The '''First Australian Army'''  was a [[field army]] of the [[Australian Army]], during [[World War II]]. The formation's headquarters was raised in April 1942 from the existing [[1 Aust Corps|1st Australian Corps]] headquarters, assuming command of all Allied troops in [[Queensland]]. Initially, the formation was assigned a defensive role in anticipation of a possible Japanese invasion; however, this threat subsided and eventually the army was deployed to [[Lae]], in [[New Guinea]], in late 1944, where it co-ordinated Australian offensives around [[Aitape-Wewak campaign|Aitape]], in New Guinea, on [[New Britain campaign|New Britain]] and [[Bougainville campaign|Bougainville]], and around [[Battle of Madang|Madang]]. The formation was disbanded in February 1946, when it was redesignated as the [[8th Military District (Australia)|8th Military District]].
