About the Trip
Your Outer Great Barrier Reef adventure will begin with an (optional) early morning transfer from your accommodation to the boat- this can be from Port Douglas itself, or from both Northern Beaches and Cairns properties. The clear outer reef waters, beautiful corals and incredible marine life found at the Agincourt ribbon reefs, enable Poseidon to offer some of the very best possible day boat diving. Certified divers can enjoy up to 3 dives on a day dive excursion with Poseidon. This includes drift and wall dives, isolated pinnacles surrounded by pelagic fish and coral gardens with their endless variety of colourful wrasses, cods, parrot fish, clown fish, angel fish, clams and anemones, that make a healthy living reef so beautiful and exciting to dive.   With our wide variety of quality sites at over 25 different reef locations, we choose the best three sites of the day according to weather and tidal conditions. We use of a dedicated dive tender for drift dives.   All dives are guided at no extra charge and your Dive Master will brief you on the sites, equipment and safety procedures.
