may not sue the Trustee
                  personally or seek the appointment of a liquidator, 
                  administrator, receiver or similar person to the Trustee or 
                  prove in any liquidation, administration or arrangement of or
                  affecting the Trustee.

         (c)      The provisions of this Clause 1.3 shall not apply to any 
                  obligation or liability of the Trustee to the extent that 
                  obligation or liability is not satisfied because:

                  (i)      under the trust deed establishing the Trust; or

                                                                         Page  4
- --------------------------------------------------------------------------------

                  (ii)     by operation of law,

                  there is a reduction in the extent, or extinguishment, of the
                  Trustee's indemnification out of the assets of the Relevant
                  Trust, as a result of the Trustee's fraud, negligence or
                  breach of trust.

         (d)      It is acknowledged that the Trust Manager of the Relevant
                  Trust is responsible under the Master Trust Deed for a variety
                  of obligations relating to the Trust, including under this
                  Agreement. No act or omission of the Trustee (including any
                  related failure to satisfy its obligations under this
                  agreement) will be considered fraud, negligence or breach of
                  trust of the Trustee for the purpose of Clause 1.3(c) to the
                  extent to which the act or omission was caused or contributed
                  to by any failure by the Trust Manager or the Servicer or any
                  other person properly appointed by the Trustee, the Trust
                  Manager or the Servicer to fulfil its obligations relating to
                  the Relevant Trust or by any other act or omission of the any
                  other person properly appointed by the Trustee, the Trust

         (e)      No attorney, agent, receiver or receiver and manager appointed
                  in accordance with this Agreement has authority to act on
                  behalf of the Trustee in a way which exposes the Trustee to
                  any personal liability and no act or omission of any such
                  person will be considered fraud, negligence or breach of trust
                  of the Trustee for the purpose of Clause 1.3(c).

         materially and adversely affect the amount of any payment to be made to
         any Noteholder, or will materially and adversely affect the timing of
         such payment):

         (a)      to waive any fees and break costs which may be collected in

                  default under any Receivables;

         (b)      in its discretion, to waive any right in respect of any

                  restriction on granting extensions that will not have an

                  relation to each Relevant Trust.


         (b)      Each Receivable will be electronically tagged so that all
                  related Collections and performance statistics (the nature of
                  which shall be as mutually agreed from time to time by the
                  Servicer, the Trust Manager and the Trustee) for that
                  Receivable can be readily identified.

2.5      Servicer's power to delegate

         Without in any way affecting the generality of the above, the Servicer
         may in carrying out and performing its duties and obligations contained
         in this Agreement:

         (b)      (appoint attorneys or subcontract) appoint any person to be
                  its attorney or agent or delegate to or subcontract with any

                  (i)      power for the attorney or agent to sub-delegate any
                           such powers, authorities or discretions;

                  (ii)     power to authorise the issue in the name of the
                           Servicer of documents bearing facsimile signatures of

                           of their officers); and

                  (iii)    provisions for the protection and convenience of
                           those dealing with any such attorney, agent or

         (c)      (suspend agents and sub-agents) supersede or suspend any such
                  attorney, agent or delegate for such cause or reason as the

                  without assigning any cause or reason and either absolutely or
                  for such time as it may think proper,

         but despite any delegation or appointment under the above paragraphs of
         this Clause, the Servicer shall remain liable for the performance of
         the Services in accordance with this Agreement and for the acts or omis
         sions of any officer, employee, attorney, agent, delegate, sub-delegate
         or sub-agent and shall be solely responsible for the fees and expenses
         of such officer, employee, attorney, agent, delegate, sub-delegate or
         sub-agent.

2.6      Servicer's power to appoint advisers

         In accordance with its ordinary course of business, the Servicer may
         appoint and engage and act upon the opinion, advice or information
         obtained from any valuers, solicitors, barristers, accountants,
         surveyors, property managers, real estate agents, contractors,
         qualified advisers and such other persons as may be necessary, usual or
         desirable for the purpose of enabling the Servicer properly to exercise
         and perform its duties and obligations under this Agreement.

2.7      Legal title

         The Servicer agrees that upon being directed to do so by the Trustee
         following a Title Perfection Event for a Relevant Trust, it will
         promptly take all action to perfect the Trustee's legal title to the
         relevant Receivables and Receivable Securities by:

         (a)      giving written notice of the Trustee's interest to any Obligor

         (d)      delivering all Relevant Documents for that Trust to the
                  Trustee. If the Servicer has not done so within 10 Business
                  Days (or such longer period as the Trustee permits) the
                  Trustee may enter any premises where those Relevant Documents
                  are kept, take possession of and remove those Relevant
                  Documents. The Servicer shall assist the Trustee in doing so.

2.8      License to enter Premises

         Westpac irrevocably licenses the Trustee to enter onto the Premises for
         the purpose of taking possession of, and removing, the Relevant
         Documents in accordance with this Agreement.

                  Transaction Document in accordance with its standard
                  safekeeping practises and in the same manner and to the same

         (b)      ensure that each Relevant Document is capable of
                  identification and is kept in a Security Packet which is kept
                  together with other Security Packets relating to the
                  Receivables of that Trust in a security vault, and separate
                  from other documents held by the Servicer for another Trust or
                  otherwise;

         (c)      in relation to each Relevant Trust, open and maintain in safe
                  custody a record of physical movement from the Premises and
                  between each Relevant Trust of any Relevant Document held by

                  Movements);

         (d)      update the Receivables Register and give a copy to the
                  Trustee:

                  (i)      within 3 months of the Closing Date for each Relevant
                           Trust;

                  (ii)     if its holding company has a short term rating from
                           the Designated Rating Agency of not less than A-, not
                           later than the last Business Day of each calendar
                           year during the Term;

                  (iii)    if its holding company does not have such a rating,
                           on the last Business Day of each calendar quarter
                           during the Term; and

                  (iv)     within 30 days of a written request by the Trustee if
                           the Trustee (in its discretion, but acting
                           reasonably) believes that the Servicer or Westpac is
                           breaching its obligations under this Agreement or any
                           other Relevant Document; and

         (e)      at all times during the currency of this Agreement do all
                  acts, matters and things which may reasonably be required of
                  the Servicer by the Trustee for the purposes of, or as
                  contemplated by this Agreement.

