★★★★★Viator review
An excellent experience
Louise_W, October 2026
A really well organised trip for both divers and snorkellers. We went to three different sites and saw thousands of fish, including a reef shark, and a turtle. The staff were friendly and helpful, the food plentiful, and the whole experience was just excellent.
★★★★★Tripadvisor review
So much fun and had no idea I would love it so much
535glennm, October 2026
1st time scuba. Had no idea how good it would be. 2nd dive was snorkel - scuba was so much better especially in choppy water. The divemaster was awesome making everyone feel comfortable and of course safe. Had no idea how good this was until later in my trip, tried to do a similar experience elsewhere that never compared to this one.

1st time diving on Great Barrier Reef
Neilandsharron, September 2026
I think this trip was a bit expensive but the reef we dived on was over an hour away (take your sea sickness tabs) hot drinks can only be served when boat is stationary so grab one as soon as you get on board. Safety brief and dive guides were great, as was the lunch. Eat as much as you can as any left overs will be binned. Diving was ok but a lit of it was above 12m. All crew are very friendly and helpfull. Gets a bit crowded on aftdeck with all the snorkellers but they try to stagger them with the divers. GBR was a bucket list tick, but i still think the red sea is better. They take lots of photos but a $36 aus each I thought they were a bit expensive. Long trip 7:30 check in returned about 16:30

For more experienced swimmers
Claire_T, September 2026
If winds are over 10 knots it’s hard to swim on the reef. At least it was for me, an average swimmer. Didn’t get to see much of reef due to high waves and fear of being swept out. Crew was competent. Make sure to ask for help when you need it. Stick to tour with pontoon stop unless you are a very good swimmer.
Response from the operator · Emily V
Thank you for sharing your feedback. We’re pleased to hear you found our crew competent and appreciate your comments about the conditions. Wind and sea conditions can make snorkelling slightly challenging, particularly for less confident swimmers, and safety is always our priority. Our crew are there to assist, so we encourage guests to ask for help whenever needed. We’re glad you enjoyed the experience despite the conditions.

Incredible day on the reef
Stuart141, September 2026
This was just the best day- really well organised from start to finish professional and felt really safe. I was snorkelling and absolutely loved it, the marine knowledge of the young guide was very good- you need to pay her more 😉 There were so many fish and coral, even saw a reef shark, the Maori Ressa was an interesting fish. Food was great, and the Silversonic got us there really quick and smooth. Would definitely recommend
Response from the operator · Emily V
