Hello Tony,
Welcome to the ex-military Land Rover fraternity of Australia!
Here are two forums that might be of interest to you ...
The Registry of Ex Military Land Rovers
http://remlr.com/forum/index.php ... There is a devoted Perentie section there.
Or perhaps AULRO Australian Land Rover Owners
http://www.aulro.com
I have some Series III Land Rovers.
Oh and a 1940 Australian Built by Holdens Chevrolet MCP truck
Kind Regards
Lionel
