The Whitsunday Islands are a group of 74 islands that lie off the coast of Queensland, Australia and form part of the Great Barrier Reef. The islands are one of the most popular Australian tourist destinations. The vast majority of islands are designated national parks and major attractions include access to coral reefs for snorkeling and diving, pristine beaches, especially Whitehaven Beach on Whitsunday Island and clear aquamarine warm waters. They are well connected by two major airports on Hamilton Island and the mainland town of Proserpine. Over half a million visitors come to the Whitsundays each year.
