Cleaner Station South Solitary Island lives up to its name as a marine congregation point where larger species arrive for their grooming sessions. This boat-accessed reef dive sits at 10 to 20 metres, where moderate currents bring nutrients that sustain the cleaning stations and attract pelagic visitors. Visibility ranges from 10 to 30 metres, giving you ample warning of approaching grey nurse sharks and manta rays cruising through the blue. The site's reef structure includes caves worth exploring between drift segments, where you might spot ornate ghostpipefish hiding among soft corals or anglerfish camouflaged on rocky surfaces. Loggerhead turtles patrol the area, whilst leopard sharks rest on sandy patches between the reef. Schools of kingfish hunt overhead, and you'll encounter resident black cod and blue groper around the cave entrances. Giant cuttlefish appear during their aggregation periods, adding another layer to an already diverse site. The moderate current requires decent buoyancy control and awareness of your surroundings. Keep an eye on boat traffic at the surface during your ascent, and be prepared for the current to pick up mid-dive. The combination of cleaning station activity and varied terrain makes this a rewarding site for intermediate divers looking to expand their logbook with quality marine encounters.

South Boulder at South Solitary Island delivers some of the Solitary Islands' most dramatic diving, with a steep wall plunging from 10 to 30 metres into deep blue water. The moderate current brings excellent visibility, typically ranging from 8 to 35 metres, and carries nutrients that attract impressive pelagic visitors. Grey nurse sharks congregate here seasonally, often hovering in the gutters and caves along the wall, whilst manta rays and eagle rays cruise past in the blue. The site sits where tropical and temperate currents meet, creating an unusual mix of marine life. You'll find leopard sharks resting on ledges alongside wobbegongs, whilst blue groper patrol the reef and black cod hide in crevices. Giant cuttlefish appear during breeding season, and loggerhead turtles are regular visitors. Clownfish dart among anemones in the shallows. The current makes this a natural drift dive, so you'll cover good ground along the wall without much effort. Boat access only, with several operators running trips from Coffs Harbour. The site's accessible year round, though winter months often bring the clearest water and best shark encounters.

Northern Gutters carves a dramatic channel through the reef system on South West Solitary Island's northern face, creating natural swim-throughs between 10 and 30 metres that are particularly good for drift diving. Moderate current flows through the gutters year-round, bringing in grey nurse sharks during their aggregation season and manta rays when plankton blooms attract them to the area. The canyon walls host resident blue groper and kingfish, while leopard sharks rest in sandy patches between the reef structures. Visibility ranges from 10 to 35 metres depending on conditions, with clearer water typically following offshore winds. You'll find giant cuttlefish hunting around the reef edges, black cod tucked into ledges, and the occasional loggerhead turtle cruising past. The gutters themselves act as natural highways for marine life moving between deeper and shallower sections of the reef. Clownfish occupy anemones in the protected areas, and nudibranchs appear on the walls throughout the year. This is a boat-only site with active commercial and charter traffic, so surface awareness matters. The combination of depth, current and shark activity makes this better suited to divers comfortable managing multiple environmental factors simultaneously.

Plate Coral South West sits off Solitary Island, offering an accessible boat dive where you'll drop into water ranging from 5 to 16 metres deep. The site gets its name from the distinctive plate coral formations that characterise the reef, creating shelter for an impressive variety of marine life. You'll likely spot green turtles cruising the reef, and if you're lucky, loggerhead turtles make appearances too. The rocky structure attracts blue groper, wobbegong sharks resting in crevices, and anemone fish darting among their hosts. Keep an eye out for painted crayfish tucked into the reef, alongside nudibranchs in various colours. Pelagic visitors like kingfish and mackerel patrol the blue when conditions are right, whilst cuttlefish hover mid-water. Visibility ranges from 8 to 35 metres depending on conditions. The moderate current keeps the reef healthy but requires some attention to buoyancy and navigation. Be aware of surge near the reef structure and watch for boat traffic at the surface. The site's accessible depths and varied marine life make it ideal for building your experience, though the current means you'll want to stay close to your buddy and dive guide.

Emerald Beach Rock Pools offer a sheltered, shallow snorkelling experience directly from shore in New South Wales. The calm, protected waters make this a friendly introduction to exploring marine life without needing a boat or advanced skills. Visibility varies depending on conditions, so calmer days reward you with clearer water. Keep an eye on the sandy bottom and rocky edges where flathead, stingray, and sand whiting tend to sit still or move slowly. Australian salmon, sea mullet, tailor, and yellowfin bream are also common visitors. Be aware that moderate currents and rip currents exist outside the protected pools, so stay within the calmer sections near the rocks.

Split Solitary Island sits off the New South Wales coast and offers beginner divers a genuine reef experience from a boat entry. The site runs from shallow reef terrain down to 21 metres in its deeper sections, so you can comfortably explore at 10 metres or so while more confident beginners push a little deeper with a guide. Visibility ranges from 5 to 15 metres depending on conditions, and the current stays mild, which makes it far easier to move around without fighting the water. The reef supports a variety of local reef species, giving you plenty to look at as you get comfortable underwater.

Coral Gardens sits off Split Solitary Island, where a healthy reef slopes down to a dramatic drop-off into deeper water. The site runs from 5 to 18 metres, giving you plenty of time to explore without pushing your bottom time. Visibility ranges from 10 to 30 metres, though moderate currents can stir things up on bigger tide swings. The reef here lives up to its name. Hard and soft corals compete for space across the reef slope, creating colourful terrain that attracts a solid variety of fish life. Blue devil fish dart between coral heads whilst red morwong hover in the mid-water. Wobbegong sharks rest in crevices during the day, and moray eels peer out from their holes. If you're patient, you'll spot banded coral shrimp cleaning stations and the occasional egg cowrie tucked against the coral. Turtles cruise through regularly, and nudibranchs appear if you slow down and look closely. The current demands attention, particularly around the drop-off where it can pick up strength. Keep an eye on your position and air consumption. Boat traffic is active in this area, so surface with your SMB and stay close to your group. This is a boat-only site with good facilities back at the marina, including equipment rental and air fills available year-round.

Woolgoolga Headland is a gentle shore entry site suited to newer snorkellers and divers wanting to explore intertidal and shallow reef life. The waters here are calm and shallow, though visibility can vary depending on swell and recent rainfall, so picking a settled day makes a real difference.
