DH and I have decided to save our pennies and go for a 5 week road trip from Perth to Brisbane this time next year!

We need to trade in our car next year, so we're looking at a couple of different options - either buying another sedan, which is what we have now, or buying a 4WD for travel purposes. I'm not sure about the Perth-Brisbane trip though, is there a need for a 4WD?

Anyway, I'm looking for tips from anyone, places I can't miss, etc. Please help!

The best part is - DH says that we can do a few BB meetups along the way!!!
