Planning to drive from Brisbane to Perth this coming January. I want to see the country and get about three weeks in WA windsurfing. I'll be driving my 2003 Hiace. It's as tough as they come, and in good nick, but I need some suggestions on what kind of vehicle preparation I should do, what sort of spares and supplies are commonly carried on such journeys, and what dangers to avoid. I know some on this forum are old hands at this sort of thing so any input is very welcome.
