The Great Barrier Reef: it’s one of the most iconic, most beautiful and most diverse locations on earth. Stretching from Cape York in northernmost Queensland down to Bundaberg on the central coast, this enormous living organism (the world’s largest) is nothing short of breathtaking.

Every tourist that visits the Great Barrier Reef contributes in a small way to the protection of this vast and remote wilderness. We are encouraged to experience for ourselves the wonders of this unique underwater ecosystem, and come away with a deeper understanding.
