Phillip Island VIC.
I visited here to see what became of two Caribous that I flew in the RAAF. One is displayed outdoors along with a Grumman Tracker (Vietnam connection? No idea.) The other has been broken up for spare parts with the cockpit being retained as a possible flight simulator.
There is also a UH1-H Iroquois , a Huey Cobra as well as a Canberra bomber in long term restoration. Many other interesting military displays as well. They recently received a $5 million government grant to build a new and larger facility so hopefully the aircraft will end up indoors.
