Dear Sir / Madam

ASIC Corporations (Regulatory Capital Securities) Instrument 2016/71 ("Instrument")

1. Westpac issued the Notes today. Offers of the Notes do not require disclosure to investors under Part 6D.2 of the Act.

2. The terms and conditions of the Notes ("Conditions") are described on pages 7 to 10 of the Product Disclosure Statement dated 26 July 2016 relating to the offer of the Notes in New Zealand ("PDS") and set out in Schedule 1 to the Westpac NZD Subordinated Notes Supplemental Deed Poll dated 25 July 2016 which, together with the Master Deed Poll dated 25 July 2016, constitutes the Notes ("Deed Poll"). The PDS was released to the Australian Securities Exchange ("ASX") in an announcement by Westpac on 26 July 2016 ("Westpac NZD Subordinated Notes Offer") and may be viewed on www.asx.com.au. The Conditions (extracted from Schedule 1 to the Deed Poll) are included in Annex A to the Schedule to this notice.

3. The Notes will be treated as Tier 2 Capital under the Basel III capital adequacy framework as implemented in Australia by the Australian Prudential Regulation Authority ("APRA").

4. If APRA determines that Westpac is or would become non-viable, the Notes may be:

5. Converted into fully paid ordinary shares in the capital of Westpac; or

6. immediately and irrevocably Written-off (and rights attaching to the Notes terminated) if for any reason Conversion does not occur within five ASX Business Days of APRA notifying Westpac of the determination,

   in accordance with the Conditions.

7. In order to enable ordinary shares in the capital of Westpac issued on Conversion to be sold without disclosure under Chapter 6D of the Act, Westpac has elected to give this notice under section 708A(12H)(e) of the Act as inserted by the Instrument.1 The Conditions and the information in the attached Schedule are included in, and form part of, this notice.

   1 Westpac notes that, at its request, the Australian Securities and Investments Commission ("ASIC") made a further modification (under ASIC Instrument 16-0729) to the definition of "technical relief instrument" in section 9 of the Act as modified by ASIC Corporations (Disregarding Technical Relief) Instrument 2016/73, which ensures that Westpac is able to satisfy the definition of "continuously quoted securities" in section 9 of the Act for the purposes of the Instrument.

8. Westpac confirms that:

9. the information in this notice remains current as at today's date;

10. this notice complies with section 708A of the Act, as notionally modified by the Instrument; and

    Westpac Banking Corporation NOT FOR DISTRIBUTION OR RELEASE IN THE UNITED STATES

    This market announcement does not constitute an offer to sell or the solicitation of an offer to buy any securities in the United States or any other jurisdiction. The securities offered have not been and will not be registered under the U.S. Securities Act of 1933, as amended, and may not be offered or sold in the United States or to, or for the account or benefit of, U.S. persons absent registration or an applicable exemption from registration.

    SCHEDULE
14. Effect on Westpac of the offer of the Notes

    The issuance of the Notes raises Tier 2 Capital to satisfy Westpac's regulatory capital requirements and maintain the diversity of Westpac's sources and types of capital funding.

    The proceeds from the issue of the Notes will be used for general business purposes. Those proceeds, less the costs of the issue, will be classified as loan capital in the financial statements of Westpac. The issue of the Notes will not have a material impact on Westpac's financial position.

    The proceeds of the issue, less the costs of the issue, will increase Westpac's total capital ratio on a Level 2 basis by 0.1%.

15. Rights and liabilities attaching to the Notes

    The rights and liabilities attaching to the Notes are described on pages 7 to 10 of the PDS and are set out in the Conditions, which form Annex A to this Schedule.

    For the purposes of Condition 3.3 of the Notes, the Margin (determined under the Bookbuild) is 2.60%. The Interest Rate for the Notes for each Interest Period that ends before the First Optional Redemption Date will therefore be 4.6950% per annum, being the sum of the 5 Year Swap Rate on the Rate Set Date and the Margin. The Margin is set until the Maturity Date (or an earlier redemption date), although the Interest Rate will be reset on the First Optional Redemption Date (based on the 5 Year Swap Rate on that date).

16. Effect on Westpac of the issue of the ordinary shares if the Notes are required to be Converted2

    A key feature of APRA's requirements for Tier 2 Capital instruments is that they absorb losses at the point of non-viability of the issuer. The Conditions include provisions that require the Notes to be Converted into ordinary shares in the capital of Westpac or Written-off on the occurrence of a Non-Viability Trigger Event. A Non-Viability Trigger Event will occur when APRA notifies Westpac in writing that it believes that relevant non- viability circumstances (as described in the definition of "Non-Viability Trigger Event" in the Conditions) subsist, which could occur at any time.

    If a Non-Viability Trigger Event occurs and Westpac Converts the Notes and issues ordinary shares to Holders, the effect of Conversion on Westpac would be to reduce loan capital by the principal amount, less any unamortised costs of the issue, of the Notes being Converted and increase Westpac's shareholders' equity (ordinary share capital) by a corresponding amount. APRA has not provided guidance on when it will consider an entity to be non-viable and there are currently no Australian precedents for this. However, it is likely that APRA will consider an entity to be non-viable when, for example, the entity is suffering from significant financial stress, is insolvent or cannot raise money in the public or private markets.

    The number of ordinary shares issued on Conversion is variable, but is limited to the Maximum Conversion Number. Limiting the number of ordinary shares which may be issued to the Maximum Conversion Number means that Holders may receive a number of ordinary shares that have a market value that is significantly less than the principal amount of the Notes.

    The Maximum Conversion Number is calculated based on a VWAP set to reflect 20% of the Issue Date VWAP. The Maximum Conversion Number may be adjusted to reflect a reconstruction, consolidation, division or reclassification or a pro rata bonus issue, of ordinary shares. However, no adjustment will be made to it on account of other transactions which may affect the price of ordinary shares, including for example, rights issues, returns of capital, buy-backs or special dividends.

    The Maximum Conversion Number is 0.1598 Westpac ordinary shares per Note (with a nominal value of NZD1.00), based on the Issue Date VWAP of AUD30.13. If Conversion of any Notes does not occur for any reason within five ASX Business Days after the occurrence of the Non-Viability Trigger Event, the Notes will be Written-off, and all corresponding rights and claims of Holders under the Conditions (including to payments of interest and the repayment of principal and to be issued with the relevant number of ordinary shares in

    2 If, in accordance with the Conditions, Westpac is replaced by an Approved Successor as debtor of the Notes and the issuer of ordinary shares, Notes may be converted into fully paid ordinary shares in the capital of an Approved Successor in accordance with the Conditions. This notice also enables ordinary shares in the capital of an Approved Successor which is a NOHC for the purposes of the Banking Act 1959 (Cth) issued on Conversion to be sold without disclosure under Chapter 6D of the Act. Refer to the Conditions and the Instrument for further information.

    respect of such Notes) will be immediately and irrevocably Written-off with effect upon the Non-Viability Trigger Event Date and investors will lose all or some of their investment.

17. Rights and liabilities attaching to ordinary shares in the capital of Westpac

The ordinary shares in the capital of Westpac are admitted to trading on ASX. The rights attaching to the ordinary shares in the capital of Westpac are set out in the Act and the Constitution.
