I’ve lived in Tasmania most of my life, I will try my best to
answer your questions.
Land price varies a lot depending on the type of land, how big it is, and the location. How many acres do you need? And what kind of homestead are you thinking of having there? Pasture? Forest? Many acres? or 1/4 acre?
Land at the moment is really overpriced, in a bubble that is going to burst at some point, it’s hard to say when this will happen though.
I like the climate here, some people find it too wet though. Different parts of the island have different climates, east coast is more similar to the mainland and is a bit warmer and drier, west coast is very wet and doesn’t have much farming, other parts of the island, some are similar to Northern California, some to Southern England, generally there is more rain in winter and spring and less in summer.
Rainfall varies a lot - some parts of the midlands might have around 300mm rain a year, many other places have around 1000mm- 1200mm.
There is the La Nina/El Niño cycles here where some years are wetter (or drier) than others - dry years we might have summers with 6 week without any rain at all, so that is something to keep in mind.
Downsides… wildlife can be difficult - they will eat everything unless it’s fenced appropriately, or have dogs, or can cull them at night (or have neighbours culling). Bushfires happen, so property needs to be selected and designed carefully.
There are venomous animals here - all Tasmanian snakes are venomous (but usually not aggressive, just a matter of being careful where you tread), we are home to the world’s most venomous ant, and a bunch of other biting insects, but snakes are the only real danger.
Tasmania has a lot of retirees and the sick care system is pretty strained - there are long wait times in the hospitals.
maps.thelist.tas.gov.au is a really good site to look at if you’ve found a block of land (or an area) you might like, you can put in a bunch of map overlays such as nearby transmission lines, 10m contours, farming suitability for various crops (which will tell you the pH, soil depth and other information about the land), I used this tool a lot when we were looking for land.
