Airborne forces raised by Australia have included a number of conventional and special forces units. During the Second World War the Australian Army formed the 1st Parachute Battalion; however, it did not see action. In the post-war period Australia's parachute capability was primarily maintained by special forces units. In the early 1980s a parachute infantry capability was revived which led to the Parachute Battalion Group forming in 1983 based on the 3rd Battalion, Royal Australian Regiment. In 1997, a full time commando regiment was raised that was able to conduct large-scale operations which matured during the 2000s. In 2011, 3 RAR relinquished the parachute role with the Army deciding to opt out of a conventional parachute capability in preference to a special forces large-scale parachute capability.
