About the Event

Here on  the Sunshine Coast, we are home to the most biodiverse population of nudibranchs in the world. This is a monthly event to learn more about nudibranchs – some of the ocean’s most colourful and bizzare little animals.

There’s nothing like these colourful hermaphrodites – and there are over 3,000 species. Nudibranchs are animals that have their lungs exposed, some are transparent, some are solar-powered, and we are discovering more about them every day.

The dives will be led by nudibranch expert Gary Cobb who, has dedicated years of research into identifying and recording information on nudibranchs on the Sunshine Coast. 

Photographers, naturalists, nudibranch enthusiasts and first-timers are all welcome to join the fun!

These animals can make for the perfect macro subject, as they are relatively slow moving, have so much colourful contrast, and are very interesting to watch.

What you can expect

Check in at Sunreef starts at the time outlined on your confirmation email or text. When you arrive, we will see you at our check in desk and ensure that your gear is organized. If you bring your own gear, our crew can carry it down to the dock where you can set up the gear. If we know you are hiring gear, everything will be organized for you prior to check in. 

On departure to the location, our nudibranch expert for the day will explain which species we are expected to see on the dive, which will be a bit of a treasure hunt. Sometimes we may even get a few surprises. The dive site for the day will be depending on the day’s weather and sea conditions, and recent sightings, as we always do what we can to give our guests the best experience. as we always try to give you the best experience. Once the boat exits the calm waters of the Mooloolaba River system, it is around a 15 minute ride to the site. The vessel will be moored and our crew will help you set up to get in the water.

Each dive is planned to last for either 50 minutes or will end to have you on the surface with 50 bar (whichever one comes first). Divers please note that during this dive  you may be stationary for long periods of time, please dress accordingly to ensure you are comfortable with your body temperature.

We will then resurface for a surface interval before the second dive. We encourage you to ask any questions you may have to our nudibranch experts before your second dive. Occasionally, our experts may even gather organisms to bring to the surface for us to examine, before bringing them back down on the second dive.

The divers then return to the shop, where we will unload the vessel and wash all your gear for you if you so wish. 

There will be a post-dive debrief, where our nudibranch experts will give a presentation about the nudi world. Each month brings a new presentation with different focuses. Our past presentations included monstrous nudibranchs, hard to find nudibranchs, and rare nudibranchs of the Sunshine Coast.
