The Australian 4th Division was formed in the First World War during the expansion of the Australian Imperial Force (AIF) infantry brigades in February 1916. In addition to the experienced 4th Brigade were added the new 12th and 13th Brigades. From Egypt the division was sent to France, where it took part in the fighting on the Western Front during 1916–1918. After the war ended, the AIF was demobilised and the division was dissolved.

Following the war, the brigade formed part of the 3rd Division, however, it was later reallocated to the 2nd Division, where it serves as a Reserve combined-arms formation including units and personnel from all corps of the Army including armoured, infantry, artillery, engineers, signals and ordnance.
