Kadavu and the Great Astrolabe Reef. This place feels like a proper expedition, not just another dive trip. We’re talking about one of the biggest barrier reefs on the planet, and honestly, it still feels wild. The currents here can be lively, which is exactly what keeps the reef so healthy and brings in the bigger stuff. We love a good drift dive through channels where the water just zips you along, past immense staghorn coral gardens. Keep an eye out for the Crossroads Reefgoby, they’re tiny but everywhere if you look closely. Our favourite spots are often on the outer walls, where you get that deep blue drop-off. You’ll definitely see silvertip sharks patrolling the edges, a truly impressive sight. If you’re lucky, and timing is everything, the manta rays show up in numbers, often between May and October. We’d suggest going early in the morning for those encounters, before the sun gets too high. There's a particular joy to a muck dive around some of the shallower bays too; we’ve spotted cowries and the oddly charming Brown Snake Moray there. It’s not always about the big pelagics, though Kadavu certainly delivers on those. The sheer scale of the reef means you rarely see another boat, which is a rare treat these days.
