Labor and the Greens are poised to unveil their power-sharing agreement for the next four years of government, following high-level talks between the two parties.
Chief Minister Andrew Barr and Greens leader Shane Rattenbury are aiming to finalise the new parliamentary agreement on Monday, ahead of a ceremonial sitting of the new ACT Legislative Assembly the following day.
Mr Barr will be reconfirmed as chief minister during Tuesday's formalities, which will also see the eight newly-elected members sworn in and a new speaker elected.
Mr Barr and Mr Rattenbury, along with senior staff, have been locked in private talks throughout the week on the parliamentary agreement, thrashing out a list of shared priorities for the two parties and the terms under which the Greens will guarantee Labor's hold on power.
"We have been steadily working our way through it this week," Mr Rattenbury told ABC radio on Friday morning.
"It is a bit of a detailed process, we are talking about setting up a four-year plan, a four-year agreement because we want to have a stable government right through the term.
"Both parties took detailed agendas to the election, and so it's also about working through those two agendas, finding any places of difference and negotiating through those."
The parliamentary agreement struck after the 2016 election included 89 items, including a commitment to build the Gungahlin light rail line, establish an integrity commission and reach the 100 per cent renewable energy target.
The government failed to deliver on about one in five of those items, including an expansion of the lobbyists register.
The timeline for phasing out natural gas as well as gaming machine laws loomed as potential points of conflict in this round of negotiations, after Labor and the Greens clashed over the issues during the term and election campaign.
The Greens entered these talks in a far stronger bargaining position than four years ago, having expanded their representation in the Legislative Assembly from two to six members after their historic ACT election result.
Mr Rattenbury on Friday reaffirmed his view that the Greens should be entitled to three positions in Mr Barr's cabinet, up from one in the previous term.
Mr Barr has warmed to the idea of having two Greens in cabinet, after previously declaring it was highly unlikely that any new parliamentarians would be handed ministerial portfolios immediately.
The chief minister has the option of expanding his cabinet from eight to nine members to accommodate an extra Green minister or promote a Labor backbencher.
Mr Barr has foreshadowed a reshuffle of his cabinet, which will need to factor in the appointment of a new Attorney-General after Gordon Ramsay lost his seat in Ginninderra.
The Labor leader had indicated Mr Rattenbury would be in running for the senior position if Mr Ramsay failed to reclaim his seat.
