The trip to the pontoon at the Great Barrier Reef was terrific! It was very well - organized. Safety, efficiency and enjoyment were all well-planned. An amazing place!

Itinerary

Agincourt Reef is a fantastic base for discovering the outer Great Barrier Reef, featuring a permanently moored pontoon for easy underwater exploration. Your full-day adventure begins with a 1.5-hour high-speed catamaran cruise to the edges of the reef. During the voyage, relax on the sun decks, take morning tea and watch a snorkeling demonstration.

When you arrive at Agincourt, splash into the water from a submerged platform to snorkel among tropical fish and coral gardens using provided snorkeling equipment. If you prefer to stay dry, you can still explore the world-famous reef from an underwater observatory or with an included semi-submersible boat tour.

Many optional activities allow you to customize your reef adventure (additional expense). Go deeper with an introductory or certified scuba dive, take a guided snorkeling tour led by a marine biologist, embark on an Ocean Walker helmet dive or get an aerial perspective on the reef with a thrilling 10-minute helicopter flight.

Savor a tropical buffet lunch onboard the catamaran midday, and recharge with afternoon tea. After approximately 3.5 hours at the reef, relax on the return ride to Port Douglas.

See Itinerary below for a complete description of all included and optional tours and activities. Select the guided snorkeling tour, introductory dive and Ocean Walker at booking; other activities are payable direct on the day of your tour.

The weather was a bit nasty but fun was had at the reef. The crew members were very friendly and helpful. The buffet lunch served was very tasty and plentiful. Even though the ride to and from the pontoon was rough I would definitely recommend the tour.

Well managed cruise

Abhishek_P, Apr 2026

The cruise was very well organised with high level of attention to details. They even had powered snorkelling masks which was helpful for me as I have a high eye power. The crew were very friendly and always reaching out to check on us. Semi submersible tour was amazing, especially for those for whom getting into the water can be difficult.

Worth every penny

Kathy_T, Apr 2026

A fabulous day out to the reef. Once in a lifetime trip for us. Everything was very well organised. The staff went above and beyond and a great day was had. The reef was beautiful and we are so glad we made the trip.

Great snorkeling trip!

Denise_A, Apr 2026

Excellent tour with plenty of activities on the platform once off the catamaran. Buffet lunch was sub-par and seemed to cater more to Asians.

Fab time

Joanne_H, Apr 2026

Great service, friendly and professional staff. The buffet was plentiful and caters for everyone. Clean facilities.

Great boat ride to The Great Barrier Reef, but too many people!

Lisa_C, Apr 2026

There were too many people on this trip to enjoy the snorkeling. I wish I had chosen one of the smaller excursions so that we weren’t on top of each other on the water.

We went with our two year...

Palesa_N, Apr 2026

We went with our two year old. The staff was amazing so attentive even getting me a drink and making me lunch whilst my toddler slept on me. They were so helpful checking times for different activities and ensuring you get to experience everything you wanted to. Even with a 2 year old in tow we were able to snorkel the Great Barrier Reef. Go through the underwater tunnel, ride in the submarine and also take a lovely 10 minute helicopter ride to see the Great Barrier Reef from the sky. Absolutely unbelievable and well worth the extra money. Lunch was really delicious too and everything is so well thought out. If you’re visiting port Douglas it’s worth every penny.

A 5 star operator!!

Amazing Reef

Fiona_M, Feb 2026

Great experience snorkelling over so many beautiful kinds of coral and fish. Was supplied with very good equipment.

Response from Host, Mar 2026

Great Barrier Reef - must see

Meena_s, Feb 2026

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 reef experience for all

Allan_R, Feb 2026

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.

Response from Host, Mar 2026

Thank you for your positive review, we hope to see you back with us for more snorkelling Allan!

This is a Definite!

Debbie_S, Feb 2026

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.

Response from Host, Mar 2026

Thank you for taking the time to share your experience! We’re thrilled that we made your snorkeling adventure on the Great Barrier Reef so enjoyable and stress-free.

Great Barrier

Susan_M, Feb 2026

This is a can’t miss experience! We enjoyed the staff immensely their attention to details was great! This was the best snorkeling! Alana also helped us out after tour as we had a flat tire. Can’t say enough great things about today’s tour!

Response from Host, Mar 2026

Thank you for your lovely review of our day with us on board Quicksilver! We're glad our Reservations team member Alana could help with your flat tire too!

Timothy_S, Jan 2026

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.

Response from Host, Mar 2026

Thank you for your kind words! We’re delighted to hear you enjoyed the company of our crew and found the boat clean and comfortable. We completely understand wanting to see a wider variety of marine life, sometimes it can depend on the day and the spots we visit. We hope you’ll consider joining us again in the future, as each trip can offer something a little different!

Louise_F, Jan 2026

Try not to go on a day a cruise ship is in Port as very busy as spoils the trip. Snorkeling was too busy and a little chaotic for weaker swimmers

Response from Host, Mar 2026

Thank you for sharing your feedback. Cruise ship days can certainly mean there are more visitors enjoying the reef but rest assures, our crew works hard to manage guest numbers and maintain a safe environment in the water so everyone can enjoy their time on the reef. For guests who may feel less confident while snorkeling, our lifeguards are always happy to assist and flotation devices are available to help make the experience more comfortable. There are also a variety of other ways to enjoy the reef, including guided activities and reef viewing options suitable for all abilities. Thank you again for visiting, and we hope to welcome you back for another reef experience in the future.

