Set out on a full-day adventure to the Agincourt Reef, one of the most pristine and spectacular parts of the Outer Great Barrier Reef. Cruise in air-conditioned comfort aboard Quicksilver’s modern wave-piercing catamaran and arrive at a spacious activity platform moored in a sheltered lagoon.
From here, you’ll have the widest choice of reef activities, perfect for both swimmers and non-swimmers. Snorkel through coral gardens teeming with tropical fish, or stay dry and view the reef from a semi-submersible vessel, the underwater observatory, or through engaging reef commentary from marine biologists.
The friendly crew and onboard experts are available to guide and enrich your reef experience. For even more adventure, upgrade with optional activities such as introductory or certified scuba diving, helmet diving, marine biologist–led snorkel tours, or a scenic helicopter flight offering breathtaking aerial views of the reef.
Whether you choose to dive in or admire from above, this Agincourt Reef tour offers the ultimate Great Barrier Reef experience from Cairns or Port Douglas.

We were a family aged from 14 to 81. There were activities we could all enjoy, from snorkelling (which was very easy and well-supported - no experience necessary) to a fascinating trip on a ‘semi-submersible’ (a sort of glass bottomed boat) and an ‘underwater observatory’ (which was a bit like a glass bottomed boat that doesn’t move). All offered excellent viewing of the varied corals and fish life of the reef. The boat was large and comfortable, and the whole thing was very well run by well-informed staff.
Check-in and collect your boarding pass at 9:00 AM from the Quicksilver Reservations counter inside the Crystalbrook Superyacht Marina.

Know before you go
Not allowed
Absolutely. You can see the reef without entering the water by joining the included semi-submersible tour or visiting the underwater observatory. Both offer close-up views of the coral and marine life, with commentary during the semi-submersible journey. If you would like to try the water, buoyancy vests are available and the snorkelling platform provides easy access at water level.
Yes. The reef platform makes it easy for first-time and less-confident snorkellers to get started. Snorkelling equipment, instruction, qualified supervision and buoyancy vests are included. Bench seating at water level lets you put on your mask and fins before entering, while flotation aids provide extra support in the water.
Yes. The spacious catamaran and reef platform are pram-friendly, with ramped areas and plenty of room for families. Child-sized masks, snorkels, fins and lycra suits are available, while the semi-submersible and underwater observatory give children another way to discover the reef. Children must remain under responsible adult supervision throughout the day.
The platform has plenty of space to settle in between activities, with more than two-thirds of the area shaded. Facilities include undercover tables and seating, change rooms, freshwater showers, a buffet area and a sundeck. Toilets and air-conditioned seating are available aboard the catamaran alongside the platform.
Free prescription snorkelling masks are available in strengths from -2 to -8. Ask the safety supervisors at the snorkelling platform when collecting your equipment. Regular glasses cannot be worn underneath a snorkelling mask, and contact lenses are not recommended because water may enter the mask.
The wave-piercing catamaran is designed to provide a comfortable journey to the Outer Reef, but the crossing takes around 90 minutes each way and sea conditions can vary. If you are prone to motion sickness, it is worth preparing before the boat leaves the marina. Motion-sickness medication is available to purchase on board, and complimentary ginger tablets are also offered.
The main catamarans and reef platform provide ramp access, and the primary vessels have an accessible toilet. Access to the semi-submersible, underwater observatory and standard snorkelling platforms requires stairs. A water-access lift is available at the Agincourt 3 platform for guests weighing up to 90 kilograms, although the vessel and platform used can occasionally change. After booking, please contact us with any mobility requirements.
The cruise were amazing. The staff were superb from start to finish! This completely exceeded our expectations.

Big shout out to all the staff -very caring, considerate. 100% recommend to everyone!
Fabulous day out, very well organised and friendly staff.

Small group, friendly staff, great snorkeling paar with Great Barrier Reef.
This was by far the best trip we did during our 3 week holiday to Australia. Everything about this tour was top notch. The ship, the staff, the lunch, equipment and the destination was incredible. For once, lunch during a trip was enjoyable and plentiful. The equipment too was far superior compared to the two other snorkelling trips we’re been on. There was activities for non swimmers too
