Great day out, we have done a number of reef tours and can highly recommend these guys. Staff were fantastic, comfortable boat, great food and plenty of it.

An amazing day out with the crew from Quicksilver. The overall package and value is exceptional which I would recommend to everyone. Snorkel sites were perfect with coral, fish, turtles and sharks all sited. Very knowledgeable and fun team who were engaging.

ATravellingSquirrel October 2021

SilverSonic is a very commercialised operation. Very crowded onboard given Covid-19 restrictions. Impossible to maintain 1.5m social distancing whilst onboard. The company still went ahead with self-serve buffet onboard (I was informed that no self-serve buffet onboard when booking). Constant reminder to all passengers to check in with QLD Covid Safe App at the service desk at the Marina but no evidence of any social distancing onboard is shocking. Almost impossible to hear the guide explaining about the reef out at the deck. Reef sites were average with fair amount of bleaching noted. Average amount of marine life despite swimming for about 100m away from the SilverSonic docking site. Final reef site was the most exciting but had the least amount of time to explore. Service: fair Ambience: none Food: plentiful but average in quality Overall experience: Average Would definitely not recommend to anyone looking for a personalised experience. Suitable for those who are just looking for basic transportation out to Agincourt Reef.

The trip itself was great and the dive guides were fantastic. Tammi and Addi really made a nervous diver feel completely comfortable in the water and I'm so grateful for it. There was a snorkel tour too and the staff pointed out things I would have missed on my own (like a lion fish!) The dive sites were beautiful and the equipment was top quality. No leaky masks here! The only downside (which is beyond their control) is that it is a long day of sea sickness if you are prone to motion sickness. This boat is a catamaran AKA a vomit comet. The reef is WELL worth a bit of sea sickness but make sure you take sea sickness pills. Beware when booking as the company have a high minimum number and will cancel on you if they don't meet it, no matter how inconvenient this is for you.

Seriously the best crew and best diving off Port Douglas! This is our second time out with the team and again they didn’t disappoint! The dives sites are unreal! You will see everything you want and more. You know you are in a good boat when you recognise faces from previous trips! We had a triple dive - 3 different dive sites and all are so different. If you want to see the real barrier reef get on board! Whether you dive or snorkel, family or solo, this is the boat for you! Thanks guys for looking after us again and we will see you soon!

LeeA1747 September 2021

The Silversonic outer reef experience took us to Agincourt reef to 3 different dive sites. The boat crew were so friendly and helpful, food great and an awesome day. Thanks to the crew for making the day fantastic

Michelle S September 2021

Awesome day out and oh boy did we pick the best day of the week as the rest of the week was really quite choppy out there on the water. Today was around 10 knots so perfect. I went snorkelling as I have not plucked up the courage as yet to go and dive. We went to 3 Reef sites = 3 Sisters - which was very Reef I have seen up here!, then Phils Reef where me and my friend stumbled upon a huge sharke asleep (we think) on the ocean floor. It was HUGE !!! Soemone said it was probably a Nursing Shark or something. Our last Reef was Turtle Bay which was nothing spectacular but actually my favourate as I go to snorkel with the lovely Simon who was on snorkel duty that day. Food was very tasty. We had breakfast goodies when we boarded then a lovely large buffet (hot and cold) for lunch and later there was even afternoon tea and cake. I had far too many Brownies ha ha ha. Fab day out. My only negative is the lack of comfortable seating upstairs, outside. I would hate to be on this boat when it was full as you really would have to get on first to grab the few seats upstairs!

Beautiful boat, amazing snorkel sites, felt very safe with the lifeguards watching out. Staff were nothing short of fantastic especially Simon (he is hilarious) great food to eat just a wonderful experience and day!! Bucket list ✅

KerriLyn_B July 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.

Warrren_D July 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.

Nicole_M July 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.

Bianca_P June 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.

