There are 19 aircraft on display, as well as 38 major displays, relics of crashed aircraft, and 21 engines. The exhibitions are being continually updated by a small group of enthusiastic volunteers of the Aviation Heritage Society of the Northern Territory, a non-profit association. Aircraft include a B-25 Mitchell Bomber – one of the few surviving in the world with a proven track record. There are Mirage and Sabre jet fighters, and a Royal Australian Navy Wessex helicopter that assisted in the clean-up of Darwin after Cyclone Tracy struck on Christmas Day 1974. The latest acquisition is an F-111C which arrived by road from Amberley on 16 June 2013.