3.2      Locate and Access

         (a)      The Servicer shall ensure that at all times it shall be able
                  to locate each Security Packet by way of a periodic Security
                  Packet Audit.

         (b)      Unless the Servicer requires a Relevant Document to perform
                  its duties as Servicer in relation to the related Receivable,
                  or otherwise comply with its obligations under the Transaction
                  Documents, each Relevant Document shall be kept within the
                  Security Vault.

         (c)      Other than the Servicer requiring a Relevant Document under
                  Clause 3.2(b), or for an audit by Westpac's or the Servicer's
                  internal or external auditor, or by the Auditor under Clause
                  3.3 of this Agreement, a Relevant Document may only be removed
                  from the Security Vault with the Trustee's written approval
                  and for the following purposes:

                  (i)      inspection by the Trustee; or

                  (ii)     such other purpose approved in writing by the
                           Trustee.

3.3      Audit

         (a)      The Trust Manager or the Trustee (in default of action by the
                  Trust Manager) shall on each Audit Date request an independent
                  auditor to conduct an audit of the Servicer's custodial role
                  with respect to the Relevant Documents for any Relevant Trust
                  by considering the matters set out in Schedule 2.

         (b)      The terms of the instruction of that auditor must require
                  delivery, within one month of an Audit Date, of a certificate
                  addressed to the Trustee, the Servicer and the Designated
                  Rating Agency stating whether or not the Servicer has complied
                  with the matters set out in Schedule 2.
<PAGE>
                                                                          Page 8
- --------------------------------------------------------------------------------

         (c)      Where a certificate referred to in Clause 3.3(b) (the Audit
                  Certificate) gives an "Adverse" finding (as set out in
                  Schedule 2), the Trustee must direct that auditor to conduct a
                  further audit (the Further Audit) on a similar basis to the
                  audit to which the Audit Certificate related. The Further
                  Audit shall be conducted no later than one month after the
                  date of the Audit Certificate. That auditor shall then issue a
                  new certificate with respect to the Further Audit in the form
                  required by Clause 3.3(b) no later than one month after the
                  date on which the Further Audit commenced.

         (d)      Subject to any bona fide confidentiality restrictions, the
                  Servicer shall give each auditor full access to all relevant
                  information and the Relevant Documents for the purpose of
                  conducting each audit under Clause 3.3.

         (e)      The Trustee shall pay the reasonable fees and expenses of the
                  auditor with respect to any audit under this Clause 3.3.

         (f)      The auditor instructed under this Clause must be instructed to
                  give written reasons supporting any "Adverse" finding.

         (g)      The Servicer shall take all reasonable steps to cure any non
                  compliance identified by an audit.

3.4      Transfer of Custody

         If:

         (a)      a Servicer Transfer Event occurs and is subsisting; or

         (b)      a Custody Transfer Trigger occurs,

         the Servicer must deliver the Relevant Documents to the Trustee, or as
         it directs. If the Servicer has not done so within 10 Business Days (or
         such longer period as the Trustee permits) the Trustee must enter any
         premises where the Relevant Documents are kept, take possession of and
         remove the Relevant Documents. The Servicer shall assist in doing so.
         If the Trustee does not have possession of the Relevant Documents
         within that period it may, to the extent that it has information
         available to it to do so, lodge caveats in relation to and/or take all
         other action it considers necessary to protect its interests in, the
         Receivables and Receivable Securities for which it does not hold the
         Relevant Documents.

4.       UNDERTAKINGS

                  relevant Receivable and the Receivable Security to the extent
                  that the Servicer determines that enforcement procedures
                  should be taken;

                  (ii)     not do or omit to do anything which could be
                           reasonably expected to prejudicially affect or limit
                           its rights or the rights of the Trustee under or in

                  Receivable and the Receivable Security:

                  (i)      without limiting paragraph (f)(ii), unless priority
                           arrangements are entered into with that third party
                           under which the third party acknowledges that the
                           Receivable and Receivable Security ranks ahead in
                           priority to the third party Security Interest on
                           enforcement for an amount not less than the Unpaid
                           Balance of the Receivable plus such other amount as
                           the Servicer determines in accordance with the
                           Procedures Manual or its ordinary course of business;
                           or

                  which has the effect of altering the amount payable in respect

                  or grant other relief to an Obligor, if required to do so by
                  any Law or if ordered to do so by a court, tribunal,
                  authority, ombudsman or other entity whose decisions are
                  binding on the Servicer. If the order is due to the Servicer
                  breaching any applicable Law then the Servicer must indemnify
                  the Trustee for any loss the Trustee may suffer by reason of
                  the order. The amount of the loss is to be determined by

                  following any amendment, consolidation or other action, and 
                  in the case of any registration of any Mortgage that 
                  registration must result in the Mortgage having the ranking 
                  referred to in the relevant eligibility criteria in the 
                  Series Notice. In relation to any Mortgage that is not 
                  registered at the relevant Closing Date, the Servicer shall 
                  ensure that it is lodged for registration not later than 
                  120 days after that Closing Date;

         (j)      (setting the Interest Rate)

                  (i)      the Servicer shall set the interest rate on the
                           Receivables in accordance with the requirements of
                           the Series Notice; and

                  (ii)     subject to the relevant Series Notice, if the Trustee
                           has perfected its title to the Receivables or
                           Receivable Securities and the Trustee is entitled to
                           vary the interest rate in accordance with the terms
                           of the Receivables, the Servicer shall, in accordance
                           with the terms of the Receivables, set and maintain
                           the interest rate on the relevant Receivables at or
                           above the relevant Threshold Rate as advised by the
                           Trust Manager in accordance with the Master Trust
                           Deed and the Series Terms and promptly notify the
                           relevant Obligors;

         (k)      (notification) notify:

                           it reasonably believes is likely to have an Adverse

                           and

                           Manager reasonably requires regarding any proposed
                           modification to any Receivable or Receivable
                           Security.

