AquaQuest Certified Diving


Great Barrier Reef day trips offer certified scuba diving that’s among the best in the world – as you deeply explore these warm, clear waters, you’ll be enthralled by richly colourful marine life.

From the beautiful tropical town of Port Douglas, you’ll head out to the Great Barrier Reef in luxury aboard our newest vessel, AquaQuest. On the way our dive instructors will brief you and help get your equipment set up, then it’s time to hit the water.

Our nine carefully selected dive sites at Agincourt, St Crispin’s and Opal Reefs will leave you spellbound. We’ll choose the best two sites to visit on the day based on weather conditions and visibility. There are swim-throughs, wall and drift dives that will appeal to every level of diver experience. You could be diving among coral gardens, or along reef walls, spotting marine life like tropical and pelagic fish, rays, turtles, wrasse, sharks and more!

Shared guided dives are available at no extra cost to help you make the most of your time on the reef. Our guides know where to go to see the best wildlife! Or if you’re feeling confident, simply set off to explore with your buddy.

Your certified dive day trip on board AquaQuest includes a delicious hot and cold tropical buffet lunch to keep you fuelled in between dives. Our vessel is purpose-built with a spacious dive deck and state of the art scuba diving equipment.

“I had the best day out with Divers Den! Their boat is super spacious, comfortable and felt uncrowded. The staff were awesome and looked after the certified divers really well. I loved the flexibility to be able to go with or without a guide depending on your preference and the dive sites we visited were awesome and super easy to navigate. Food was delicious. All in all, a stress-free, exciting and really enjoyable way to experience the Great Barrier Reef!”

“We were picked up at our hotel and the driver was early, waiting for us. The boat is beautiful and the equipment for scuba and snorkelling were top notch. The dive crew was very competent and attentive, pointing out many different fish including two small sharks. My wife loved the snorkelling. Overall I had a great time on the Great Barrier Reef.”

Medical and Altitude/Flying 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 by 2pm.
