PADI Eco Open Water Courses


There’s nowhere better than the Great Barrier Reef to learn to dive and bring the largest marine park on earth, learn a little about the ocean too. If you want to contribute to ocean conservation whilst taking your PADI then Divers Den’s Eco Open Water course options are for you.

Spend your first two days at our purpose-built, five-star PADI career development and dive training centre in Cairns, then develop your dive skills on a once in a lifetime overnight stay on board our liveaboard vessel OceanQuest.

Our world class instructors will make sure you’re thoroughly trained in theory and in the pool before you set out for the reef. During your overnight trip, we choose amazing sites at the Saxon, Norman and Hastings reefs, so you’ll experience all the colourful treasures at these Cairns Great Barrier Reef dive locations as you gain valuable dive experience.

Spending the night at the Great Barrier Reef and waking to sunrise on the water, knowing you’re about to become a PADI certified diver is a thrill like no other! Depending on what course you select, you’ll also have time to do more training dives with your instructor, to fine tune your ability as a diver and cover areas such as bouyancy, navigation and night diving.

Integrated in your training will be the PADI AWARE specialty. The PADI aware speciality course is your journey to make a positive impact on the ocean. This course breaks down the barriers between diving and conservation opening the door to responsible marine stewardship for everyone.

A portion of your course fee contributes to the vital efforts of the PADI aware foundation from cleaning marine debris to protecting sharks and rays as well as establishing marine protected sanctuaries and assisting local initiatives.

Additional info

Prerequisites and forms

  • The minimum age is 10 to participate in a PADI Open Water Course (12 for advanced course). If the diver is under 12, we must be informed before the course starts, as a private instructor will be needed.
  • Anyone 15 or under must be accompanied by a Parent or Guardian during day trips on the reef. A 16 or 17 year old may travel without a Parent or Guardian if we have prior written parental consent and we have the relevant liability forms signed by a Parent or Guardian.
  • When enrolling in an entry-level recreational diving certificate you must complete the following self-assessed medical declaration forms before starting your training. The forms are similar and both are a Queensland code of practice requirement.

Medical Declaration for Entry Level Divers

Diver Medical – Participant Questionnaire

  • Medical certificate if required
  • Ability to pass a 200m swim and 10 minute treading water test

Medical and Altitude information

All scuba participants must meet medical questionnaire requirements. Some conditions or medications may prevent you from diving.

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. 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 12pm (midday) on our overnight trips and 2pm on our day trips.



“Awesome, guys! I took my open water PADI diving course with Divers Den, being one day theory, one day pool training, and 3 days/2 nights at their liveaboard boat OceanQuest. Our instructor was amazing. All the crew at OceanQuest were great, and the dives (and all help and service at the boat) were terrific. I would recommend, and I would definitely come back.”
