Australia is known for its unusual animals, rich marine life, fascinating culture, Crocodile Dundee, Vegemite and very distinctive accents. But when it comes to visiting below the ocean’s surface, one particular part of its marine heritage stands out above all others: The Great Barrier Reef. Rated as both Australia’s and one of the world’s top scuba destinations, diving the Great Barrier Reef should be at the top of any true dive enthusiasts’ must-do list of places to visit. Other highlights in Australia include destinations like the much sought after Rowley Shoals in Western Australia, and great white shark cage diving in South Australia.
