Serpentine-Jarrahdale was created for the
2005 state election. In territory, the district replaced much of the abolished
Roleystone. However, only 41% of its voters came from Roleystone. The other 59% were previously part of the district of
Southern River, which was radically redrawn. Serpentine-Jarrahdale was abolished ahead of the
2008 state election. Much of the district's territory went to the radically redrawn
Darling Range, whilst its eastern sections were added to
Southern River and formed part of new seats of
Jandakot and
Kwinana. The district's representative for its sole term was Liberal MP
Tony Simpson. Simpson contested and won Darling Range at the 2008 election. ==Members for Serpentine-Jarrahdale==
