1 Best Sight in Great Barrier Reef, Queensland

For divers and snorkelers, the usually crystal clear waters off Lizard Island are a dream. Cod Hole, 20 km (12 miles) from Lizard Island, ranks among the best dive sites on Earth. Massive potato cod swim up to divers like hungry puppies; it's an awesome experience, considering these fish can weigh 300 pounds and reach around 6 feet in length. The island lures big-game anglers from all over the world from September to December, when black marlin are running.
