Port Macquarie Artificial Reef sits at 44 to 46 metres, placing it firmly in deep diving territory with mandatory decompression planning before you splash. Strong currents sweep the wall and reef structure, which is exactly what draws pelagic species in numbers. Visibility runs 15 to 30 metres, so you can watch schools of kingfish, trevallies, and amberjack work the current from a decent distance. Samson fish, pearl perch, bar cod, snapper, mulloway, and morwongs round out a solid pelagic and reef fish assemblage. Nitrogen narcosis is a genuine consideration at this depth, and current timing is critical. Boat access only.

Bird Rock is a shore-entry reef dive in New South Wales where Grey Nurse Sharks and rays are the main draw. The reef sits at 12 to 13 metres, a comfortable depth for beginners to explore without feeling rushed. Visibility typically ranges from 5 to 10 metres, giving you enough range to take in the surroundings. There is no current to manage here, which keeps things relaxed, but be aware of surge, which is a gentle push-and-pull motion caused by surface swell that can move you around near the reef. The best months to visit fall in the warmer summer and autumn period, from December through to April.

Cod Hole is a sheltered reef dive off New South Wales that suits beginners well, with no current and depths ranging from 6 to 16 metres. Visibility typically runs 10 to 20 metres, giving you plenty of time to spot what lives here. The reef holds wobbegong sharks and Port Jackson sharks resting on the bottom, so take your time scanning ledges and sandy patches. Grey nurse sharks also frequent the site. Soft corals and sponges give the reef structure colour and texture, and nudibranchs reward anyone who slows down and looks closely. Boat traffic in the area is the main hazard, so stay aware when surfacing.

Shelly Beach Lagoon is a sheltered, shallow entry point that suits first-time snorkellers and beginner divers well. The lagoon combines a small reef with seagrass beds, giving you a chance to spot crabs and starfish in calm, easy conditions. Visibility is variable, so some visits will reward you with clear water while others are murkier. A mild current runs through the area, and a rip current can develop near the lagoon edges, so stay aware of your position and keep clear of any interaction with marine life. Dolphins are occasionally seen offshore, though sightings are not guaranteed.

Korogoro Creek is a calm, shallow estuary snorkel and dive spot sitting within Hat Head National Park. With depths of just 0 to 2 metres, this is a gentle introduction to underwater exploration, though visibility can vary considerably depending on conditions. The seagrass beds are worth slowing down for: flatheads rest motionless on the sandy bottom, octopus tuck themselves into crevices, and wobbegong sharks lie camouflaged and still. Mullet move through in loose schools, and hermit crabs go about their business in the shallows. Check conditions before entering, as rip currents and breaking waves can develop near the creek mouth.

Wall is a boat-access dive site off New South Wales where a vertical drop takes you from the surface down to around 22 metres. Visibility can reach 30 metres in good conditions, making it easy to see what's clinging to the wall: soft corals, sponges, and nudibranchs in the shallower sections, with cuttlefish and octopus tucked into crevices. Wobbegong sharks rest on ledges, and grey nurse sharks and pelagic fish move through the deeper water. Port Jackson sharks and weedy sea dragons are also regular sights. Current is generally mild, but beginners should stay aware of depth, as it's easy to drift down further than planned.

Yabbies is a boat-access reef dive off New South Wales, reaching depths of 12 to 33 metres. The deeper sections put this firmly into deep diving territory, so beginners should stay within recreational limits and keep a close eye on their depth gauge. When conditions are good, visibility stretches to 30 metres, making it easy to read the reef and stay oriented. Currents tend to be mild, which helps if you're still building confidence underwater. The reef supports a variety of local species typical of NSW waters. January through March generally offers the most reliable conditions for this site.

Black Rock is a reef dive off New South Wales that rewards beginners with a genuine mix of reef life at manageable depths. The shallower sections sit around 8 metres, making it easy to get comfortable before venturing into deeper waters reaching 22 metres. Visibility swings considerably, from 3 metres on murky days up to 30 metres when conditions align. Current runs moderate, so stay aware of surge near the reef. Look carefully along the reef structure for wobbegong sharks resting flat, octopus tucked into crevices, moray eels, scorpion fish, and the delicate detail of nudibranchs and egg cowries. Grey nurse sharks and turtles also pass through. Give lionfish and sharp coral a wide berth.
