Broughton Island offers a varied underwater terrain of walls, canyons, caves, and reef structures that rewards intermediate divers willing to work with moderate currents. Depths run from 8 to 21 metres in the deeper sections, with visibility typically between 5 and 10 metres. The site is well-regarded for its grey nurse sharks and Port Jackson sharks, which shelter around the rocky structures alongside wobbegong sharks resting on the bottom. Blue groper, groupers, eastern blue devilfish, and trumpetfish move through the reef, while eagle rays and turtles make regular appearances. Surge can be a factor, so solid buoyancy control matters here. Best conditions fall between July and October.

North Rock sits off New South Wales and draws intermediate divers primarily for its grey nurse sharks, which share the water alongside eagle rays, giant cuttlefish, and nudibranchs. Depths run from the surface to 20 metres, making it manageable for those comfortable with variable conditions. Visibility and current both shift depending on the day, so be prepared to adapt once you're in the water. Mado and striped trumpeter round out the fish life. The site is boat access only, with charters, guided tours, and a dive shop available to support your trip. Best conditions fall between November and June.

The SS Oakland rests at 25 to 27 metres off the New South Wales coast, offering advanced divers a substantial wreck dive with proper overhead environment challenges. This steamship went down in 1903, and over a century of submersion has transformed her iron hull into an artificial reef supporting various reef species. The wreck sits upright and largely intact, though you'll need to carefully plan your penetration routes and manage your gas supply at this depth. Visibility ranges from 7 to 18 metres depending on conditions, giving you decent sight lines for navigation and orientation. Mild currents make the descent manageable, but the depth and overhead environments demand solid buoyancy control and wreck diving experience. The structure's age means you'll encounter weakened sections, so keep your fins up and avoid disturbing sediment. Your bottom time will be limited at this depth, so make your first dive a survey of the exterior before attempting any penetration. Various reef species have colonised the wreck, adding marine life interest to the historical structure.

Little Island is a reef and cave site off New South Wales that works well for beginner divers thanks to its mild current and depths ranging from 1 to 15 metres. Visibility varies considerably, from 2 to 20 metres depending on conditions, so days with good water clarity make a real difference here. The reef supports a range of local species, and the cave adds some structural interest to the dive. Access is by boat only. Be mindful of sharp coral when hovering near the reef, watch for any loose lines or fishing debris that could cause entanglement, and stay aware of your surroundings as sharks are occasionally present.

The SS Macleay sits in 40 to 43 metres off the New South Wales coast, making this a genuine deep dive that demands proper planning and gas management. The freighter went down in 1913, and over a century of submersion has transformed her steel skeleton into a thriving artificial reef. You'll need to factor in decompression stops and stay alert for nitrogen narcosis at depth. Visibility ranges from 5 to 18 metres depending on conditions, while moderate currents add another layer to your dive planning. The wreck attracts an impressive roster of pelagic and reef species. Giant cuttlefish patrol the structure, whilst wobbegong sharks rest in the shadows. Red and blue morwongs cruise the wreckage alongside yellowtail and bream, with schools of pomfreds appearing in the blue. Look for seapike hunting in the water column and Sergeant Bakers perched on the metal. Blue groper, those iconic NSW residents, are regular visitors. This is technical diving territory where experience counts. Your bottom time will be limited, so plan your penetration carefully if entering the wreck. The combination of depth, current and decompression obligations makes the Macleay a site that rewards preparation and respect.

Cabbage Tree Island offers beginner divers a rare chance to encounter grey nurse sharks in comfortable conditions. Located off the New South Wales coast, this boat dive combines several underwater environments in one site, with depths ranging from 4 to 20 metres and visibility between 1 and 15 metres. The gentle currents make it manageable for newer divers building their skills. The main attraction is the resident population of grey nurse sharks, often seen cruising along the wall or resting in gutters. You'll also spot Port Jackson sharks wedged into crevices and wobbegong sharks camouflaged against the reef. The rocky walls host sponge gardens in vibrant colours, while moray eels peer from their holes and rays glide over patches of seagrass. Keep your eyes open for smaller creatures too. Octopuses hide among the rocks, and if you look carefully in darker spots, you might find pineapplefish or the striking donut nembrotha nudibranch. Sea turtles occasionally pass through the area. The site can experience some surge, so maintain good buoyancy control and be mindful of your position relative to the reef. Winter months from May to September offer the best conditions for diving here.

Bennetts Beach is a shore entry snorkelling spot in New South Wales suited to beginners looking to explore calm, shallow waters close to shore. Conditions are generally gentle, though currents can vary, so it pays to check before you get in. Visibility shifts depending on weather and swell, so you may encounter clear water one day and murkier conditions the next. Various reef species inhabit the area, giving newer snorkellers a chance to observe local marine life without venturing deep. Parking is available on site, making access straightforward.

Jimmy's Beach is a gentle shore dive in New South Wales that suits those just getting started underwater. You enter directly from the beach into shallow water ranging from 1 to 5 metres, so there is no need to manage currents or navigate complex entry points. The site combines seagrass beds and reef, giving you two distinct habitats to explore in a single dive. Visibility can range from 1 to 15 metres depending on conditions, with the clearest water typically arriving in the summer months of January through March. Various reef species move through both the reef and seagrass areas, rewarding slow, patient swimmers.
