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.

Snorkeling off pontoon was safe and fun, we got to see an amazing variety of beautiful fish and even a large green turtle, there was lots of options on how to spend your day and loved the glass bottomed sub, food was good and staff were lovely. Great day out on the reef 🪸

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.
