Blue Lagoon sits within the remote Clerke Reef system, offering boat-access diving across a reef that extends from a manageable 8 metres down into deeper water at 30 metres. Visibility here is exceptional, regularly reaching 20 to 50 metres in the clear offshore water, which makes reading the reef structure and tracking movement in the water column straightforward. Moderate currents run through the site, making drift diving the practical approach rather than an optional extra. Those currents also do the work of bringing various reef species past you. Sharks are a genuine presence, so maintain awareness throughout your dive.

Roe Reef is a serious site that demands respect and rewards experience. The wall drops hard into deep diving territory, with canyons and caverns breaking up the topography and strong currents that can run without much warning. Visibility routinely stretches from 25 to 60 metres, which means you see the pelagics coming from a long way out. Hammerhead sharks and manta rays work the blue water beyond the wall edge, while giant potato cod and Maori wrasse hold close to the structure. Wobbegong and white-tip reef sharks patrol the caverns. Trevally, mackerel and tuna move through in schools when the current picks up. Sea turtles appear throughout. Best conditions run from September through December.

Supermarket earns its name from the sheer concentration of apex predators that patrol this wall and reef system off Western Australia. Strong currents are a constant here, pushing down to 40 metres against a wall with visibility that can stretch to 60 metres on good days. That current is your friend and your challenge: it draws in grey reef sharks, whitetip reef sharks, silvertip sharks, and occasionally hammerheads, alongside giant potato cod and Maori wrasse. Manta rays, sea turtles, dolphins, and humpback whales round out an already serious pelagic cast. This is boat-access only, and you need solid drift diving skills before committing to it.

Outer Wall is a deep-water site that demands respect and rewards experience. The wall drops well into the 40-metre range, where gorgonian fans and soft corals line the structure alongside plate corals in shallower sections. Visibility can swing dramatically, anywhere from near-zero to a remarkable 45 metres, so conditions vary considerably between visits. Strong currents run regularly here, which is precisely what draws greater hammerheads, sharks, and bluefin trevally to work the wall. Sea turtles and Moorish idols round out the regular sightings. Boat access only, and this is firmly advanced territory given the depth and current exposure.

Mermaid Reef sits in one of Australia's most remote diving locations, roughly 300 kilometres off the Kimberley coast. This offshore reef system drops from shallow coral gardens at 1 metre down vertical walls to 40 metres, creating drift diving conditions that attract serious pelagic action. Strong currents are the norm here, which means you'll need solid buoyancy control and drift diving experience before jumping in. The current brings the crowds. Potato cod cruise the walls, often approaching within touching distance, while maori wrasse patrol the deeper sections. Dogtooth tuna flash past in the blue, and sharks are regular visitors. During migration season, humpback whales pass through the area, and manta rays glide along the reef edge. Sailfish occasionally make appearances in the deeper water. The reef itself hosts green turtles, giant clams wedged into coral formations, and gorgonian fans that bend with the current. Visibility ranges from zero to 60 metres depending on conditions and current strength. The deep wall and strong flow make this a genuine intermediate to advanced site. Most diving here involves live-aboard operations, as the reef's isolation means no shore access or day trip options.

The Lively Shipwreck sits off Western Australia's coast, combining a substantial wreck structure with surrounding reef across a depth range of 0 to 40 metres. Strong currents run through regularly, which demands solid buoyancy control and dive planning, but those same currents drive the pelagic activity that makes this site worth the effort. Hammerhead sharks, grey reef sharks, and manta rays work the water column, while potato cod and moray eels hold territory closer to the wreck. Giant clams and sea turtles round out the reef life. Visibility can reach up to 60 metres in ideal conditions. October through December offers the most reliable conditions and the best chance of encountering humpback whales and sailfish in open water.

Cod Hole earns its name from the giant potato cod that patrol this Western Australian reef with remarkable confidence around divers. Visibility runs from 25 to 60 metres in these clear waters, meaning you'll often spot the big animals well before they reach you. The reef drops to 30 metres, though most of the action happens in the shallower sections where Maori wrasse, turtles, and schools of trevally, mackerel, and tuna move through. Strong currents are the main variable here, so dive timing matters. Between September and November, hammerhead sharks, reef sharks, manta rays, and even humpback whales become realistic sightings. Boat charter access only.

V in the Wall is a dramatic wall dive off Western Australia that plunges from 50 metres into genuinely deep water, reaching 440 metres at its full extent. Visibility runs 20 to 60 metres, so you can appreciate the full scale of the structure before you even reach depth. Strong currents are the norm here, which is precisely what draws the pelagics: dogtooth tuna, Spanish mackerel, hammerhead sharks, and manta rays all use this wall as a hunting and feeding corridor. Resident species including giant potato cod, Maori wrasse, humphead parrotfish, coral trout, clownfish, and green turtles work the shallower reef sections. Plan your dive around current, not just depth.
