Port Davey is an oceanic inlet located in the south west region of Tasmania, Australia.
Port Davey was named in honour of Thomas Davey, a former Governor of Tasmania. Port Davey is contained within the Port Davey/Bathurst Harbour Marine Nature Reserve, the Melaleuca to Birchs Inlet Important Bird Area and the Southwest National Park, part of the Tasmanian Wilderness World Heritage Area. The Toogee name of the port is Poynduc.
Port Davey lies between the Southern Ocean and Bathurst Harbour, which is linked by the Bathurst Channel. The inlet leads north into Payne Bay, fed by the Davey River, with Payne Bay being defined by the features of Davey Head to the west, and Mount Berry to the east. The eastern aspect from Joe Page Bay to Bathurst Harbour is sheltered from the Roaring Forties that buffet the south and west coasts of Tasmania by a narrow part of the inlet that effectively makes the land to the south a peninsula. The north-south ranges on the peninsula’s South West Cape Range and Melaleuca Range lie to the west of the Southwest Conservation Area which is a section of land excluded from the South West National Park that exists between Melaleuca Inlet on the south side of Bathurst Harbour and Cox Bight on the south coast.
It is the penultimate waypoint on the western part of the South Coast Walking Track that is also known as South Coast and Port Davey Tracks.
Port Davey is not populated, but for many years Deny King and family resided at Melaleuca, engaged in alluvial tin mining. Since the death of Deny King in 1991, the family retain a leasehold within the national park and are actively involved in conservation programs but are not permanently resident.
