Ladies and Gentlemen:

Westpac Securities Administration Limited (ABN 77 000 049 472), a limited liability public company under the Corporations Act 2001 of the Commonwealth of Australia (“WSAL”) in its capacity as trustee of the Series 2005-1G WST Trust (the “Issuer Trustee”) proposes to sell to the several Underwriters listed in Schedule I hereto (the “Underwriters”), for whom you are acting as representative (the “Representative”), U.S.$1,100,000,000 principal amount of Class A1 Mortgage Backed Floating Rate Notes (the “Notes” or the “Class A1 Notes”) issued by the Series 2005-1G WST Trust (the “Trust”). Each Note will be secured by the assets of the Trust. The assets of the Trust include, among other things, a pool of variable rate residential housing loans (the “Housing Loans”) originated or acquired by Westpac Banking Corporation (ABN 33 007 457 141) (“Westpac”) including all monies at any time paid or payable thereon or in respect thereof from, on and after January 14, 2005 (the “Cut-Off Date”) with respect to payments of principal and after February 8, 2005 (the “Closing Date”) with respect to payments of interest, rights under certain insurance policies with respect to the Housing Loans, the collection account relating to the Trust and the rights of the Issuer Trustee under the Master Trust Deed, the Series Notice, the Servicing Agreement, the Notes, the Security Trust Deed, the Note Trust Deed, the Swap Agreements and the Agency Agreement (the “Basic Documents”). The Trust will be created pursuant to the Master Trust Deed, dated February 14, 1997 (the “Master Trust Deed”) between the Issuer Trustee and The Mortgage Company Pty Limited (ABN 86 070 968 302) and a series notice, to be dated February 4, 2005 (the “Series Notice”), between the Issuer Trustee and Westpac Securitisation Management Pty Limited (ABN 73 081 709 211) (the “Trust Manager”), which sets forth specific provisions regarding the Trust and details the provisions of the Notes. The Note Trust Deed, to be dated on or about February 4, 2005 (the “Note Trust

Deed”) by and among the Issuer Trustee, the Trust Manager and Deutsche Bank Trust Company Americas (the “Note Trustee”) will provide for the issuance and registration of the Notes in accordance with the terms and conditions attached thereto. Westpac will act as servicer (the “Servicer”) of the Housing Loans. The Trust Manager and Westpac (except in its capacity as Servicer) are each a “Westpac Party” and collectively are referred to herein as the “Westpac Parties.” The Notes are described in the Prospectus (as defined below) which the Trust Manager has furnished to the Underwriters.

To the extent not defined herein, capitalized terms used herein have the meanings assigned to such terms in the Series Notice and the Master Trust Deed.

In this Agreement, a reference to the Issuer Trustee is a reference to the Issuer Trustee in its capacity as trustee of the Trust only, and in no other capacity. Any reference to the assets, business, property or undertaking of the Issuer Trustee is a reference to the Issuer Trustee in that capacity only.

The Westpac Parties and the Issuer Trustee hereby agree with the Underwriters as follows:

Westpac shall pay U.S.$XXXXXX (the “Commission”) to the Underwriters on the Closing Date in immediately available funds by official bank check or checks or wire transfer to a bank account or accounts directed by the Representative.

(ii) the Issuer Trustee will notify the Representative promptly after it becomes actually aware of any matter which would make any of its representations, warranties, agreements and indemnities herein untrue if given at any time prior to payment being made to the Issuer Trustee on the Closing Date and take such steps as may be reasonably requested by the Representative to remedy and/or publicize the same;

(iii) the Issuer Trustee will pay any stamp duty or other issue, transaction, value added or similar tax, fee or duty (including court fees) in relation to the execution of, or any transaction carried out pursuant to, the Agreements or in connection with the issue and distribution of the Notes or the enforcement or delivery of this Agreement;

(iv) the Issuer Trustee will use all reasonable endeavors to procure satisfaction on or before the Closing Date of the conditions referred to in Section 6 below and, in particular (a) the Issuer Trustee shall execute those of the Basic Documents not executed on the date hereof on or before the Closing Date, and (b) the Issuer Trustee will assist the Representative to make arrangements with DTC, Euroclear and Clearstream Luxembourg concerning the issue of the Notes and related matters;

