After World War II, the division remained off the Australian Army's order of battle until the 1960s, when it was reformed in New South Wales. In 1965 it adopted a certification role, determining the operational readiness of units deploying to Vietnam. It was re-formed in 1973 as a full division based in Queensland and in the decades that followed it formed the Australian Army's main formation, including both Regular and Reserve personnel. Throughout this period, the division's component units undertook multiple operations, mainly focused on peacekeeping in Africa, Asia and the Middle East.
