In the South Pacific there is no such thing as a deserted island. They may be the most isolated in the world but every one of the region‘s 20,000 islands has been colonised - from New Guinea, home to birds of paradise and the tribe whose brutal initiation ceremony turns young warriors into ‘crocodile‘ men, to Fiji, French Polynesia and Hawaii.

These journeys were no mean feat. It has been estimated that an average of one species every 60,000 years makes it to Hawaii. Incredibly, many of these colonisers made it to these islands on the back of the most violent forces of nature, like cyclones and tsunamis.
