Lord Howe Island

Lord Howe Island is an irregularly crescent-shaped volcanic remnant in the Tasman Sea between Australia and New Zealand, 600 kilometres (370 mi) directly east of mainland Port Macquarie, and about 900 kilometres (560 mi) from Norfolk Island. It is about 10 km long and between 2.0 km and 0.3 km wide with an area of 14.55 km2, "of which only 398 hectares is in the lowland settled area".  Along the west coast there is a sandy semi-enclosed sheltered coral reef lagoon. Most of the population lives in the north, while the south is dominated by forested hills rising to the highest point on the island, Mount Gower (875 m or 2,871 ft).[7] The Lord Howe Island Group comprises 28 islands, islets and rocks. Apart from Lord Howe Island itself the most notable of these is the volcanic and uninhabited Ball's Pyramid about 23 kilometres (14 mi) to the south-east of Howe. To the north there is the Admiralty Group, a cluster of seven small uninhabited islands.
