Nukumanu Islands, Remote atoll in Autonomous Region of Bougainville, Papua New Guinea.

Nukumanu Islands comprise more than twenty coral islets arranged in a ring formation surrounding a central lagoon in the Pacific Ocean. The formation creates a protected marine environment with shallow waters and reef structures that support local life.

The islands first came under German control before transitioning to Australian administration in 1914. By 1920, they became a League of Nations mandate territory under Australian oversight.

Residents depend on traditional fishing methods, gathering sea cucumbers and harvesting trochus shells for trade with Asian buyers. These practices shape daily life and the community's economic activities.

Reaching the atoll requires specialized transportation since it sits far from major populated areas and has limited regular connections. Visitors should prepare for extended travel times and basic conditions once there.

The border between Papua New Guinea and Solomon Islands runs between Nukumanu and Ontong Java Atoll, not through Nukumanu itself. The nearest land is Ontong Java, 38 km south; the closest point of PNG proper, New Ireland, lies 682 km west.
