The "Brisbane Line" was a defence proposal supposedly formulated during World War II to concede the northern portion of the Australian continent in the event of an invasion by the Japanese. Although a plan to prioritise defence in the vital industrial regions between Brisbane and Melbourne in the event of invasion had been proposed in February 1942, it was rejected by Labor Prime Minister John Curtin and the Australian War Cabinet. An incomplete understanding of this proposal and other planned responses to invasion led Labor minister Eddie Ward to publicly allege that the previous government (a United Australia Party-Country Party coalition under Robert Menzies and Arthur Fadden) had planned to abandon most of northern Australia to the Japanese. Ward continued to promote the idea during late 1942 and early 1943, and the idea that it was an actual defence strategy gained support after General Douglas MacArthur referred to it during a press conference in March 1943, where he also coined the term "Brisbane Line". Ward initially offered no evidence to support his claims, but later claimed that the relevant records had been removed from the official files. A Royal Commission concluded that no such documents had existed, and the government under Menzies and Fadden had not approved plans of the type alleged by Ward. The controversy contributed to Labor's win in the 1943 federal election, although Ward was assigned to minor portfolios afterward. Ward's allegations In October 1942, Labor politician Eddie Ward, the Minister for Labour and National Service under Prime Minister John Curtin, alleged that the preceding government under Prime Minister Robert Menzies (and his successor, Prime Minister Arthur Fadden) had prepared plans to abandon the majority of the continent as soon as the Japanese invaded, and concentrate defensive efforts on the south-eastern region. Ward had apparently been leaked the information by a Major working in the Secretary for Defence Office. A memorandum had been submitted to the Australian War Cabinet in February 1942 (after Menzies, Fadden, and the United Australia Party-Country Party coalition had moved to Opposition), where the General Officer Commanding-in-Chief of the Home Forces, Lieutenant-General Iven Mackay, had advocated that in the event of an invasion, the majority of available Australian forces be concentrated in the area between Brisbane and Melbourne, where most of the nation's industrial capability was located. Mackay had previously been instructed to prioritise the regions around Sydney and Newcastle, with Darwin as
