Stoney Creek is a deep wall dive in New South Wales that earns its advanced rating on every front. The site drops from 39 to 56 metres, putting you firmly in decompression territory, and the strong currents here are not negotiable. Plan your bottom time carefully before you descend. Visibility of 25 to 35 metres rewards the effort, giving you long sightlines along the wall face where sea whips, gorgonians, sponges, and sea squirts colonise the structure in dense filter-feeding communities. Nitrogen narcosis is a genuine consideration at these depths, so know your limits and dive with a buddy you trust.

Green Patch Beach is a gentle shore entry site combining reef and seagrass habitat in easy shallow waters, reaching just 10 metres at its deepest. Visibility runs from 5 to 10 metres, and the mild current makes this a comfortable choice for beginners building confidence underwater. The seagrass beds are worth slowing down for, as they shelter seahorses, pipefish, and squid. On the reef, look for blue groper, wrasse, and leatherjacket moving between the rocks, while Port Jackson sharks and fiddler rays often rest on the sandy bottom. Octopus, Australian giant cuttlefish, and the occasional seagrass seahorse round out the highlights. Watch the surf on entry and exit.

Hole in the Wall drops you into a wall dive in deeper water, running to 30 metres where nitrogen narcosis becomes a genuine consideration for anyone pushing the bottom. Visibility can reach 30 metres in the right conditions, though the site-listed range is wide, so check recent reports before committing. Current stays mild, which helps when you're working the wall methodically. This is grey nurse shark and wobbegong territory, and the site also draws weedy sea dragons, giant cuttlefish, octopus, Port Jackson sharks, nudibranchs, and seals. Boat traffic is an active hazard on ascent, so deploy your DSMB and stay alert during the safety stop.

Smugglers Cave delivers a serious dive profile that pushes into technical territory, with depths reaching 33 metres through an overhead environment that demands solid skills and composure. Variable currents and surge add complexity to the navigation, whilst reduced visibility in sections keeps you focused on your gauges and buddy position. The marine life compensates for the demanding conditions. Grey nurse sharks patrol the deeper sections, their distinctive profiles unmistakable even in limited vis. Port Jackson sharks rest in crevices, whilst eastern blue devilfish lurk amongst the rocks. Seals occasionally investigate divers, bringing playful energy to the darker corners of the cave system. Bottlenose dolphins pass by in open water, and if conditions align, you might spot weedy sea-dragons drifting in the kelp or giant cuttlefish displaying their remarkable colour changes. This is boat access only, launching from facilities that include a dive shop and charter services. The site dives year-round, though conditions vary significantly with swell and current. Your advanced certification and deep diving experience are not just recommended but essential here. Plan your gas consumption carefully, account for the overhead environment, and respect the depth limits. The cave rewards technical competence with encounters you will not find on easier sites.

Murrays Beach is a calm, shallow shore dive well suited to beginners looking to build confidence in the water. The seagrass beds and surrounding reef provide habitat for some genuinely rewarding encounters, including weedy sea-dragons, octopus, and small stingrays resting on the sand. Blue gropers and eastern blue devilfish are common reef residents, and squid and rockfish appear regularly. Visibility can vary, so pick a settled day for the clearest water. Mild current is typical, though be aware of surge and surf near the entry point. Dolphins pass through on occasion.

Hyams Beach offers a sheltered reef dive in shallow to moderate depths of 1 to 12 metres, making it a comfortable choice for beginners. Visibility runs from 2 to 10 metres depending on conditions, and the current is generally mild. The seafloor transitions through seagrass beds and sponge gardens where you can find weedy seadragons, octopus, and fiddler rays resting on the sand. Eastern blue groper, leatherjackets, and Australian giant cuttlefish are regularly spotted along the reef, and Port Jackson sharks shelter close to the bottom. Check the surf and watch for rip currents before entering from shore.

Nursery at Bowen Island offers beginner divers an unforgettable introduction to Australia's most famous shark encounter. This boat-accessible site sits at depths between 3 and 16 metres, making it comfortable for newer divers while delivering spectacular marine life. The real draw here is the chance to observe Grey Nurse Sharks in their natural habitat, often joined by Port Jackson Sharks and Wobbegong sharks resting on the sandy bottom. Visibility ranges from 10 to 25 metres, giving you excellent sightlines to appreciate these gentle giants despite their intimidating appearance. The mild current keeps conditions manageable, though you may notice some surge near the surface. Between the sharks, you'll find Eastern Blue Devils darting between rocks, seahorses clinging to growth, and the occasional cuttlefish or octopus displaying remarkable colour changes. Rays glide past while yellowtail and seapike patrol the mid-water. The site works best during the cooler months from April through September when Grey Nurse Sharks congregate here. Full facilities are available including boat charters, dive shop services, equipment rental, air fills, and parking at the departure point. While sharks might seem daunting, these species are docile and more interested in their own business than you. Just maintain neutral buoyancy and enjoy the show.

The Wall is a serious dive that rewards experienced divers with a dramatic vertical drop-off plunging well past 30 metres, where variable currents keep conditions unpredictable and nitrogen narcosis becomes a real consideration. Visibility swings between 10 and 30 metres depending on conditions, and the cave and overhead sections demand solid buoyancy control and a clear head. Grey nurse sharks and wobbegong sharks are regular residents along the wall face, while giant cuttlefish, octopus, and nudibranch work the reef structure at shallower depths. Keep an eye out for weedy sea dragons and pipefish in calmer pockets, and Port Jackson sharks resting on ledges.
