Flinders Bay is a bay and locality that is immediately south of the townsite of Augusta, Western Australia, and close to the mouth of the Blackwood River and lies to the north east of Cape Leeuwin.
Flinders Bay (34° 21' 00S. 115° 20' 00E)
On Matthew Flinders Terra Australis Sheet 1 1801-1803 the area was originally known as Dangerous Bight. The bay runs from Point Matthew 1.5 km East North East of Cape Leeuwin to Ledge Point some 8 km east. It was named by either James Stirling or Septimus Roe in 1829 or 1830. Matthew Flinders was first in the Bay on 7 December 1801.
The name of the locality of Flinders Bay is tied to the small settlement that had been a whaling and fishing location, as well as the terminus of the Busselton to Flinders Bay Branch Railway railway line (1920s - closed 1957), and the earlier Flinders Bay jetty (1890s). The settlement was in the earlier days considered to be separate from Augusta but now is more or less the southern portion of the larger community.
