After World War II, the Australian military was demobilised. By 1948 this process had been completed and a period of reorganisation began. This resulted in the establishment of a Regular infantry force consisting of a single brigade and two divisions of part-time soldiers in the Citizens Military Force (CMF). There was no room within this structure for the 1st Division and as a result it remained off the Australian Army's order of battle until 1960, when its headquarters was reformed in Sydney, New South Wales, following the implementation of the Pentropic divisional structure, commanding all Army units – Regular and CMF – in New South Wales. It was also responsible for training some CMF units in other states.
