The Hotham Valley railway (operated by WAGR) was opened from Pinjarra to Dwellingup in 1910 to access the jarrah and marri timber in the area.

In the year of 1926 alone, the Banksiadale mill produced 185,000 sleepers, and 6,347 other loads, of which the WAGR utilised a little more than 50%, the balance being sold or stacked.

[3] By 1946, the local timber had been exhausted and WAGR obtained another concession at Asquith Block, 30 km east of Harvey upstream from Nanga Brook, which was being worked by Millar Brothers.

[4] The Dwellingup fires in January and February 1961 devastated the countryside but the Banksiadale townsite and timber mill escaped damage.

The mill only, was burnt down in 1963 and was not rebuilt as it was on land destined to be flooded when the South Dandalup Dam was constructed.
