Steve, there is SFA up there apart from a couple or roads and sand I am more with Luke, down south would be good. Nice winding roads through the forests, heaps of places to stay and stop over etc and lots of good places to grab a feed. Caves Rd is a bloody good drive .........as long as you don't get stuck behind a convoy of tourists in Corollas and Toragos doing 40 below the limit I would be keen and I guess people would need a bit of notice to etc and time to book accommodation, but defiantly something I would be interested in. Only downside is the chance of blowing something up 300km+ from home
