OceanQuest Certified Diving


TRAVEL UPDATE: All overnight trips are currently on hold until 1st November 2020

Take the ultimate Great Barrier Reef overnight diving cruise from Cairns. Spend your days and nights deeply exploring the best outer Great Barrier Reef dive sites aboard our liveaboard vessel, OceanQuest.

During your Cairns overnight boat trip you’ll visit our colourful dive sites during the day… and 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. Choose to dive with a buddy or take a shared, guided dive for just $15 per person.

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.

Hearty 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.

“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.

Currently the rules state that for a single no decompression dive, you should not fly/go to altitude for at least 12 hours, or 18 hours after multiple dives. Divers Den recommends waiting a minimum 24 hours whenever possible. These are guidelines only, there is no guarantee that these recommendations will prevent decompression sickness. There are no current guidelines regarding diving after flying.

Altitude is defined as 300m/1000ft above sea level. Certain other tourist attractions around Cairns and Tropical North Queensland involve travelling to altitude. These include the Atherton Tablelands and the Skyrail Rainforest Cableway, so we recommend a gap between booking these experiences and any dive course or trip. Under normal circumstances, you should be out of the water on your last dive at 12pm (midday).
