1st Australian Task Force

The 1st Australian Task Force (1 ATF) was a brigade-sized formation which commanded Australian and New Zealand Army units deployed to South Vietnam between 1966 and 1972. 1 ATF was based in a rubber plantation at Nui Dat, north of Ba Ria in Phuoc Tuy Province and consisted of two and later three infantry battalions, with armour, aviation, engineers and artillery support. At the Battle of Long Tan on 18 August 1966, units of 1 ATF defeated a Viet Cong force of at least regimental strength. While the task force was primarily responsible for securing Phuoc Tuy Province, its units, and the Task Force Headquarters itself, occasionally deployed outside its Tactical Area of Responsibility including during Operation Coburg and the Battle of Coral–Balmoral in 1968. Other significant actions included Hat Dich in late-December 1968 and early 1969, Binh Ba in June 1969, and Long Khanh in June 1971. 1 ATF was withdrawn in late 1971.
