Just offshore from Buca Bay, the small, hilly island of Kioa is home to four hundred Tuvaluans. Back in the 1940s the people of Vaitupu, the largest of the nine coral atolls in Tuvalu, were faced with a stark choice: cling on as rising sea levels began to erode their tiny island, or look for a new home. In 1947, the freehold island of Kioa, 1000km to the south in Fiji, was purchased by the people of Vaitupu for £3000. The first migrants arrived almost immediately and a steady trickle has continued ever since. The islanders live in the solitary village of Salia on the south coast. In 2005, they were formally granted Fijian citizenship. The fair-skinned Polynesian Tuvaluans have a lifestyle and language quite different from the Fijians. They are known as skilled fishermen and are often seen handline fishing from outrigger canoes way out to sea.
