I too believe there is a big future in food tourism and wilderness tourism for Tassie. I personally love the place (except Queenstown) but you have to go through Q to get to Strachan from Hobart. Even Roseberry in the pouring rain and at 4 degrees C is gorgeous in its own quaint way. I hear the western mines at Zeehan and Roseberry will be expanding shortly.
But the rest of the place is God's Own Untouched Beauty, as far removed from the awfulness of Sydney as one can get, south of Uluru.
On the other hand Tassie is still very non-mainstream. As such it will not attract the same tourism and development $$$ as Surfers or Noosa (Thank God). For those of us who are somewhat different from your average yahooing Australians, I don't mind if we keep it that way, really. Says someone who can drive to Surfers in an hour and can be frolicking with the koalas in the Noosa National Park within two hours of leaving home.
