This led the state government in 1923 to develop a new town and jetty north-east at Beadon Point. The new townsite was gazetted on 10 January 1924, and the residents of Old Onslow moved across in 1925. The new location for Onslow's jetty was better protected from storm damage with the townsite more conveniently located on the coast.

For example, in 1912, Onslow received only of rainfall and during 1935-36 combined only fell. While in 1961 a record was recorded, most of which fell between late January and early March, a result of three cyclone impacts within five weeks. These cyclones brought heavy rain and destructive winds to Onslow, resulting in flooding and damage to buildings. 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.
