Great Barrier Reef pontoon - Amazing trip to outer reef pontoon via Green Head. Perfect weather calm and no wind. Not too many people snorkeling on top of each other. Lunch great

Fun trip to see the Great Barrier Reef - Very good crew on this excursion! Loved the Great Barrier Reef. We were not going to be back in time to board our ship due to a time change for boarding. We took the helicopter ride that was offered on the excursion itself and loved it!! Flew over the Reef and got back to Cairns in plenty of time.

Despite being a cloudy... - Despite being a cloudy day the water was warm and we thoroughly enjoyed our day on the Reef. Well organised nad would do again.

Highly recommend Viator for anyone planning their next adventure — reliable, organized, and truly customer-focused. - I appreciate how professional and responsive the team was throughout our communication. It really made a difference during a stressful situation.

Great company - The organization and crew were fantastic. They were very attentive to each guest. It was a great day.

Excellent! - Amazing staff and service! Really nice instructores and facilities! Good lunch and the cheese and biscuits on the way back was also a nice way to finish the experience. Thank you!

The knowledgeable guides provide valuable insights into the reef's ecosystem, making this adventure both educational and unforgettable.

Great experience - Staff was nice, reef was stunning, snorkel/scuba diving was world class and helicopter ride was amazing. If I had it all to do over I would request a helicopter ride with no more than 4 plus the pilot. We had 6 which took away from the experience. The group after us was a party of two. They could have easily of had two groups of 4. Overall a great experience.

Catering was poor... - Catering was poor quality. The underwater observatory was crammed and hardly saw anything. The only experience I enjoyed was the skoobydoo and it was not included in the package. I had to pay $185 extra for that.

An overall highly disappointing experience - I booked a trip with Great Adventures, pro driver Cairns to the outer reef. I am a scuba diver, certified instructor in the CMAS system with over 300 dives and having myself guided and led numerous divers underwater. I have dived internationally in numerous locations including tropical, temperature and cold water locations. I had never done the great reef and needless to say my expectations were high. whereas I have nothing to say about the overall organisation of the tour (Very professional) and the friendliness of the staff, my driving experience was poor at best. First, driving the great reef is a money making machine. The companies are not so much about the experience than they seem to be about the number of people who pay. In short, I did three dives. 40 minutes (not a minute more) each. My first five included 10 minutes of sand time when I could see coral on the side. My dive guide later justified this was due to current, a poor excuse given the relatively weak prevailing current. However, the second and third dive were a little better. But all dives were about quickly zooming past reefs rather than taking time to observe... And especially being back after exactly 40 minutes. Second, European divers be aware. This is the typical PADI run business, where much of the recommendations make no sense. You turn back at 120 bars when you are less than 15m deep on average for said security reasons, but at the same time- if you are low on air, the security brief says the guide will wave you bye bye and you surface on your own and make your way to the ship so that others let enjoy the rest of their sprint experience. Not that it would matter, since most of us surfaced with 100 bars or more. Under water, you are solo if you did not come with a buddy. Being an instructor, I do not mind as I have a good idea of what to do if something goes wrong. For the less experienced diver, this may be somewhat distressing. No DSMBs used to surface, but you do have one without a rope you can inflate at the surface... (What is the sense in that, except if you have surfaced half a km full the boat). Third, I did not have my own gear with me so was forced to take the full gear package... I did post the full price, but for what gear? A half battered half wetsuit, regs that are rubbish ( luckily dives are not deep) and flippers that could barely be named as such (I hope you like useless effort)? The whole experience was hurry, hurry, hurry, We're here to make money. Thanks for your cash, well take some pictures of you underwater holding a ridiculous reef sign, pay some more money, and so long. In short, beginners will likely find the experience great. For experienced divers ( especially those averse to PADI / SSI training), I would normally say avoid. But since there doesn't seem to be that many other options to dive the outer reef, at know what you have paid for. For me that had high expectations, it was an overall highly disappointing experience. I much more recommend Polynesia for a tropical experience, and besides, the reef is in a much greater health