         (l)      (provide information and access on request) provide

                  Manager, with respect to all matters relating to each Relevant

                  the Trust Manager believes reasonably necessary for it to
                  perform its obligations under the relevant Transaction
                  Documents, and upon reasonable notice and at reasonable times
                  permit the Trustee to enter the Premises and inspect the Data

         (p)      (availability of Data Base) make the Data Base that relates to
                  the Services available for inspection by the Trustee at any
                  reasonable time;

                  immediately of each request by an Obligor to borrow further
                  moneys under or in relation to a Receivable or Receivable
                  Security which is a "top-up" and which the Servicer has

                  prejudicially affect or limit the rights of the Trustee under
                  or in respect of a Mortgage Insurance Policy to the extent
                  those rights relate to a Receivable and the Receivable
                  Security;

         (f)      (no Security Interests) not consent to the creation or
                  existence of any Security Interest in favour of a third party
                  in relation to any Mortgaged Property in connection with a
                  Receivable and the Receivable Security:

                  (i)      without limiting paragraph (f)(ii), unless priority
                           arrangements are entered in to with that third party
                           under which the third party acknowledges that the
                           Receivable and Receivable Security ranks ahead in
                           priority to the third party Security Interest on
                           enforcement for an amount not less than the Unpaid
                           Balance of the Receivable plus such other amount as
                           the Servicer determines in accordance with the
                           Procedures Manual or its ordinary course of business;
                           or

                  (ii)     which would rank before or pari passu with the
                           relevant Receivable and Receivable Security;

         (g)      (release of debt or vary terms) not, except as required by
                  Law, release an Obligor from any amount owing in respect of a
                  Receivable or otherwise vary or discharge any Receivable or
                  Receivable Security or enter into any agreement or arrangement
                  which has the effect of altering the amount payable in respect
                  of a Receivable or Receivable Security where it would have an
                  Adverse Effect;

         (h)      (binding provisions and orders of a competent authority)
                  release any Receivable or Receivable Security, reduce the
                  amount outstanding under or vary the terms of any Receivable
                  or grant other relief to an Obligor, if required to do so by
                  any Law or if ordered to do so by a court, tribunal,
                  authority, ombudsman or other entity whose decisions are
                  binding on Westpac. If the order is due to Westpac breaching
                  any applicable Law then Westpac must indemnify the Trustee for
                  any loss the Trustee may suffer by reason of the order. The
                  amount of the loss is to be determined by agreement with the

                  and

         (j)      (additional amounts) notify the Servicer immediately of each
                  request by an Obligor to borrow further moneys under or in
                  relation to a Receivable or Receivable Security.

4.3      Westpac's power to delegate

         (a)      For so long as Westpac is the legal owner of any Receivables,
                  and Westpac is required by Law (including, without limitation,
                  the Consumer Credit Code) to do, or refrain from doing,
                  certain things in relation to those Receivables or the
                  Receivable Securities:

                  (i)      Westpac appoints the Servicer to do those things on
                           its behalf, except as specified in the Procedures
                           Manual;

                  (ii)     Westpac directs the Servicer to perform the Services
                           in a manner that is consistent with any obligation of
                           Westpac under any Law;

                  (iii)    Westpac authorises the Servicer to conduct
                           correspondence with Obligors and other persons as if
                           it had been appointed to perform the Services by
                           Westpac as legal owner of those Receivables and
                           Receivable Securities, 
<PAGE>

                                                                         Page 13
- --------------------------------------------------------------------------------

                           but this authorisation is subject to any restriction
                           imposed on the Servicer in any power of attorney or
                           the Procedures Manual; and

                  (iv)     the Servicer accepts that appointment and direction
                           and agrees to perform the Services in accordance with
                           this Agreement.

         (b)      Despite any delegation under this Clause, Westpac shall remain
                  liable in relation to any obligation it delegates to the
                  Servicer, and for the acts, omissions, fees and expenses of
                  the Servicer as its delegate.

4.4      Adverse Effect

         (a)      In performing the Services the Servicer shall have regard to
                  whether what it does, or does not do, will have any Adverse
                  Effect.

         (b)      The Servicer may ask the Trustee or the Trust Manager if any
                  action or inaction on its part is reasonably likely to, or
                  will, have an Adverse Effect.

         (c)      The Servicer may rely upon any statement by the Trustee or the
                  Trust Manager that any action or inaction by the Servicer is
                  reasonably likely to, or will, have an Adverse Effect.

         (d)      Subject to paragraph (a), the Servicer shall not be liable for
                  a breach of this Agreement, or be liable under ^ any
                  indemnity, in relation to any action or inaction on its part,
                  where it has been notified by the Trustee or the Trust Manager
                  that the action or inaction is not reasonably likely to, or
                  will not have an Adverse Effect.

                           comply with any Law; or

                  (ii)     the Servicer is not otherwise complying with

                           matter or duty.

         of any material amendment to the relevant Procedures Manual.

6.       COLLECTION AND REMITTANCE OF MONEYS

6.1      Collection of moneys

         (a)      Westpac shall on behalf of the Trustee collect and receive the
                  Collections in respect of Receivables in relation to which
                  Westpac is the legal owner.

         (b)      In collecting and receiving the Collections for Receivables in
                  relation to which it is the legal owner, Westpac shall:

                  (i)      act in accordance with the standards and practices
                           applied by Westpac to other assets which it owns in
                           the ordinary course of its business and in accordance
                           with the Procedures Manual; and

                  (ii)     exercise the degree of diligence and care expected of
                           an appropriately qualified lender in relation to the
                           relevant financial products.

