This UNESCO World Heritage Site is the world's biggest coral reef system, strecthing than 2,300 kilometres (1,400 miles) out from the coast of Queensland state. Its more than 900 islands and nearly 3,000 sub-reefs still offer an underwater utopia of colourful coral gardens and a riotous variety of aquatic creatures. You´ll will be in awe of nature's magnificence when snorkelling or scuba diving here, and there are plenty of other compelling aquatic activities, as well, including boating/sailing/yachting, kayaking/canoeing, stand-up paddleboarding, waterskiing, Jetskiing, and myriad other water spors.

Top destinations here include Fitzroy Island, Green Island, Lizard Island, Magnetic Island, and Orpheus Island. Special mention goes to the Whitsunday Islands in northern region of the GBR, with 74 lovely islands (part of six national parks) to explore. Out here you´ll find turquoise seas, teeming reefs, and palm-lined beaches such as Whitehaven Beach on Whitesunday Island, renowned for its spotless silica sand and crystal-clear waters. Youcan visit via cruise or sailing excursion, or stay at a range of resorts, campsites, and eco lodges.
