Corner Inlet, Marine inlet and Ramsar site in Victoria, Australia.

Corner Inlet is a marine inlet with extensive wetlands along Victoria's southeastern coast, featuring tidal creeks, mangroves, seagrass meadows, mudflats, and saltmarshes. The site encompasses a vast expanse of interconnected habitats that support diverse wildlife populations.

The designation as a Ramsar site in 1982 marked its international recognition as a wetland of global importance for waterbird conservation. This formal status reflected the inlet's critical role in protecting migratory and resident bird populations.

Corner Inlet lies within the traditional lands of the Brataolong clan of the Gunai nation. European settlers arrived in the early 1840s and set up agricultural, mining and forestry enterprises, and commercial fishing took hold in the 1860s. The surrounding forest was mostly cleared, and the inlet is now used for recreational boating and fishing.

Access to the inlet works best for bird watchers and nature explorers, with conditions varying by tidal patterns and season. Visitors should come prepared for the coastal environment and bring proper gear for outdoor activities.

Corner Inlet contains the most extensive intertidal mudflats in Victoria, and BirdLife International recognised about 720 square kilometres of land and water as an Important Bird Area. More than 1% of the world populations of chestnut teal, Far Eastern curlew, red-necked stint, pied and sooty oystercatchers and hooded plover occur there, and the critically endangered orange-bellied parrot has occasionally been seen.
