Fantastic 5.0
Great day tour at the Reef, we got to stop at 2 diving spots and my package also includes 1 helicopter flight. The operator also has a photographer, who helped you took underwater photos which you can purchased later (though it is quite pricey at $20/pic). Lunch is basic (steak, prawns, grilled fish, salad & pasta) but delicious, and the prawns were very fresh. What I wish could have been better is the helicopter flight announcement - it would have been better if they announced my turn roughly 10-15 mins before the flight took off, so I'd have enough time to change to normal clothes (I was snorkelling right before that). Also I believe if passengers are given at least 30 mins before departure to take motion sickness pills, it will work better. Some passengers on my trip took the pill but still got sick, maybe bcoz the pill did not have enough time to take effect (you gotta take it after breakfast, at least 30 mins before departure).

Since I was a bit nervous about swimming, I opted for the glass-bottom boat and snorkeling package! The glass-bottom boat was amazing; just looking down, I could see beautiful fish and sea turtles, which was truly breathtaking. For snorkeling, I paid an additional AUD 12 to rent a life vest! Just a short distance away, there were schools of colorful fish, and swimming among them myself was a completely different experience. (The fish themselves were actually clearer to see from the glass-bottom boat!) Coin lockers, the souvenir shop, and restaurants all accepted credit card payments!

I was worried about check-in and other procedures since I don't speak English, but I'm so grateful that there were many Japanese staff members who provided support. We were also blessed with good weather, and it truly became an unforgettable memory!

Excellent experience! Thr Great Barrier Reef is definitely worth going! Sunlovers boat was really nice compared to other boats. The guides to the SeaWalker and the Scuber Diving were excellent. We also had the best snorkeling experience !

Great day tour to the Daintree, but I do feel like the itinerary is a bit rush. We got too little time stopping at the Mossman River Creek & Cape Tribulation (I really wished we had more time in those places). On the other hand, I really love the welcome to country ceremony & introduction to local indigenous culture - really eye opening experience. The river cruise and walk thru the rainforest also came with clear introduction & excellent guide.

Great 4.0
The boat transfers were smooth. We had 2.5 hours on Fitzroy Island and 3.5 hours on Green Island, though I’d definitely prefer more time on Fitzroy and less on Green. Both islands are lovely for swimming and relaxing, but not great for snorkelling. The glass bottom boat was the biggest letdown — the glass was dirty and mossy, making visibility poor.

They had a young, vibrant and helpful team to guide you in snorkelling. You just have to be at least fit and healthy to attend. The experience was awesome and the crew and team really takes good care of you. Swimmer or non-swimmers will probably be better to get a float during the snorkelling experience. For those who haven snorkel before, the sea water is really salty but the underwater coral views are amazing!!! Maximum pax to join will be around 30 to max 40. Snacks and sea sick pills are available on board and you can pay them when you alight at the end of the trip. Super highly recommended to join this experience.
