Incumbent MP
Alex Dighton, since 2024.
Geography
Southern Adelaide. The seat covers Hallett Cove, Sheidow Park, Trott Park, Seaview Downs, Seacliff and South Brighton.
History
Black was created as a new seat in 2018, primarily replacing Mitchell while taking in southern parts of Bright.
Mitchell had alternated between Labor and Liberal, most recently won by Liberal MP Corey Wingard in 2014.
Bright was Labor-held from 2006 until 2014, when Liberal candidate David Speirs won.
Speirs moved to Black in 2018. He became Environment Minister in the Liberal government and served in that role until the government’s defeat in 2022. Speirs was personally re-elected, and became the Liberal party’s new leader in opposition. He stepped down as leader in August 2024 and quit parliament in October 2024.
The 2024 by-election was won by Labor’s Alex Dighton, gaining a swing of 12.6% on the two-party-preferred vote.
- Alex Dighton (Labor)
- Sarah Luscombe (Greens)
- Paula Wilson (One Nation)
Assessment
Typically this seat would be at high risk of going back to the Liberal Party, considering the circumstances of the by-election. But Labor’s strong polling puts them in a good position to retain this seat.
