As there are tall cliffs surrounding the major part of the islet, throughout the years it was inaccessible, which in turn have no permanent residents. The island was formed by sand that was wind blown from sand dunes between the last two ice ages, unlike its two neighbors, Norfolk Island and Phillip Island, which are organic in origin.

Then the islet formed of cross bedded calcarenites that was cemented by dissolved lime into its present form. Previously there were signs of Polynesian people who have visited the island, however, during the Second Convict Settlement of Norfolk when the Australian and British settlers arrived in the area, the island was used mainly as a quarry and for timber, which later was abandoned.
