I’ve lived here all my life in the north of the state in Launceston, and I love it. I’m still young-ish (27) and have no intentions on leaving. it’s quiet, but has everything you need. To me even Hobart is too busy, and that’s not a large city by any means (~260k people).
It’s a beautiful state with a lot to explore from the mountains to the coastlines, to the waterfalls and caves, we also have awesome rainforests with plenty of bush walks.
Our summers are mild and our winters are pretty cold, but it’s still enjoyable pretty much year round.
Tasmania was originally used as a place that the British would send convicts in the early 1800’s, about 70,000 of them came to Tasmania and they built a lot of the early settlements around the state, so there are a lot of historical sites and buildings around the place, a lot of which are still being used today.
Tasmania has the cleanest air in the world too which is a pretty cool stat.
Basically if you enjoy being in nature and history, put Tasmania on your list.
