Manus Island

Manus Island is the largest island in the Admiralty Islands archipelago and is the administrative centre of Manus Province in northern Papua New Guinea. The island’s main town and port is Lorengau.

The island and surrounding isles played a strategic role during the Pacific campaign of World War II and contain military sites and wartime remains. Manus is also a centre for local fisheries, small‑scale agriculture and inter‑island transport within the archipelago.

In the postwar period the island has hosted a range of naval and support facilities on adjacent isles, and it remains the primary population and service hub for Manus Province. Marine and coastal environments around the island support diving and reef activities.

Manus lies north of the New Guinea mainland in the Bismarck Sea and is part of Papua New Guinea’s island province system.
