Larissa Waters

Larissa Joy Waters (born 8 February 1977) is an Australian politician and lawyer who is currently serving as the leader of the Australian Greens since May 2025. She has also served as a Senator for Queensland from 2011 to 2017, and again since 2018. Waters was first elected as a Senator for Queensland in 2010 and taking up her seat in 2011, she was forced to vacate the Senate in July 2017 in the parliamentary eligibility crisis, due to her holding Canadian citizenship in violation of Section 44 of the Constitution of Australia. Having renounced her Canadian citizenship, Waters was re-appointed to the Senate in 2018 by the Queensland Government to fill the casual vacancy created by the resignation of Senator Andrew Bartlett. She served as Greens co-deputy leader from May 2015 to July 2017 and again from December 2018 to June 2022, and as her party's Senate leader from February 2020. In May 2025, Waters was elected leader of the Australian Greens, following loss of the seat of Melbourne by then leader Adam Bandt in the 2025 Australian federal election.
