The 2025 Australian Senate election was held on Saturday, 3 May 2025 to elect 40 of the 76 senators in the Australian Senate as part of the 2025 federal election.[1] Senators elected at this election will take office on 1 July 2025, with the exception of the senators elected from two territories whose terms commenced from election day.[2] The elected senators will sit alongside continuing senators elected in 2022 as part of the 48th Parliament of Australia.[3]
Labor was set to hold 28 seats in the new Senate, making this the first time Labor was the largest party in the Senate since the 1984 election. On 2 June 2025, Greens Senator Dorinda Cox left the Greens and joined Labor, taking the number of Labor Senators to 29 in the new parliament beginning on 1 July 2025.[4]
^The UAP was voluntarily de-registered in 2022 and, therefore, cannot appear on the ballot paper. Incumbent senator and party leader Ralph Babet is not up for election and is permitted to sit as a member of the UAP despite the party's de-registration.
