Full description

Climb aboard a Quicksilver catamaran for a full-day cruise to Australia’s renowned Agincourt Reef, a jewel-like ribbon reef on the edge of the Continental Shelf.

Showcasing unsurpassed coral formations, colorful marine life and exceptional underwater visibility, you can snorkel or view the sights from the comfort of a semi-submersible. The Quicksilver's stylish wave-piercing catamaran transports you in air-conditioned comfort. From the spacious activity platform, moored in a protected lagoon, enjoy the widest range of activities for swimmers and non-swimmers alike. A friendly and attentive crew, including professional marine biologists, are on hand to ensure you gain the most from your day. Snorkel among the coral gardens, or stay dry and explore the reef from the comfort of a semi-submersible.

Enjoy an informative reef commentary and see the reef from an underwater observatory. Add on exciting optional activities for a complete adventure.

This is a well organised trip out to the reef so people can do snorkelling safely and in a very professional manner. But if you would rather a more low-key experience with less people and if you are confident in the water maybe this is not the one for you.

Snorkeling in a safe environment made the trip go quite well. It was very comforting to know the staff was alert and watching over us the entire trip. The coral reef & surrounds are an unknown place to most people but the staff told us how to be safe & enjoy the reef.

Brilliant range of activities for varied ability levels. The semi submersible was wonderful for less mobile and mobile individuals and the talk by the South African man was informative and entertaining. All the staff were outstanding and gave me the confidence to snorkle and swim on the reef while feeling safe. Amazing experience. The talks by the staff on the catamaran to the reef were brilliant. Lunch healthy and delicious. A superb day ending in beautiful views on trip back to Port Douglas.
