The south island in new zealand is breathtakingly beautiful. But there's too many earthquakes. I wouldn't live in NZ, would rather live in Zurich Switzerland....same beauty, great lifestyle and no earthquakes in Zurich.
12% of Kiwis live in OZ, wonder why?
NZ is beautiful, South Island Queenstown region in particular, but only to visit, I would not live there.
In regards to OZ, I lived in Melbourne a couple years in 90', but prefer QLD. Not North part though, south up to Noosa. Gold Coast is the best IMO, great beaches and big enough to have everything you need in one place.
