Australian military districts, October 1939

The 4th Military District was an administrative district of the Australian Army. During the Second World War, the 4th Military District covered all of South Australia, with its headquarters at Adelaide. Around the start of the Second World War, the 4th Military District became part of Southern Command, along with the 3rd and 6th Military Districts in Victoria and Tasmania. This required legislative changes to the Defence Act (1903), and did not come into effect until October 1939.^[1][2]
