from the ship in Ashburton Roads to the jetty, then by horse-tram from the jetty across of marshland inland to the town. 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.
On 15 May 1943, Onslow became the most southerly town in Australia to be bombed by Imperial Japan in World War II, when a single plane bombed the airfield. However, there was no damage or casualties.[
Since the war, the declining purchasing power of wool has, despite consistently good rainfall on the inland sheep stations since the late 1960s, led to a change in focus of Onslow's economy from wool to tourism. It is an access point for Coral Coast activities, such as ]scuba diving

During Onslow's long history, the town has gone through the extremes of heatwaves, heavy rains and cyclones. 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.

Cyclones
Numerous cyclones have impacted Onslow over the years, the first recorded by white colonists was in 1880. On 28 March 1934, a severe cyclone hit the town, with the new jetty nearly destroyed. All the buildings suffered damage, with some destroyed.[ Another severe cyclone crossed the coast at Onslow on 7 February 1963, damaging nearly every building in town. Destructive wind gusts of were recorded during the cyclone, which bent telephone poles, leaving them parallel with the ground.][ On 19 February 1975, Severe Tropical Cyclone Trixie crossed the coast near Onslow, with the cyclone's centre passing directly over nearby Mardie.][ A wind gust of were recorded at Onslow, whilst wind gusts of at Mardie (This was the limit of the recorder, so the gusts at Mardie may have been higher).] At the time, the wind gust recorded at Onslow was the highest recorded in Australia.
