In reply to davis:
Was out there last November but wasn't climbing just touring so can steer on the free camping. We hired a small motorhome and only paid for camping at Coles bay, which wasn't much. Around that area and the Totem Pole you would have to pay as it was all parkland but around the rest of the island you could certainly motorhome it for free.
We did walk down to the Totem Pole: you need a seperate, long, ab rope and I'd want better than prussiks for getting back up, it is difficult to see beyond that but the partial view I got looked awesome.
We went there as part of a longer trip and not sure what your circumstances are but we decided to hire a motorhome rather than hire a car and camp as the flexibility was much better, it was more comfortable and we wouldn't have to use excess baggage to bring the camping equipment over.
Whilst not climbing in Tasmania we did go to Arapiles on the mainland which is the Mecca over there and the weather is a lot better too!
