Anzac Commemorative Medallion
The Anzac Commemorative Medallion was instituted 1967. It was awarded to surviving members of the Australian forces who served on the Gallipoli Peninsula, or in direct support of the operations from close off shore, at any time during the period from the first Anzac Day in April 1915 to the date of final evacuation in January 1916.
Next of kin, or other entitled persons, are entitled to receive the medallion on behalf of their relatives if the medallion has not been issued.

The medallion is cast in bronze and is approximately 75 millimetres high and 50 millimetres wide. The obverse of the medallion depicts Simpson and his donkey carrying a wounded soldier to safety. It is bordered on the lower half by a laurel wreath above the word ANZAC.
The reverse shows a map in relief of Australia and New Zealand superimposed by the Southern Cross. The lower half is bordered by New Zealand fern leaves. The name and initials of the recipient is engraved on the reverse. The medallion is issued in a presentation box.

Surviving members were also issued with a lapel badge in the form of a small replica of the medallion to recognise their Gallipoli service. This badge is not issued to other applicants.