Shaan B June 2021

For all SCUBA divers and passionate snorkellers this trip is an absolute must. An early departure and fast boat transfer to three different spots along the Agincourt Reef. Staff were friendly, helpful, and informative. The buffet lunch, morning, and afternoon tea was generous. However the real show stopper here is the magnificent beauty of three separate sites along the Great Barrier Reef. This trip has provided our family of five with memories for a lifetime ❤

Jolene_H June 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.

BlairM151 June 2021

This is the second time we have been out on Silversonic to snorkel/dive the Agincourt reef and was once again an awesome experience. Water was warm, fishlife was plentiful and service from the crew and dive instructors was without fault. Definitely recommend using Silversonic if you want to experience the outer Great Barrier Reef.

Sean D June 2021

From start to finish the staff/crew were awsome. Helpful and informative. We were down for snorkelling and an introductory dive. Since making the booking my eldest had some health issues and was declined diving. Which we expected and was the right decision. Then my youngest became sea sick on the way out to the reef so none of us then dived. Our choice. However the crew couldn't do enough to assist and even refunded our dive costs. We then snorkeled at 3 locations, all awsome. Each had there own briefing and what we might see whilst snorkelling. All in all a great day out/adventure and if in Port make the trip top of your list.

We went an Silversonic for a combo dive + snorkel day (I dived, my wife and children snorkelled). The day was excellent. I dived the Agincourt reefs and was delighted to see that the reef was in excellent condition. Our guide (who was excellent) explained that the bleaching event occurred ~10 years ago on the northern part of the reef and the recovery is now such that the reef is very healthy again. I don't remember the exact dive sites, but we dived a bombie (underwater pillar) which was excellent, plus a couple of deeper dives along the edge of the reef. We saw reef sharks on every dive plus smaller treats like clown fish and scorpion fish. The rest of my family loved the snorkelling too. A juvenile reef shark turned up for one snorkel, which made everyone's day. They also saw turtles and tons of smaller fish. Silversonic were very efficient and safe - the food was good, the instructors were great. I would recommend this outfit without hesitation.

Signed up for two intro dives and what a fantastic experience, great crew with a dive guide that really made you feel confident when diving. A great experience that will now see me progress to get my Open water on my next trip up and I can’t wait. The dive sites are so awesome.

GlobeTrotting272946 April 2021

Staff at the check need a good dose of something to make them friendly. Thank god the staff on the Silversonic boat were fantastic. Very knowledgeable and safe practices. Fun and friendly staff on the boat. Food was excellent. Snorkelling sites were great.

Tino_K April 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.

R J April 2021

I intended to snorkel as have not dived in a few years. Immediately, on board, I changed my mind. They were so good to let me dive and incredibly caring as I was nervous. The nerves went straight away and the dives were lovely. The operation to get everyone sorted with equipment and into the water is smooth. The dive instructors were knowledgeable and keen to share about the reef. They even set up the tanks. I took a preventative seasick pill, which was sold on board. No issues. Lunch was the only thing average. Highly recommended!

Amanda_C April 2021

Fantastic experience - awesome reef sites, great crew. Best snorkeling experience I have ever had. You won’t regret it!

Gerard_K April 2021

Your crew were professional friendly and good at their jobs. They helped each other all day as well as us well done..choice of reef sites was varied and perfect. Prescription goggles were a bonus. Magic experience our ages ranged 12 to 70.

AnitaM89 March 2021

This was by far the highlight of our trip - the Silversonic cruise was well staffed, professionally operated and logistically sound. The customer service/friendliness of the staff was excellent and everyone certainly seemed safe and comfortable. The snorkel gear was without fault, food services had a variety, sea sickness tablets available onboard and the onboard marine talk was also great. Only suggestions to Silversonic would be to have an acknowledgment of Country during the tour info/briefing and an info sheet about their dedication to covid safety and cleanliness especially as they’re dealing with face/mouth/body equipment. We highly recommend booking Silversonic or another ‘Quicksilver Group’ tour with in QLD
