Quicksilver Cruises
Departing from Port Douglas, your 90-minute high speed catamaran takes you directly to Agincourt Reef. The permanent pontoon moored here provides a sheltered base. During the trip a snorkeling demonstration will get you ready for your adventure, and the staff will take you through your options for the day.
Agincourt Reef
You'll have around 3.5 hours to enjoy the reef at your leisure. Grab a snorkel and fins and hit the water on your own, or join an optional guided snorkeling tour with a qualified marine biologist. Snorkeling is a great way to explore the Great Barrier Reef, and there are friendly staff on hand to show you how. Prefer to stay dry? You can explore the stunning reef from the comfort of a semi-submersible submarine. You'll take a leisurely cruise through colorful coral gardens, giving you a snorkeler's view of the marine life without getting wet. For a little more adventure, why not try an introductory scuba dive. or a unique Ocean Walker Helmet Dive - no diving experience necessary. We recommend you book this reef trip on your first full available day. You then have the opportunity to be flexible and change your travel date if you wish. Your booking can be changed at no additional cost directly with the operator once you are in Cairns.

Everyone we encountered on this excursion was absolutely wonderful. Truly the most amazing experience and everyone was so helpful and knowledgeable. My father was so anxious about snorkeling and Scotty put him at ease and was so patient with him helping me put on his mask and getting him comfortable in the water. Flick was wonderful answering our questions and Seb was so wonderful to talk with and so knowledgeable. We had the best time and this has been the highlight of our trip to Australia!

The lifeguards, staff and everyone in quicksilver cruise were professional and well organized. It was a big group and everything went well. The helicopter ride would have given a overall better experience of the massiveness of great barrier Reef. ( we did not do that). The submarine was great to see all the corals up close. We did snorkel in a small area close the pontoon boat and it was Ok.Did not see many fish..

Great for swimmers and non-swimmers. Submersible had good views of reef and good commentary. Snorkeling was within a corded off area. Watclaws. very nice temperature for snorkeling with some spectacular coral and fish viewing, including some colorful giant clams.

What an experience it is definitely worth so many corals and colorful fish in big and small both snorkeling and diving. Perfect organization and supply there is nothing missing. Many thanks to the Divemaster Gordo who made our experience a very special day. We felt very comfortable

Had a fabulous time on this trip to the Great Barrier Reef. Boat is lovely, crew were fantastic and felt very safe. The submerged vessel is good and we also did the helicopter ride which was amazing. The buffet lunch was excellent .

Quicksilver was an over the top snorkeling experience. We’ve been on many snorkeling trips and have never had the ease getting in and out of the water. Saw so much coral and so many fish. The crew were energetic, helpful and knowledgeable. Snorkeling the Great Barrier Reef was a Bucket List check off for me and I couldn’t be more delighted. Lunch was so so.

Overall ok but the older guy handing out the suits was rude. It was a scramble and he threw me an XXL suit. When I tried it on the crotch was halfway down to my knees and very baggy. I politely asked if it could be exchanged for a medium (I'm size 12). He ranted loudly about how he does this all the time and once I have tried on a suit (over togs) it couldn't be returned and how the next size down would be too small. I was mortified and embarrased. I explained that it was very very baggy. He threw me a size small suit (there were mediums there) and said that won't fit and you can't return it. Well, it did so I didn't need to return it but it really ruined the whole atmophere of the day. It's alot of money for a day we were so looking forward to to be body shamed - Im not even going to say unnecessarily because it shouldn't happen to anyone! I understand he was busy and to be fair it is a bit of a production line but he should probably be doing a course in hospitality/tourism and manners.

The staff was excellent and the boat was very clean. Winds and the sea were calm on the day we went out so it was a nice trip to the reef. We’ve snorkeled at other places on the reef and were hoping for more sea life variety but it could been the day we went.
