One of the 4th Armoured Brigade's regimental groups supported Australian Army offensive operations in New Guinea and Bougainville during 1944 and 1945. The 2/4th Armoured Regiment was transferred to New Guinea in August 1944, and came under the command of the First Australian Army. From January 1945 until the end of the war, C Squadron of the 2/4th Armoured Regiment supported the 6th Division during the Aitape–Wewak campaign. The regimental headquarters and two other squadrons took part in the Bougainville Campaign from October 1944 until the end of the war as part of II Corps.
