There are some islands located at a distance between 50 m and 2 km from the main island, but still within the fringing reef: Solnohu (south), Solkope (southeast), 'Afgaha (far southeast), Husia (close southeast), as well as Hạuameamea and Hạua (close together northeast). Additionally, there is a separate chain of islands between three and six km northwest and west of the westernmost point of Rotuma Island. From northeast to southwest, those are Uea, Hafhai with nearby Hofhahoi, Hafhaveiaglolo, Hatana and Hạf’liua.
The islands have an aggregate area of 44 km², of which the main island Rotuma occupies 43 km². Only the main island is permanently inhabited.
The Rotuma Group comprises a Dependency of Fiji. The population of the dependency at the 1996 census was 2810.
