World War II
Global conflict during the years 1939–1945. Australia's involvement in the second world war began with Prime Minister Robert Menzies' radio announcement on 3 September 1939 that the country was at war, and ended with Japan's unconditional surrender on 14 August 1945. As a member of the British Commonwealth, Australia fought with the alliance of powers known as the Allies (Great Britain, France, United States of America, the Soviet Union and China) against the Axis powers (Germany, Japan, Italy). More than a million Australians served, and for the first time the country came under direct military attack.
