Brilliant range of activities for varied ability levels. The semi submersible was wonderful for less mobile and mobile individuals and the talk by the South African man was informative and entertaining. All the staff were outstanding and gave me the confidence to snorkle and swim on the reef while feeling safe. Amazing experience. The talks by the staff on the catamaran to the reef were brilliant. Lunch healthy and delicious. A superb day ending in beautiful views on trip back to Port Douglas.

Really straightforward process. Booked online and went to collect the tickets 1 hr before the departure time from the Quicksilver office in the marina and then took the big boat out to the platform for scuba diving. All equipment was part of the package including an all you can eat cold buffet lunch and fruit!

From start to finish the staff on board the cruise where extremely tentative towards my sons who suffered sea sickness. Once out on the reef the day just flowed and before we knew it, we had to depart. What a magical part of the world that we saw. From the fish feeding demonstration to the semi submerged boat that takes you so close to the coral is something that my boys will remember forever.
