Meet the site
This unassuming shore dive inside the mouth of the Tweed River, close to Jack Evans Boat Harbour, has become one of the better-known muck and critter dives on the northern NSW coast, prized far more for what lives among the rubble than for any scenery. The site sits on the last bend of the river before it opens to the ocean, where a low rock wall and adjacent sandy/silty bottom in 3 to 12 m create a sheltered nursery habitat quite different from anything on the exposed reefs outside. Because the river channel brings a steady recruitment of tropical larvae down from the north on the East Australian Current, particularly through late summer and autumn, this is one of the most reliable spots in the region for juvenile tropical reef fish well south of where you would expect to find them, alongside a resident population of frogfish, ghost pipefish, shrimp gobies and their commensal shrimp, blennies, scorpionfish and moray eels working the cracks in the rock wall. Butterflyfish, angelfish and leatherjackets pick over the structure, and by torchlight at night the site comes even more alive with nocturnal crustaceans and cephalopods. The catch is the tide: this is a genuinely tidal site, with a real current running in and out of the river mouth, so it must only be dived on the incoming tide or at high slack, when the water is calmest and clearest — diving on the ebb risks being swept out toward the river bar and open ocean. Visibility is never great by reef standards, typically 5 to 10 m and often driven by how much rain has fallen upstream in the preceding days, but that murk is part of what makes this a genuine muck-diving destination rather than a scenic dive. It requires no boat, making it an easy, low-cost, high-reward option for shore-based photographers and macro enthusiasts, and it doubles as a convenient night dive and a training venue for local dive shops, provided divers respect the tide window and keep a float up for the boat traffic that shares the harbour.
