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.
