Dear Sir / Madam

Appendix 3Y – Director’s Interest Notice for Mr Brian Hartzer, Managing Director and Chief Executive
Officer

Please find attached an Appendix 3Y – Change of Director’s Interest Notice in relation to Westpac Banking
Corporation (Westpac) security interests held by Mr Hartzer.

Following an internal review it was noted that due to an administrative oversight, a notice to ASX Limited (ASX)
had not been lodged following the lapse of 50,000 share rights consistent with the terms of the Westpac Long
Term Incentive (LTI) Plan on 11 October 2017. A further 45,284 of Mr Hartzer’s share rights have
subsequently lapsed on 2 November 2017 consistent with the terms of the LTI Plan.

As indicated in the Appendix 3Y, following the transactions Mr Hartzer holds relevant interests in 77,427 fully
paid ordinary shares and 569,426 share rights.

The monitoring process for share rights will be further enhanced to prevent such an error reoccurring. Westpac
is confident that the systems it has in place to keep the market fully informed of Directors’ transactions in
Westpac securities remain robust.



Yours sincerely,



Tim Hartin
Company Secretary
