Blackwall Reach

Blackwall Reach is a coastal dive site near Fremantle, Western Australia, known for its shallow, sheltered conditions and diverse seafloor. The site features a gentle slope with Mediterranean-like seagrass beds and patches of reef-grade habitat, making it suitable for beginners and for practice at the end of an open-water course. Depending on tides and clarity, visibility typically ranges from fair to good, with varying currents that require basic awareness. Common encounter include small reef fish, wrasse, and occasional crustaceans; larger pelagics are not guaranteed but can appear in deeper sections. Access is straightforward from Fremantle, with a boat or shore entry depending on conditions. As with many Perth coast sites, plan dives to avoid strong winds and be mindful of protected areas nearby.
