I bought a car as I planned to stay longer. It's certainly cheaper than a rental and quite common in Australia. There are several places specialized on used car sales for tourists but watch out for so-called bargains or good deals that a salesman wants to talk you into. Most of the times it's an old beat-up wreck that was previously owned by another traveler and left behind for its poor condition. Make sure it's registered and insured, otherwise you have to do that yourself which is not only time consuming but also difficult without permanent address in Australia. Eventually a hotel address will do.
