Indispensable Reefs

The Indispensable Reefs (English indispensable reefs ) are a chain of three in the northeast of the Coral Sea ( a marginal sea of the Pacific Ocean ) lying atolls, about 72 kilometers south of the island of Rennell, in which the Salomonensee begins. They belong to the group of Rennell Islands and thus also to the province of Rennell and Bellona Island State of Solomon Islands.

The associated atolls Indispensable Reef North, Reef Indispensable Indispensable Middle and South Reef are both uninhabited. They extend from northwest to southeast about 104 km air line and are up to 18 km wide.

Little Nottingham Islet in the Middle Reef is the southernmost island of the Solomon Islands.