         (c)      Westpac may delegate to the Servicer the collection and
                  receipt of the Collections referred to in paragraph (a).
                  Westpac may revoke that delegation. Westpac shall remain
                  liable under paragraph (a) despite any delegation under this
                  paragraph (c). If Westpac delegates to the Servicer the
                  collection and receipt of any Collections, the Servicer must
                  not deposit any Collections in its own account, and shall
                  deposit them in the relevant Collections Account not later
                  than the time that Westpac would have been required to deposit
                  them under this Agreement.

         (d)      Following the perfection of title to any Receivable and
                  Receivable Rights, the Servicer shall assist the Trustee in
                  relation to the collection and receipt of Collections in
                  respect of those Receivables and Receivable Rights.

6.2      Remittances

         (a)      If Westpac has a short term rating of A-1+ from the Designated
                  Rating Agency, or otherwise satisfies the requirements of the
                  Designated Rating Agency so that any rating given by the
                  Designated Rating Agency in respect of the Notes will not be
                  adversely affected, Westpac must pay the Collections it
                  receives during a Collection Period on the Remittance Date for
                  that Collection Period into the relevant Collections Account.

         (b)      Subject to the terms of the relevant Series Notice, on that
                  Remittance Date, Westpac must pay into the relevant Collection
                  Account an amount equal to the aggregate of:

                  (i)      the Collections received during the Collection Period
                           relating to that Remittance Date; and

                  (ii)     an amount equal to the interest that would have been
                           earned on such Collections received by it if they had
                           been deposited into the relevant Collection Account
                           five Business Days following receipt by the Servicer,

                  less an amount equal to any Taxes payable in relation to those
                  Collections and any other amount Westpac may retain in
                  accordance with any relevant Series Notice.

         (c)      If Westpac does not have a short term rating of A1+ from the
                  Designated Rating Agency, or otherwise does not satisfy the
                  requirements of the Designated Rating Agency so that the
                  rating given by the Designated Rating Agency in respect of the
                  Notes will be adversely affected, then Westpac shall pay all
                  Collections in its possession or control into the relevant
                  Collection Account no later than five Business Days following
                  receipt.

                  is, or is returned, dishonoured, Westpac shall be entitled to
                  a return of the amount remitted to the Trustee for which
                  Westpac did not receive funds from the Obligor. Westpac may

                  Trust Manager or the act or omission of the Trustee or the
                  Trust Manager except to the extent that it is caused by the

                  contract; or

         (b)      for any loss, cost, liability or expense caused by its failure

                  Manager except to the extent that the loss is caused by the
                  Servicer's own fraud, negligence or breach of duty or
                  contract.

                  (i)      is a continuing obligation;

                  (ii)     is a separate and independent obligation; and

                  (iii)    survives termination or discharge of this Agreement.

11.      WESTPAC AND THE SERVICER MAY ACT AS BANKER

         Each of Westpac and the Servicer may (without having to account to the
         Trustee) engage in any kind of banking, finance, trust or other
         business permitted under any law with any Obligor as if, in the case of
         Westpac, it did not have obligations under this Agrement, and, in the
         case of the Servicer, it were not the Servicer. Neither Westpac nor the
         Servicer shall not be required to account to the Trustee for any moneys
         received by it on any account that is unrelated to Receivables and
         Receivable Securities or the Services.

                                   SCHEDULE 2

                                      AUDIT

1.       Each audit referred to in Clause 3.3 shall involve a review of the
         following:

         (a)      the custodial procedures adopted by the Servicer;

         (b)      that the Relevant Documents are capable of identification,
                  segregated by reference to the relevant Portfolio of
                  Receivables and from other mortgage title documents held by
                  the Servicer;

         (c)      that controls exist such that the Relevant Documents may not
                  be removed or tampered with except with appropriate
                  authorisation; and

         (d)      that an appropriate tracking system is in place such that the
                  location of the Relevant Documents can be detected at any
                  time.

2.       The Auditor will review a sample of the Security Packets and confirm
         that those Security Packets contain the Relevant Documents which the
         Series Terms indicate that they should (including, as a minimum, the
         Receivable Security documents, and any Certificate of Title if issued).

3.       The Auditor's certificate referred to in Clause 3.3 will set out
         whether any errors detected by the Auditor in the relevant audit were
         the result of isolated non-compliance with the control system
         established by the Servicer under this Agreement or result from a
         weakness in that control system.

4.       The Auditor's certificate referred to in Clause 3.3 will grade the
         custodial performance of the Servicer under this Agreement based on the
         following grades.

         (A)      Good -            All control procedures and accuracy of
                                    information in respect of Relevant Documents
                                    completed without exception, other than
                                    immaterial and occasional variances.

         (B)      Satisfactory -    Minor exceptions to compliance with control
                                    procedures and accuracy of information in
                                    respect of Relevant Documents

         (C)      Improvement
                  required -        Base internal controls are in place but a
                                    number of issues were identified that need
                                    to be resolved for controls to be considered
                                    adequate; and testing of the relevant
                                    information in respect of Relevant Documents
                                    identified a number of minor exceptions to
                                    compliance which are the result of
                                    non-compliance with the control system

         (D)      Adverse -         Major deficiencies in internal controls and
                                    the relevant information in respect of the
                                    Relevant Documents were identified.

                                    Clause 33 of the Master Trust Deed applies
                                    to the obligations and liabilities of the

                       (b)          Liability of Trustee limited to its right of
                                    indemnity

                                    (i)     This agreement applies to the

                                            which it can be satisfied out of
                                            property of the Trust out of which

                                            may not sue the Trustee in any
                                            capacity other than as trustee of

                                            because under a Transaction Document
                                            or by operation of law there is a
                                            reduction in the extent of the
                                            Trustee's indemnification out of the

3.1      Liquidity Draw

         (a)      Subject to this agreement, if on any Determination Date the
                  Trust Manager determines that there is a Liquidity Shortfall
                  in relation to the Collection Period ending immediately prior
                  to the Determination Date, the Trust Manager must direct the

                  and the Series Notice) request a Liquidity Draw by giving to
                  the Liquidity Provider a Drawdown Notice.

