Snorkelling aboard SeaQuest

Snorkelling is the easiest way to discover the Great Barrier Reef, it is as simple as breathing. If you have never snorkelled before, don't worry, a briefing is held on board, explaining how to put and use the snorkelling gear. All of the snorkelling equipment you will require is supplied as part of your trip, including a wetsuit or stinger suit. Prescription masks are also available upon request.

SeaQuest is our liveaboard transfer vessel and offers the budget conscious great value for money with the chance to experience unlimited snorkelling at two separate reef locations on the Outer Reef. This purpose built vessel departs daily and comfortably carries up to 80 passengers in air-conditioned bliss to the Norman, Saxon, and Hastings Reef systems.

If you have never snorkelled before we will teach you how to put on and get the most out of the snorkelling gear and assist you into the water to enjoy your first taste of The Great Barrier Reef. If you are a snorkeller extraordinaire or even somewhere in the middle we will get you out and about finding some of our friendly residents. 

Intro Dive

Intro Dive aboard SeaQuest

Want to go SCUBA diving, but don't want to go through the whole PADI course. Why not discover SCUBA diving with an introductory dive!! Nothing compares to the first breath you take underwater, or the feeling of weightlessness, or even coming face to face with an underwater critter that you have only ever seen on TV.

Introductory Diving is a program designed for those that have no official SCUBA certificate. These dives are under supervision of our highly qualified dive instructors and there will be a maximum of 4 divers with 1 instructor. You will go to a maximum depth of 12 m (40ft) and these dives generally last around 1/2 hour. 

​On the way out to the Great Barrier Reef our friendly and experienced instructors will give you a briefing on what to expect and what procedures will be followed to ensure that your first breaths underwater are a safe and unforgettable experience.

Once you arrive at the reef, you will get comfortable with your equipment by practicing on the surface. Once you are comfortable with those skills, you practice them again only this time with the added thrill of being underwater! Finally when you feel comfortable, it's time to dive. Relax, Breath in, Breath Out, repeat as necessary and most of all enjoy!!!


Certified SCUBA aboard SeaQuest

Cairns' warm waters offer excellent conditions to enjoy your diving experience. With more than 1,000 different species of fish, you will be amazed by all the diversity the Great Barrier Reef has to offer. 'Nemos', Parrotfish, shy Sharks, a friendly Mahori Wrasse called Wally, Turtles, and many more creatures. 

During your day trip, you will be able to dive in two different locations on the reef, chosen according to the weather conditions and the safety and enjoyment of our customers.

All equipment that you require is included in the course cost. All our dives are certified buddy dives but if it has been awhile since you last dived or if you just want to cruise and let someone else remember where the boat is then dive guides are available for an additional cost. (HINT: they also know where all the cool things are!!)

Make sure that you remember to bring your certification card and your logbook with you for a friendly crew member to see.

One of the best experiences of my life! We had three amazing days on the boat and saw everything we wanted to see. Thanks to the whole crew that was really nice and funny. Special thanks to Kat! She was a great instructor and guide, especially at the night dive! We'll never forget it!
