During WWII, Australia's Dominion status meant that it was automatically at war when Britain declared war on Germany in September 1939. However, Australia's attitude was relatively nonchalant, adopting a ‘business as usual’ approach. The level of enthusiasm for the war effort was not as high as in WWI. In the first four months, only 30,000 men enlisted for the Second Australian Imperial Force (AIF), half the number in WWI. Enlistments saw an increase after Germany conquered France.
