ABC election analyst Antony Green has analysis of the upper house result. Final primary votes gave Labor 4.41 quotas, One Nation 2.93, the Liberals 2.13, the Greens 1.22, Legalise Cannabis 0.28 and Family First 0.26.
The electronic distribution of preferences was finally conducted last Monday. As expected, Labor won five of the 11 seats (up one since 2018, the last time these seats were up), One Nation three (up three), the Liberals two (down two) and the Greens one (steady). SA-Best lost its two seats.
In the distribution of preferences, One Nation's third candidate made a full quota, while Labor's fifth was elected with 0.57 quotas. The Greens' second surpassed both Legalise Cannabis and Family First, to be runner-up with 0.46 quotas.
Preferences beyond a "1" for an above the line group are entirely optional in the SA upper house. With the final seat decided between Labor and the Greens, right-wing voters were likely to exhaust their preferences.
In 2022, Labor won five seats, the Liberals four, the Greens one and One Nation one. One Nation's winner at that election, Sarah Game, has defected. The upper house total is ten Labor out of 22, six Liberals, three One Nation, two Greens and Game. Labor and the Greens combined have 12 seats, a majority.
