Madeley is a suburb of Perth, the capital city of Western Australia 20 kilometres (12 mi) north of Perth's central business district. Its local government area is the City of Wanneroo. Previously part of Landsdale, much of the suburb was rural in character until the 1990s, with market gardening a common activity. From 2001 onwards, extensive property development resulted in massive population growth, with the Property Investor Magazine of December 2007 estimating a growth rate of 33.3% per year.
Historically, the area was officially unnamed and residents noted their addresses as Wanneroo until the locality of Landsdale was gazetted in 1980, extending from Wanneroo Road to Alexander Drive.
In May–June 1996, with the creation of the East Wanneroo Development Area, Cell 6 was identified as a high priority for development, and was divided into western and eastern sections corresponding to modern Madeley and Darch respectively. On 10 September 1997, the City of Wanneroo resolved to name the locality Kingsway after the main east-west road running through it, and to name the area east of the proposed Skeit Road as Madeley. The Geographic Names Committee (GNC) approved Madeley, but rejected Kingsway as being too similar to Kingsley. The City, by this stage administered by commissioners, met on 17 February 1998, and decided to use Madeley for the western area, and to honour another settler family in naming the eastern section Darch. On 5 March 1998, the name Darch was approved by the GNC, formally releasing the name Madeley. The City applied for the name Madeley on 28 April 1998, and it was granted at the GNC's meeting on 19 June 1998.
As a fairly new suburb, Madeley as yet has no clear political direction, with the Liberal party winning more than half the booth vote at both the 2004 and 2007 federal elections, but the Australian Labor Party doing the same at the 2005 state election. An emerging trend is a higher vote than the regional average for the Christian Democratic Party and Family First. The following figures are for booths in neighbouring Darch which serve both suburbs:
