About this spot

Ammunition Jetty sits near Coogee in Perth, Western Australia, serving divers year-round without seasonal closures or permit restrictions. The site sits outside a marine protected area, making access straightforward for recreational divers. Water conditions remain stable throughout the year, with documented coral showing no bleaching stress—a sign of good reef health. Twelve species observations have been logged at the site, giving divers a solid sense of what marine life to expect. The jetty structure itself creates habitat for fish, crustaceans, and other organisms adapted to temperate Australian waters. Local dive guides and community members have posted three videos documenting the site, which provides useful reference material before your visit. The site works well for divers planning a Perth-based dive trip without worrying about seasonal windows or complex permit requirements. Depths and visibility vary with conditions, so checking local dive shop reports before heading out is smart practice. The absence of coral bleaching stress indicates the reef environment remains resilient, which bodes well for consistent marine life encounters.
