The Australian Staff Corps was a small corps of Regular Army officers who were trained in staff duties and who were largely responsible for the training of the Militia, Australia’s part-time military force, during the inter-war period and in the early years following the Second World War.

[1] The corps was established on 1 October 1920,[2] in the aftermath of the First World War following the demobilisation of the Australian Imperial Force, when Australia's part-time military forces were reorganised to re-assume the main responsibility for the nation's defences.

These personnel were posted to Militia units as part of a small Regular training and administration cadre.

[5] In the post Second World War period, the strategic imperatives of the Cold War resulted in the Regular Army taking primacy over part-time forces, and the training of part-time soldiers moved towards a more centralised scheme.

Amidst these and other changes the Australian Staff Corps was finally removed from the Order of Precedence in 1983.