         (b)      A Drawdown Notice must be:

                  (i)      in writing;

                  (ii)     in or substantially in the form of Annexure A;

                  of:

                  (i)      the relevant Liquidity Shortfall; and

                  (ii)     subject to paragraph (d), the Available Liquidity

         (d)      If:

                  (i)      the aggregate of all payments required to be made
                           under clauses 6.10(a)(i) to (iii) inclusive of the
                           Series Notice on the relevant Payment Date; plus

                  (ii)     the outstanding Liquidity Draws due to be repaid on
                           that date; minus

                  (iii)    the Available Income for the relevant Collection
                           Period;

                  is equal to or less than the Liquidity Limit, the calculation
                  of Available Liquidity Amount in paragraph (c)(ii) shall
                  assume the repayment of all Liquidity Draws due to be repaid
                  on or before the relevant Drawdown Date.

         (e)      The Trustee irrevocably authorises the Liquidity Provider to
                  apply against a Liquidity Draw provided on any Drawdown Date
                  all amounts which are assumed to have been applied in repaying
                  previous Liquidity Draws as contemplated by paragraph (d).

         (f)      In the case of a Liquidity Draw provided:

                  (i)      in accordance with paragraph (c)(i); or

                  (ii)     following an application of paragraph (d),

                  the Liquidity Provider will only be required to advance to the
                  Trustee the difference (if any) between the Liquidity Draw and
                  the Available Liquidity Amount immediately prior to the
                  relevant Drawdown Date.

3.2      Making of Liquidity Draws

         Subject to the terms of this agreement, a Liquidity Draw requested in a
         Drawdown Notice shall be made available:

         (a)      other than during a Liquidity Collateralisation Period, by the
                  Liquidity Provider crediting the proceeds of that Liquidity
                  Draw to the Collection Account by no later than 11.00 am
                  (Sydney time) on the relevant Payment Date;

         (b)      during a Liquidity Collateralisation Period when the
                  Collateral Account is maintained with the Liquidity Provider,
                  by the Trust Manager directing the Trustee to transfer the
                  amount of that Liquidity Draw from the Collateral Account to
                  the Collection Account; and

         (c)      during a Liquidity Collateralisation period when the
                  Collateral Account is not maintained with the Liquidity
                  Provider, by the Trust Manager directing the Trustee to
                  arrange to transfer the amount of that Liquidity Draw from the
                  Collateral Account to the Collection Account, in satisfaction
                  of the Liquidity Provider's obligation to make that Liquidity
                  Draw available, provided that none of the Liquidity Provider,
                  the Trust Manager nor the Trustee shall have any obligation if
                  for any reason the Bank maintaining the Collateral Account
                  does not comply with a request or direction to make a transfer
                  requested from the Collateral Account.

3.3      Collateral Account

         If at any time the Liquidity Provider's short term credit rating is
         less than A-1+ from S&P or P-1 from Moody's, or S&P or Moody's cease to
         provide a short term credit rating for the

                                                                         Page 6
- --------------------------------------------------------------------------------


         Liquidity Provider (other than because S&P or Moody's, as the case may
         be, ceases to provide such ratings generally):

         (a)      the Trustee must as soon as practicable establish and maintain
                  in the name of the Trustee an account with a Bank having a
                  short term rating of A-1 from S&P and P-1 from Moody's or
                  which otherwise satisfies the requirements of those Designated
                  Rating Agencies; and

         (b)      the Liquidity Provider must within 5 Business Days or such
                  longer period as each Designated Rating Agency may agree,
                  deposit into that account an amount equal to the Available
                  Liquidity Amount at that time.

3.4      Collateral Account with Liquidity Provider

         If and for so long as the Liquidity Provider has a short term credit
         rating from S&P of not lower than A-1 and from Moody's of not lower
         than P-1, the Collateral Account shall be an account with the Liquidity
         Provider.

3.5      New Account

         If at any time:

         (a)      the short term credit rating of the Bank holding the
                  Collateral Account (the Existing Collateral Account) from S&P
                  is lower than A-1 or from Moody's is lower than P-1; or

         (b)      deposits credited to the Existing Collateral Account cease to
                  be Authorised Investments because of paragraph (g)(B) of the
                  definition of Authorised Investments in clause 1.1 of the
                  Master Trust Deed,

         the Trust Manager must direct the Trustee to, and the Trustee must,
         subject to clause 3.6, within 5 Business Days after such direction (or
         such longer period as each Designated Rating Agency may agree):

         (a)      establish a new account with a Bank which has a short term
                  credit rating from S&P of not lower than A-1+ and from Moody's
                  of not lower than P-1 (the New Collateral Account) in the name
                  of the Trustee; and

         (b)      transfer so much of the balance of the Existing Collateral
                  Account to the New Collateral Account as is not an Authorised
                  Investment by application of paragraph (b).

3.6      Conditions to transfer of account balance

           The Trustee shall only be obliged to transfer the balance of the
           Existing Collateral Account to the New Collateral Account in
           accordance with clause 3.5(d) if both the Trust Manager and the
           Liquidity Provider are satisfied that the terms upon which the New
           Collateral Account is established and maintained are such that:

         (a)      the Bank with which the New Collateral Account is maintained
                  will have no right of set-off, combination of accounts, lien,
                  flawed deposit or other Security Interest over the New
                  Collateral Account; and

         (b)      the terms of the New Collateral Account may not be varied in
                  any way without the prior written consent of the Liquidity
                  Provider.

         The Trust Manager and the Liquidity Provider must provide the Trustee
         with written notice of their satisfaction with these matters as soon as
         practicable.

