OceanQuest Overnight Liveaboard Experience


Our liveaboard vessel OceanQuest is the ultimate Great Barrier Reef overnight experience from Cairns. Spend your days and nights exploring the best outer Great Barrier Reef dive sites aboard our floating accommodation, with snorkel, intro dive and certified dive options available.

When just one day at the reef isn’t enough, an overnight trip from Cairns gives you all the time you need. Visit our colourful dive and snorkel sites during the day, and at night everything from the air conditioned cabins with en suites, lounge and bar, are designed for your comfort.

Our three-deck, 35m catamaran is purpose built for a top class dive holiday, with a spacious dive deck, large open sundecks and hot, fresh water showers. All delicious meals are prepared by our onboard chef, including hearty breakfasts, lunches and dinners. Enjoy a well-deserved dessert treat after your day in the water!

Choose to stay from one to five nights on board, with departures available seven days a week.

Overnight (liveaboard) Great Barrier Reef trips from Cairns are truly a remarkable adventure. With more than 14 permanent moorings at Saxon and Norman reefs, and selected sites at Hastings Reef, snorkellers and divers of all levels can explore the reef and its diverse marine life from early morning to night.

At night, relax in the lounge and bar. Or if you’re keen for more undersea adventures, try a unique night dive experience like Sharks in the Dark or Fluoro Diving to make your time on board our floating reef hotel truly unforgettable.

An overnight experience is also the perfect time to complete or enhance your practical dive training at the outer Great Barrier Reef. With our expert dive instructors, you’ll be in the best possible hands.

“We stayed on OceanQuest for 2 nights and 3 days and it was truly an unforgettable experience. The staff were amazing – extremely friendly and professional at all times. The trip was well organised and the diving/snorkel spots were amazing. The boat itself was really clean and comfortable.”

– Hayley


“We wish we could’ve stayed one more night on the overnight liveaboard. The staff were really friendly and made it super enjoyable – Tobi was a great instructor – he ensured we were safe but also independent. I got my open water cert thanks to his good training. The rooms and food were great. I look forward to making it back one day.”

– Jessica

Medical and Altitude Info

All scuba participants must meet medical questionnaire requirements and some conditions or medications may prevent you from diving. These requirements can be found on our Can I Dive? page, and we strongly recommend reviewing before booking.

Queensland’s code of practice on diving states that for a single no decompression dive, you should not fly/go to altitude for at least 12 hours, or 24 hours if divers have had multiple dives per day for several consecutive days, or have made dives that require decompression stops.

Altitude is defined as 300m/1000ft above sea level. This includes going to the Atherton Tablelands (a popular local scenic attraction), so please be aware if booking tours to follow your dive trip. Under normal circumstances, you should be out of the water on your last dive at 12pm (midday).

Cancellation Policy

You can reschedule or cancel your trip any time up to 48 hours before departure with no penalty. Read our terms and conditions
