    Peach Grove at Great Mercury Island is one of those spots we wish we could keep to ourselves. The beach itself is stunning, and the diving matches. At 13m max depth, it’s a brilliant site for newer divers or anyone who just wants a relaxed, easy dive. The real draw here is the mix of habitats: kelp forests that sway with the surge, patches of reef, and sandy gutters. We always find something interesting, from the big Oblique-swimming Triplefins darting around to the Short-tail Stingrays that often glide over the sand. It’s also a nursery, so keep an eye out for baby crayfish tucked into crevices – we’ve seen sooty shearwaters here too, diving from above. Visibility averages 9m, which is decent for the area, and we often find the conditions are calmest in the morning. It’s not about huge pelagics here, but the smaller, more intimate encounters.
