The Great Barrier Reef is one of the 7 natural wonders of the world, a World Heritage listed reef system comprising over 3000 individual reefs. This hugely biodiverse ecosystem is home to an abundance of marine life, coral cays and tropical islands surrounded by sun-drenched golden beaches. It has become one of the most highly sought after tourist destinations in the world, so there is no shortage of activities available to help you explore the stunning area, including snorkelling, diving, scenic flights, cruises and whale watching voyages. The Great Barrier Reef is usually accessed via the main ports of Airlie Beach in the Whitsundays and the tropical city of Cairns, although the coast of Far North Queensland harbours many other beautiful towns that provide tours to the reef.
