 The 28th Battalion came into existence on 16 April 1915 when it was raised at Blackboy Camp, in Western Australia.Formed as part of the Australian Imperial Force (AIF), an all volunteer formation raised for overseas service during the First World War, the 28th Battalion's first batch of volunteers came from personnel who had originally been allocated to the 24th Battalion.The 24th was being raised at Broadmeadows in Victoria, and it had been intended that the 24th would be raised from all states of Australia with recruits travelling to Victoria to form the unit, but the higher than expected number of volunteers at Broadmeadows at the time meant that the 24th was raised as a Victorian battalion, and the Western Australians, who had been intended to form a sub unit within the 24th, were reallocated to the 28th which was subsequently raised mainly from Western Australian recruits.
