Off the north west coast of Sabah, lie a group of islands including Pulau Balambangan, Pulau Banggi, Pulau Jambongan, Pulau Balak and Pulau Malawali. A number of wrecks and rarely dived reefs have recently been discovered in this area. Three wrecks have been discovered to date, all thought to be merchant ships.
Two are lying at 20 - 25m and the other lying a little deeper at 50m. All three wrecks resemble coral gardens being completely covered in colourful sponge and soft corals.
Marine life around the wrecks includes schools of glassfish, lion fish, scorpion fish and huge resident grouper. The surrounding islands have shallow fringing reefs with all the regular reef fish such as the coral trout, butterfly fish, angel fish and the occasional cuttlefish. These reefs have rarely been dived and therefore new sites are being discovered on many of the trips.