Didn’t have the opportunity to experience the trip

Sean_P, Jan 2026

We unfortunately had the trip cancelled twice in two days… sadly on the second attempt we received an email at 615 in the morning, to say the trip is on and when we arrived at the check in to be told it was cancelled…

Great experience at GBR!!

Cathy_M, Jan 2026

The staff and crew all knew what they were doing and we can see they have mastered the whole day. They were clear with schedule and instructions. Felt very safe and comfortable

A Great Day Exploring the Barrier Reef

Elaine_M, Dec 2025

Good value in terms of coral reef viewing and catering. Expert ‘education’ talks were very good and safety aspects were expertly enforced for all levels of water activities. Friendly and well trained staff throughout.

Response from Host, Mar 2026

Thank you for your wonderful feedback. We truly appreciate your kind words about our staff and hope to welcome you back for another memorable reef experience soon!

Great experience!

Naimish_T, Dec 2025

Great experience overall. This was our second time trip to Agincput reef with Quicksilver. Didn't had hany problems with over crowding etc. We went on 3rd week of Dec, in 2025. The Quick Silver team provided a great support for a disabled person in our team by providing a wheelchair from office to take it on Catamaran on to the reef. They helped him to embark and disembark the ship and also to move around in Agincourt reef to do the excursions. They also encouraged him to snorkel and helped him to lowering him in water on a motorized chair. So had a very good encouraging experience with great team support.

Response from Host, Mar 2026

Thank you so much for sharing your experience! We’re delighted to hear that our crew could provide excellent support and make your visit enjoyable. At Quicksilver, we pride ourselves on being the most wheelchair-friendly reef tour, ensuring all guests can comfortably explore and enjoy Agincourt Reef with full support every step of the way.

Awesome day with Quicksilver!

DouglasorChristine_B, Dec 2025

Fast & stable catamaran ride out to reef. Good setup for snorkeling & diving for quick water entry-very efficient. Somewhat limited snorkel area -but due to wind & currents probably smart with many beginner snorkelers. Good buffet spread aboard - lots of choice. Nice also that they have the sub experience for elderly or children. Quicksilver also offers a helicopter tour of reef as an add on -others don’t- so more options to do. We chose not to do the helicopter reef tour, but to take the discounted helicopter ride back to Port Douglas in mid afternoon instead when they take the helicopter back for the day. That was a longer ride with awesome reef views and a ride along the Daintree coast with a landing very close to our resort south of Port Douglas. It made our trip even more spectacular - highly recommend!!

Response from Host, Feb 2026

Thank you for your lovely review and recommendation! It’s great to read you made the most of the submersible experience and the helicopter ride back! What a spectacular way to take in the reef and Daintree coast! We really appreciate your recommendation and hope to welcome you back for another memorable adventure soon! 🚁🐠

Excellent crew, very helpful and not too many PA announcements. Food was bountiful and delicious and the trip was delightful.

Response from Host, Feb 2026

Thank you for lovely review, we're glad you enjoyed your trip to the Great Barrier Reef with us!

Great experience

Padmavati_R, Nov 2025

Great experience with this tour - boat was gorgeous, lots of available seating inside and out on the deck. We took the helicopter ride which was worth the expense- stunning views of the reef. Lunch was great and there was a good supply of cookies and snacks during the trip. The crew was friendly and helpful. Want to mention though that the boat was only half full on the day we went so I cannot comment on how things might be if it was full capacity.

Response from Host, Feb 2026

Thank you for your lovely review! We’re so glad you enjoyed the comfort of the vessel, the scenic helicopter flight over the reef, and the food and snacks throughout the day. We appreciate you sharing your experience and hope to welcome you back again soon!

Thank you for your lovely review!

Excellent tour

Maham_C, Nov 2025

It was amazing! My husband and I are not swimmers but wanted to try snorkeling. The lifeguard spent a lot of time getting us comfortable with the equipment and teaching us how to snorkel. After that we spent over an hour snorkeling and a lifeguard was always keeping an eye on us. This is a very well run operation. Started on time and all the other activities ran smoothly. Lunch was fine, tea was decent too. Marine biologist’s presentation was very interesting. Highly recommend!

Response from Host, Feb 2026

Thank you for your review and recommendation for others! We loved that you and your husband felt comfortable enough to give snorkelling a go!

A Must Do!

Aditya_S, Nov 2025

Travelled with family from overseas that were not swimmers. Between the semisubmersible and the ocean helmet walk, there are a few things to do. The cruise ticket includes Lycra suit, flippers, snorkel and mask hire, as well as the semisubmersible. The add-ons that are worth paying include scuba and helicopter ride.

Response from Host, Feb 2026

Thanks for sharing your experience! We’re glad your family enjoyed the semi-submersible, ocean helmet walk, and included gear. The scuba and helicopter add-ons are definitely a great way to make the day even more memorable!

Great experience! They handle couple hundred people pretty well. Safety was of upmost importance. Need to plan ahead on the time that you have on the platform. We enjoyed it immensely.

Response from Host, Feb 2026

Thanks for the great review! We’re glad you felt safe and enjoyed your time on the pontoon. Planning your time there definitely helps make the most of the day. We hope to see you back for another reef adventure soon!
