Our take

Last Polynesian kingdom: deeply traditional, a rugby nation, remote and peaceful. The case for living here is clean air.

About Tonga

Tonga is a Polynesian kingdom in the South Pacific, the only country in the Pacific never to have lost its sovereignty to a colonial power, and it wears this independence in its traditional culture, its chiefly system, and the deep community values that shape daily life on its islands. The islands are surrounded by some of the finest humpback whale watching waters in the world. Those who love ocean culture and traditional Polynesian life will find it quietly extraordinary.
