About: 31st Brigade (Australia)

The 31st Brigade was a formation of the Australian Army during World War II. Raised in January 1942, amidst concerns of a Japanese invasion of Australia, the brigade was tasked with defending the eastern New South Wales coast around Botany Bay and Cronulla. Initially consisting of just two infantry battalions, after several months a third battalion was assigned to bring it up to strength. The formation was only short-lived and was disbanded in September 1942, having never seen combat, with its battalions being reassigned to other formations.
