StandoutExceptional marine biodiversity

Deep Boulders really delivers on its name. You drop onto a steep slope, then follow it down to these colossal rock formations, some of them the size of small cars, starting around 20 metres. We love how the light plays through the gaps and crevices down here, creating some dramatic shadows. Keep an eye out for the Dusky Cusk and the Saddle Stargazer – we’ve had some cracking encounters with both. Our favourite part is pushing a bit deeper, down to 27 metres, to a specific ledge where we often find nurse sharks resting. It's a proper hideaway for them. The dive finishes with a drift around the point into Moonhole, which is a nice gentle end after the deeper exploration. Visibility usually hits around 20 metres, so you’ve got good views of the schools of grunts and creole wrasse swirling around the boulders. It’s a site for those who appreciate a bit of topographical drama and aren’t afraid to go a little deeper to find those bigger creatures.
