HMNZS Waikato wreck - Poor Knights Islands

Lucy’s Wall, for us, is one of those sites that proves you don’t need depth or dramatic topography for a truly rewarding dive. It’s a shallow muck dive, rarely deeper than 7m, tucked away near a breakwall – perfect for a relaxed hour or two when you just want to potter. We often head here for a macro fix or to try out new camera gear without fighting current. The real magic here is spotting the tiny, the camouflaged, and the just plain weird. You’ll spend most of your time with your nose just inches from the sandy, silty bottom, hunting for things like the cryptic Long-tailed Dragonfish, which blends in perfectly, or the comical Freckled Anglerfish. We’ve had great luck finding Tasmanian Blennies here too, darting between the bits of shell and sparse weed. Visibility averages around 4m, sometimes less, but that forces you to slow down and really look, which is exactly what muck diving is about. It’s not for big pelagics, but if you love searching for the small stuff, Lucy’s Wall delivers.
