Quicksilver Reef Pontoon
The Platform at Agincourt Reef Site: Floating like an island in a coral sea the platforms have tables for you to enjoy lunch, undercover seating, fresh water showers and change rooms to allow you to enjoy your day. There is also a water powered lift to allow easy access for all passengers.

Semi-Submersible Coral Viewing
If you would like to stay dry, then you can explore the stunning reef from the comfort of a Quicksilver sub. The semi submersibles cruise slowly through the colourful coral gardens giving passengers the opportunity to experience a snorkelers-eye view of the marine life.  The semi-sub experience takes approximately 20 minutes and includes an informed commentary on the marine life observed during the journey and an overview of the wonders of the Great Barrier Reef. 

Underwater Observatory
You can also see the coral and watch the fish feeding from Quicksilver's unique viewing platform and underwater observatory located directly in front of the platform. From here, you can also view "first time" divers taking part in introductory dives and snorkelers. 

Snorkelling is one of the best ways to view the incredible underwater world of the Great Barrier Reef, and Quicksilver's friendly staff are on hand to show you how. On your way out to Agincourt Reef you can view an instructional video on how to snorkel to teach you the right techniques.

Agincourt Ribbon Reefs
The very edge of the Great Barrier Reef.  Here, special reefs known as 'ribbons' run parallel to the Continental Shelf.  Adjacent to the Coral Sea trench, these ribbon reefs are recognised as the most pristine eco-systems in the reef's environment.  Clear water provides the best possible underwater visibility, encourages rich coral growth and supports spectacular marine life.  As the region's outer reef pioneer, this is the best location available to view nature's finest.

The whole trip was very good especially the staff onboard the boat. We would also recommend you go with the marine biologist for the snorkeling portion of the trip as it was well worth the extra cost.

We cannot wait till next time
