The withdrawal of Australia's forces from South Vietnam began in November 1970, under the Gorton Government, when 8 RAR completed its tour of duty and was not replaced. A phased withdrawal followed, and by 11 January 1973 Australian involvement in hostilities in Vietnam had ceased. Nevertheless, Australian troops from the Australian Embassy Platoon remained deployed in the country until 1 July 1973, and Australian forces were deployed briefly in April 1975, during the Fall of Saigon, to evacuate personnel from the Australian embassy. Approximately 60,000 Australians served in the war; 521 were killed and more than 3,000 were wounded.
