Jo Clay has won the support of the ACT Greens' membership to serve as the party's next leader and vowed the party would stay focused on delivering "tangible solutions" for Canberrans.
Andrew Braddock, the Greens' member for Yerrabi, ran unopposed for the deputy leadership.
Ms Clay said she received 61 per cent of the members' vote and there had been "really, really high participation" in the ballot.
"I think a lot of people are hurting in Canberra at the moment. I think our government hasn't actually heard that very well," Ms Clay told ABC radio on Tuesday morning.
"I'm hearing a lot of anger at town halls. There's a lot of people who are finding life increasingly unaffordable. Housing is increasingly out of reach. People are worried about climate change. They're looking at European heatwaves and really worried that their government is not looking after them.
"So I think an ability to deliver firm solutions on the ground, tangible solutions to some of these daily problems and big picture problems is really important to people."
Ms Clay had earlier said in a statement she was honoured and grateful to have been elected by the party's members to the position.
"Canberrans want a government that will ensure housing is affordable, no one sleeps rough, the climate is protected, and the cost of living doesn't keep them up at night. And the Greens will keep fighting with everything we have," Ms Clay said.
Party members learned of the result at a party forum meeting held in Tuggeranong on Monday evening.
Every ACT Greens member was eligible to vote in the secret ballot to determine the next leader, the party's unique process of selecting a parliamentary leader.
Ms Clay defeated Rebecca Vassarotti for the post of leader, which went to a secret ballot of members after Shane Rattenbury resigned from the Legislative Assembly in May.
"I'd like to acknowledge Rebecca Vassarotti, whom I'm delighted to have back alongside us as our member for Kurrajong. Rebecca cares deeply about community and democratic collaboration. I look forward to working together with her to deliver progressive outcomes for Canberrans," Ms Clay said in a statement.
"My focus now is firmly on what comes next - because Canberrans deserve better than the status quo.
"As seen in the latest budget, the Greens fought to scrap the $250 health levy, reinstate the rent relief fund, take climate action, protect our precious wildlife and bushland, and secure stable funding for the community organisations that hold our city together - and we won."
Ms Clay acknowledged mixed views in her party over the possibility of the Greens forming government with the Canberra Liberals, which had been explored in extensive talks over summer.
"I don't think it's the right time to go into a coalition with the Canberra Liberals because we had that conversation. That conversation's finished," Ms Clay told ABC radio on Tuesday.
"We're not having that again at the moment and we are actually talking to our members at the moment about what should come next so we are engaged in a process to work that out and we're having that conversation over the next few months.
Chief Minister Andrew Barr congratulated Ms Clay on her election and said ACT Labor would continue to work with the Greens through the parties' supply-and-confidence agreement to deliver a "shared, progressive agenda for Canberra".
"At a time when divisive and populist politics are on the rise elsewhere, it is important that we stand together for equality, respect and inclusion, and ensure Canberra remains a welcoming place for all," Mr Barr said in a statement.
Mr Barr signed the supply-and-confidence agreement with Mr Rattenbury in November 2024 after Labor and the Greens could not find a way for the Greens to join cabinet in post-election talks.
Mr Braddock said he was proud the leadership ballot was conducted in an overwhelmingly positive and supportive way.
"I'm excited to stand alongside Jo Clay as deputy leader and feel really confident about our party's future. While the formalities are being announced today, our party room is continuing to work together on bold solutions and make sure no Canberran is left behind," Mr Braddock said.
Ms Vassarotti announced she would seek the leadership after her return to the Legislative Assembly was confirmed in a countback on June 4 that had been triggered by Mr Rattenbury's resignation.
Ms Clay, who has acted as leader since Mr Rattenbury retired, also confirmed she would seek the position permanently after Ms Vassarotti's return.
Pressed whether the ACT Greens must also accept some responsibility for the state of the ACT's budget after long serving with ACT Labor, Ms Clay told ABC radio the Greens priorities had been consistent but the party's values were easier to see outside cabinet.
"I think being one person of eight, or three of nine, and not being the treasurer or the chief minister and not having the financial reins is one thing.
"I think what people probably don't see is when we were in government, we probably still, we said the same things that we are saying now but you say it inside cabinet and then you cannot repeat it outside of cabinet."
Ms Vassarotti and Ms Clay last competed for the party's then newly established deputy leadership. Ms Vassarotti narrowly defeated Ms Clay in the 2024 vote.
Ms Vassarotti's re-election was confirmed by the ACT Electoral Commission, which ran a computerised countback to fill the seat vacated Mr Rattenbury, who resigned from the Assembly in May.
The countback process effectively means the voters who elected Mr Rattenbury determined who would replace him.
The ACT Greens also confirmed their areas of portfolio responsibility on Monday night.
