For much of the history of the Semporna region on the south-eastern part of Sabah, this region consists of a sleepy town and a few villages with the main occupation being fishermen. This is not the case any more, since the last two decades this region has become the underwater paradise for the state. To protect the marine diversity of this region, Tun Sakaran Marine Park was established in 2004 and managed by the Sabah Parks. This Marine Park has eight islands as well as three large reefs and the park is surrounded by the Celebes Sea. Because of its proximity to the world’s reknown Sipadan Island Park, divers, snorkellers and tourists are also taking time to visit this park. If one comes from the Semporna Jetty, this would take about 30 to 45 minutes and covering a distance of 15 to 25 kilometres, depending of which island is the destination.
Sibuan island belongs to a grouping of eight islands that formed the Tun Sakaran Marine Park, and some people reckoned that Sibuan Island as the most beauitful island in the Celebes Sea.Semporna region is fast becoming the paradise playground for the divers and snorkellers who come here for the crystal clear sea water and the mutlitude of marine life. With increase frequent flights from Malaysia Airlines and budget airline Air Asia to the Tawau airport, getting to the islands of Semporan are not so difficult these days. Apart from the immensely desired Sipadan island, this region offers plenty of other islands for the adventurous snorkellers to explore and Sibuan island is one of them. Located on the south west corner of a reef, Sibuan island belongs to a grouping of eight islands that formed the Tun Sakaran Marine Park. This marine park was gazetted in July, 2004 to give greater protection for its environment and its eco-system.
