On 29 April 1965 the Australian Government announced the commitment of an Australian battalion to South Vietnam. Prior to the public announcement, discussions had taken place in Hawaii as to the nature of any future commitment in Vietnam. The staff talks, held early May to late April, were between the American Commander-in-Chief Pacific Command, Admiral U.S.G. Sharp Jr, an Australian delegation led by Air Chief Marshal Sir Frederick Scherger, and a New Zealand delegation headed by the Chief of the New Zealand Defence Staff, Admiral Sir Peter Phipps. The participants discussed broad American strategy and possible options as to where any future Australian and New Zealand forces could be deployed within the overall American design. Sharp strongly supported the concept of American forces being deployed in enclaves. He believed that the mere existence of American forces within these enclaves would deprive the North Vietnamese Government of an opportunity for victory and thus encourage them to begin negotiations. If the Australians and New Zealanders did deploy in an enclave, the Americans would provide all combat support capabilities (armour, artillery and air support) as well as the necessary logistic support.
