Nepean Island (Norfuk: Nepeyan Ailen) is a small uninhabited island located about 800m south Norfolk Island in the Southwest Pacific. The island is about 10 hectares in area.[1] The island is uninhabited due to its small size and tall cliffs flanking it, making it nigh on impossible for boats to land there. It forms part of the Norfolk Island National Park, along with Norfolk Island and Phillip Island. It is part of the Australian territory of Norfolk Island and is included in the Norfolk Island National Park, as is nearby Phillip Island, and about 10 percent of Norfolk Island proper.

History[edit]

Unlike Norfolk and Phillip Islands, Nepean is not volcanic in origin, but was formed by wind blown from sand dunes between the last two ice ages. The sand grains cemented together by dissolved limestone from calcareous sand which formed aeolianitic calcarenite.[1] Although Polynesian people were known to have settled around Kingston, no evidence of Polynesian settlement has been found on Nepean Island. The island was first cleared during the First Settlement.[1] Nepean was used as a quarry and for timber during the Second Convict Settlement of Norfolk Island, and was abandoned as a site during that settlement.[1] Remaining stone steps can be seen on the east coast.[1] It is thought the island was named in 1788 by Lieutenant Philip Gidley King for Evan Nepean, Under Secretary of the Home Department of the United Kingdom. However, it may have been named after Captain Nepean, who commanded the colony when King sailed to New Zealand in the Britannia to return two Māoris.[1]

Flora and Fauna[edit]

The island is made of calcareous rock dating from the late Pleistocene and is a breeding site for several species of seabirds.[1] Before being cleared in the 1790s, the island was home to about 200 Norfolk Island Pines. Today, native plants present on the island include Pigface, Native Spinach, Moo-oo, Native Flax and Native Rush.[1] The Masked booby breeds on site during the summer. From July to December Little shearwaters breed on the island. Other birds such as the Whale Bird, Grey noddy, Black noddy, Wedge-tailed shearwater, Brown noddy and Red-tailed tropicbird also breed on Nepean Island. It is a refuge for the endemic Marbled Gecko, which is now extinct on Norfolk Island. It is also home to the Phillip Island Skink.[1] The island is home to Little Nipper Landcrabs and Freshwater crabs. Green turtles are often seen off the coast of the island.[1]
