The 3rd Armoured Division was an armoured unit of the Australian Army during World War II. Originally raised in 1921 as the 1st Cavalry Division, the formation had been converted into a motor division in early 1942, before adopting the armoured designation in November 1942. A Militia formation, the division undertook garrison duties in New South Wales and then Queensland and did not see combat before being disbanded in late 1943 and early 1944.