3.7      Withdrawal from accounts

         (a)      The Trustee may only make withdrawals from a Collateral
                  Account if directed to do so by the Trust Manager, and then
                  only for the following purposes:

                  (i)      to make or fund a Liquidity Draw in accordance with
                           this agreement;

                  (iv)     to withdraw any amount which has been incorrectly
                           deposited into the Collateral Account;

                  (v)      to pay financial institutions duty, bank accounts
                           debit tax or equivalent payable in respect of the
                           Collateral Account;

                  (vi)     at the direction of the Trust Manager, invest in
                           Authorised Investments which mature no later than the
                           end of the Funding Period in which the Authorised
                           Investments were acquired provided that all amounts
                           received by the Trustee on that maturity must be
                           credited to the Collateral Account;

                  (vii)    to refund to the Liquidity Facility Provider the
                           amount of any of the Liquidity Limit which is
                           cancelled under clause 7.1.

         (b)      The Trust Manager must only direct the Trustee to make
                  withdrawals from the Collateral Account for the above
                  purposes.

         (c)      For so long as the Collateral Account is maintained with the
                  Liquidity Provider, the obligations of the Liquidity Provider
                  with respect to payment to the Trustee of the debt constituted
                  by any credit balance on the Collateral Account shall be
                  conditional upon and subject to the terms of this clause 3.

3.8      Liquidity Provider upgrade

         (a)      If, at any time when the Collateral Account is not maintained
                  with the Liquidity Provider, a short term credit rating of the
                  Liquidity Provider is upgraded so that it has a rating from
                  S&P of not lower than A-1 and from Moody's of not lower than
                  P-1, the Trust Manager must direct the Trustee to, and the

                  arrange for the Cash Advance Deposit to be transferred to an
                  account with the Liquidity Provider (which account will then
                  become the Collateral Account).

         (b)      If at any time during a Liquidity Collateralisation Period a
                  short term credit rating of the Liquidity Provider is upgraded
                  so that it has a rating from S&P of A-1+ and from Moody's of
                  P-1, the Trust Manager must direct the Trustee to, and the
                  Trustee must within 5 Business Days of being so directed,
                  repay to the Liquidity Provider the balance of the Collateral

10.      PAYMENTS

10.1     Manner

         Subject to clause 8.3, the Trustee shall make all payments under this
         agreement:

         (a)      by cheque, electronic funds transfer or other agreed method to
                  the Liquidity Provider at its address for service of notices
                  or by transfer of immediately available funds to the account
                  specified by the Liquidity Provider and, in either case, by
                  4.00 pm (Sydney time) on the due date; and

         (b)      without set-off, counterclaim or other deduction, except any
                  compulsory deduction for Taxation; and

         (c)      in accordance with the directions of the Trust Manager, the
                  Master Trust Deed and the Series Notice.

         Subject to any express provision of this agreement, the Liquidity
         Provider may appropriate amounts it receives as between principal,
         interest and other amounts then payable as it sees fit. This will
         override any appropriation made by the Trustee.

11.      CHANGES IN LAW

11.1     Additional payments

         Whenever the Liquidity Provider determines that:

         (a)      the effective cost to the Liquidity Provider of making,
                  funding or maintaining any Liquidity Draw or the Liquidity
                  Limit is increased in any way;

         (b)      any amount paid or payable to the Liquidity Provider or
                  received or receivable by the Liquidity Provider, or the
                  effective return to the Liquidity Provider, under or in
                  respect of this agreement is reduced in any way;

         (c)      the return of the Liquidity Provider on the capital which is
                  or becomes directly or indirectly allocated by the Liquidity
                  Provider to any Liquidity Draw or the Liquidity Limit is
                  reduced in any way; or

         (d)      to the extent any relevant law, official directive or request
                  relates to or affects the Liquidity Limit, any Liquidity Draw
                  or this agreement, the overall return on capital of the
                  Liquidity Provider or any of its holding companies is reduced
                  in any way,

         as a result of any change in, any making of or any change in the
         interpretation or application by any Government Agency of, any law,
         official directive or request, then:

         (c)      (when it has calculated the effect of the above and the amount
                  to be charged to the Trustee under this clause) the Liquidity
                  Provider shall promptly notify the Trust Manager and the
                  Trustee; and


<PAGE>

                                                                         Page 11
- --------------------------------------------------------------------------------

           (d)       on the following Payment Date the Trustee shall, subject
                     to clause 6 of the Series Notice, pay for the account of
                     the Liquidity Provider the amount certified by an
                     Authorised Signatory of the Liquidity Provider to be
                     necessary to compensate the Liquidity Provider for the
                     increased cost or the reduction (from the date of the
                     notice).

           Without limiting the above in any way, this clause applies:

           (g)       to any law, official directive or request with respect to
                     Taxation (other than any Tax on the net income of any
                     person) or reserve, liquidity, capital adequacy, special
                     deposit or similar requirements;

           (h)       to official directives or requests which do not have the
                     force of law where it is the practice of responsible
                     bankers or financial institutions in the country
                     concerned to comply with them; and

           (i)       where the increased cost or the reduction arises because
                     the Liquidity Provider is restricted in its capacity to
                     enter other transactions, is required to make a payment,
                     or forgoes or earns reduced interest or other return on
                     any capital or on any sum calculated by reference in any
                     way to the amount of any Liquidity Draw, the Liquidity
                     Limit or to any other amount paid or payable or received
                     or receivable under this agreement or allocates capital
                     to any such sum.

11.2   Minimisation

           (a)       (No defence) If the Liquidity Provider has acted in good
                     faith it will not be a defence that any cost, reduction
                     or payment referred to in this clause could have been
                     avoided.

           (b)       (Minimisation) The Liquidity Provider shall use
                     reasonable endeavours to minimise any cost, reduction or
                     payment referred to in this clause.

11.3       Survival

           This clause survives the repayment of any relevant Liquidity Draw and
the termination of this agreement.

                  power or remedy under this agreement operates as a waiver. Nor
                  does any single or partial exercise of any right, power or
                  remedy preclude any other or further exercise of that or any

19.      SEVERABILITY OF PROVISIONS

         Any provision of this agreement which is prohibited or unenforceable in
         any jurisdiction is ineffective as to that jurisdiction to the extent

         remaining provisions of this agreement nor affect the validity or
         enforceability of that provision in any other jurisdiction.

         directly or indirectly:

         (a)      lessens, varies or affects in favour of the Trustee any
                  obligation under a Trust Document; or

         (b)      delays, prevents or prejudicially affects the exercise by the

                  this agreement, is excluded from this agreement.

