I thought most were taken to airfields like Oakey and Tocumwal as mentioned above.
500N,
With due respect, not quite.
5AD Wagga received nearly all the UK-built and about half the DAP-built Beaufighter survivors.
1AD Laverton received the other half of the Mk.21's.
Both 6AD Oakey and 7AD Tocumwal received a mere handful only.
There seems to have been an AD/type relationship; 6AD at Oakey seems to have been the final resting place for virtually all of the Spitfire and Kittyhawk survivors.
Cheers.
