The 1st Australian Civil Affairs Unit (1 ACAU) was raised in 1967 to coordinate the Australian Army's contribution to the US and allied Pacification Program during the Vietnam War, operating in Phuoc Tuy Province. Although other Australian units also conducted civic action projects in South Vietnam at various times, 1 ACAU had the primary responsibility for them once it was deployed. It was withdrawn from South Vietnam in November 1971.
