A byelection occurred on Saturday in the South Australian Liberal-held state seat of Black. With all election day votes counted, Labor gained Black by a 60.6–39.4 margin over the Liberals, a 13.3% swing to Labor since the 2022 state election. Primary votes were 46.5% Labor (up 8.4%), 32.3% Liberals (down 17.8%), 15.6% Greens (up 3.8%) and 5.6% Australian Families (new).
SA doesn’t allow pre-poll and postal votes to be counted on election night, so the count is only up to 42% of enrolled voters. ABC election analyst Antony Green expects the large number of pre-poll and postal votes to reduce Labor’s lead, but Labor will still win easily. These votes will be counted from Monday.
