Onslow is an eighty kilometre return diversion of highway one. But you can be sure it is worth it. This great little town on the coast that is rich with very interesting history. Onslow is also a very friendly spot.
Onslow was originally founded in 1883 as a port at the mouth of the Ashburton River for exporting product, namely wool from the Pilbara. It was named after the then Chief Justice Alexander Onslow of Western Australia Sir (1842–1908).
The new location for Onslow proved rather better protected from the cyclones' violence. However a major long-term drought between 1935 and 1941, during which time only one cyclone hit (in April 1937) and did not produce rain on the inland sheep stations, led to a decline in Onslow's fortunes.
During WW11 the town was bombed by the Japanese.
