1914 in Australia was dominated by the outbreak of World War I. Andrew Fisher, who became Prime Minister a month after Australia entered the war vowed that Australia would "stand beside our own to help and defend Britain to the last man and the last shilling."^[1] In 1914, the Australian war effort was dominated by recruiting and equipping a force to fight overseas.

The southern winter rainfall zone of the continent suffered its worst rainfall failure until 1982. This led to record low wheat yields and exacerbated the problems caused by outbreak of World War I.
