For something further afield and a little closer to the Cold War timeline...
Back in 1997, Australia took charge of the cargo from an An-124 aircraft carrying equipment bound for Bouganville to support Sandline supplied mercenary forces who were going to be operating in the area.
Included in the haul were two fully operational Mi-24 helicopters (of at least D model or better from what I understand)
The two helos were (and still were as of 2014) being stored at RAAF base Tindal in the Northern Territory, from the report, they were to be disposed of in 2015
