Opal Reef is a small outer reef system situated a few miles south of the Agincourt Reefs, making it a much easier and faster accessed reef. One of the sites you can visit here is Barracuda Pass, featured in the Lonely Planet Guide to diving and snorkelling in Australia.

Here on Opal you can expect  drop offs of up to 45 meters, swim-throughs and beautiful coral gardens that are perfect for the novice and first time snorkeller or diver.  You will encounter a full spectrum of aquatic wildlife including a pet Maori Wrasse, beautifully colored Starfish, soft & hard corals and Parrotfish providing a kaleidoscope of colors.  You will also see lots of Anemones and schools of large Pelagics as well as smaller Butterflyfish and Angelfish, numerous Giant Clams and much, much more.

Because of the diverse nature of Opal Reef it is in a highly protected area (a Green Zone) of The Great Barrier Reef Marine Park and classified for "Moderate" use allowing only limited numbers of people to visit each day. On days when the weather is less than optimal Opal Reef's close proximity allows for less travel time and provides excellent protection.  There are only 12 moorings allocated on Opal Reef and HABA is the proud owner of 2 of the original and best sites.  This means smaller groups and fewer boats.
