An average outing

Seeing the coral and fish from the glass bottom boat was great. Green Island is not much of a place. The food outlets are a bit grungy. So we were glad to finally make the return journey back to Cairns. I would not do this again.

A great ride to a great experience

Note that you have to go to the tour office to get the actual tickets ahead of the boat time. The boat was fast and comfortable. The staff was very friendly. Green island was great and had super snorkeling. There are restaurants and food options available. They had public shower area to rinse off. Bathrooms on island.

Very short experience.

I chose to go on the flat bottom boat. It lasted only half an hour and the rest of the time I spent walking on the forest boardwalk. I think the tour is better value for those who snorkel.

Operator response

Thank you for taking the time to share your feedback. We’re sorry to hear you felt the experience offered limited value. The glass bottom boat tour is designed as a guided reef viewing experience, typically around 30 minutes, allowing guests to view key coral and marine highlights with commentary from the crew. Many guests choose to combine this with snorkelling or time on the island’s rainforest boardwalk to make the most of their visit. We do appreciate that guests have different expectations and preferences depending on how they choose to spend their time on Green Island. For those who snorkel, there is certainly more time spent in the water; however, the glass bottom boat and island walks are designed to provide a more relaxed, above-water way to experience the reef environment. Thank you again for your feedback—it is appreciated and will be shared with our team as we continue to review how we present our inclusions and guest experience.

Great trip

Very easy check in at Cairns terminal. Boat ride and crew was great, even getting a cuppa on board before departure. We had the glass bottom boat included in our ticket which I highly recommend and then we paid to hire a snorkel and goggles to see some of the reef ourself, another activity I highly recommend . Lots of food variety on the island for lunch and showers and toilets . We did the 6 hour, which we found was plenty for us, but would be easy to chill on the island all day . Loved it .

Operator response

Thank you for your wonderful review! We’re delighted to hear you had such a great day with us, from the easy check-in at the Cairns terminal through to enjoying a cuppa onboard and a smooth journey to the island. Thank you again for choosing to travel with us, we hope to welcome you back for another “loved it” experience in the future!

Tour guide a-hole!

Very unhappy as my son had to wee in his pants after asking for 15 - 20 minutes to have a wee out the back as we were drifting along. No apologies or anything from the guide only simpethy from other members on the tour.

Operator response

Thank you for taking the time to share your feedback. We are very sorry to hear about your son’s experience and the distress this caused. For your reassurance, there are several toilets available on board our vessels, and a wait of 15 minutes on the outward journey is not common or expected under normal operating conditions. We understand how upsetting this would have been, particularly in this situation, and regret that clearer assistance was not provided at the time. Your comments have been passed on to our operations team for review and follow-up with the staff involved. Thank you again for bringing this to our attention.

The tour operator decided...

The tour operator decided to add surcharge of $4AUD due to rising gas when I booked the tour 3 months ago. All other tours decided not to add surcharge as it's part of doing business. It is especially true when the cruise has capacity of 300+ so it's easier to hedge costs. When the gas prices come down it's not like they will refund $4 instead

Operator response

Thank you for your feedback. We understand your concerns regarding the fuel surcharge and appreciate you taking the time to share your perspective. As is common within the marine tourism industry, fuel surcharges may be applied in response to significant and sustained changes in operating costs, including fuel prices, which can fluctuate between the time of booking and the date of travel. We do our best to keep any additional charges to a minimum and remain transparent with guests when these are introduced. Your comments regarding pricing fairness and communication are noted and will be shared with our management team for review. We appreciate you choosing to travel with us and hope there were still enjoyable aspects of your time on the reef.

day trip out

Good operators, friendly knowledgeable staff. Easy check in, we stayed for 3 hours on island, was enough time for us. Had a snorkel, and a glass bottom boat ride. Had to pay extra to do both, but I was aware of that.

Operator response

We’re really pleased to hear you found our crew friendly, knowledgeable, and the check-in process smooth, and that you were able to enjoy both snorkelling and the glass bottom boat during your time on the island. Thanks again for choosing to visit, we hope to welcome you back again in the future for another great day on the reef.
