North-Western Area Command was one of several geographically based commands raised by the Royal Australian Air Force (RAAF) during World War II. Its wartime sphere of operations included the Northern Territory, adjacent portions of Queensland and Western Australia, and the Dutch East Indies. The command was formed in January 1942, following the outbreak of the Pacific War, from the western part of Northern Area Command, which had covered all of northern Australia and Papua. Headquartered at Darwin, North-Western Area Command was initially responsible for air defence, aerial reconnaissance and protection of the sea lanes within its boundaries.
