You’ll experience some of the most renowned reef sites, chosen from our moorings around the Norman, Saxon and Hastings Reefs based on the day’s conditions.

“The most amazing adventure ever! If you want to enjoy a wonderful day diving with the best instructors and supervisors, this is for you. The crew is very friendly and passionate. The dives were amazing, I don’t know how many different fish and reefs we saw, but they are going to be with me the rest of my life. Strongly recommended!”

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 by 2pm.
