The Grotto - Victoria

Navy Pier isn't just a dive site, it's a spectacle, and frankly, one of our favourite dives in Australia, full stop. Dropping down beneath the pier, the sheer density of fish life is almost overwhelming. We’re talking schools of blacktip soldierfish so thick they dim the light, clouds of bream swirling around the pylons, and those magnificent giant groupers, often just hanging out under the shadows. It’s a sensory overload, in the best possible way. You’ll want to take your time here, peering into every crevice for a bluespotted shrimpgoby or a camouflaged frogfish. Our pick for an insider tip? Go at high tide for the best visibility, and keep an eye out for wobbegongs tucked into the sand flats beneath the structure. Night dives here are something else entirely, with lionfish on the prowl and cuttlefish flashing their colours. This dive is perfect for macro fanatics and wide-angle enthusiasts alike, truly a standout for any diver visiting Ningaloo.
