Townsite and locality share identical borders..[3][4] The town of Broomehill (originally Broome Hill) owes its creation to the Great Southern Railway, which was completed in 1889.

Broomehill is named after Sir Frederick Napier Broome (1842–1896) who was then the Governor of Western Australia.

[5] In the same year Patrick Garrity purchased two lots facing Jasper Street and built a galvanised iron hotel.

[6] The townsite was gazetted by the Western Australian Land Company in 1890, which was recognised by the state government in 1897.

[7] A group of settlers from the now extinct town of Eticup moved to the present site of Broomehill to help establish a township after the construction of the railway was completed.

[22] The 700 kilometres (435 mi) track was established in 1893 by the pioneer John Holland through the bush via Newdegate to the goldfields at Coolgardie.
