That's right NavyG. Proper explanation (from Wiki) below, but in simple terms, the big island that we all think is Papua New Guinea, is actually split down the middle. The right hand half is Papua New Guinea, with the left hand half being Indonesian owned/territory. West Papua (where WWI now are) is on the very left tip of the Indonesian part.



West Papua (Indonesian: Papua Barat) is a province of Indonesia covering the western peninsula of the island of New Guinea. It is the least-populous province of Indonesia and one of two situated in Indonesian New Guinea, with the province of Papua also lying to the east. Prior to 2007, the province was known as West Irian Jaya (Indonesian: Irian Jaya Barat). The region covers the Bird's Head (Doberai) and Bomberai peninsulas and the surrounding islands of Raja Ampat. Its first census, in 2010 recorded some 761,000 people.
