Australia's military involvement in the Vietnam War was the longest in duration of any war in Australia's history.
The arrival of the Australian Army Training Team Vietnam (AATTV) in South Vietnam during July and August 1962 was the beginning of Australia's involvement in the Vietnam War. Australia's participation in the war was formally declared at an end when the Governor-General issued a proclamation on 11 January 1973. The only combat troops remaining in Vietnam were a platoon guarding the Australian embassy in Saigon, which was withdrawn in June 1973.
The Australian commitment consisted predominantly of army personnel, but significant numbers of air force and navy personnel and some civilians also took part.
From the time of the arrival of the first members of the Team in 1962 almost 60,000 Australians, including ground troops and air force and navy personnel, served in Vietnam; 521 died as a result of the war and over 3,000 were wounded. The war was the cause of the greatest social and political dissent in Australia since the conscription referendums of the First World War.
