Operational Training Units first received the CA-12s in October 1942.
Five Royal Australian Air Force (RAAF) squadrons were equipped with the Boomerang.
The first squadron to become operational with Boomerangs was on April 4, 1943.
On May 16, 1943, three Mitsubishi G4Ms were intercepted by two Boomerangs. No planes were shot down.
Once Britain and the United States was able to supply fighters for the Royal Australian Air Force the Boomerang was relegated to support.
The Boomerang's maneuverability and armament made it an ideal close support aircraft. It was able to show excellent service in New Guinea and Bougainville.
