Full description

Climb aboard the Silversonic catamaran for a full-day cruise to Australia’s renowned Agincourt Reef on the edge of the Continental Shelf. Dive into the turquoise waters for a refreshing swim or enjoy snorkeling at 3 different sites to see the coral formations and the diverse marine life. 

The ultramodern 95-foot (29-meter) Silversonic catamaran is custom-designed for small groups of adventure-minded people. You will spend over 5 hours at the reef, visiting 3 different Agincourt ribbon reef sites, each chosen for its visual and ecological diversity. First-time divers can enjoy up to 2 dives and take the plunge in complete confidence with an experienced dive instructor. Certified divers will enjoy up to 3 dives, all guided to maximize your experience.

Was very fortunate to have great weather and calm seas (mid Oct) The day was "as per brochure" with all the stars turning up ... Nemo and friends Bruce (reef shark) and Crush (a very relaxed green sea turtle) Seriously it was amazing snorkelling amongst the plentiful, colourful, varied reef fish and other marine life amongst beautiful coral formations like underwater mountains. I spent approx 5 hours in the water and was still in awe of the beauty I was seeing. When on the boat the organisation was smooth and informative, with ease of preparing to snorkel, sessions to educate about the reef and some of its coral and marine species. Staff were knowledgeable and assisted with whatever was necessary. The ground crew at the "check in" office were also really helpful. It was a truely a great day out!

I came on this trip with my family - my parents (in their 70s) had never snorkelled before and were nervous but wanted to experience the Great Barrier Reef. The staff were amazing and assisted my mother in the water, building up her confidence and allowing her to experience the reef - it is an experience she will not forget! They were knowledgeable and there was plenty of food available throughout the day.

Great tour. We were picked up at our hotel and taken to the harbor. We were told the ride out to the reef would be very rough and warned in advanced; we could not change dates due to our schedule. Several people got sea sick on the way out to reef and the crew was very helpful with all and make sure everyone felt good. They really warned us to take sea sick pills one our before our return and once again were veer helpful to the few who got sick on the renter. We did 3 sports on the reef, everyone very helpful and the snorkeling was amazing. Would not have missed this event if they told us a hurricane was approaching.