30.      LIMITED RECOURSE

30.1     General

         Clause 33 of the Master Trust Deed applies to the obligations and
         liabilities of the Trustee and the Trust Manager under this agreement.

30.2     Liability of Trustee limited to its right to indemnity

         (a)      This agreement applies to the Trustee only in its capacity as
                  trustee of the Trust and in no other capacity. A liability
                  arising under or in connection with this agreement or the
                  Trust can be enforced against the Trustee only to the extent
                  to which it can be satisfied out of property of the Trust out
                  of which the Trustee is actually indemnified for the
                  liability. This limitation of the Trustee's liability applies
                  despite any other provision of this agreement and extends to
                  all liabilities and obligations of the Trustee in any way
                  connected with any representation, warranty, conduct,
                  omission, agreement or transaction related to this agreement
                  or the Trust.

         (b)      The parties other than the Trustee may not sue the Trustee in
                  any capacity other than as trustee of the Trust or seek the
                  appointment of a receiver (except under the Security Trust
                  Deed), or a liquidator, an administrator or any similar person
                  to the Trustee or prove in any liquidation, administration or
                  arrangements of or affecting the Trustee.

         (c)      The provisions of this clause 30 shall not apply to any
                  obligation or liability of the Trustee to the extent that it
                  is not satisfied because under a Transaction Document or by
                  operation of law there is a reduction in the extent of the
                  Trustee's indemnification out of the Assets of the Trust as a
                  result of the Trustee's fraud, negligence or breach of trust.

         (d)      It is acknowledged that the Trust Manager, the Servicer, the
                  Note Trustee, the Principal Paying Agent, the other Paying
                  Agents and the Agent Bank (each a Relevant Party) are
                  responsible under this agreement and the other Transaction
                  Documents for performing a variety of obligations relating to
                  the Trust. No act or omission of the Trustee (including any
                  related failure to satisfy its obligations under this
                  agreement) will be considered fraud, negligence or breach of
                  trust of the Trustee for the purpose of sub-paragraph (c) to
                  the extent to which the act or omission was caused or
                  contributed to by any failure by any Relevant Party or any
                  other person who provides services in respect of the Trust
                  (other than a person who has been delegated or appointed by
                  the Trustee and for whom the Trustee is responsible under this
                  agreement or the relevant Transaction Documents, but excluding
                  any Relevant Party) to fulfil its obligations relating to the
                  Trust or by any other act or omission of a Relevant Party or
                  any other person who provides services in respect of the Trust
                  (other than a person who has been delegated or appointed by
                  the Trustee and for whom the Trustee is responsible under this
                  agreement or the relevant Transaction Documents, but excluding
                  any Relevant Party).

         (e)      No attorney, agent, receiver or receiver and manager appointed
                  in accordance with this agreement or any other Transaction
                  Documents (including a Relevant Party) has authority to act on
                  behalf of the Trustee in a way which exposes the Trustee to
                  any

                  personal liability and no act or omission of any such
                  person will be considered fraud, negligence or breach of trust
                  of the Trustee for the purpose of sub-paragraph (c), if the
                  Trustee has exercised reasonable care in the selection and
                  supervision of such a person.

30.3     Unrestricted remedies

         Nothing in clause 30.2 limits the Liquidity Provider in:

         (a)      obtaining an injunction or other order to restrain any breach
                  of this agreement by any party;

         (b)      obtaining declaratory relief; or

         (c)      in relation to its rights under the Security Trust Deed.

                  damages by the Trustee;

         (b)      (statutory demand) issue any demand under s459E(1) of the
                  Corporations Law (or any analogous provision under any other
                  law) against the Trustee;

         (c)      (winding up) apply for the winding up or dissolution of the
                  Trustee;

         (d)      (execution) levy or enforce any distress or other execution
                  to, on, or against any assets of the Trustee;

         (e)      (court appointed receiver) apply for the appointment by a
                  court of a receiver to any of the assets of the Trustee;

         (g)      (administrator) appoint, or agree to the appointment, of any
                  administrator to the Trustee,

         or take proceedings for any of the above and the Liquidity Provider
         waives its rights to make those applications and take those
         proceedings.

31.      LIQUIDITY PROVIDER'S OBLIGATIONS

         The Trustee shall have no recourse to the Liquidity Provider in
         relation to this agreement beyond its terms, and the Liquidity
         Provider's obligations under this agreement are separate from, and
         independent to, any obligations the Liquidity Provider may have to the
         Trustee for any other reason (including under any other Trust

         (a)      a reference to an asset includes any real or personal, present
                  or future, tangible or intangible property or asset and any
                  right, interest, revenue or benefit in, under or derived from
                  the property or asset;

         (b)      an Event of Default subsists until it has been waived in
                  writing by the Redraw Facility Provider; and

         (c)      a reference to an amount for which a person is contingently
                  liable includes an amount which that person may become
                  actually or contingently liable to pay if a contingency
                  occurs, whether or not that liability will actually arise.

1.4      Determination, statement and certificate sufficient evidence

         Except where otherwise provided in this agreement any determination,
         statement or certificate by the Redraw Facility Provider or an
         Authorised Signatory of the Redraw Facility Provider provided for in
         this agreement is sufficient evidence unless proven wrong.

1.5      Transaction Document

         This agreement is a Transaction Document for the purposes of the Master
         Trust Deed.

