More than 39,700 were killed or died as prisoners of war, about 8,000 of whom died as prisoners of the Japanese. Australian home front While the Australian civilian population suffered less at the hands of the Axis powers than did other Allied nations in Asia and Europe, Australia nevertheless came under direct attack by Japanese naval forces and aerial bombardments, particularly through 1942 and 1943, resulting in hundreds of fatalities and fuelling fear of Japanese invasion. Axis naval activity in Australian waters also brought the war close to home for Australians. Austerity measures, rationing and labour controls measures were all implemented to assist the war effort. Australian civilians dug air raid shelters, trained in civil defence and first aid, and Australian ports and cities were equipped with anti aircraft and sea defences. The Australian economy was markedly affected by World War II. Expenditure on war reached 37 per cent of GDP by 1943–44, compared to 4 per cent expenditure in 1939–1940. Total war expenditure was £2,949 million between 1939 and 1945. Although the peak of army enlistments occurred in June–July 1940, when more than 70,000 enlisted, it was the Curtin Labor Government, formed in October 1941, that was largely responsible for "a complete revision of the whole Australian economic, domestic and industrial life". Rationing of fuel, clothing and some food was introduced, (although less severely than in Britain) Christmas holidays curtailed, "brown outs" introduced and some public transport reduced. From December 1941, the Government evacuated all women and children from Darwin and northern Australia, and more than 10,000 refugees arrived from South East Asia as Japan advanced. In January 1942, the Manpower Directorate was set up "to ensure the organisation of Australians in the best possible way to meet all defence requirements." Minister for War Organisation of Industry, John Dedman introduced a degree of austerity and government control previously unknown, to such an extent that he was nicknamed "the man who killed Father Christmas". In May 1942 uniform tax laws were introduced in Australia, ending state governments' control of income taxation. "The significance of this decision was greater than any other... made throughout the war, as it added extensive powers to the Federal Government and greatly reduced the financial autonomy of the states." Manufacturing grew significantly because of the war. "In 1939, there were only three Australian firms producing machine tools, but by 1943 there were more than one hundred
