Moreton Island, Queensland, Australia

At 23 miles long and 72 square miles in area, Moreton is the third-largest sand island in the world. It is part of a sand barrier system that includes the larger Fraser Island, and separates Moreton Bay from the Coral Sea about 27 miles north of Brisbane. Moreton Island National Park encompasses 98 percent of the island, where visitors flock to experience activities such as “sand-tobogganing” down the slopes of 920-foot Mount Tempest, the highest stable coastal sandhill on earth. They also enjoy fishing, kayaking, surfing and snorkeling over the Tangalooma Wrecks offshore. Tangalooma is the largest of four small towns on the island’s west coast. It was an active whaling station from 1952 until 1962. There are no roads on Moreton Island, so visitors get around by 4WD vehicles or ATVs. A popular site to visit is the picturesque red-and-white Cape Moreton lighthouse, built in 1857 and Australia’s oldest.
