Dive-site story
Located along the southern tip of the Mornington Peninsula facing Western Port, Flinders Pier provides accessible temperate reef diving under wooden pilings and across adjacent seagrass beds. The site offers reliable encounters with Victoria's marine emblem, the weedy seadragon, navigating dense kelp ribbons and sea grass meadows. Pilings are coated in sponges, ascidians, and kelp, creating shelter for small benthic fishes, nudibranchs, and crustaceans.
Resident populations of camouflaged weedy seadragons hovering among seagrass and kelp fronds
Pier pylons covered in colourful ascidians, encrusting sponges, and bryozoans
Macro photography opportunities featuring diverse nudibranchs, pygmy leatherjackets, and blennies
Occasional sightings of smooth rays, banjo sharks, and schooling calamari squid