(v) the Issuer Trustee will procure that the charges created by or contained in the Security Trust Deed are registered within all applicable time limits in all appropriate registers;

7.	Indemnification and Contribution.

(a) Each of Westpac and the Trust Manager, jointly and severally, agrees to indemnify and hold harmless each Underwriter, each affiliate of an Underwriter which assists such Underwriter in the distribution of the Securities, and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, (collectively the “Underwriter Parties”) from and against any and all losses, claims, damages and liabilities (including, without limitation, the legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or in the Prospectus (as amended and supplemented if the Trust Manager shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except (i) to the extent any losses, claims, damages or liabilities arise as a result of any information under the heading “Prepayment and Yield Considerations”, except to the extent of any errors in the information under such heading that are caused by errors in pool information, (ii) insofar as such losses, claims, damages or liabilities are caused by any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information relating to any Underwriter furnished to the Trust Manager in writing by such Underwriter through the Representative expressly for use therein or (iii) that such indemnity with respect to the Prospectus shall not inure to the benefit of any Underwriter Party from whom the person asserting any such loss, claim, damage or liability purchased the Notes if such person did not receive a copy of the Prospectus (as amended or

supplemented) to correct the untrue statement or omission of a material fact, at or prior to the confirmation of the sale of such Notes to such person in any case where such delivery is required by the Securities Act; and the Trust Manager has furnished the Underwriter Party an amended or supplemented Prospectus in such quantity and with sufficient time to make the required delivery to such person;

(b) To the extent that any payment of damages by Westpac pursuant to subsection 7(a) above is determined to be a payment of damages pursuant to “Guidance Note AGN 120.3 - Purchase and Supply of Assets (including Securities Issued by SPVs)”, such payment shall be subject to the conditions specified in Paragraph 15 therein.

(c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Trust Manager, its directors, its officers who sign the Registration Statement, the Issuer Trustee and Westpac and each person who controls any of the Westpac Parties or the Issuer Trustee within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Westpac Parties to each Underwriter, but only with reference to information relating to any Underwriter furnished to the Trust Manager in writing by such Underwriter through the Representative expressly for use in the Registration Statement, the Prospectus, or any amendment or supplement thereto, it being understood and agreed that the only such information furnished by any Underwriter consists of the information contained in the third, sixth (excluding the following four bullet point paragraphs) and seventh paragraphs under the caption “Plan of Distribution” in the Prospectus.

(d) If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnity may be sought pursuant to Subsections (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnity may be sought (the “Indemnifying Person”) in writing, and the Indemnifying Person, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary, (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person or (iii) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for the Underwriters, each affiliate of any Underwriter which assists such Underwriter in the distribution of the Notes, and such control persons of Underwriters shall be designated in writing by the Representative and any such separate firm for the Trust Manager, its directors, its officers who sign the Registration Statement, and Westpac and such control persons of any of the Westpac Parties shall be

designated in writing by the Trust Manager. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested an Indemnifying Person to reimburse the Indemnified Person for fees and expenses of counsel as contemplated by the third sentence of this subsection (d), the Indemnifying Person agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (a) such settlement is entered into more than 30 days after receipt by such Indemnifying Person of the aforesaid request and (b) such Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release of such Indemnified Person from all liability on claims that are the subject matter of such proceeding.

(e) If the indemnification provided for in subsections (a) or (b) above is unavailable to an Indemnified Person in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such subsection, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Westpac Parties and the Issuer Trustee on the one hand and the Underwriters on the other hand from the offering of the Notes, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Westpac Parties and the Issuer Trustee on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Westpac Parties and the Issuer Trustee on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds from the offering received by the Westpac Parties and the Issuer Trustee and the total underwriting discounts and the commissions received by the Underwriters bear to the aggregate public offering price of the Notes. The relative fault of the Westpac Parties and the Issuer Trustee on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Westpac Parties or the Issuer Trustee or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(f) The Westpac Parties, the Issuer Trustee and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an Indemnified Person as a

result of the losses, claims, damages and liabilities referred to in this subsection (f) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to the respective principal amount of Notes set forth opposite their names in Schedule I hereto, and not joint.

