History
The electorate of Rockingham has existed since 1974, and has always been a Labor seat.
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 five 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.
McGowan stepped down as premier and as an MP in 2023, and the subsequent by-election was won by Labor candidate Magenta Marshall.
- Hayley Edwards (Liberal)
