Brady’s Corner (Shark Fin Cave) - Poor Knights Islands

Brady's Corner, or Shark Fin Cave as we usually call it, is one of our favourites at Poor Knights. It's not about the deep, dramatic stuff here. Instead, you're looking at a truly unique cave system, shallow enough that the light still penetrates, painting the walls with shifting blues and greens. We love drifting through the main chamber, feeling the slight surge as it pushes you gently past walls thick with orange cup corals and sponges. You’ll often find snapper schooling just inside the entrance, lazily circling, and we’ve spotted big long-nosed butterflyfish picking around the edges of the reef. The real magic happens when you look up though; the "shark fin" rock formation that gives the cave its nickname is striking, especially when the sun hits it right. Keep an eye out for blue-eyed triplefins darting in and out of crevices, and if you’re lucky, a mako shark might cruise by the entrance in the deeper blue. It’s perfect for new divers or anyone who appreciates the quieter beauty of a well-lit cave dive.
