The Order of Australia is an Australian honour that recognises Australian citizens and other persons for outstanding achievement and service. It was established on 14 February 1975 by Elizabeth II, Queen of Australia, on the advice of then prime minister Gough Whitlam. Before the establishment of the order, Australians could receive British honours, which continued to be issued in parallel until 1992.
Appointments to the order are made by the governor-general, "with the approval of The Sovereign", according to recommendations made by the Council for the Order of Australia. Members of the government are not involved in the recommendation of appointments, other than for military and honorary awards.
