What a fantastic day! Great boat and crew plus wonderful snorkeling and equipment was to notch.
The crew were so attentive and engaging which made the trip a great experience. The boat was comfortable food and refreshments excellent. Comfort and safety are critically important to the crew.
Thank you jai and the team for an outstanding day.

Great snorkeling tour.
Emselb77, September 2026
We really enjoyed this snorkeling experience on the Mackay reef. The talk by the marine biologist was interesting as well. Definitely invest in sea sickness tablets as the trip back was quite rough.
