The pre-existing Kingaroy civil aerodrome was taken over by the Royal Australian Air Force (RAAF) in late 1941. The first 96 buildings were erected by 10 July 1942, and No. 3 Initial Training School (ITS) moved to Kingaroy later that year. The wartime entrance was from Buttsworth Road east of the aerodrome, but today the main entrance is from the west via Warren Truss Drive, about 1km south of Kingaroy on the Kingaroy-Cooyar Road.

The surviving RAAF structures include a Bellman hangar. To the northwest of the hangar, north of Geoff Raph Drive, is an inflammable store/morgue with a roof ventilator, vehicle wash bay slab, skillion roofed crash ambulance station, and a skillion roofed motor pool; a small fibro radio telegraph shack also stands to the north of Geoff Raph Drive, to the east of the motor pool. Southwest of the hangar is a flat-roofed meteorological hut (relocated) and a gable roofed locker room; southeast of the hangar is a roofless concrete machine gun test butt building. A gable roofed hospital building, ambulance garage and prophylactic room/isolation ward are located further east, just south of Geoff Raph Drive.

A memorial to 24 RAAF and AIF personnel who lost their lives in accidents in the Burnett during the war is located near the intersection of Warren Truss Drive and Geoff Raph Drive.
