The Indispensable Reefs ( English indispensable reefs ) are a chain of three atolls in the northeast of the Coral Sea (a marginal sea of the Pacific Ocean ) , about 72 kilometers south of Rennell Island , where the Solomon Sea begins. They belong to the province of Rennell and Bellona of the island state of Solomon Islands .
The associated atolls Indispensable Reef North, Indispensable Reef Middle and Indispensable Reef South are each uninhabited. They extend from northwest to southeast over 104 km as the crow flies and are up to 18 km wide.
Little Nottingham Islet in the Middle Reef is the southernmost island in the Solomon Islands.
