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.

The SS Tuggerah sits at 45 to 48 metres off New South Wales, putting it firmly in technical diving territory where decompression planning and narcosis management are non-negotiable before entry. Visibility runs 15 to 30 metres depending on conditions, giving you a solid read of the wreck structure when the water is at its clearest. Strong currents are a consistent factor here, so buoyancy control and positioning matter throughout the dive. The wreck holds wobbegong sharks, eels, and octopus tucked into its structure, while schooling yellowtail, bullseye, and snapper work the water column above. Grouper, blue wrasse, and trumpet emperor round out the resident population.

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.

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.

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.

Lilli Pilli is a shore entry site in New South Wales that suits beginner divers well, with a gentle current and depths reaching 22 metres in the deeper sections. Visibility runs between 2 and 10 metres, so conditions vary and you may need to take your time finding things. That patience pays off, because the site rewards slow, attentive diving. Keep an eye on rocky or sandy patches for camouflaged wobbegong sharks, octopus, and cuttlefish. Seahorses and pygmy leatherjackets turn up for those who look carefully, while blue groper, yellowtail kingfish, striped catfish, and moray eels round out the mix.

Ship Rock Aquatic Reserve delivers a dynamic shore dive that rewards intermediate divers comfortable with changing conditions. The site's strong currents transform this into an exhilarating drift dive along a rocky wall, where depths range from 3 to 18 metres and visibility typically sits between 5 and 15 metres. The marine life here reflects the nutrient-rich waters flowing through the reserve. You'll find pineapplefish tucked into crevices, their distinctive scales catching your torch beam. Decorator crabs and spider crabs work the rocky surfaces, while moray eels and conger eels peer out from darker recesses. Cuttlefish drift past the wall, and schools of fish move with the current. Look closer and you'll spot nudibranchs on the rocks, whilst estuary catfish patrol the shallower sections. The current demands respect and proper planning. Time your dive with the tide tables, and always deploy a surface marker buoy well before your ascent. Boat traffic above can be significant, so your SMB becomes essential safety equipment rather than optional gear. The shore entry requires confident water skills, particularly when surge picks up. Available year-round, the reserve offers consistent diving when conditions align with your experience level.
