Why dive here
With 154+ marine species recorded in the area - including hammerhead sharks, sea turtles, tiger sharks and napoleon wrasse - Sea Reef offers some of Great Barrier Reef's richest reef diving. Water ranges 24-30°C, warmest January, February, March.
Lloyds Rock Reef, out there in Nova Scotia, is a spot we always enjoy getting back to. It’s not the tropics, obviously, but for cold water diving, it’s got a particular charm. The visibility can be quite decent, often 10-15 metres, which is enough to appreciate the rocky structures and the surprising amount of life clinging to them. We love dropping in and watching the velvet scoters dive down with us, like curious companions. The rock walls are covered in scarlet sea anemones, popping against the darker stone, and you’ll often find American lobsters tucked into every crevice, waving their antennae. Keep an eye out for moonfish gliding by, and we’ve had some fantastic encounters with snake blennies poking their heads out from under rocks. It’s a site that rewards a slow, methodical dive, really letting you observe the smaller details. If you’re into temperate water marine life and don't mind the chill, Lloyds Rock Reef is a solid pick. It’s excellent for photographers wanting to capture something a bit different from the usual tropical fare.
