We went on the Ocean Free Tour today. It was absolutely fantastic! Like really worth the money, from start to finish every part was really well thought through and quality. We had the option to snorkel or dive, we had a fabulous lunch provided with snacks throughout the day like cheese and biscuits/cake/ fresh fruit platters. The team were SO accommodating and extremely knowledgable. We would highly recommend Ocean Free in Cairns. We were all super impressed.

We are not strong swimmers but wanted to experience the Great Barrier Reef and we are so happy we booked with this company (Cairns Premier Reef & Island Tours, a family owned business) .. from the moment we arrived we were looked after so well. The crew amazing, young and very knowledgeable and just the best bunch of people. Having never swam in the ocean or snorkelled, we were very nervous but we were guided in by a lovely young man called Ollie (thank you Ollie, you were just the best!) he stayed with us on both dives and kept us informed, calm and happy. It was just the best experience of our lives! The GBR was so beautiful and we felt honoured to be witnessing. The boat (Ocean Freedom) was very comfortable and a delicious breakfast, lunch, afternoon cheese and biscuits served which was great. We met really lovely people and the atmosphere was friendly and fun. At the end of the trip the crew lined up and shook our hands, as I said just the best bunch of fine young people. I was in tears as it was really the most memorable and wonderful day! ❤️

Perfect day. Great knowledgeable staff. Small boat experience lead to lots of individualized attention. The guides were nearby the whole time in the water for safety and to spot for fish and provide information. The food was very good and plentiful. Danish and fruit when you board, great lunch buffet lunch and snacks through the day. Highly recommended.

I had an absolutely amazing experience swimming in the coral reef. From the moment we arrived, the guides were incredibly supportive, patient, and reassuring, which made me feel completely relaxed and confident in the water. Their professionalism and kindness truly stood out. Everything was thoughtfully provided on board to ensure everyone had a comfortable and enjoyable day — including motion sickness tablets, drinks, and plenty of delicious food and snacks throughout the trip. We were treated to breakfast, lunch, cake, fresh fruit, and crackers with cheese, which was such a lovely touch and kept everyone well looked after. The views of the reef were absolutely breathtaking — vibrant, colorful, and unforgettable. Being able to experience this natural beauty in such a well-organized and friendly environment made the day even more special. Overall, this was an unforgettable experience. The tour guides and crew were fantastic, attentive, and genuinely passionate about what they do. I couldn’t recommend this tour highly enough — truly a perfect day on the water!

The staff was excellent. The food served was excellent. The one issue which I can’t blame them for, was the rough waters, which created poor visibility. Saw some coral and some fish(more at the second stop than the first), but not what I had imagined. They had to be aware of the conditions but I guess I can’t expect them to cancel the whole trip and loose all of that revenue. Had I been aware of the conditions ahead of time, I probably would have canceled.
