History
Warnbro was newly created at the 2008 redistribution, but was a smaller version of the former seat of Peel. Peel was held by Labor continuously from its creation in 1989 until its abolition.
Norm Malborough had been first elected in Cockburn in 1986, and moved to Peel in 1989. He held the seat until his resignation under a cloud of scandal in 2006.
In early 2007, the by-election was won by Labor candidate Paul Papalia.
Papalia won the new seat of Warnbro in 2008, and was re-elected in 2013 and 2017.
