History

Armadale was created at the 1982 redistribution out of parts of the seats of Dale and Gosnells. It was first contested in the 1983 election, in which Labor member Bob Pearce, who had previously represented Gosnells, was successful. The seat has been regarded as very safe for the Labor Party since its creation, and at the 2001 election, the Liberal Party did not field a candidate for the seat. It was held from 1996 until 2010 by Alannah MacTiernan, the Minister for Planning and Infrastructure in the Gallop and Carpenter governments.

On 25 June 2010, MacTiernan resigned from the Western Australian Legislative Assembly to run for the federal seat of Canning. A by-election occurred on 2 October 2010 and Labor candidate Tony Buti was elected. Buti was re-elected at the state elections in 2013 and 2017. In the latter election, he increased his majority to 25.2 percent, making Armadale the safest seat in the legislature.

Geography

As of 2025 Armadale is based mostly around the built-up Armadale suburban area, with Tonkin Highway forming a boundary to the northwest. The boundaries contain the suburbs of Armadale, Camillo, Champion Lakes, Kelmscott, Mount Nasura and Seville Grove as well as parts of Mount Richon.

The 2007 redistribution, which took effect at the 2008 election, resulted in the seat losing eastern Kelmscott as well as Wungong and Forrestdale. At the time Armadale was bounded by the Tonkin Highway to the northwest, the Canning River to the northeast, and the limits of the Armadale suburban area to the south and southeast. Its boundaries included the suburbs of Armadale, Brookdale, Champion Lakes, Hilbert, Mount Nasura, Mount Richon, Seville Grove and Camillo, as well as Kelmscott west of the Canning River.

Armadale was left unchanged until the 2023 redistribution, where population growth in the south-western part of the seat accelerated to the point that a new seat was created in the form of Oakford. The suburbs of Brookdale, Haynes and Hilbert were transferred to the new seat while regaining the part of Kelmscott east of the Canning River from Darling Range.
