Lord Howe Island (/haÊŠ/; formerly Lord Howe's Island) is an irregularly crescent-shaped volcanic remnant in the Tasman Sea between Australia and New Zealand, part of the Australian state of New South Wales. It lies 600 km (320 nmi) directly east of mainland Port Macquarie, 780 km (420 nmi) northeast of Sydney, and about 900 km (490 nmi) southwest of Norfolk Island. It is about 10 km (6.2 mi) long and between 0.3 and 2.0 km (0.19 and 1.24 mi) wide with an area of 14.55 km2 (3,600 acres), though just 3.98 km2 (980 acres) of that comprise the low-lying developed part of the island.
