Your Hosts

Professor Simon Mitchell & Captain Trevor Jackson of the ‘Centaur’ fame. In 2002 Trevor & Simon rewrote history books when they dove to 178m for 5 hours to discover the truth about this famed hospital ship. This dive is still unparalleled in Australia. Several seminars on hyperbaric medicine & deep diving.

Holmes Reef - Coral Sea

Cruise 120 miles east to the deep clear Coral Sea territory. At ‘Amazing’ descend to a ‘fishbowl’ of shallow white sand with a myriad of marine life. The shark dive attracts grey reef & silvertip sharks. Spiral down ‘Nonki’ pinnacle through fish schools to caves festooned with soft corals at 35m.

Bougainville Reef - Coral Sea

Bougainville has something for everyone. Plummeting clear blue waters, giant Queensland Groupers, wall dives, drift dives and more. There’s a wreck to visit and canyons to explore. A remote reef which is rarely visited and awesome to see. Sites we will visit: Dungeons & Dragons, Southern Wall and Silver Slope

Osprey Reef - Coral Sea

Witness the amazing Amphitheatre shark frenzy. You can photograph these sleek high order predators at close- range, or not so close, you choose! Spectacular topography, visibility & pelagics at False Entrance. Sites visiting: South Osprey, North Horn, Admiralty  Anchor and more…

Deep Sea Arcade

Flagship technical dive, Deep Sea Arcade is a spectacular 400 metre long overhanging cliff face that defies belief. In depths ranging from 55 to 75 metres, this site is suitable for advanced technical divers. Bring your camera and capture your own ‘cover shot’ of the stunning fan formations. Recreational divers will be able to dive the West Wall at North Horn.

Great Barrier Reef

This isn’t deep reef, but it’s some of the world’s best tropical reefs and a must see on our itinerary. We’ll spend the last day exploring and enjoying the diversity of the Great Barrier Reef’s Ribbon Reefs, visiting some prime sites including Flare Point and Steve’s Bommie. Get your camera ready.

Returning to Cairns

Disembark Thursday 8:00am at Trinity Wharf, Cairns.
