Explore the outer reaches of the Great Barrier Reef with this full-day adventure to Agincourt Reef, which sits at the edge of the Continental Shelf. After pickup from your Port Douglas hotel, board a comfortable 95-foot (29-meter) catamaran and settle in among the inside cabin seats or sun decks for the scenic ride out to the reef. 

Throughout the day, visit three renowned dive sites that the cruise has exclusive access to, and customize your adventure with different options for exploring the reef. If you prefer to stay close to the surface, splash into the clear waters with provided snorkeling equipment and either snorkel on your own or join a guided tour. Or, go even deeper with a scuba experience. Beginning divers can try an introductory dive, and those with scuba certification can embark on up to three certified dives. 

No matter what you choose, you’ll get an up-close perspective on the spectacular ribbon reef teaming with an array of marine life such as schools of tropical fish, small reef sharks, massive coral formations and giant clams weighing up to 440 pounds (200 kg)!

When you come to the surface, recharge with a delicious buffet lunch on board, and break for morning and afternoon tea. Grab a drink from the fully licensed bar if you’d like something stronger (own expense), and stay comfortable with facilities including restrooms and freshwater showers. After approximately 5 hours at the reef, relax and soak up views of the Coral Sea on the return trip to Port Douglas. 

Note: Book early to secure your spot, and enjoy a flexible reservations policy that allows you to change the date of your tour at no additional charge once you arrive in Port Douglas.

The crew were lovely and professional. They were always around to help out and made the experience great.
Value for money for all ages.

An Excellent Captain & his crew. A great day out with a well laid designed boat & snorkelling platform to see the tropical north reef in it’s stunning variations of coloured fish and corals. The catered lunch was a tropical variety to match. The Helicopter flight allowed an excellent platform to view the reef in it’s best colours. Looking forward to doing more next time. Well done! Cheers

Had a friendly visitor while scuba diving!
, Apr 2022
We were blessed with a beautiful sunny and not too hot day with crystal clear water. The staff were wonderful, very friendly and approachable. It was our first time doing the intro scuba dive. Very well worth it and we even got to see a turtle that we had a photo with. That was our highlight on top of seeing the beautiful reef and sealife. I thoroughly recommend this adventure as one to put on your to do list if you're up this way!!!

Silversonic - a great days snorkeling
, Feb 2022
Had an amazing day with the Silversonic team. The skipper know exactly where to go for the best snorkelling conditions and fish to see and the guides were very informative about what to look for. Nice lunch, helpful and friendly team
Best experience ever!
, Dec 2021
My partner and I had the most amazing experience doing the outer reef tour. As a first time snorkeller in the middle of the ocean, I was hesitant, but the crew made the experience easy by giving you all equipment to make you feel comfortable. By the end of the day my life jacket was off and I had no noodle to hold on to. Best experience ever would do it again!! The first reef was the best one!
Silversonic dive trip Port Douglas
, Nov 2021
The staff were excellent, it shows they enjoy their job, very friendly and helpful. The dive and snorkel areas we went to were great but wished we saw a bit more variety but that’s nature. The fish life was in abundance. Food supplied was excellent.
, Jul 2021
What a wonderful crew. So informative and friendly. They took the time to make sure I was feeling comfortable in the water and made sure I saw some amazing sites. The coral and fish were stunning. The Reef is looking amazing now and well recovered from what we were told. The 3 reefs we were taken to were amazing...each one different from the other. The food was one of the best you get on any tour, plentiful. The vessel is well kept and clean. Could not fault anything at all. Will definitely recommend to others this company and tour and would do it again in a heart beat.

Was ok
, Jul 2021
Crew and food was good. 1 out of 3 of the dive sites was worthwhile, the other two were overcrowded and visibility was average. Can’t blame the crew for that.
Great experience
, Jul 2021
I did two intro dives. My instructor Simon did a wonderful job ensuring you felt comfortable with the whole process and was a great guide under the water always on the look out for cool marine life. I highly recommend.
Incredible service and so many fish!!
, Jun 2021
My husband, 3 kids snd myself had an incredible time on the reef with silversonic. This is the second time I have been with them and both times the staff went over and above what is expected of them. Lots of great food available most of the day. Both times I have been I saw at least 20 times more fish than I ever. saw on previous reef trips with other companies (to the inner reef). I can’t recommend them highly enough.
Great snorkelling spots
, Jun 2021
The Agincourt reef spots were fantastic! Great snorkelling and a lot of time on the reef which was great! All staff members were relatively friendly, Tami was our favourite, she was so lovely, Jamie was quite unpleasant and she really just did not want to be there. Other than that our day was good.
Great vibe
, Apr 2021
The team was fun and professional, they took a lot of care for everyone and the catering was yummy. I lived the trip, the extensive knowledge of the guided tours and the vibe on the very clean catamaran sailing boat - all finishing with a romantic sunset in a dramatic sky. Highly recommended - I’ll do it again.
Excellent experience!!
, Apr 2021
Fantastic experience - awesome reef sites, great crew. Best snorkeling experience I have ever had. You won’t regret it!
