Greta experience. Highly recommend. - We just did the half day with the semi submersible & wow. What a great trip we had. Saw lots of reef wildlife in the semi submersible. The staff were helpful, friendly and experienced - just what you need on a trip like this. We were also blessed with fabulous weather and nice calm waters so that was a win too!

Best view under the sea - Highly recommended for those unable to snorkel or scuba dive to get closeup view of coral, fish and turtles with narration

Green Island Half Day - We had a great time on this half-day trip. The snorkelling was easy and the water was clear. We saw a reef shark, a stingray, and heaps of colourful fish. The boat was comfortable and the crew were friendly. Everything ran smoothly and we loved the whole experience. Highly recommend.

Green island excursions - Nice boat ride to island. Beautiful place. Glass bottom boat ride good, saw lots of fish, turtles etc. but narration bad—sound system poor and you unable to understand narrator.

Overall , great trip . A... - Overall , great trip . A little rushed because the glass bottom boat was 2.15 and we arrived at 1.50 so by the time we went to shore and settled , we were off again. Snorkelling was nice , but short of time .

Good experience over all - Good trip although not much time to explore the island. I should have booked the full day! Sea was rough and i forgot my motion sickness meds, so felt a bit poorly. The sub was really swaying which made it worse so highly recommend something for sea sickness!! Did spoil it a bit but was my own fault! Island is beautiful

Beautiful views of the Great Barrier Reef. - Green Island is very tropical. The boardwalk is definitely worthwhile. A big chunk of the half day consists of the return trip to the island. The half-hour glass-bottomed boat trip is short but spectacular. Overall, a very enjoyable trip.

Quick boat beautiful island - The island was beautiful, the boat was nice and quick to get there. We were even lucky enough to see a turtle! However everyone vomitying were asked to go outside to the back, unfortunately the family right beside us didn’t listen and just allowed their 2 kids to vomit right near us. Not the crews fault at all but it really ruined it for us as the smell was horrendous and made us feel sick.
