By mid-1943, nearly all frontline use of the Wirraway had come to an end, having been replaced by the newer Boomerang, itself a fighter-orientated derivative of the Wirraway. The majority of front-line squadrons of the RAAF had at least one Wirraway attached to serve as a squadron 'hack', that is, an aircraft employed on errands such as visits to headquarters or other bases. At least one aircraft (formerly A20-527) flew as part of Headquarters Flight 5th Air Force in full United States Army Air Forces markings.
