Not what it seems, this is actually A23-032 marked as A23-045. Transferred to the Air Force History & Heritage Branch (HH-AF) for refurbishment and eventual static display. It was repainted as an ARDU aircraft A23-045, relocated to SAAM and on display at SAAM in South Australia

Built as C-47B-35-DK 44-77128 and delivered to the RAAF in June 1945, A65-114 was immediately involved in the return of POWs from Singapore, later in Korea and as a VIP transport. In 1954 it was transferred to 38 Sqdn at Richmond and after 10 years joined the Aircraft Research and Development Unit at Laverton, moving on to Edinburgh when the ARDU relocated there. In October 1986 it was substantially damaged after a double engine failure on take-off and left gear collapse. Withdrawn for use with 13,897 hours recoded, it was transported to Port Adelaide for preservation in 1992

A8-132 was the eighth F-111 allocated to the RAAF and made its first flight in 1968, not delivered to RAAF at Amberley till July 1973 following storage in the US due to concerns about the type's serviceability. After operating with 1 Sqdn, from 1979 to 1988 it was allocated to ARDU at Edinburgh. The white lower surfaces were added to provide contrast in images of weapons release during trials. It later returned to testing as the prototype for the Avionics Update Program (AUP) and also engine replacement using surplus US stocks. In 2019 SAAM exchanged their preserved F-111 A8-134 for this one.

Of the 75 Hornets delivered to the RAAF, all but the first four were built in Australia at the Government Aircraft Factories (GAF) plant in Avalon, VIC. This one served 3 Sqdn from 1988 then ARDU before the fleet was retired in 2021

A3-115 was part of an order for six extra two-seat Mirages, built by GAF in Australia. Delivered in 1973, it was flown by 2 OCU and 77 Sqdn then ARDU until withdrawal in 1986. After 1999 it was displayed inside the gate at RAAF Edinburgh, one of the bases used by ARDU. Moved to SAAM in 2018

One of 68 PC-9s acquired by the RAAF, this is actually A23-032 painted to represent an ARDU aircraft. It originally flew with the CFS 'Roulettes' team and then moved on to FAC duties with various units in the toned-down grey livery.
