if you are going to Gold Coast, then getting a car is better. Otherwise you may have issues getting food (or you got too bored staying in the hotel)
Melbourne - more considerations.
If you are:
1) Staying in Melbourne CBD
2) Wishing to join local tours
then - I wouldnt recommend - find car park is a problem. and joining local tour will bring you to places where public transport wont reach,
If you are staying a bit out (motel rather than business hotel).. or prefer to travel at your own time. (if you wake up late and like to go for supper or night tours). Then would be good to rent a car. Melbourne has a very friendly road system.
Avis, Trifty, Europa car are offer similar prices. Usually it pays to ring them or check their website for their promotion package. Make sure you get those that offer unlimited KM, or tell the car rental people where you intend to go. If you have driven more than the allowed milage, you will pay through your nose.
If you are under 24, car rental will be more expensive and you cant drive cars over 3.0L
note: a word of caution. If you scretched the car, dirty the cushion (if you travel with children) of the seat, return the car with less than full tank of petrol, the rental company has the right to charge you the extra. So be extra careful.
