That's what a road trip around Australia is called, "The Big Lap," and more and more people are doing it. I've not done the "lap" in one single trip, that would take 12-18 months were I to spend the right sort of time to see the good stuff - I'm not into rushing it - and places are different across the seasons so one almost has to go back to each place (some of them) twice or more, I've seen much of the country on many trips though. I'm planning my big lap although it'll not be a one way lap, I'll go this way and that depending on the season and the commitments I have back home and elsewhere although when I do the big lap I'll no longer be working so I should be able to stay away for extended periods of time so with no really timeframe issues it's sure to be pretty awesome.
