Doubtful Islands - WA

Doubtful Islands are a group of three small islands located approximately 3 kilometres offshore of Point Hood and approximately 20 kilometres east of Bremer Bay in Western Australia.
The islands occupy an area of approximately 170 hectares and are found at the southern end of Doubtful Islands Bay in the Great Southern region.
The islands were named by George Vancouver in 1791, the name derived from his being doubtful that these were islands at all. Matthew Flinders confirmed that the group were islands in 1802 while on expedition in the area.
Two whaling stations were established around the islands in 1837, one by George Cheyne and the other by Thomas Booker Sherratt
