When people think of Australia, they think of the Great Barrier Reef.
Who hasn't dreamed of swimming above multicoloured corals, alongside turtles and amid tropical fish.
The Great Barrier Reef, a UNESCO World Heritage site, is a living wonder lying 16 kilometres off the coast and stretching 2,000 kilometres along Queensland — it is so vast it can be seen from space.
You can also admire this patchwork from above, like an oasis in the middle of a desert, whether by helicopter or seaplane.
