How we counted
- Results are the Electoral Commission of South Australia's final counts after preferences for 2022 and 2026, used as facts: who won, their party and their share in the final count.
- The 2026 election used boundaries redrawn in 2024, and Ngadjuri was a new district. A district is compared with 2022 by its name, so the ground it covers is not exactly the same.
- Every South Australian suburb page now shows its state district, its member and these results.
