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.

Lots of ways to see the reef :-) Large pontoon catered really well for the 300 people. Never had to wait for an activity.
Would 100% recommend
, Jun 2022
The staff were amazing, facilities at the reef were well organised and the food was delicious! Would definitely do again!
Making it easier for the ‘not so nimble’
, Jun 2022
I have difficulty walking & a number of health issues. Every member of the crew is attentive and helpful. It’s a large and intimidating ship but from the Captain through to the crew everyone is friendly welcoming and safety is a focus. The pontoon is larger than any one I have seen, it’s a structure out at the reef. It even has a ‘lift’ to lower someone like me into the water. It was great, but slightly out of my comfort zone to be immersed into the reef & see some coral and fish. I think it’s better to go twice in order to prepare for the experience.
Fantastic experience
, Jun 2022
Fantastic day , great experience. Very helpful crew . Very informative. Thank you for a great day ..
Overwhelming experience -LOVED IT
, Jun 2022
Seeing the Great Barrier Reef was amazing! Let alone the way quicksilver showed us. The staff were so nice and welcoming! So easy to talk to if you had a question or just to have a chat. The activities for the day were so amazing and fun and they made sure you knew of the schedules for the day so you didn’t miss out on anything. Would definitely recommend this to anyone!!
Great day on the reef

Very well organised - everything we needed was available and staff were friendly and helpful. Very sad to see the reef in decline though.
Amazing Tour, Amazing Staff & an outstanding Great Barrier Reef!
, May 2022
The whole experience was amazing. The crew were all lovely & everyone played an important role to the tour which clearly showed. We would highly recommend doing the Marine Biologist tour. We had Hayley as our guide, her knowledge & enthusiasm towards her work & the reef made it feel a whole lot more special.
Great day out- an experience to remember!
, Apr 2022
My family and I went on the quicksilver cruise and it was unreal. Bumpy conditions on the way out- the crew were very attentive to my child who was sick. We were unaware of professional photos that going to be taken which an added bonus- this included underwater photos while snorkelling. It was a great day out and really topped off our holiday. Will definitely go on this cruise again!!
Good and fun
, Apr 2022
Staffs are very friendly, food are fresh. Everything is good except the toilet. Overall we had a good time with quick silver.
Wonderful Day on The Reef
, Apr 2022
Amazing trip - informative presentation from a marine biologist on the trip out, so much to see and do whilst on the reef. Safe and fun for all swimming abilities. What a wonderful day out
, Mar 2022
We had a great time the lunch was nice it was a great experience really enjoyed the sub thanks for the good day
Not much to see in the snorkeling site
, Feb 2022
The snorkeling site has not much to see but it's exciting for beginners though. Not sure if they can move the pontoon elsewhere. Photo op distructs your attention maybe because there's less to see. It appears great barrier reef is overrated? The food was ok except the chicken which was hard as rock and cold. Interestingly the guy who handout the lycra suit knows the size of every guest. Contrary to our reviews we were lucky that it wasn't crowded and the catamaran wasn't packed.

Great fun family trip for adult kids
, Jul 2021
Diving was great. We don’t have a ticket but the instructor was fantastic. The snorkelling was also great - so much coral and fish varieties.
Do it!
, May 2021
Very smooth operation. Staff were great also. Despite the poor weather and visibility it was a great day out. The reef didn't disappoint! also loved the semi submersible. The food was fabulous as well.
Must do this when in cairns/port Douglas
, Jan 2021
This is a must do when visiting port Douglas! All of the staff where super friendly and approachable. We went during the stinger season but not to worry, stinger suits are provided for free. Very good value! We where the talk of the tour getting engaged 500feet above the beautiful reef on their helicopter!

Tour good, viator wrong
, Oct 2020
The tour was good but felt slightly rushed. Viators information by email was incorrect, it says departs 10.30 when infant it departs 10 and needs you to board 9.30 so if we hadn't of been there early for a coffee we would have missed the tour!!!
Don't miss this one!
, Jan 2020
A fantastic excursion. Their great barrier reef platform was impressive. Snorkeling there was superb. The submersible boat trip was really neat.

Way too crowded, not enough seats on the boat which means standing for one and a half hours each way. Food offerings not great.Coral viewing not very good most of the coral is dead.
