Cenderawasih Bay in the context of Papua province

The Biak Islands (Indonesian: Kepulauan Biak, also Schouten Islands or Geelvink Islands) are an island group of Papua province, eastern Indonesia in the Cenderawasih Bay (or Geelvink Bay) 50 km off the north-western coast of the island of New Guinea. The group consists of the main islands of Biak, Supiori and Numfor, and numerous smaller islands, mostly covered in rain forest. The population of the archipelago is about 130,000.

Papua, formerly known as West Irian and Irian Jaya, is a province of Indonesia, comprising the northern coast of Western New Guinea together with island groups in Cenderawasih Bay to the west. It roughly follows the borders of the Papuan customary region of Mamta – Tabi Saireri and is divided into eight regencies (kabupaten) and one city (kota), the latter being the provincial capital of Jayapura.

It is bordered by the nation of Papua New Guinea to the east, the Pacific Ocean to the north, Cenderawasih Bay to the west, and the provinces of Central Papua and Highland Papua to the south. The province also shares maritime boundaries with Palau in the Pacific. Papua, along with the five other Papuan provinces, has a higher degree of autonomy compared to other Indonesian provinces.

West Papua (Indonesian: Papua Barat), formerly Irian Jaya Barat (West Irian), is an Indonesian province located in Indonesia Papua. It covers most of the two western peninsulas of the island of New Guinea: the eastern half of the Bird's Head Peninsula (or Doberai Peninsula) and the whole of the Bomberai Peninsula, along with nearby smaller islands. The province is bordered to the north by the Pacific Ocean; to the west by Southwest Papua Province, the Halmahera Sea and the Ceram Sea; to the south by the Banda Sea; and to the east by the province of Central Papua and the Cenderawasih Bay. Manokwari is the province's capital and largest city. With an estimated population of 578,700 in mid-2024 (comprising 304,140 males and 274,560 females), West Papua is the second-least-populous province in Indonesia after South Papua, following the separation off in December 2022 of the western half of the Bird's Head Peninsula to create the new province of Southwest Papua, containing 52% of what had been West Papua's population. Its population density is similar to that of Russia.

After the Japanese surrender in 1945, the Dutch remained in New Guinea until 1962 when they transferred the control of the region to the Indonesian government as a part of the New York Agreement. West Papua was legally created as a province in 1999 (out of the original Papua Province), but it was not inaugurated until 2003. Consisting until 2022 of twelve regencies and one city, the province has a special autonomous status as granted by Indonesian legislation.

Biak is the main island of Biak Archipelago located in Cenderawasih Bay near the northern coast of Papua, an Indonesian province, and is just northwest of New Guinea. Biak has many atolls, reefs, and corals.

The largest population centre is at Kota Biak (Biak City) on the south coast. The rest of the island is thinly populated with small villages.

Supiori is an island of the Schouten Islands archipelago in Cenderawasih Bay, just west of Biak island in Papua Province, Western New Guinea, northeastern Indonesia.
