Arthur,
Glad to here your going to do some more research.
Here is an ad for Regent Motors from the Weekly Times and their stand at 1949 Melbourne Royal Show in September 1949.

For Land Rovers at a major Australian agricultural show we can't get much earlier than this. The Sept 48 Melbourne Royal Show was that touch too early for the Land Rover to appear.
We know from a photo in the Melbourne Argus in November 1948 that Regent Motors had received a Land Rover. This is consistent with R860004 appearing in WA and the early vehicles arriving at Grenville Motors in December 1948.
The June 48 owners manual lists Regent Motors as a major supplier.
Also the Regent Motors Dealer list which has Donald Gorringe and Autocars of Launceston at the bottom of another one of their ads from the Weekly Times in early 1953

I hope you find some more early vehicles
