The original inhabitants of the area are by the Bungandidj Aboriginal people, who refer to it as Ngaranga, possibly meaning "noisy" or "caves".[10] Their oral history records that dry land previously extended southwards from the current coastline, before it was flooded by rising sea levels.[9]: 23
In the 1880s, it was one of Australia's busiest ports, shipping large quantities of wheat and wool to Europe. The port was, however, exposed to the weather and the site of many shipwrecks.[14] Across the border in Portland, Victoria, 85 km southeast, is a much more sheltered port.
The town of Port MacDonnell is set on flat swampy land in a bay between rocky capes of spectacular wave eroded formations the most spectacular being those to the near west at Cape Northumberland. The harbour is formed by a large artificially constructed rock breakwater, while the coastline consists of sandy beaches, with rock outcrops providing shelter to the port from the rough seas. The rocks provides substantial habitat for the southern rock lobster, the fishing and processing of which is the town's main industry and colonies of little penguin.
Lighthouse
Cape Northumberland has a prominent lighthouse which dates to 1882. An earlier 1858 lighthouse was the first in South Australia, but was demolished after it was in danger of collapse. A monument marks its site.[18]
