Santa Rosa Wall - Cozumel

Terrigal Haven, just an hour or so north of Sydney, is one of those places we keep coming back to. Forget the big, dramatic walls; this spot is all about the small stuff, the hidden gems you really have to look for. It’s mostly sand and seagrass, shallow too, maxing out at about 11 metres, which means plenty of bottom time to really scour the habitat. Our favourite approach is a slow drift over the seagrass beds, keeping an eye out for movement. We’ve spotted Great Stingarees half-buried in the sand, just their eyes peeking out, and occasionally a Yellowback Stingaree cruising past. The Pipefish here are fantastic, blending in perfectly, and we’ve found some unusual nudibranchs we haven’t seen anywhere else. Visibility hovers around 6 metres on a good day, so it’s not about seeing huge distances, but rather the macro details. It’s a photographer’s delight and perfect for anyone who loves a slow, methodical critter hunt.
