In 1914, approximately 6,000 Imperial Reservists—men who had previously served in British regiments, emigrated and were living in Australia. Upon the outbreak of war in August 1914, these men were recalled to serve with their old British units. Many of these reservists sailed in the first troop convoy to leave Australia in November 1914. These men were distinct from the newly formed Australian Imperial Force (AIF), which was raised in August 1914 for service under the Australian government, although many Australian citizens volunteered for service.British Imperial Reservists (IRs) who were living in Australia were recalled to the British Expeditionary Forces in World War One (WWI).
