One of the most famous reef systems in the world, the Great Barrier Reef is world
renowned for its abundance of marine life and world-class diving opportunities. When I was there, I saw turtles, sharks, vibrant coral, and beautiful fish (even a fish pooping, which was as weird as it sounds). It was everything it was cracked up to be. You can spend one day or a few diving this reef. Though everyone leaves from Cairns, leaving from Port Douglas will get you to less crowded dive spots.
