Marley Point is a reef and cave dive in New South Wales that rewards experienced divers willing to work with the conditions. Depths run from 5 to 35 metres, and moderate current combined with surge demands solid buoyancy control throughout. Visibility ranges from 5 to 25 metres depending on conditions, with the clearer water typically rewarding visits in May and November. The cave systems and sponge gardens provide structure for wobbegong sharks, Port Jackson sharks, and eastern blue devilfish. Patient divers scanning the reef carefully turn up weedy seadragons and nudibranchs, while Australian giant cuttlefish and nurse sharks round out what is a genuinely varied temperate assemblage.

Wottamolla is a boat dive site off the New South Wales coast combining reef and wall diving at depths of 18 to 27 metres. Visibility can swing considerably, anywhere from 5 to 20 metres depending on conditions, so checking forecasts before you head out is worth the effort. There is no current to manage here, which makes working the wall and exploring the reef structure more comfortable once you account for the depth. The site suits intermediate divers who are confident managing their air consumption at depth and can handle variable visibility without losing situational awareness. Various reef species populate the site throughout the year.

Wattamolla Lagoon is a sheltered shore entry site in New South Wales that suits first-time snorkellers and beginner divers well. The water stays shallow and calm, making it forgiving for those still building confidence underwater. Visibility varies depending on conditions, so clearer days reward patient visitors. Keep an eye out for Eastern Blue Groper moving along the reef, wobbegong sharks resting on the bottom (give them space), stingrays gliding across sandy patches, sea turtles, and a variety of colourful fish. The mild current means you can focus on observing rather than battling the water. Parking and toilets are available on site.

Barrens Hut combines reef, wall, and drop-off terrain in a single boat dive, with depths running from 12 to 28 metres and visibility frequently reaching 35 metres in the clearer months. Moderate currents keep the water productive but demand attention, particularly along the wall where the drop-off accelerates flow. Gorgonians colonise the deeper structure, and patient divers regularly encounter Port Jackson sharks, wobbegong sharks, and Australian giant cuttlefish resting on the reef. Yellowtail kingfish work the mid-water column, while eastern blue groper and sea pike move through the shallower sections. Watch for nudibranchs on the reef face and stay clear of sharp coral on the wall.

Waterfall lives up to its name with a dramatic wall that plunges from 12 to 28 metres, creating the sensation of descending over an underwater cliff face. This boat-accessed site off New South Wales rewards intermediate divers with a varied reef structure and reliably good encounters with local species. Visibility ranges from 5 to 15 metres depending on conditions, with mild currents making the wall descent manageable for those comfortable at depth. The reef hosts a solid cast of temperate marine life. Eastern blue devils patrol the mid-depths, while blue groper cruise the wall face with their characteristic curiosity. You'll spot Port Jackson sharks resting in crevices, wobbegong sharks camouflaged against the reef, and schools of yellowtails moving through the water column. Snapper and bream tend to gather near the drop-off edge, with red morwong holding station around rocky outcrops. Cuttlefish make regular appearances, particularly during breeding season. The site requires attention to depth management and awareness of boat traffic overhead. Surge can pick up along the wall, so maintain good buoyancy control throughout the dive. The dramatic topography and depth variation make this an engaging site for divers ready to handle slightly more challenging conditions.

The SS Undola sits at 43 to 45 metres in New South Wales waters, putting this wreck firmly in technical diving territory where decompression obligations and moderate currents demand solid dive planning. Visibility of 20 to 30 metres rewards that preparation, giving you clean sightlines along the hull and the adjacent wall. The wreck structure harbours conger eels, moray eels, serpent eels and numbrays tucked into the darker recesses, while yellowtail and seapike work the water column above. Seals occasionally pass through, and sunfish have been spotted in the blue. Sea pens colonise the surrounding terrain. April through September offers the most reliable conditions.

This drift dive runs from Bass and Flinders along the coast to Oak Park, carried by a moderate current through easy shallow waters of 3 to 8 metres. Visibility typically ranges from 5 to 10 metres, giving you a clear view of the rocky reef below. Keep an eye out for eastern blue devilfish tucked into crevices, cuttlefish hovering near the bottom, and crayfish sheltering under ledges. Sponges and sea tulips colour the reef, while yellowtail, mados, seapike, and leatherjacket move through the water column. Surge can be noticeable, and boat traffic is active in this area, so stay aware of your surroundings and keep well clear of any lines or kelp to avoid entanglement.

The 4th-5th Reefs sit at 15 to 17 metres off the New South Wales coast and offer a solid mix of temperate reef species that reward patient, observant divers. Visibility typically runs 5 to 10 metres, giving you enough range to scan the bottom for resting angel sharks and wobbegong blending into the substrate. Keep a closer eye on rocky ledges and crevices for Port Jackson sharks and the vivid eastern blue devil. Weedy sea dragons and cuttlefish appear regularly, while schools of yellowtail, luderick, and old wife move through mid-water. There is no significant current, so you can take your time. Boat traffic is the main hazard, so a surface marker buoy is essential.
