To narrow things down further I really liked the area around Brisbane in Queensland. For me one of those big detached places looking out to sea at Hervey Bay would be fine.
There is a downside here though...Australia is such a long way from anywhere else. I could only relocate to the other side of the world if able to do it 35 years ago. At that time my family was young enough to adapt to the change and they would all have grown up in Australia. To up sticks now would just be too much of a problem. Leaving behind family, especially the two new grand children who arrived in 2012, would now make a life in Australia unworkable. For that reason I would have to choose somewhere closer to home.

For me it's Croatia. At the risk of sounding like a Croatian tourist board advert, good standard of living, beautiful coastal areas and islands, plenty of wildlife and not too far from home.
