Meet the site
Guichen Bay is Robe's sheltered harbour – the reason the town grew there in the 1840s – and the Marine Life Network describes it as a safe harbour with clear water, white sand and large seagrass meadows full of small marine life. It is the easy, protected option near Robe when the open coast at Cape Dombey is rough.
This is a shallow, gentle seagrass and sand dive rather than a reef dive. The meadows of Posidonia and Amphibolis are nurseries for juvenile fish, and patient divers and snorkellers find pipefish, small cuttlefish, hermit crabs, sea stars, flathead and stingarees on the sand edges, with rays and schools of mullet and salmon crossing the open areas. The jetty adds structure: pylons with sponges and algae, and squid attracted by the lights at night. Visibility is often good over the white sand, and the shallow depth gives long, warm (by local standards) dives in summer.
It is not a destination dive, and published diver information is scant, but it is useful: a checkout or refresher site, a snorkel for families, and a night-dive option in a town that otherwise depends on calm seas. Robe itself is a pleasant base with accommodation, restaurants and historic buildings, and the bay's lee means you can usually get wet here on a Limestone Coast trip when everything else is closed. It suits beginners, snorkellers and macro enthusiasts. Bring your own cylinders: the nearest fills are in Mount Gambier, 130 km away, so a Robe stay needs planning around air.
