Great Barrier Reef Coral Spawning Trip

Great Barrier Reef Coral Spawning Evening Trip

Seize the opportunity to witness the remarkable annual coral spawning phenomenon on the beautiful Great Barrier Reef during Tusa Reef Tour’s premium evening tour.

Annually, in the wake of a full moon during the late spring or early summer, nature orchestrates an awe-inspiring spectacle where every coral on the reef partakes in synchronized reproduction.

Prepare to be captivated by the intricacies of coral reproduction, a majestic spectacle beyond compare. Millions of minuscule cells burst forth from the coral, reminiscent of effervescent champagne bubbles. This dramatic event, lasting only a couple of nights, heralds the arrival of infant corals as they find their place upon the reef to flourish and thrive.

Embark on a night-time coral spawning expedition that promises to be memories you will hold onto for a lifetime. Tusa Reef Tours offers specialized Great Barrier Reef coral spawning night trips departing from Cairns, catering to both divers and snorkelers, where you can witness this extraordinary natural phenomenon before returning to Cairns.

Limited to a maximum of just 40 guests, our evening trip offers the highest level of service, with the lowest guest-to-crew ratios of any Great Barrier Reef tours from Cairns. From the moment your step aboard, our highly trained and knowledgeable crew and marine guides will be on hand to ensure an exceptional evening on the Great Barrier Reef. Your journey to the outer reef will be a short 90-minute voyage, during which you’ll enjoy a full briefing from our Marine Guides on the activities for the evening.

Whether you are a seasoned diver or a beginner snorkeller, our guides will be there to assist you every step of the way. They will point out the best spots to explore and help you identify the vibrant coral and marine life that surrounds you. You will also be provided with unique waterproof bone-conduction underwater headsets that have special Coral Spawning commentary for the evening.

After your snorkelling or diving experiences, fuel up with a delicious dinner prepared with local ingredients and local beers and wines to savour on the journey back from the reef. Throughout the evening, our marine guides will share their extensive knowledge about the Great Barrier Reef ecosystem, and our Master Reef Guide will share a unique Coral Spawning presentation.

Please note: Tusa Reef Tours trips are restricted exclusively to people aged 12 and over, ensuring an optimal experience for all our guests. For our Coral Spawning trips, only Certified Diving and Snorkelling will be available. Introductory Diving will not be offered.

Come aboard and embark on an unforgettable adventure where nature’s beauty unfolds, and the wonders of the underwater world come to life.

"Exceeded expectations! The snorkeling was amazing. So much to see. The giant clams blew my mind. The boat is clean, modern, and comfortable, with good loaner equipment (mask, snorkel, fins, etc.), and a light and delicious lunch buffet served between the two dives. But perhaps most importantly, the crew and management are skilled and highly professional.Thanks Tusa! Highly recommended." (Google Review: August 2022)

Yes! For our trips, you’ll be travelling on the same vessel as all our other passengers – so if your travel partners are certified divers and others in your group are not, you’ll share your journey out on the reef together and complete your dives/snorkel experiences at the same sites.

You will also be asked to fill out an assessment form before snorkelling. If you are assessed as an at-risk snorkeller you may be required to wear a flotation device while snorkelling.

We strongly recommend travel insurance to cover you if your snorkel or dive trip is cancelled due to illness, poor weather, travel delays, lost luggage and legal costs. Travel insurance may not cover diving accidents and/or treatment/evacuation. For that we recommend separate insurance – see our Dive Insurance page for more information.

All equipment is included in the trip cost. For a snorkeller, this includes a snorkel, mask, fins, wetsuit, and waterproof headset for the audio commentary.

As long as you’re comfortable in the water, you should be able to snorkel or even do an intro dive. Before you enter the water you will fill out a form that includes information on your level of competence in the water and any medical conditions. Depending on your response, we may require that you use a flotation device while snorkelling.

Our friendly instructors will talk you through using all the equipment. If you’re unsure, feel free to contact us to discuss.
