response to a request by Sir Thomas Blamey for an army cooperation squadron operating a relatively slow aircraft, No. 4 Squadron, equipped with the Wirraway, was dispatched to Port Moresby during early November 1942. Operating over New Guinea, the type performed aerial reconnaissance, photography, artillery spotting, communication, supply drops, dive-bombing, ground attack and propaganda drops. In this capacity, the Wirraway proved to be fairly suitable; however, due to the risk of being misidentified as a hostile Zero, altitude restrictions were often imposed to deter incidents of friendly fire from Allied anti-aircraft gunners. Having become known for its versatility, fighter versions of the Wirraway operated over New Guinea for some time on ground attack and other Army co-operation tasks until other RAAF aircraft such as the Boomerang and American Curtiss P-40s were made available in sufficient quantity to replace them. By mid-1943, nearly all frontline use of the Wirraway had come to an end, having been replaced by the newer Boomerang, itself a fighter-orientated derivative of the Wirraway.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. Post-war and civil service Post-war the Wirraway continued in RAAF service as a trainer at Uranquinty and Point Cook and was taken on strength by the newly formed RAN Fleet Air Arm in 1948. Wirraways also served with the squadrons of the Citizen Air Force (a flying reserve force of the RAAF established in 1948) alongside CAC Mustangs, partially equipping No. 22 (City of Sydney), No. 23 (City of Brisbane), No. 24 (City of Adelaide) and No. 25 (City of Perth) Squadrons. Duties were not limited to training flights: a Wirraway patrolling for sharks crashed on a beach at Maroochydore on 30 December 1950, killing three children and injuring 14 other people. One Wirraway (A120-145) was lost during naval service on 18 June 1953 following an engine failure after taking off at Nowra; the pilot survived. The RAN retired its Wirraways in 1957, replacing them with de Havilland Vampires. After CAC Winjeels started to enter service, the RAAF commenced phasing out its Wirraways on 4 December 1958 with a farewell flypast held at Point Cook