The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(g) The indemnity and contribution agreements contained in this Section 7 and the representations and warranties of the Westpac Parties, the Issuer Trustee and Underwriters set forth in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Westpac Parties or the Issuer Trustee, its officers or directors or any other person controlling the Westpac Parties or the Issuer Trustee and (iii) acceptance of and payment for any of the Notes.

8.	Termination.

Notwithstanding anything herein contained, this Agreement may be terminated in the absolute discretion of the Representative, by notice given to the Trust Manager, if after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by, as the case may be, any of the New York Stock Exchange or the Australian Stock Exchange, (ii) trading of any securities of or guaranteed by any of the Westpac Parties or the Issuer Trustee shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York, Sydney, Australia or London, England shall have been declared by either Federal, New York State, the Commonwealth of Australia or the United Kingdom or related authorities, or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in the judgment of the Representative, is material and adverse and which, in the judgment of the Representative, makes it impracticable to market the Notes on the terms and in the manner contemplated in the Prospectus.

9.	Default of Underwriters.

If on the Closing Date any one or more of the Underwriters shall fail or refuse to purchase Notes which it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Notes which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of

the Notes to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the principal amount of Notes set forth opposite their respective names in Schedule I bears to the aggregate principal amount of Notes set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representative may specify, to purchase the Notes which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the principal amount of Notes that any Underwriter has agreed to purchase pursuant to Section 1 be increased pursuant to this Section 9 by an amount in excess of one-ninth of such principal amount of Notes without the written consent of such Underwriter. If on the Closing Date any Underwriter or Underwriters shall fail or refuse to purchase Notes which it or they have agreed to purchase hereunder on such date, and the aggregate principal amount of Notes with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Notes to be purchased on such date, and arrangements satisfactory to the Representative and the Trust Manager for the purchase of such Notes are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Trust Manager. In any such case either you or the Trust Manager shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and in the Prospectus or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

10.	Expenses Upon Termination.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Westpac Parties or the Issuer Trustee to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason any of the Westpac Parties or the Issuer Trustee shall be unable to perform its obligations under this Agreement or any condition of the Underwriters’ obligations cannot be fulfilled, Westpac agrees to reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and expenses of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

11.	Selling Restrictions.

(a) No offering circular, prospectus or other disclosure document in relation to any Notes has been lodged with the Australian Securities and Investments Commission or the Australian Stock Exchange Limited. Each Underwriter severally (but not jointly) represents and agrees that in connection with the distribution of the Notes:

(i)

it has not, directly or indirectly, offered for issue or sale or invited applications for the issue of or for offers to purchase nor has it sold, the Notes;

(ii)

it will not, directly or indirectly, offer for issue or sale or invited applications for the issue of or for offers to purchase nor will it sell the Notes; and

(iii)

it has not distributed and will not distribute any draft, preliminary or definitive offering circular, or any advertisement or other offering material,

in the Commonwealth of Australia, its territories or possessions (“Australia”) unless:

(A)

the amount payable for the Notes on acceptance of the offer by each offeree or invitee is a minimum amount of A$500,000 (or its equivalent in another currency) (disregarding amounts, if any, lent by the Trust Manager or other person offering the Notes or any associate of them, which will also include for this purpose the Issuer Trustee) or the offer or invitation is otherwise an offer or invitation for which no disclosure is required to be made under Part 6D.2 of the Corporations Act 2001 (Cth) (the “Corporations Act”) as then in effect and the Corporations Regulations made under the Corporations Act as then in effect; and

(B)

the offer, invitation or distribution complies with all applicable laws, regulations and directives in relation to the offer, invitation or distribution and does not require any document to be lodged with the Australian Securities and Investments Commission or the Australian Stock Exchange Limited.

