If you had all the time in the world then I’d say just pack up your things, hop in a camper and travel around Australia. The whole country, aside from the centre of some of the cities maybe, is really well suited to campervan travel. There are plenty of caravan parks available offering powered sites or some really beautiful national park (usually a small overnight fee) and free camping spots for those happy without power some nights.  If you plan for it, it is actually fine and offers you some really gorgeous locations that would not have been possible otherwise.   If you are going for the free camping option you should be travelling in a completely self contained van by the way. Do it right people, do it right.
