There is no better feeling than the breeze in your hair and wind in your sails as you relax and encounter breaching whales, cheeky turtles, dashing dolphins riding the bow and shy elusive sea snakes- all this before you even get to your first scuba dive site.


Such an incredible experience aboard Coral Sea Dreaming. Great positive, witty crew that are willing to help in any way they can, all with extensive knowledge on diving. Since the trips are limited to 12 people, its a very intimate experience and the overnight stay means there's plenty of time to settle in and make the boat feel like home. It's a great value for anyone wanting to experience the great barrier reef on a more personal level. It felt more like a few close friends taking us out on their boat than a cash grabbing, big name company. Relaxed atmosphere with a very professional team!!

Love, love, loved it, such a great experience, amazing crew and passengers. This would have to be the best boat I have been on in Cairns. Can't wait to hopefully come out another time because It's had so much fun! Thanks again Coral Sea Dreaming you guys are awesome.

We sailed, we laughed, we dived! A great two days onboard Coral Sea Dreaming

We are just back from the two day one night sailing and diving trip on Coral Sea Dreaming. We chose these guys as they were smaller than many of the much bigger operators out of Cairns and hoping for more personal and less hectic approach with smaller diving numbers. We were not disappointed. The maximum allowed on the boat is 12 guests and 3 crew. It made for a much more intimate trip which allowed us to get to know everyone on the boat really well by the end.

The crew were all brilliant and looked after us really well. My friend and I went specifically to dive and the biggest group we dived with was four. Morgan the dive master was attentive and patient as there were different levels of competency but made each dive a great experience for everyone. Thanks guys for a cracking two days. Highly highly recommend Coral Sea Dreaming!

We had an amazing time doing the 2 day/1 night sailing trip with Coral Sea! The crew was amazing and fun. The dive/snorkel sites were fantastic. I even did my first night dive which was a wonder in itself. We saw turtles, rays, sharks, and fish galore.

The Great Barrier Reef is a Wonder for a reason and Coral Sea made our time out there amazing. The food was good and the boat was cool. They supply you with everything you need.

Even if you don’t dive, you will see a lot snorkeling. However, if you are interest in diving but haven’t been certified, don’t worry, they take first-timers a lot and make it very comfortable.

This was such an amazing trip. The group (Jan, Joris, and Julien) was really knowledgeable and made our time exceptional. We did 6 dives total. Including 1 night dive. We saw sting rays, a shark, and the reefs were beautiful. I highly recommend it to anyone who wants to have a nice diving experience without feeling pressured to rush. It was my best experience diving thus far

Marine via TripAdvisor

My sister and I had the best time on Coral Sea Dreaming!! the crew was super friendly and kind, skipper and his wife (and adorable baby) were absolutely wonderful. We loved having a smaller boat as it allowed us more one-on-one dives, all around an incredible experience!!!!

We had a ball, beautiful boat, great crew and the majestic Barrier Reef.
This trip is a great alternative to the day reef trips on offer. You get 2 days sailing plus 5 different sites on which to dive or snorkel. The crew were very safety focused whilst being fun and helpful. Food was fresh, tasty and plentiful which is fabulous because this experience will make you hungry.

If you want more than one site/day to experience the reef then do the numbers; 2 day trips to the reef plus 1 night in a hotel will cost about the same if not more than CSD’s overnight reef trip. So just do it.

Thank you Jens, Alex and Timmy.

I went on the overnight Coral Sea Dreaming trip Dec 3-4, 2019. I had an amazing time and highly recommend it to anyone who wants a personal dive experience. We had 10 passengers (from America, New Zealand, and Germany; family with teens and young adults, couples and solo travelers) and 3 crew (Christian, Mike, and Carla) who took care of everything from teaching us how to dive to preparing our meals. It felt like we were traveling on a boat that belonged to a good friend, everything was so chill and easy. They like to warn you this isn't a luxury cruise line, and it doesn't zoom you out to the reef and back as quickly as possible in a day. But honestly I felt so comfortable despite the tiny bunk beds and bathrooms. It was air conditioned downstairs and everyone slept really well with the rocking. The diving itself was unforgettable. We had 2 certified divers, 4 intro divers, and 4 snorklers, and everyone had plenty of time in the water. I nearly chickened out of diving but Mike the instructor gave me a pep talk and I was so glad I did it! We saw so much at the dive sites - giant turtles, colorful parrotfish, sharks, clams, clownfish, etc. A few people also braved the night dive. I really loved this trip! True highlight of my time in Australia and a bucket list life experience!