(b) Each Underwriter severally (but not jointly) agrees that, in connection with the primary distribution of the Notes, it will not sell any Notes to any person if, at the time of such sale, the employees of the Underwriter aware of, or involved in, the sale actually knows (but without an obligation on such Underwriter to make any inquiry) or has reasonable grounds to suspect, that as a result of such sale, such Notes or any interest in such Notes were being, or would later be acquired (directly or indirectly) by an Offshore Associate of the Issuer Trustee (other than in the capacity of a dealer, manager or underwriter in relation to a placement of the Notes or in the capacity of a clearing house, custodian, funds manager or responsible entity of an Australian scheme).

For purposes of this Section 11 an “Offshore Associate” of the Issuer Trustee means an “associate” within the meaning of Section 128F of the Tax Act that is either a non resident of Australia that does not acquire the Notes in carrying on business at or through a permanent establishment in Australia; or a resident of Australia that acquires the Notes in carrying on a business at or through a permanent establishment outside Australia.

Notwithstanding the foregoing, for purposes of this Section 11, an Underwriter will be considered to have actual knowledge or reasonable grounds to suspect that an entity is an Offshore Associate of the Issuer Trustee only if that entity is identified on the lists that are to be provided to the Representative by the Issuer Trustee and Westpac (collectively, the “List”).

(c) Each Underwriter (severally, not jointly) agrees that it must offer the Notes for which it subscribes for sale within 30 days of the issue of those Notes. Such offer must only be by one of the following means (or a combination thereof):

(1)

as a result of negotiations being initiated by the Underwriter in electronic form on Reuters or the electronic information system made available to its subscribers by Bloomberg, L.P., specifying in such offer the name of the issuer and the price at which the Notes are offered for sale; or

(2)

to at least 10 persons each of whom was carrying on a business of providing finance, investing in or dealing in securities, in the course of operating in financial markets who was not actually known (but without an obligation on such Underwriter to make any inquiry) or reasonably suspected by the employees of each Underwriter acting in relation to the sale to be an associate (as defined in Section 128F of the Tax Act) of any other person covered by this sub-paragraph (2); or

(3)

to at least 100 persons who it would be reasonable to regard as either having acquired instruments similar to the Notes in the past or as likely to be interested in acquiring Notes.

Each Underwriter (severally, not jointly) agrees that it will provide the Issuer Trustee (within five Business Days of the offer of such Notes by it) a written statement which sets out the details of the relevant offer.

Each Underwriter (severally, not jointly) agrees to co-operate with reasonable requests from the Issuer Trustee for information for the purposes of assisting the Issuer Trustee to demonstrate that the public offer test under Section 128F of the Tax Act has been satisfied, provided that no Underwriter shall be obliged to disclose:

(1)

the identity of the purchaser of any Note,

(2)

any information from which such identity might/would be capable of being ascertained,

(3)

any information the disclosure of which would be contrary to or prohibited by any relevant law, regulation or directive, or

(4)

any information or documentation after a period of 4 years from the lodgment of the income tax return by the Trustee for the financial year ending September 30, 2005.

(d) Each Underwriter (severally and not jointly) acknowledges that no representation is made by the Issuer Trustee or any Westpac Party that any action has been or will be taken in any jurisdiction outside the United States by the Issuer Trustee or any Underwriter that would permit a public offering of the Notes, or possession or distribution of the Prospectus or any other offering material, in any country or jurisdiction where action for that purpose is required. Each Underwriter (severally and not jointly) will comply with all applicable securities laws and regulations in each jurisdiction in which it purchases, offers, sells or delivers Notes or has in its

possession or distributes the Prospectus or any other offering material, in all cases at its own expense.

