Access to Frecenet

We want to do some hiking around Frecenet penisula in Jan after we hike the overland. Does anyone know the availability of buses that might travel from Hobart to the peninsula? I have driven there in a hire car and remember the trip being around 1 to 1.5 hrs from memory?
I have read on a few websites that buses operate around the area but am unsure whether they are local or tourist busses and if they need to be booked.
