Papua New Guinea, is a country in Oceania, occupying the eastern half of the island of New Guinea and numerous offshore islands (the western portion of the island is a part of the Indonesian provinces of Papua and West Papua). It is located in the southwestern Pacific Ocean, in a region defined since the early 19th century as Melanesia. The capital is Port Moresby.
Papua New Guinea is divided into four regions, that are not the primary administrative divisions but are quite significant in many aspects of government, commercial, sporting and other activities.
The nation has 20 province-level divisions: eighteen provinces, the Autonomous Region of Bougainville and the National Capital District. Each province is divided into one or more districts, which in turn are divided into one or more Local Level Government areas.
Provinces are the primary administrative divisions of the country. Provincial governments are branches of the national government – Papua New Guinea is not a federation of provinces.
