Most Aussies we met think we are crazy but half our 2 month stay was a 32 day road trip from Adelaide to Cairns - 5600 kilometers! So we stayed a few days in Noosa too, and some other spots for a day or two as we worked our way north. Rested a few days in Cairns before flying to NZ. We like driving because we see more and meet more people. Had a great time! And for comparison, we've driven a couple of times from our home in Canada to friends' vacation place in Florida, 3 days down, 3 days back, also 5600 kilometers round-trip - so better to take 32 days to do that distance and see your wonderful country!
