Settlement history

European settlement of the Serpentine Jarrahdale area dates from the 1830s, with land used mainly for farming and timber getting. Population was minimal until the late 1800s when many townships were established, aided by the opening of timber mills in the 1870s and the construction of the Perth to Bunbury railway line in 1893. Significant residential development did not occur until the 1980s, with the population of the Shire increasing from about 5,000 in 1981 to 8,000 in 1991. Rapid growth continued from the 1990s, with the population rising to over 17,000 in 2011, the most rapid growth being between 2006 and 2011. Population growth is expected to continue, particularly in the northern areas, as Perth expands southwards.
