South Australia · 35 sites
The Fleurieu is where you go to see a leafy seadragon. Rapid Bay Jetty is the most reliable site anywhere, and Second Valley, the Bluff at Victor Harbor and Port Noarlunga are close behind. The ex-HMAS Hobart, a 133 m destroyer scuttled off Yankalilla in 2002, is the region's flagship boat dive, and the granite coves of Second Valley and Carrickalinga are easy shore dives.
Conditions outlook · Late September – October 2026
