5.00Skipper Tim and his crew provided absolutely spectacular service to all 15 passengers. Snorkeling in the GBR topped my bucket list. Mission accomplished Seastar. The boat itself quite shipshape. The captain ensured safe and comfortable conditions for our reef explorations. The food provided exceeded my expectations. Hats off to Danielle for the tow and clown fish sighting.
Fabulous way to snorkel the Great Barrier Reef

5.00The boat, the staff, the experience, were all terrific. It’s a small boat with about 30-35 people so everyone gets personalized attention. We stopped at 2 locations with exquisite reef snorkeling and views at both. I am not a good swimmer but that was not a problem with guided snorkeling holding a ring. There is also a glass bottom boat. The lunch spread was sumptuous and the staff were very friendly.
A must book Barrier reef experience.

5.00The most incredible day trip, even better than I could have imagined. The staff are friendly, knowledgeable and patient. The snorkelling tour was incredible and the staff are so attentive. The lunch and snacks were lovely. I cannot recommend this trip and Seastar highly enough.

5.00We had a fantastic day out on the reef with Seastar. The staff is so nice and helpful, they really do everything for you to have the best experience ever. We got to see amazing coral reefs and the most beautiful fishes. We were in Cairns eight years ago (visiting from Sweden) and we went out with Seastar then also. To choose Seastar this time aswell was completely self evident. Again - it was a great choice. So, to the wonderful - see you again in eight years. Thank you.
FABULOUS!!

5.00We had a great time. The boat was comfortable, with a maximum of 36 guests on board. The snorkelling at both sites was really good, with lots to see. Lunch was delicious, plus cake and fruit in the afternoon. The staff were friendly and helpful, a good team. We would definitely go with Seastar again and highly recommend them.
Crew is knowledgeable and...
