I first heard this story when I was an air cadet in Oz and we were flying from Oakey and Amberley. As I remember it, there were a pile of late mark Spits (numbers varied between 12 and 24) were delivered to Oakey at the close of the war -- I can't remember which mark, but I think that they were Griffon engined -- and the war ended after they arrived but before they were uncrated and flown.
The story runs that they were stuck out in a cave in the bondu rather than being scrapped, and that people had gone to look for them, but that no-one had ever found anything. Best of luck to all of those involved!
