It was originally a railway siding named Jardanup, which had been established in 1912 during the construction of the Bridgetown to Wilgarup railway line. Jardanup was the terminus built to service the No. 1 state saw mill, also built in 1912.
In 1920 the railway line spread during the visit of Edward Prince of Wales, (the future King Edward VIII) derailing the royal train. In most reports the location was identified as "ten miles from Bridgetown".
