on the course of the conflict.[75]Withdrawal of Australian forces, 1970–1973[edit]
The Australian withdrawal effectively commenced in November 1970. As a consequence of the overall US strategy of Vietnamization and with the Australian government keen to reduce its own commitment to the war, 8 RAR was not replaced at the end of its tour of duty. 1 ATF was again reduced to just two infantry battalions, albeit with significant armour, artillery and aviation support remaining.[76] The Australian area of operations remained the same however, with the reduction in forces only adding further to the burden on the remaining battalions.[76] Regardless, following a sustained effort by 1 ATF in Phước Tuy Province between September 1969 and April 1970, the bulk of communist forces had become inactive and had left the province to recuperate.[77] By 1971 the province had been largely cleared of local VC forces, who were now increasingly reliant on reinforcements from North Vietnam. As a measure of some success, Highway 15, the main route running through Phước Tuy between Saigon and Vũng Tàu, was open to unescorted traffic. Regardless, the Viet Cong maintained the ability to conduct local operations.[59] Meanwhile, the AATTV had been further expanded, and a Jungle Warfare Training Centre was established in Phước Tuy Province first at Nui Dat then relocated to Van Kiep.[78] In November 1970, the unit's strength peaked at 227 advisors.[79][80]https://upload.wikimedia.org/wikiped..._Vietnam_2.jpg

Australian combat forces were further reduced during 1971.[2] The Battle of Long Khánh on 6–7 June 1971 took place during one of the last major joint US-Australian operations, and resulted in three Australians killed and six wounded during heavy fighting in which an RAAF UH-1H Iroqouis was shot down.[81]
On 18 August 1971, Australia and New Zealand decided to withdraw their troops from Vietnam, with the Australian prime minister, William McMahon, announcing that 1 ATF would cease operations in October, commencing a phased withdrawal.[82][83] The Battle of Nui Le on 21 September proved to be the last major battle fought by Australian forces in the war, and resulted in five Australians killed and 30 wounded.[84] Finally, on 16 October Australian forces handed over control of the base at Nui Dat to South Vietnamese forces, while the main body from 4 RAR—the last Australian infantry battalion in South Vietnam—sailed for Australia on board HMAS Sydney on 9 December 1971.[85] Meanwhile, D Company, 4 RAR with an assault pioneer and mortar section and a detachment of APCs remained in Vũng Tàu to protect the task force headquarters and 1 ALSG until the final withdrawal of stores and equipment could be completed, finally returning to Australia on 12 March 1972.[86]Australian advisors continued to train Vietnamese troops however, until the announcement by the newly elected Australian Labor government of Gough Whitlam that the remaining advisors would be withdrawn by 18 December 1972.
It was only on 11 January 1973 that the Governor-General of Australia, Paul Hasluck, announced the cessation of combat operations against the communists.[2] Whitlam recognised North Vietnam, which welcomed his electoral success.[87] However, Australian troops remained in Saigon guarding the Australian embassy until 1 July 1973.[2] The withdrawal from Vietnam meant that 1973 was the first time since the beginning of World War II in 1939 that Australia's armed forces were not involved in a conflict somewhere in the world.[2] In total approximately 60,000 Australians—ground troops, air-force and naval personnel—served in Vietnam between 1962 and 1972. 521 died as a result of the war and over 3,000 were wounded.[3] 15,381 conscripted national servicemen served from 1965 to 1972, sustaining 202 killed and 1,279 wounded.[88] In addition there were six Australians listed as missing in action, although these men are included in the list of Australians killed in action and the last of their remains were finally located and returned to Australia in 2009.[89][90] Between 1962 and March 1972 the estimated cost of Australia's involvement to the war in Vietnam was $218.4 million.[91

In March 1975 the Australian Government dispatched RAAF transport aircraft to South Vietnam to provide humanitarian assistance to refugees fleeing the North Vietnamese Ho Chi Minh Campaign. The first Australian C-130 Hercules arrived at Tan Son Nhat Airport on 30 March and the force, which was designated 'Detachment S', reached a strength of eight Hercules by the second week of April. The aircraft of detachment S transported refugees from cities near the front line and evacuated Australians and several hundred Vietnamese orphans from Saigon to Malaysia. In addition, they regularly flew supplies to a large refugee camp at An Thoi on the island of Phú Quốc.[92] The deteriorating security situation forced the Australian aircraft to be withdrawn to Bangkok in mid-April, from where they flew into South Vietnam each day. The last three RAAF flights into Saigon took place on 25 April, when the Australian embassy was evacuated. While all Australians were evacuated, 130 Vietnamese who had worked at the embassy and had been promised evacuation were left behind.[93] Whitlam later refused to accept South Vietnamese refugees following the fall of Saigon to the communists in April 1975, including Australian embassy staff who were later sent to re-education camps by the communists.[94] The Liberals—led by Malcolm Fraser—condemned Whitlam,[95] and after defeating Labor in the 1975 federal election, allowed South Vietnamese refugees to settle in Australia in large numbers.[96]
