Reviews: Cairns Quicksilver Great Barrier Reef cruise [Agincourt Reef/snorkeling boat lunch/optional activities]
Guest User2026-10-08
This trip was absolutely perfect! The Silver Shuttle reached the most beautiful outer reef of the Great Barrier Reef, and I was immediately stunned by the gradient of blue and green coral reefs—it was breathtaking! The 10-minute helicopter ride was incredibly worthwhile and highly recommended! The semi-submarine tour is also highly recommended; the clear underwater world, with its many corals and fish, was truly awe-inspiring. The buffet included in the cruise ticket was delicious, and my friends who went snorkeling also said it was a lot of fun. Thanks to William from Moker Travel for his patient answers and help; we easily found the shuttle to the port at the designated waiting area. It was a perfect day, highly recommended!★

Reviews: Cairns Reef Magic Great Barrier Reef 1-day tour with meals | helicopter/diving/snorkeling
Guest User2026-09-10
The entire Great Barrier Reef trip was very fulfilling, and the crew's service was excellent. Remember to check in for the helicopter as soon as you board; we were among the first to check in. We took the helicopter once we reached the outer reef. The weather wasn't great on the way there, but it cleared up when we took the helicopter, and the colors of the Great Barrier Reef were truly beautiful. The food on board was also quite good (especially the fruit, which was very good; I felt a bit dizzy at the time, and the fruit made me feel much better). There was some free bread on the ship on the way there and back. Before leaving, all the crew members would stand in a row to say goodbye. You definitely have to take a helicopter trip! Unfortunately, I didn't go snorkeling, but my wife and child went into the water. They said they could see fish underwater, and I took picture 2 from the bottom glass of the ship. The helicopter registration staff on the ship spoke Chinese, and there were also other staff who spoke Chinese, which was great. If you want to try other submarine activities, you can check the ship's schedule and arrange your own time accordingly. Just go and queue up when it's time. Each activity is located in a different area on the ship. Also, please note that you should wear a light swimsuit. The rash guard on the boat is necessary if you're going during the summer holidays; it might be a little chilly without one, but it will be just right. There are plenty of rash guards available in different sizes. You don't need to bring your own fins, snorkel, or goggles; there are plenty. I only brought my own goggles and snorkel. If you're concerned about hygiene, you can bring your own snorkel. The lockers on the boat are small, so just grab something convenient to pack your things. Generally, no one uses them; everyone's busy enjoying themselves.★

Reviews: [Price match guarantee: refund triple the difference | Koala holding included] Cairns Sunlover Great Barrier Reef cruise 1-day tour
Guest User2026-02-26
It was a great travel experience. The Great Barrier Reef is absolutely beautiful, and the whole trip was smooth and enjoyable. The buffet was delicious, and the helicopter ride was fantastic. The only downside is that seasickness is quite common when going out to sea, so it's best to bring seasickness medication.★

Reviews: Cairns Green Island Great Barrier Reef Big Cat half-day tour snorkeling/glass bottom boat
Guest User2026-10-27
I signed my father up for the trip. He's 63 and traveling alone, and he was completely satisfied with the itinerary. He had a perfect snorkeling experience, truly felt the beauty of Green Island, and the crew took excellent care of him, even checking on his physical condition before the snorkeling session.★

Reviews: Cairns Great Barrier Reef + Fitzroy Island 1-day tour
Guest User2026-10-27
I traveled to Cairns with my father, and we booked different itineraries on the same day. He didn't want to walk, so he went to Green Island on the Big Cat, while I chose Emerald Island because I wanted to experience some rainforest and kayaking. It was definitely worth the trip. Emerald Island has a very diverse landscape, from the Jellyfish Sea to the beach to the rainforest. Overall, I was very satisfied with the trip!
