The order of wearing honour and awards is determined by the Governor-General and published from time to time to reflect changes to the honours and awards system.
The most recent order was published on 25 September 2007 and is available from the Awards and Culture Branch of Department of Prime Minister & Cabinet at www.itsanhonour.gov.au
A modified order based on that list, but incorporating recently issued medals (Australian Defence Medal, Afghanistan Medal and Iraq Medal) is included here.
