Diving Details

Personally I love taking the drive to Port Douglas and diving the reefs at Agincourt as you are on the very outer edge of the Great Barrier Reef section called the Ribbon Reefs.  If you like the idea of a liveaboard dive trip then let me know.  Your day on Poseidon will offers you to experience some of the very best possible day boat diving in clear outer reef waters, beautiful corals and incredible marine life found at the Agincourt ribbon reefs and only 70km north east of Port Douglas.
