Pulu Keeling National Park is one of Australia's smallest national parks and yet a place of international significance.
An isolated coral atoll, it is part of the Cocos (Keeling) Islands, Australia's most remote island territory lying almost 2000 kilometres northwest of Perth in the Indian Ocean.
Pulu Keeling National Park has a number of unique features, including an internationally significant seabird rookery and an historic ship wreck. North Keeling Island is significant to studies of island biogeography because of its evolution in isolation and it continues to be a site of scientific research.
Pulu Keeling National Park is located on North Keeling Island which is a single C-shaped island with an inner lagoon. The lagoon itself is about half a square kilometre in size. The lagoon was once fed by the ocean on the island’s eastern side, but has now become brackish due to the lagoon entrance being blocked by natural deposition.
