Rotorlift based at the Hobart airport offer tourism flights, the other operators in that area focus on utility work. There used to be a small tourist operator on the West Coast at Strahan but I don't know if they're still there. Launceston area has a few operators mainly focussed on Ag & utility. Par Avion operate fixed wing tours & Tasmanian Sea Planes operate a float equipped Beaver out of Hobart & offer flights around the main attractions in that area, might be cheaper & who doesn't love the sound of an old radial passing overhead.
