Climbing in Tasmania

I am going to Tasmania in Feb and looking for some low commitment Trad climbing in Freycinet / Coles Bay.

My questions are:

- Is the whitewater wall camp site accessible in a 2wd rental car?

- how are the approaches to the crag. Is bringing a single 70m rope sufficient and are there easy rappels down to the crag or is it just walk in access.

- are there a lot of climbers in Feb at the campground on weekends or weekdays we can ask for beta?

Thanks
