OceanQuest Certified Diving


Take the ultimate Great Barrier Reef overnight diving cruise from Cairns. Explore the best outer reef dive sites from our liveaboard vessel, OceanQuest.

During your Cairns overnight boat trip you’ll spend your days exploring the reef, fuelling up in between dives with hearty meals to keep you going. At night, the fun continues with our exclusive Sharks in the Dark and Fluoro Diving experiences.

Overnight (liveaboard) Great Barrier Reef trips from Cairns are truly a remarkable adventure. With our exclusive moorings at Saxon, Norman and Hastings Reefs, certified divers can encounter a colourful array of marine life including fish, corals, turtles and more.

There’s so much diversity at different times of the day on the reef, and on an overnight experience you can experience dives from early morning to night. At Divers Den your diving experience can be catered to your needs, we offer the option for certified divers to dive with a buddy or with one of our professional guides for a small extra cost, giving you the independence to explore the Reef how you like!

In between your Great Barrier Reef dives, you’ll have plenty of time to rest and enjoy yourself on board our floating accommodation. From the comfort of your air-conditioned cabin with en suite bathroom, to the relaxing surrounds of our sun decks, lounge and bar, you’ll love your Divers Den liveaboard experience.

Meals are freshly prepared on board by our resident chef, and there are snacks and drinks available to keep you fuelled and ready to explore the reef.

While you’re on board, consider enhancing your scuba diving skills and qualifications. Add a PADI advanced open water course or the Enriched Air (Nitrox) specialty when booking.

“My new favourite liveaboard agency out of Cairns. From start to finish, what an excellent experience! Everyone was helpful, patient, and took their time with everyone to make it a very personal and enjoyable experience. At each dive site, they made sure to find something unique and interesting to look at and how to find it. I used a guide for most of my dives and they were very affordable and took the stress out of navigation, so I could enjoy the dive more.”

– Ambar


“The friendliness and professionalism of the crew was truly above and beyond any expectations. The accommodations were practically luxurious on the liveaboard, and all guest needs were provided for quickly and efficiently. Divers Den has a quick and efficient system for making sure all of the little details have been addressed, enabling the guests to just relax, dive, socialize, rest and recover.”

Medical and Altitude Info

All scuba participants must meet medical questionnaire requirements. 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 from your last dive of the day at 12 noon.

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.
