The Australian 4th Division was formed in the First World War during the expansion of the Australian Imperial Force infantry brigades in February 1916. In addition to the experienced 4th Brigade (previously in the original New Zealand and Australian Division) were added the new 12th and 13th Brigades (spawned from the battalions of the 4th and 3rd Brigades respectively). From Egypt the division was sent to France.

After the war ended and the AIF was demobilised, the 4th Division name was revived and assigned to an Australian Citizens Military Forces (reserve) unit.
