Insignia
The badge of the Order of Australia is a convex disc (gold for AKs, ADs and ACs, gilt for AOs, AMs and OAMs) representing the Golden Wattle flower. At the centre is a ring, representing the sea, with the word 'Australia' below two branches of golden wattle. The whole disc is topped by the Crown of St Edward. The AC badge is decorated with citrines, blue enamelled ring, and enamelled crown. The AO badge is similar, without the citrines. For the AM badge only the crown is enamelled, and the OAM badge is plain. The AK/AD badge is similar to that of the AC badge, but with the difference that it contains at the centre an enamelled disc bearing an image of the Coat of arms of Australia.
The star for knights and dames is a convex golden disc decorated with citrines, with a blue royally crowned inner disc bearing an image of the Coat of arms of Australia.
The ribbon of the Order is blue with a central stripe of golden wattle flower designs; that of the military division has additional golden edge stripes. AKs, male ACs and AOs wear their badges on a necklet; male AMs and OAMs wear them on a ribbon on the left chest. Women usually wear their badges on a bow on the left shoulder, although they may wear the same insignia as males, if so desired.
A gold lapel pin for daily wear is issued with each badge of the Order at the time of investiture; AK/AD and AC lapel pins feature a citrine central jewel, AO and AM lapel pins have a blue enamelled centre, and OAM lapel pins are plain.
The Order's insignia were designed by Stuart Devlin.
