Northern Command was one of several geographically based commands raised by the Royal Australian Air Force (RAAF) during World War II. Established in April 1944, it evolved from No. 9 Operational Group, which had been the RAAF's primary mobile formation in the South West Pacific theatre since September 1942, but had lately become a garrison force in New Guinea. Northern Command was headquartered initially at Milne Bay and then, from August 1944, in Madang. It conducted operations in New Guinea, New Britain, and Bougainville until the end of the war. Re-designated Northern Area in December 1945, it was headquartered in Port Moresby from March 1946 and disbanded in February 1947.
