Guerrilla Bay - Sydney & New South Wales
Blue Island, or L’ile bleue, is one of those sites that feels like you've stumbled onto a secret. It’s an isolated peak just outside Cook’s Bay, and you'll often find us heading here on days when the visibility is really singing, otherwise it’s a bit of a gamble. The dive starts with a swim out into the open blue, a lovely, slightly disorienting feeling, before the coral canyon starts to emerge from the haze. We love the canyon itself; it’s a shallow, intricate labyrinth, maximum 16m, packed with huge anemones and their resident clownfish. Keep an eye out for the big schools of jacks swirling around the edges – they can be truly mesmerising. If you're comfortable drifting a bit deeper into the blue, maybe 25-30m, you might spot white-tip sharks cruising past, and we've had some lovely encounters with hawksbill turtles here too. It’s a pretty easy dive once you’re in the reef, but that initial blue water swim means it's best for divers who are comfortable with some open water exposure.