(e) Each Underwriter (severally and not jointly) agrees that:

(i)

it has not offered or sold and will not offer or sell any Notes to persons in the United Kingdom prior to the expiry of a period of six months from the date of issue of the Notes except to persons whose ordinary activities involve them in acquiring, holding, managing or disposing of investments (as principal or agent) for the purposes of their businesses or otherwise in circumstances which have not resulted and will not result in an offer to the public in the United Kingdom within the meaning of the Public Offers of Securities Regulations 1995, as amended (the “UK Regulations”);

(ii)

it has complied with and will comply with all applicable provisions of the UK Regulations and the Financial Services and Markets Act 2000 (the “FSMA”) with respect to anything done by it in relation to the Notes in, from or otherwise involving the United Kingdom; and

(iii)

it has only communicated or caused to be communicated, and will only communicate or cause to be communicated, any invitation or inducement to engage in investment activity (within the meaning of section 21 of the FSMA) received by it in connection with the issue or sale of such Notes in circumstances in which section 21(1) of the FSMA does not apply to the Issuer Trustee.

12.	Certain Matters Relating to the Issuer Trustee.

The Issuer Trustee enters into this Agreement 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 Issuer Trustee only to the extent to which it can be satisfied out of assets of the Trust out of which the Issuer Trustee is actually indemnified for such liability. This limitation of the Issuer Trustee’s liability applies despite any other provisions of this Agreement 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 this Agreement or the Trust.

The parties other than the Issuer Trustee may not sue the Issuer 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 other similar person to the Issuer Trustee or prove in any liquidation, administration or arrangements of or affecting the Issuer Trustee.

The provisions of this clause 12 shall not apply to any obligation or liability of the Issuer Trustee to the extent that it is not satisfied because under the Master Trust Deed or by operation of law there is a reduction in the extent of the Issuer Trustee’s indemnification out of the assets of the Trust as a result of the Issuer Trustee’s fraud, negligence or breach of trust.

It is acknowledged that the Trust Manager, the Servicer, the Currency Swap Provider, the Note Trustee, the Principal Paying Agent, the other Paying Agents and the Agent Bank (each, a “Relevant Party”) are responsible under the Transaction Documents (as defined in the Master Trust Deed) for performing a variety of obligations relating to the Trust. No act or omission of the Issuer Trustee (including any related failure to satisfy its obligations under the Transaction Documents) will be considered fraud, negligence or breach of trust of the Issuer Trustee for the purpose of this Agreement 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 Issuer Trustee and for whom the Issuer Trustee is responsible under the relevant Transaction Document, but excluding any Relevant Party) to fulfill its obligations relating to the Trust or by any other act or omission of a Relevant Party or by any other person who provides services in respect of the Issuer Trustee (other than a person who has been delegated or appointed by the Issuer Trustee and for whom the Issuer Trustee is responsible under the Transaction Documents, but excluding any Relevant Party). No attorney, agent, receiver, or receiver and manager appointed in accordance with this agreement or any other Transaction Document (including a Relevant Party) has authority to act on behalf of the Issuer Trustee in a way which exposes the Issuer 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 Issuer Trustee for the purpose this Agreement, if the Issuer Trustee has exercised reasonable care in the selection and supervision of such a person.

13.	Successors.

This Agreement shall inure to the benefit of and be binding upon the Westpac Parties, the Issuer Trustee, the Underwriters, each affiliate of any Underwriter which assists such Underwriter in the distribution of the Notes, any controlling persons referred to herein and their respective successors and assigns. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any other person, firm or corporation any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. No purchaser of Notes from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

14.	Actions by Representative; Notices.

Any action by the Underwriters hereunder may be taken by the Representative alone on behalf of the Underwriters, and any such action taken by the Representative shall be binding upon the Underwriters. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be given to the Representative at Deutsche Bank Securities Inc., 60 Wall Street, New York, NY 10005, Attention: Timothy O’Toole. Notices to the Trust Manager shall be given to it at c/o Westpac Banking Corporation, Level 6, 60 Martin Place, Sydney, NSW 2000, Attention: Senior Manager, Securitisation; to the Issuer Trustee shall be given to it at c/o Westpac Banking Corporation, Level 13, Chifley Tower, 2 Chifley Square, Sydney, NSW 2000, Australia, Attention: Manager, Trustee Securitisation; and to Westpac shall be given to it at Level 6, 60 Martin Place, Sydney, NSW 2000, Attention: Senior Manager, Securitisation.

This Agreement shall be governed by and construed in accordance with the laws of the State of New York, without giving effect to the conflicts of laws provisions thereof.
