This is a list of Knights and Dames of the Order of Australia.
The Order of Australia is the only Australian order of chivalry, although certain dynastic British orders of chivalry, such as the Order of the Garter, the Order of the Thistle and the Royal Victorian Order, may still be awarded to Australians by the Monarch of Australia. It was established on 14 February 1975 by Queen Elizabeth II on the recommendation of the Prime Minister of Australia, Gough Whitlam, to recognise Australian citizens and other persons for achievement, meritorious service, or for both. At its establishment, the Order of Australia included three grades: Companion (AC), Officer (AO) and Member (AM), and two Divisions: Civil and Military.
On 24 May 1976, the grades of Knight (AK) and Dame (AD), and the Medal of the Order of Australia (OAM), were established by the Monarch on the advice of Prime Minister Malcolm Fraser, and the Civil Division was renamed the General Division. Knight and Dame of the Order of Australia superseded Companion of the Order as the highest grade, however Knight and Dame are only awarded in the General Division of the Order.
Recipients who are not Australian citizens may be appointed Honorary Knights or Dames, although no such appointments have yet been made.
On 14 March 1981 the Queen co-signed Letters Patent amending the Constitution of the Order of Australia to create her son, the Heir to the Australian throne, HRH Charles, Prince of Wales a Knight of the Order of Australia. This procedure was necessary as Prince Charles, not being an Australian citizen, would not otherwise have qualified for a substantive knighthood and would have been eligible only for an honorary award.
Following the 1983 election, Prime Minister Bob Hawke advised the abolition of the Knight and Dame grades. On 3 March 1986, the Monarch co-signed Letters Patent revoking the categories of Knight and Dame – existing Knights and Dames were not affected by this change.
