Bridgetown is a town in the South West region of Western Australia, approximately south of Perth on the Blackwood River at the intersection of South Western Highway with Brockman Highway to Nannup and Augusta.
The area was previously known as Geegelup, which was believed to mean "place of gilgies" in the Noongar Aboriginal language, referring to the fresh water crustaceans that live in the area. However, recently discovered research made available through the Bridgetown Tourist Centre suggests the actual meaning of Geegelup may be "place of spears".
In 1857, Edward Godfrey Hester (now honoured in nearby Hester) and John Blechynden settled in the area. In 1861, convicts built the road from Donnybrook into the area.
Bridgetown's name was first proposed by surveyor Thomas Carey in 1868, for two reasons - "as it is at a bridge and the Bridgetown was the first ship to put in at Bunbury for the wool from these districts", and was approved and gazetted on 9 June 1868.
