The Plateau - Poor Knights Islands

The Vis Island Wall isn't just a wall, it’s an entire ecosystem built around a history lesson. We've always found ourselves drawn to sites that tell a story, and this one whispers tales from WWII, with a good-sized wreck resting against the drop-off. You descend onto the deck, maybe 25-30 metres, and the first thing that hits you is the sheer scale, the way it leans into the blue. What makes it special for us is how the wreck has become part of the reef. Scarlet coral blazes bright red in the torchlight, and we’ve seen hake tucked into every crevice, alongside shy blotched picarel. Keep an eye out for the odd cowfish grazing on the metal hull, and once, we even spotted a brown skate gliding over what used to be the cargo hold. This is a dive that suits those who appreciate a wreck with a living, breathing component, not just rust. Go early in the morning, before any wind picks up, for the best light on the coral.
