If you attend the meeting, please bring this barcoded form with you.

Alternatively, the Form of Proxy can be lodged in accordance with the instructions in the notice of meeting.

We have enclosed a form for those who cannot attend the meeting but would like to submit questions on any shareholder matters that may be relevant to the Annual General Meeting. I invite you to submit any questions you may have on this enclosed form and return it with the Form of Proxy. While time will undoubtedly not permit me to address all the questions submitted, I will endeavour to address as many of the more frequently raised shareholder matters during the course of the Annual General Meeting.

A live webcast of the presentation will be broadcast on the Bank’s website through the Shareholder Centre at http://www.commbank.com.au/shareholder/annualgeneralmeeting. An archive of the webcast will be available at the same web address within a day. This will enable you to hear or read the responses to the questions raised on the returned forms and during the meeting.

Any body corporate holder of Commonwealth Bank shares, or any body corporate appointed as a proxy, wishing to appoint a person to act as its representative at the meeting may do so by providing that person with a letter, executed in accordance with the body corporate’s constitution, authorising him or her as the body corporate’s representative.

The Notice of Meeting commences on page 4, listing the items to be considered at the meeting. Background information on items 2 and 3 is contained in the Explanatory Memorandum on pages 6 to 10.

Resolution 3 is a non-binding resolution that shareholders adopt the Remuneration Report which is contained on pages 49 to 68 in the full Annual Report and on pages 31 to 50 of the concise Annual Report. I would encourage you to review the detailed account of the Bank’s remuneration policy as set out in this report.
