ABC Bay - Poor Knights Islands

ABC Bay, despite its relatively shallow maximum depth of 7m, is one of our favourite spots at Poor Knights. You’re not here for dramatic drop-offs, but for the sheer density of life tucked into every crevice of the kelp-draped rock wall. We particularly love poking around the darker spots, often finding a Spitlure Frogfish camouflaged perfectly, or coming face to face with a grumpy-looking Crested Blenny. The visibility averages 8m, which isn't gin-clear but honestly, it’s perfect for the intimate scale of this dive. The sandy patches are great for spotting Smooth Skates, and sometimes you'll even catch Pacific sardines shimmering past in thick schools. It's a fantastic site for macro enthusiasts and anyone who enjoys a slow, deliberate exploration. If you visit in winter, keep an eye out for playful seals zipping through the kelp. This site is ideal for photographers and divers who appreciate the smaller, often overlooked inhabitants of the reef.
