Australia's Great Barrier Reef - the world's largest marine park and most extensive reef system - is an incredible network of islands and coral-covered fringing reefs, mangroves and sand cays.
You can explore the submerged mountaintops of the Coral Sea reeds, observe humpback and minke whale migrations, see huge cod and dive into history as you investigate the Yongala's watery grave.
There is excellent visibility in the shallow waters and the thriving local dive industry gives world-class and accessible diving and snorkelling for any level of expertise. F
