Going on the Ocean Freedom to the Great Barrier Reef was such a lifelong dream! The entire crew were absolutely incredible! Big shout to Ben our captain, Shea, Blair and Tee! The attention to detail by this crew granted us a memorable experience! My husband and daughter are snorkelers and I planned on staying dry on the boat but with the encouragement of Ben and Tee I had a lovely time snorkeling too! Tee was so patient, attentive and informative as she took me out snorkeling. Not once did I feel nervous which says a lot for this apprehensive swimmer/snorkeler! Tee was so attentive and made sure that I was enjoying myself and often kept close to my family for shared moments! Blair gave us additional time on the glass bottom boat when our first go was cut short by a passenger feeling seasick. Again, the attentiveness of this crew made our trip most enjoyable! Thank you for the great service! I would definitely recommend this to anyone wanting to enjoy the Great Barrier Reef with excellent care!

All the crew were professional, fun, and super friendly. I can’t swim at all, and it was my first time swimming in the ocean too, so I was honestly really nervous at first. But the crew looked after me so well, and it ended up being such an amazing experience. During both snorkelling and scuba diving, they always checked on me and made sure I was okay. They never rushed me, and everything was done based on how I was feeling. I struggled a lot at the beginning when I tried scuba diving, but Oliver was incredibly patient and stayed with me for a long time until I finally felt comfortable. I’m truly so grateful to him. If I ever come back to Cairns, I’ll 100% join Ocean Freedom again! If you want underwater photos, definitely come prepared! I wasn’t ready, so I missed the chance to take any photos underwater, kinda regret it

Pluses: friendly staff and well organized tour. Decent food and good boat Minuses: the spots for snorkling / diving very poor. If you have comparison with any average diving/ snorkling spot in the past you will be disappointed. Not much to see: few claims, nemo, a turtle and few other fish. Coral really bad, grey, not appealing and not much of it overall. Any snorkling in Egypt at the resorts even was far better than this one I dont want to believe Great Reef offers only that. I think the spots are badly chosen If you are for a swim: all good. If you want to experience diverse marine life: not the place

We’ve been on dozens of scuba/snorkel tours around the world and this is one of the best! Of course the Great Barrier Reef is amazing, but this team’s knowledge, friendliness is second to none. They are truly superb!

Ocean freedom is simply the gold standard for GBR snorkeling and drive tours. Of course the reef was fantastic the difference is the people, you can tell this is a family run business with the care they take from start to finish. Their attn to detail for our safety all the while making it fun as only the Aussie’s can. Btw our Skipper Blair was outstanding

Great team, great trip. The weather wasn't the best, but the team did their absolute best to make our day. They were supportive, offered a good laugh and educated us on the ecosystem.

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.
