Cod Hole - Great Barrier Reef

Cod Hole is one of those places you hear about before you ever dip a fin in the water, and we’re happy to report it lives up to the hype. It’s the giant potato cod, of course. We’re talking individual fish the size of small humans, gliding slowly past, often so close you could reach out and touch them (please don't). They’re curious, these big fellas, accustomed to divers, and they certainly make for some incredible photos. We love dropping in early, just as the sun starts to properly warm the water, to see them cruise out from under ledges. Beyond the cod, which are the main event, the reef itself here is healthy, plenty of hard corals, and we’ve often spotted Maori wrasse poking around. You’ll also get your usual reef suspects: big schools of fusiliers, sleek unicornfish darting about, and the occasional triggerfish eyeing you up. It’s a pretty easy dive, generally mild currents, making it a great spot for almost any diver keen to get up close with some truly massive fish. Just expect a few other boats to be there; it’s popular for a reason.
