The Outpost - Poor Knights Islands
Alcyone. Just the name brings back that metallic taste of salt and adrenaline. This seamount is what everyone pictures when they think of Cocos, and frankly, it delivers. We’re talking about getting dropped onto the crown of a submerged peak, then sinking down into hundreds, sometimes thousands, of hammerheads. They swirl around you, a silent, grey storm of muscle and fin. Seriously, the sheer number of sharks here can be dizzying. Our favourite approach is to drop in, tuck ourselves behind some rocks around 20-25m, and just wait. The surge is often present, a gentle push and pull against your body, but it’s worth it. You’ll see whitetips blanketing the bottom, and if you’re lucky, a marble ray or eagle ray will glide past the main event. Keep an eye on the blue for a passing whale shark, though the hammerheads are the main show. This dive is for experienced divers comfortable with current and deep water, who are ready for an unparalleled shark encounter.
