Dive-site story
A historic military structure inside the entrance of Port Phillip Bay, Chinaman's Hat serves as a haul-out site for Australian fur seals. Below the waterline, marine growth and kelp patches scatter across the sandy seabed surrounding the pylons. Juvenile and adult seals circle divers in the shallows before darting surface-ward. Strong tidal flow through the nearby shipping channel demands strict entry timing.