Tara Klein - via Trip AdvisorIncredible experience - highlight of my time in Australia

After spending a load of time reviewing the dive companies in Cairns, I settled on Coral Sea Dreaming because of it's intimate nature. I was not disappointed as the 11 passengers and 3 crew on the boat made for a fun experience and I didn't feel like I was lost among a packed ship for one of the larger companies. It also was 2 days long and fit our compressed timeline in Cairns well.

Each of my certified dives was guided (albeit in a group of 6) so I didn't have to worry about finding my way around. Everyone was capable so we didn't have any trouble navigating the reefs. My GF was even introduced to diving using the introductory package and ended up taking all the introductory dives AND the night dive which this ship offers to new divers. It takes a bit of guts to go diving as an intro, but they made it easy.

The food was tasty (thanks Leo), the laughs were great (thanks Mike), and I learned so much about diving and the reef (thanks Christian). That said, you need to be prepared for the experience. This isn't a resort. The bathrooms are small. The boat rocks when you sleep. You might get seasick (so take a motion sickness pill when you get on and in the morning)..... BUT this is an authentic experience to get out on the reef and truly feel connected to it. Thanks for the great time guys!

Me and 4 friends booked this trip on 2 perfect weather days which meant we had the best experience we could of asked for! On the way there we saw dolphins and whales and the diving itself was top tier! Highlight was night dive then checking out the stars afterward as it was so clear you could see the whole Milky Way. Thanks coral sea dreaming we will be back!

Jake - via Trip AdvisorRadical Trip

Best trip ever! All crew are extremely nice, foods are super delicious, and no sea sick! We saw lots of wildlife, beautiful reefs, stunning sunset and sunrise. Never forget the dolphins they swam with our boat. 100 % recommended for everyone!!

Christian - via Trip AdvisorAmazing Times

We had a great experience on the Coral sea dreaming sail boat and with the crew. Our trip was for 2 days and 1 night and included meals and snacks and snorkel gear and wetsuits and dive gear. All the equipment was in great condition so there was no hesitation using it. Crew Alex and Jo were amazing in the way in which they guided us and helped us from beginners to the experienced whilst Captain Jan did very competent captain things. And the 3 of them took turns in making us delicious meals with plenty of fresh fruit and veg. I'm really glad we chose these guys to do the GBR with and if we go out again I'd definitely choose this group. Thanks Jan, Alex and Jo for a great trip and some pretty cool memories

Kelly H - via Google

Unforgettable experience. Capitan Jan smoothly delivered the vessel to the clearest sweetspots of the coral reef. Crew men Timmy and Alex were experienced sailors and superb diving instructors. The sea life in the reef was unbelievable. Whales, sharks, mantarays, turtles barracudas, cuttlefish and countless species colorful fish and corals. I will definetly come back for more next season. Must not miss.

We are locals and boy-oh-boy was Coral Sea Dreaming a great find! I booked for hubby's b'day, and the whole family (2 teens) loved the overnight trip. From my first initial email query to stepping off the boat after a great trip we were totally looked after (including great local rates). The staff and crew were super friendly, helpful, professional, knowledgeable and absolute fun. It was our first time scuba diving and it's safe to say won't be our last. The highlight for all being the magical night dive. (bucket list must). Each of the 3 different locations we visited on the reef were stunning. Highly recommend. Well done crew.

Allison NMust do for locals & visitors! Night dive is magical.

"What a treat, there is a thing ‘crying under water out of pure joy’! TV cannot portray the reality, the feelings, the emotion. SCUBA and snorkel in the worlds best natural aquarium, so much to see, an overwhelming treat for the sense. The Skipper and crew are more than accomodating, beautiful energy, wonderful guides. Stop dreaming it and do it. Help local small businesses get back on their feet post the covid craziness. I wish Coral Sea Dreaming every success. So much gratitude Tania 🧜‍♀️"

Tania McMillan"Lift your soul"

The overnight trip to the Great Barrier Reefs with Coral Sea Dreaming was absolutely perfect. Everything went smoothly right from the start. The crew was knowledgeable, and the atmosphere was warm and friendly the whole trip. The trip was intimate and personal, and the diving/snorkelling destinations were stunning.

