Ned and I are based in Bunbury Western Australia. From Bunbury to Australian Auctions Arms in Doncaster East, Melbourne Victoria, it is a 3,387km drive. This equates to 2,104 Pommy miles. (which were also Aussie miles up to 1971).
So a quick round trip with a short diversion to the Lithgow Museum in New South Wales equates to a total distance of 7,965km.
For your interest I have attached a Google map of the route.
Austrlia is a very big country.
Peter perhaps you need a new map.
Of course this is based upon having enough cash to win the auction, with enough left over to fund the necessary beers for the road trip.
Cheers
Paul
