Nepean Island (Norfolk Island)

Island Tiny uninhabited islet near Norfolk Island

Off Norfolk Island, Nepean is an uninhabited islet known for seabird colonies and basalt cliffs; access is restricted, so visitors usually view it from boat trips.

Nepean Island is a small uninhabited islet immediately off the southeastern coast of Norfolk Island in the South Pacific. It is notable for steep rocky cliffs and as a local seabird nesting site.

The islet offers no visitor facilities; views and wildlife-watching are normally done from boats rather than by landing. Landings are difficult because of steep cliffs and rough surf, so recreational visits are typically limited to coastal viewing and photography.

The island has remained largely uninhabited and is managed as part of the Norfolk Island environment; there are no permanent structures or services on the islet. It is kept largely in a natural state to protect seabird colonies and local vegetation.

Nepean Island sits a short distance offshore from the main island of Norfolk Island, near the historic Kingston area. The islet is part of the same external territory administered with Norfolk Island.

  • Wildlife: Important breeding site for seabirds; best observed from boats during the Southern Hemisphere spring and summer.
