There used to be a Mooney parked on the side of the road in a paddock in the southern suburbs of Perth. Don't know if that is still there, always wondered about it's history! It was painted bright yellow
On Armadale Rd....... Yep still there.
Use to be an old DC3 as a kids play ground at a Maccas in Midland, but that went a few years ago. I believe it ended up in a mini series or similar on the ABC. Static only though.
There is a Cherokee 6 (I think) on the Dive Trail in about 7 mtetres of water down at Rockingham.
