Long Island is a member of the Whitsunday Island group off the east coast of Queensland, Australia. It is 9 kilometres (5.6 mi) in length and is at its widest point only 400 metres (1,300 ft). Long Island is the closest island in the Whitsunday group to the mainland of Australia, being only 1 kilometre (0.6 mi) from the coastline. A boat transfer to the island from Shute Harbour on the mainland takes 20 minutes.
Located on the island is Long Island Resort, overlooking Happy Bay. Most of the island is national park; there is 2,500 acres of tropical rainforest to explore and over 20 kilometres of bush walking paths. There is also a coral reef only 150 metres offshore.
