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.

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.

Northern Wall is a serious dive site where a reef top drops away into an 80-metre wall, giving you that satisfying sense of open water beneath you as you work the edge. Visibility swings between 10 and 50 metres depending on conditions, so on a clear day the wall face opens up dramatically. Moderate currents are the norm, which makes this a natural drift dive along the structure, but currents can run stronger than expected so stay aware throughout. Various reef species populate the wall and surrounding reef. Boat traffic is active in the area, and sharks are a genuine presence, so a surface marker buoy on ascent is non-negotiable. October and November bring the most reliable conditions.

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.

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.

Clerke Reef sits in the Rowley Shoals, roughly 300 kilometres west of Broome, and delivers some of Western Australia's most dramatic wall diving. You'll descend along near-vertical coral faces that drop from the shallows to 40 metres, with strong currents bringing in pelagic action throughout the dive. The site works well as a drift dive, letting you glide along the wall whilst scanning the blue water for passing sailfish, tuna, and schools of mackerel. Grey reef sharks and whitetip reef sharks patrol the deeper sections, whilst giant potato cod cruise the mid-depths with surprising curiosity. Maori wrasse lumber through the reef structure, and sea turtles appear regularly on the shallower sections. Visibility ranges dramatically from near-zero to 50 metres depending on conditions and current strength, so prepare for anything. The caverns along the wall offer shelter from the current and harbour nudibranchs in the quieter pockets. You'll occasionally spot dolphins in the surrounding waters during surface intervals. The strong currents demand solid buoyancy control and drift diving experience. This is boat-only access with charter operations running from Broome during the winter months, typically August through October when conditions are most reliable.
