# 1925 Australian Senate election

The 1925 Australian Senate election was held on 14 November 1925 to elect 22 of the 36 senators in the Australian Senate as part of the 1925 federal election. Each state elected three senators to serve a six-year term beginning on 1 July 1926. Due to casual vacancies, Victoria and Tasmania elected an extra senator, while New South Wales elected two extra senators.
The election was the first to implement compulsory voting following the passing of the 1924 amendment to the Commonwealth Electoral Act. The introduction of compulsory voting raised turnout to over 91%, compared with a turnout of under 60% at the previous election.
