The 1st Armoured Division was an armoured formation of the Australian Army, raised in 1941 as part of the Second Australian Imperial Force (AIF) during World War II. While the Division was originally to be deployed to North Africa in late 1941, it was retained in Australia following the outbreak of the Pacific War. The 1st Armoured Division formed a key element of Australia's defences against a feared Japanese invasion and was disbanded in Western Australia in September 1943. History Formation The decision to form the 1st Armoured Division was inspired by the success of mass tank tactics in Europe during the early stages of World War II. The Australian War Cabinet approved the formation of an armoured division in July 1940, and 1st Armoured Division was established on 1 July 1941, under the command of Major General John Northcott. The Australian Armoured Corps was established at the same time, with the corps being formally gazetted on 9 July 1941. The Division was established with two armoured brigades, 1st and 2nd, each of three armoured regiments. These were supported by various corps troops including an armoured car regiment, a motor regiment (converted from a light horse formation), engineers, a field artillery regiment, an anti-tank battery, and a logistics support group. On paper, each armoured regiment was to be equipped with 10 scout cars, 46 cruiser tanks, and six support tanks; while the motor regiment was to be established with 14 scout cars and 44 Universal Carriers, and the armoured car regiment 12 scout cars and 58 armoured cars. During its early existence, the division faced several key challenges. The formation of an armoured division involved a massive expansion of Australia's armoured forces, so the great majority of the division's officers and soldiers had to be trained from scratch in newly established armoured warfare schools. This process was greatly complicated by the limited number of tanks available to the division, with the entire division having only eight light and 10 cruiser tanks by December, and having to utilise 30 Universal Carriers for training. While the number of tanks available to the division slowly increased, it did not receive its full allocation until May 1942. Defence of Australia Prior to the commencement of hostilities with Japan the 1st Armoured Division had been scheduled to deploy to the Middle East where it would be fully equipped and complete its training: the 1st Armoured
