Manra Island, formerly known as Sydney Island, is a nearly circular atoll in the Phoenix Islands archipelago of Kiribati. A defining feature of the atoll is its central lagoon, which is completely landlocked and possesses no outlet to the sea, making its waters hypersaline, roughly twice as salty as the surrounding ocean. The island is currently uninhabited following failed resettlement attempts by British colonial authorities in the 1930s, which were abandoned due to severe drought and lack of fresh water. Despite this, ancient Polynesian ruins, including stone platforms and maraes, suggest a much earlier period of human habitation. Manra is a significant sanctuary for wildlife, particularly as a major breeding ground for seabirds such as the wedge-tailed shearwater and various species of boobies. As part of the Phoenix Islands Protected Area (PIPA), the atoll is under strict conservation management to preserve its pristine terrestrial and marine ecosystems.
