SA Best

SA Best (stylised SA-BEST) is a political party in South Australia. Founded in March 2017 by Australian senator Nick Xenophon as Nick Xenophon's SA-BEST, the party hoped to gain the balance of power at the 2018 South Australian state election.

Positive initial polling figures led the party to stand candidates in 36 of 47 seats in South Australia's House of Assembly. A key policy of SA Best was to reduce the number of poker machines in South Australia, which resulted in the Australian Hotels Association campaigning against the party. At the state election, SA Best underperformed expectations, winning no seats in the House of Assembly, and only electing two members to the Legislative Council, Connie Bonaros and Frank Pangallo.

In late 2018, Xenophon resigned as a party member of SA Best, and the party removed the reference to him from their official name. At the 2022 state election, the party focused on the Legislative Council, but lost most of its support from 2018. Pangallo left the party in 2023, leaving Bonaros as the only SA Best MP remaining. Bonaros lost her seat at the 2026 state election, leaving SA Best with no representation in the South Australian parliament.
