Monkey Point - Salt Island & Cooper Island

Post Office Rock, deep in Fiordland, isn't your average dive. It’s a site that really forces you to slow down and look. We love the dramatic topography, a rocky reef that slopes down to a sand floor around 18 metres, draped in those long, swaying kelp fronds. Visibility can be a bit variable, averaging around 11 metres, but that’s part of the charm here; it adds to the mysterious feel. Keep your eyes peeled for the smaller stuff – we've spotted iridescent Oblique-swimming Triplefins darting between rocks and the unusual Eleven-armed seastars clinging to the walls. The sheer volume of Pintado Petrels and Sooty Shearwaters flying overhead during your surface interval is a show in itself. On the reef, Cowfish drift past, and the Butterfly Perch are almost always present, their colours a striking contrast against the darker rock. Our tip? Go slow, let your eyes adjust to the low light, and really search the nooks and crannies. This isn't a site for chasing big pelagics, though the occasional Rig or even a curious Seven Gill Shark might glide past. Instead, it’s about appreciating the unique Fiordland ecosystem, a truly distinct dive experience that rewards patience and a keen eye. It’s perfect for those who appreciate temperate water marine life and a dive that feels genuinely wild and remote.
