Best for intermediate divers, 1-80m, boat entry, strong current.
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.
