The Carteret group, also known as Tulun, is located 100 kilometres northeast of Buka Township. The group comprises of six small islands surrounding a lagoon. These islands are only 1–2 meters above sea level with a total land area of 80 hectares. They have mainly sandy soils and produce coco nuts and other tree crops. The islands were once inhabited by Polynesian people but were displaced by the Buka people some 300 to 400 years ago.
