Mermaid Reef is a remote offshore reef system located 260 kilometres from the coast. The topography features shallow coral gardens starting at 1 metre that transition into vertical walls dropping to 80 metres. The site is defined by strong tidal currents, making it suitable for drift diving. Due to the isolation of the Rowley Shoals, access is exclusively via live-aboard vessels. Divers should be prepared for deep water and significant current flows. Visibility varies significantly, ranging from near zero to 60 metres depending on tidal conditions. The site requires intermediate to advanced diving skills and self-sufficient planning.

Cod Hole is a reef site located at Mermaid Reef, accessible only by boat. The topography features outer reef walls dropping to 30 metres, with an average depth of 18 metres. Divers experience strong tidal currents, which facilitate drift diving, though these currents can be variable and require careful planning around slack water. Visibility is high, ranging from 25 to 60 metres. The site is suitable for intermediate divers due to the current and depth. Facilities available include boat charters, guided tours, and air fills. Night diving is permitted at this location.

V in the Wall is a dramatic wall dive located at Mermaid Reef, Western Australia. The site features a steep wall that plunges from 8 metres to depths of 40 metres and beyond. Due to its location 300 kilometres from shore, this site is accessible only by boat. Divers encounter strong currents driven by tidal ranges of up to 5 metres, which funnel through the area. Visibility is excellent, ranging from 20 to 60 metres. Given the deep water and powerful currents, this site is suitable only for advanced divers. Night diving is available, and local facilities include air fills, guided tours, and gear storage.

Northern Wall at Mermaid Reef is a drift dive featuring a reef top that drops into a wall reaching 80 metres. Divers experience moderate currents along the structure, though conditions can shift quickly. Visibility ranges from 10 to 50 metres. Due to the depth and potential for strong currents, this site is suited for intermediate divers. Boat access is required, and surface marker buoys are essential for safety during ascents due to active boat traffic. Localised upwellings of cool water support a variety of reef fish and invertebrates. Divers should plan their entry around slack water and maintain close proximity to their guide throughout the dive.

Blue Lagoon is a remote reef site within the Clerke Reef system, accessible only by boat. The topography features a reef structure that slopes from 8 metres down to 30 metres, with an average depth of 10 metres. Divers experience moderate currents, making this an intermediate drift dive. Visibility is high, typically ranging between 20 and 50 metres. Due to the offshore location and the presence of sharks, divers must maintain constant awareness and coordinate closely with their boat skipper for entry and exit. This site is suitable for both diving and snorkelling, provided participants are comfortable with drift conditions and boat-based operations.

Supermarket is a remote reef and wall system located in the Rowley Shoals, accessible only by boat. The site is defined by its strong tidal currents, which facilitate high-speed drift dives along the wall. Depths range from 5 to 40 metres, with visibility frequently reaching between 15 and 60 metres. Due to the significant tidal flows and depth, this site is strictly for advanced divers. Water temperatures remain consistent, typically between 26 and 29 degrees Celsius. Divers must coordinate their drift lines with the boat crew prior to entry, as the currents are the primary environmental factor at this location.

Clerke Reef is a remote site in the Rowley Shoals, featuring dramatic near-vertical walls that drop from the shallows to 40 metres. The topography includes caverns that provide shelter from strong tidal currents, which are a defining feature of the area. Divers and snorkellers experience high-speed drift dives along the reef face. Visibility is highly variable, ranging from near-zero to 50 metres. Due to the strong currents and remote location, this site is suited for intermediate divers with solid buoyancy control. Access is by boat only, with charters typically operating from Broome. The habitat supports a variety of reef fish and invertebrates throughout the wall and cavern structures.