1.6      Limited to Trust

         The rights and obligations of the parties under this agreement relate
         only to the Trust, and do not relate to any other Trust (as defined in
         the Master Trust Deed). Without limitation, the Redraw Facility
         Provider has no obligation under this agreement to provide financial

                  Notice), direct the Trustee to request a Redraw Advance by

                  Redraw Advance if as a result the aggregate of Principal

9.       CHANGES IN LAW

9.1      Additional payments

         Whenever the Redraw Facility Provider determines that:

         (a)      the effective cost to the Redraw Facility Provider of making,
                  funding or maintaining any Redraw Advance or the Redraw Limit
                  is increased in any way;

         (b)      any amount paid or payable to the Redraw Facility Provider or
                  received or receivable by the Redraw Facility Provider, or the
                  effective return to the Redraw Facility Provider, under or in
                  respect of this agreement is reduced in any way;

         (c)      the return of the Redraw Facility Provider on the capital
                  which is or becomes directly or indirectly allocated by the
                  Redraw Facility Provider to any Redraw Advance or the Redraw
                  Limit is reduced in any way; or

         (d)      to the extent any relevant law, official directive or request
                  relates to or affects the Redraw Limit, any Redraw Advance or
                  this agreement, the overall return on capital of the Redraw
                  Facility Provider or any of its holding companies is reduced
                  in any way,

         as a result of any change in, any making of or any change in the
         interpretation or application by any Government Agency of, any law,
         official directive or request, then:

<PAGE>

                                                                          Page 8
- --------------------------------------------------------------------------------

         (e)      (when it has calculated the effect of the above and the amount
                  to be charged to the Trustee under this clause) the Redraw
                  Facility Provider shall promptly notify the Trust Manager and
                  the Trustee; and

         (f)      on the following Payment Date from time to time the Trustee
                  shall, subject to clause 6 of the Series Notice, pay for the
                  account of the Redraw Facility Provider the amount certified
                  by an Authorised Signatory of the Redraw Facility Provider to
                  be necessary to compensate the Redraw Facility Provider for
                  the increased cost or the reduction (from the date of the
                  notice).

         Without limiting the above in any way, this clause applies:

         (g)      to any law, official directive or request with respect to
                  Taxation (other than any Tax on the net income of any person)
                  or reserve, liquidity, capital adequacy, special deposit or
                  similar requirements;

         (h)      to official directives or requests which do not have the
                  force of law where it is the practice of responsible bankers 
                  or financial institutions in the country concerned to comply 
                  with them; and

         (i)      where the increased cost or the reduction arises because the
                  Redraw Facility Provider is restricted in its capacity to
                  enter other transactions, is required to make a payment, or
                  forgoes or earns reduced interest or other return on any
                  capital or on any sum calculated by reference in any way to
                  the amount of any Redraw Advance, the Redraw Limit or to any
                  other amount paid or payable or received or receivable under
                  this agreement or allocates capital to any such sum.

9.2      Minimisation

         (a)      (No defence) If the Redraw Facility Provider has acted in good
                  faith it will not be a defence that any cost, reduction or
                  payment referred to in this clause could have been avoided.

         (b)      (Minimisation) The Redraw Facility Provider shall use
                  reasonable endeavours to minimise any cost, reduction or
                  payment referred to in this clause.

9.3      Survival

         This clause survives the repayment of any relevant Redraw Advance and
         the termination of this agreement.

         (b)      The parties other than the Trustee may not sue the Trustee in
                  any capacity other than as trustee of the Trust or seek the
                  appointment of a receiver (except under the Security Trust
                  Deed), or a liquidator, an administrator or any similar person
                  to the Trustee or prove in any liquidation, administration or
                  arrangements of or affecting the Trustee.

         (c)      The provisions of this clause 3 shall not apply to any
                  obligation or liability of the Trustee to the extent that it
                  is not satisfied because under a Transaction Document or by
                  operation of law there is a reduction in the extent of the
                  Trustee's indemnification out of the Assets of the Trust as a
                  result of the Trustee's fraud, negligence or breach of trust.

         (d)      It is acknowledged that the Trust Manager, the Servicer, the
                  Note Trustee, the Principal Paying Agent, the other Paying
                  Agents and the Agent Bank (each a Relevant Party) are
                  responsible under this agreement and the other Transaction
                  Documents for performing a variety of obligations relating to
                  the Trust. No act or omission of the Trustee (including any
                  related failure to satisfy its obligations under this
                  agreement) will be considered fraud, negligence or breach of
                  trust of the Trustee for the purpose of sub-paragraph (c) to
                  the extent to which the act or omission was caused or
                  contributed to by any failure by any Relevant Party or any
                  other person who provides services in respect of the Trust
                  (other than a person who has been delegated or appointed by
                  the Trustee and for whom the Trustee is responsible under this
                  agreement or the relevant Transaction Documents, but excluding
                  any Relevant Party) to fulfil its obligations relating to the
                  Trust or by any other act or omission of a Relevant Party or
                  any other person who provides services in respect of the Trust
                  (other than a person who has been delegated or appointed by
                  the Trustee and for whom the Trustee is responsible under this
                  agreement or the relevant Transaction Documents, but excluding
                  any Relevant Party).

         (e)      No attorney, agent, receiver or receiver and manager appointed
                  in accordance with this agreement or any other Transaction
                  Documents (including a Relevant Party) has authority to act on
                  behalf of the Trustee in a way which exposes the Trustee to
                  any personal liability and no act or omission of any such
                  person will be considered fraud, negligence or breach of trust
                  of the Trustee for the purpose of sub-paragraph (c), if the
                  Trustee has exercised reasonable care in the selection and
                  supervision of such a person.

         (c)      in relation to its rights under the Security Trust Deed.

                  law) against the Trustee;

                  Trustee;

                  administrator to the Trustee,

         or take proceedings for any of the above and the Redraw Facility
         Provider waives its rights to make those applications and take those
         proceedings.

28.      REDRAW FACILITY PROVIDER'S OBLIGATIONS

         The Trustee shall have no recourse to the Redraw Facility Provider in
         relation to this agreement beyond its terms, and the Redraw Facility
         Provider's obligations under this agreement are separate from, and
         independent to, any obligations the Redraw Facility Provider may have
         to the Trustee for any other reason (including under any other Trust
         Document).

29.      SUCCESSOR TRUSTEE

         The Redraw Facility Provider shall do all things reasonably necessary
