Hi, I was able to track some down from a Hearns Hobby Shop in Flinders Street Melbourne. My wife had to go down yesterday on business so she purchased a couple of tins ($3.25 for 14ml), now all I have to do is get it matched by a local paint merchant.
To all who helped and responded to my request,
Thankyou for taking the time.

Cheers and Happy Land Rovering,
Mick.
