Buka Island at a Glance

About Buka Island

Buka Island lies in the Autonomous Region of Bougainville in Papua New Guinea and forms the northern margin of the Bougainville group. The island is notable as the location of the regional administrative centre and as a maritime gateway to Bougainville Island.

Beaches, karst limestone terrain and coral reefs fringe much of the coast, while settlements and the main wharf are concentrated around the southern tip. Local transport relies on boats across the Buka Passage and on a small regional airport serving inter-island flights.

During the 20th century the island was a focus of colonial administration and later regional governance; it remains the seat for the Autonomous Bougainville Government and local services. Infrastructure and services are modest compared with larger Papua New Guinea centres.

Buka Island sits immediately north of Bougainville Island, separated by the Buka Passage, and lies in the western Pacific near the Solomon Islands arc. The island’s southern settlements face Bougainville across a narrow tidal channel.

  • Administrative centre and transport hub: The island hosts the region’s administrative functions and the main local wharf, making it the usual arrival point for visitors to Bougainville.

What to See#

  • Buka town: Buka town at the island’s southern tip, which contains the main wharf and the administrative centre of the Autonomous Region of Bougainville.
  • Buka Passage: A narrow, tidal channel separating the island from the larger Bougainville Island; it is the main navigation route used by local boats and ferries.
