family camping on Bruny Island

I'll be visiting Tassie with my family and we'd like to do some family camping on Bruny Island. Any recommendations?
We're also looking for another location to camp for 3-4 days later in our trip. We've got small kids so somewhere near or at the car is preferable.
I'm still trying to get an overnight hike in with my 5yo while visiting. I was thinking a place were it's not too far to a hut would be nice, but am happy to use a tent. Any suggestions for a good relatively easy walk suitable for him?
