Melbourne / Tasmania / Wellington, NZ lifestyle ?

This is not exactly a property investment post,
more of a property lifestyle dilemma question.

I am an early 40s married Australian, born in Melbourne.

I own a flat in bay side Melbourne.
It is nice living there, but it is noisy.
The hedonistic lifestyle that has taken
over the area I am living in last 10 years,
has become annoying. Or maybe I am just getting old…

I would love to buy a 600m2 lot house in Melbourne suburbs,
but the high prices in my opinion are not justified.

I am currently living and working in Wellington, New Zealand.
Compared to Melbourne I LOVE the peace and quiet in Wellington.

I considered buying a property in Wellington, NZ,
but potential earthquakes wiping out a NZD$500K investment
and the fact that it is far from family and friends in
Melbourne is a turn off. The economy is not that strong in NZ,
so the houses seem a little overpriced.

So I have been considering Northern Tasmania.
Houses prices are more reasonable. I could get
an 0.5 hectare block with a 1900s fixer upper federation
weather board on it for AUD$350K. I wouldn't be
working in Tasmania, just house DIY and taking it easy on the lot.
I suspect I'll find the peace and quiet I have in
Wellington in Tasmania. If I got bored in Tasmania I
could take a ferry back to Melbourne and live in Bayside,
Melbourne until I got sick of the madding crowds again.

Though I have heard a few stories from Victorians
who made the switch to Tasmania, and although they
praise the state, they end up chucking it in and
returning to Melbourne after a few years…

What should I do ?
What other information should I consider ?
High quality problems, I know…

Regardless, would appreciate advice/opinions from anyone
who has made the switch from Melbourne to Tasmania North.

Appreciated,
M.
