Great day on the water!

5.00Snorkel tour was awesome. Service and education were great and you can tell they take safety very seriously. Stinger suits were provided and so was glass bottom boat ride. Food and snorkel spots were very nice. You can tell the boat is older but it was great to have less than 25 people on the boat. Much better than the crowded ones you’ll see leaving the marina. Thank you for a great day!

5.00From the moment we stepped onboard, the Seastar crew made the entire day unforgettable. They were amazing, caring, fun, and just overall incredibly cool people. You can tell they truly love what they do — they made us feel welcome, safe, and taken care of every single second. Our group wasn’t huge, which we loved, because the crew gave so much personal attention to everyone. Whether it was snorkeling help, reef facts, jokes, checking on how we were feeling, or just making sure we were having a great time — they were on it. It never felt rushed or crowded; it felt personal, genuine, and so special. And I have to give them a HUGE shoutout for being absolute legends during our surprise proposal. Not only were they the most trustworthy secret-keepers, but they went above and beyond to help make the moment magical. I will forever be grateful for how seamlessly they helped pull it off. Honestly, we wouldn’t just come back to see the Great Barrier Reef again — we’d come back to see them. The crew made the experience what it was: magical, memorable, and full of laughs. You can’t fake that kind of energy. I would recommend Seastar to anyone and everyone. If you're debating between the big boats and Seastar… don’t. Choose the crew that actually cares. Choose the crew that makes you feel like family. Choose Seastar.

Pleasant trip with a few challenges:)

4.00The crew was very kind and the food was good, but the snorkeling location wasn’t particularly rich in marine life. The fast ride and rough sea made some passengers feel unwell. I normally don’t suffer from sea sickness, but this time it was quite intense, and I had to buy medication on board. There were also guided snorkeling talks, but due to the rough conditions it was difficult to hear the guide in the water. That said, pleasant trip with a few challenges :)
Top 3 tours for our visit toCairns, Australia.beautiful day!!

5.00First time on the reef. Fantastic experience with fantastic people. I was snorkeling but my wife came along for the ride (she has always said she was afraid of the water). Well, on the second reef, the staff convinced her she would be in good hands to get into the water and at least float and see what was on the reef. Believe it or not, they helped her get over her fear and she was so happy she sent pictures to all of her friends. They could not believe seeing her with her dive suit, mask and snorkel floating in the water with one of the staff people. It was great to watch. Now she wants to try it again (this time closer to our home in Miami Florida). Anyway, they are the greatest people and the lunch provided was great with many options and we had a few brews on the way back in. Overall, a day we will never forget.
Great way to see the Great Barrier Reef

5.00The tour took us to two different areas of the reef. The guides are excellent, focused on safety and experiences of the customers. Very good casual lunch with vegan options. The snorkeling was great - many species of fish. You can snorkle by yourself or follow a guide around the area.
Best of times

5.00Diving on the Great Barrier Reef as to be expected was fantastic. Great friendly staff and really good food at lunchtime. The day with SeaStar was snorkelling, glass bottomed boat and diving for those who were qualified.
