Cause of by-election
Sitting Labor MP Mark McGowan is retiring after six years as Premier of Western Australia.
Margin – ALP 37.7%
Southern coastal fringe of Perth. Rockingham covers the suburbs of Rockingham, Shoalwater, Safety Bay, Hillman and part of Cooloongup and Waikiki, in the north-western corner of the Rockingham council area.
Labor’s Mike Barnett won Rockingham in 1974. Barnett served as a shadow minister from 1977 until 1983, and as Speaker from 1986 until 1993. He retired in 1996.
Rockingham was won in 1996 by Labor’s Mark McGowan. McGowan has been re-elected in Rockingham six times. He joined the ministry after the 2005 election, and became Labor leader in 2012.
McGowan led Labor to the 2013 and 2017 elections, winning government in a landslide in 2017. McGowan led Labor to a second term in 2021, winning one of the largest landslides in Australian political history.

- Madeleine De Jong (Greens)
- Clive Galletly (Independent)

- Mike Crichton (Australian Christians)

Rockingham is held by one of the largest margins ever seen. It seems likely that there will be a substantial swing back to a more normal margin, but it’s hard to see Labor losing this seat, even in McGowan’s absence.
