The beefed-up Greens crossbench has vowed to stand up for the community and hold the ACT government to account, even if it means challenging party colleagues in Andrew Barr's cabinet.
Greens leader Shane Rattenbury on Wednesday announced the portfolio responsibilities for newly elected parliamentarians Jo Clay, Andrew Braddock and Johnathan Davis, who will represent the party from the Legislative Assembly's crossbench.
The retired Caroline Le Couteur was the Greens' sole crossbencher in the previous term.
The announcement came after the trio's Greens colleagues Emma Davidson and Rebecca Vassarotti were included alongside Mr Rattenbury in Chief Minister Andrew Barr's new cabinet.
With their presence in cabinet tripled, the Greens hold greater influence inside the ACT government, and therefore greater responsibility for its actions.
Ms Clay, Mr Braddock and Mr Davis, who were all elected for the first time on October 17, on Wednesday signalled that they won't hesitate in calling out the government if it means standing up for the interests of their communities.
"Nobody who has ever met me would expect me to sit quietly on any occasion," said Mr Davis, who will be the Greens' spokesman for health and education.
"The people of Tuggeranong elected me to bring their voices to the Legislative Assembly. I expect to be a very active and enthusiastic member of the party room and crossbench."
Ms Clay, who will be the Greens' transport spokeswoman, gave a blunt response when asked what type of crossbencher should would be.
"Up until recently I was a climate activist. I'm proud to say my daughter's first word was 'No' - so that might give some indication," she said.
Ms Clay was more conciliatory as she talked up the Greens' tradition of working in a team, saying she was confident of being able to "ride the fine line of working collaboratively in the Assembly, while also speaking up for the climate".
Mr Rattenbury acknowledged there would be times when the crossbenchers would need to speak up against the ACT government. He expected the "energetic" and "passionate" trio to raise issues which cropped up in their local communities in the Legislative Assembly chamber.
But he said the six members of his team, regardless of whether they sat in cabinet or on the crossbench, were committed to working together to achieve positive outcomes.
Under the terms of the power-sharing agreement struck with Labor, the Greens are required to support policies once they have been endorsed by cabinet.
However the party does retain the ability to vote against Labor bills or motions, a feature of the agreement which Mr Rattenbury said allowed the two parties to have disagreements without "collapsing the government".
"We [Greens members] have all signed up the parliamentary agreement, and that outlines very clearly our intent to have a collaborative, co-operative government that is focused on getting things done," he said.
"That is the role that I anticipate all the members of the Greens will play, whether they are ministers or not ministers.
"We want to be successful this term, we want to get jobs done. But there will be times when questions need to be asked, and I think that our team can do that in a way that's about getting outcomes."
New Liberal leader Elizabeth Lee is expected to unveil her shadow cabinet in the coming days.
