    StandoutExceptional marine biodiversity

    Cornelius Bay is one of those sites we always recommend to divers who appreciate a little effort for a decent reward. It’s tucked just left of the Sea Aquarium, and honestly, the entry can be a bit of a scramble down some rocks, so wear sturdy boots. But once you fin out, you’re greeted by some seriously impressive elkhorn coral formations in the shallows – really broad, healthy plates. Our favourite part has to be the drop-off where the reef descends to about 19 metres. The visibility here is typically 25 metres, and it feels like swimming through liquid glass. We’ve spent hours just watching the yellowhead jawfish darting in and out of their burrows and spotting emerald sleepers resting on the sand. Look closely for boarfish; they’re surprisingly common here, and the spot-tail golden bass is another regular visitor. For photographers, the finger coral provides a stunning backdrop, and the sponges add a nice splash of colour. It’s a quiet dive, usually uncrowded, and perfect for a relaxed afternoon exploring the reef at your own pace.
