  • Fabulous experience!

    Claire F wrote a review Aug. 2020
    We visited Australia in March and wanted to go to the Great Barrier Reef. I was unable to dive due to perforating both my ear drums however my partner did 3 dives. I snorkelled on all 3 stops and the views were amazing…
  • Certified diver day tour

    Crockery wrote a review Jul. 2020
    You pay a basic price for the day trip, and then add the price for one, two or three dives, depending upon how many you want to do. I wanted to do two dives and one snorkel, so that’s what I paid for. I was very happy with that…
  • Best diving spot on the reef

    Adéla S wrote a review Jul. 2020

    Lucy T wrote a review Jul. 2020
    Was lucky enough to do the three dives on the reefs with master diver Jan. Was such a magical day and enjoyed three relaxing dives at three different reefs. Also lucky enough to see a grey reef shark and several turtles.
