World War II cost thousands of Australian lives and consumed a large portion of the national income. During the war, 27,073 members of the Australian military were either killed, died of wounds or died while prisoners of war. Of these, 9,572 were killed in the war against Germany and Italy and 17,501 in the war against Japan. Prisoners of war held by the Japanese made up nearly half of Australia's deaths in the Pacific. At least 386 Australian civilian seamen were killed during the war. Total Australian war expenditure was £2,949,380,000 and at its peak in 1942–43, military costs accounted for 40.1 percent of national income.