Phil, our skipper, is a proper old school sea dog with the knowledge beyond. I knew right away that we are experienced and safe hands. I did three dives, although I could have done up to five, which says a lot about the excellent service I received. However, I also wanted to leave time for snorkelling which was also a wonderful experience. We were the only ones on the Milln reef, and it emphasized the exclusive atmosphere of the trip. The dives were in exceptional locations, and since I was the only certified diver this time, I dived one-to-one with the instructors, Teddy and Vanessa, and the dives were done at my pace.

Teddy and Vanessa took care of everything regarding the dives. The equipment was always ready and in excellent condition. I had a comfortable and confident feeling while diving, even though it had been a while since my last dive. I dived with them in caves and hollows and felt like I could see everything possible underwater. The experience was made richer by the opportunity for a night dive which gave a new perspective on the underwater world.

We saw countless different fish, reef sharks, turtles, and dolphins on the trip. The whole experience was one of the most unique of my life, as the coral reefs are indeed one of the world's seven natural wonders.

I recommend the Coral Sea Dreaming to anyone who wants a high quality, devoted and intimate trip to the reefs – where you will not be treated as a tourist but as a friend.

SoileAn Absolute 5 Star Experience

Really fabulous value for money. We took Mr 20 and Mr 16 and the 4 of us had a blast. The parents snorkelled- fantastic and the ‘kids’ had their first dive experience. This included a night dive. Teddy and Joey totally looked after them in and out of the water.
The food was honest, super fresh, tasty and lots of it! Joey’s chicken tacos … a hit.
Phil, the Skipper, told wonderful stories and we felt in safe hands. His reef knowledge is staggering and he shared so much with all of us.
We sailed back into Cairns which really capped off an already terrific trip..
Thank you to all three crew members. From our family, we wish you all the best.

We slept under the stars on the deck and it was ….. well sublime.

Thanks, also to the two couples that joined us, great people and great company.

What a weekend!
Huge thanks to the crew - Roman, Vanessa, Remy and Ellie. They took such incredible care of each one of us.

A special mention must go to Vanessa - she handled myself and all the other first timers with such professionalism and made us feel instantly comfortable in the water. I'll never forget my first dive with her. It truly felt like being introduced to a whole new world below the surface. It was so joyful to explore the reef and see and interact with all the little creatures she pointed out. What a beautiful birthday gift that was.

By the time the second day rolled around I was confidently swimming around at 11-12m without needing to hold a hand, and I was fluent in diver sign language. I know Ellie and Vanessa were proud.

I was too busy enjoying myself to get many photos, but I'll be back just as soon as I can. Thank you again CSD team!

CatherineAn Unforgettable Experience

We originally went out with the Coral Sea Dreaming crew in January 2021 and it was excellent! So much so we organised another trip to Cairns mid-year mainly so we could go out with them again. Unfortunately COVID has managed to get in the way, but I just wanted to shout out to the team for being amazing with excellent customer service. Our first trip in January had to be pushed back to later in the week because we had received a test and isolate order on arrival and weren't sure we were going to make the departure time - no problems at all and were able to reschedule seamlessly and the 2 days out at Mill'n reef were awesome. This time we were originally supposed to travel in June but got locked out of QLD due to an outbreak. Nat and the team were amazing and allowed us to reschedule to a later date. This time we managed to get to Cairns but unfortunately no-one else on our fully booked boat could get into the state due to lockdowns and the sail date was cancelled☹️. Alas none of the other available sailing dates fit with our itinerary so the team at Coral Sea Dreaming arranged for us to go out with another provider. Throughout it all the team has been a pleasure to deal with, accomodating and have communicated clearly. While we are saddened we can't get out with them this time we will definitely try again in the future and will be recommending them to all our friends.

AnnaExcellent Customer Service



With a maximum of just 12 passengers and 3 crew, Coral Sea Dreaming offers a very unique alternative to the large live-aboard experience. Small group numbers diving and snorkelling, means you see more creatures, experienced divers enjoy longer dive times and first time divers receive one on one training with no rushing. This is your adventure of a lifetime!
