I Dunno if you're all aware but the Goodridges (of Jeep fame at Walcha) are having **their*** Auction on in Tamworth 4th November...which will be SIX Jeeps and 350+ lots of spares... It was in the LAND newspaper last week....or use MARATHON SPARE PARTS as a guide to googleing!
Also the Dubbo Auction is 11th of November and I expect that the reserves will be high if they exist... BUT to freight from Dubbo on a CMP is gonna cost you about $1500+ to Sydney! To the melbournites it would be $2.5k! try

for a full listing!
Add that to a sale in the boondocks and you need to be realistic about prices.
The Melbourne Museum Bellfield auction was location, location, and with a large shipping port it was great for o/seas buyers.
