SA-Best (stylised SA-BEST), formerly known as Nick Xenophon's SA-BEST, is a political party in South Australia. It was founded in 2017 by Nick Xenophon as a state-based partner to his Nick Xenophon Team party (renamed to Centre Alliance in early 2018). After an unsuccessful 2022 South Australian state election, the party has two representatives in the South Australian Legislative Council, Connie Bonaros and Frank Pangallo, whose current terms expire in 2026. History Formation The party was registered on 4 July 2017. John Darley was the sole Nick Xenophon Team member in the South Australian Parliament until he left the party to become an independent on 17 August 2017. On 6 October 2017, Xenophon announced that he would be leaving the Federal Senate to contest the state seat of Hartley at the 2018 state election. Xenophon resigned from the Senate on 31 October 2017. At its 2018 annual general meeting, the South Australian party officially changed its name from Nick Xenophon's SA-Best to SA-Best. In late 2017, NSW-BEST, VIC-BEST, WA-BEST, QLD-BEST and NT-BEST were registered as business names, leading to speculation that the party would expand interstate. However, as of 2022, none of these have formed political parties. 2018 South Australian election In the March 2018 South Australian election, SA-Best contested thirty-six seats in the South Australian House of Assembly and put forward four candidates for the upper house. The party charged candidates $1,000 to be considered for pre-selection, and a further $20,000 for running in the lower house, or a further $40,000 in the upper house, as well as fund their own local campaign. The thirty-six House of Assembly seats contested were: Badcoe, Chaffey, Cheltenham, Colton, Croydon, Davenport, Dunstan, Elder, Elizabeth, Enfield, Finniss, Gibson, Giles, Hammond, Hartley, Heysen, Hurtle Vale, Kavel, King, Lee, Mackillop, Mawson, Morialta, Morphett, Mount Gambier, Narungga, Newland, Playford, Port Adelaide, Ramsay, Reynell, Schubert, Taylor, Unley, Waite, and Wright. The party failed to secure any lower house seats, although there was a close contest in the historically safe Liberal seat of Heysen. Xenophon unsuccessfully contested Hartley and although he came second on the primary vote ahead of Labor's Grace Portolesi by 202 votes, the preference distribution of the eliminated fourth-placed Greens candidate turned Xenophon's 99-vote lead over Portolesi into a 357-vote deficit. Third-placed Xenophon was therefore eliminated, with Hartley reverting to the traditional Liberal vs Labor contest. The party came second on primary votes in ten seats;
