Reviews / Testimonials

“I have just completed my IDC with Divers Den. If you want the best, you are in the right place. Professional, thorough, and overall one of the greatest experiences of my life. I cannot recommend doing your IDC with these guys more.

Charlotte and John are incredible. The amount of work they put into you to ensure you pass – this should be reason enough to sign up.

All in, if you want to have the best 3 weeks, meeting amazing people, with the best mentors and learning on the GBR (2 nights live-aboard) – sign up now. Will be the best decision you’ve made.”

– Anna Glassey (Feb 2024)


“Doing my ITP/ IDC with Divers Den prepared me for more than just the IE, it prepared me for many of the challenges I now face as a dive instructor every day. I feel confident passing on these skills to my students and I would recommend taking the next step towards Padi Pro with the amazing team at Divers Den.”

– Remily, 2019 (who is now a course instructor at Divers Den!)

Medical & Altitude Info

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

It is required by Queensland law that you must wait at least 24 hours after diving before going to altitude or flying – there is no guarantee that this requirement 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) on our overnight trips and 2pm on our day trips.
