The "Knight of the Order of Australia" was an honor awarded to individuals for exceptional service to the nation. Established in 1975, it recognized contributions in various fields, including community service, arts, and public service. The title was part of the broader Order of Australia, which includes different levels of awards. In 1986, the Australian government discontinued the title of knight and dame, focusing instead on the existing awards within the Order of Australia. Today, the highest honor within this order is the Companion of the Order of Australia, which continues to celebrate outstanding achievements and contributions to Australian society.
