No. 9 Operational Group was a major Royal Australian Air Force (RAAF) formation providing fighter, ground-attack and anti-shipping support to the Allies in the South West Pacific theatre during World War II. Established in September 1942, it acted as a mobile striking force independent of the RAAF's static area commands. As the war in the Pacific progressed, No. 9 Operational Group itself developed into an area command called Northern Command, responsible for garrisoning New Guinea.
