Australian designed and built after both Britain and the US were unable to produce additional aircraft for other nations as a result of their need to produce for their own forces. With a decision made to use only those aircraft parts and engines already under manufacture in Australia, the resulting design had a stubby appearance. The first aircraft was provided to a training unit on 19 Oct 1942, and on 10 Apr 1943 the first squadron to be equipped with them (No. 83 Squadron) took delivery.

While there is no evidence of a Boomerang ever fulfilling its role of shooting down a Japanese aircraft, it proved to be a very effective light ground attack aircraft, working closely with troops fighting in New Guinea and the islands.
