Labor–Greens coalition

The Labor–Greens coalition is an alliance between the Labor Party and the Greens in the Australian Capital Territory Legislative Assembly.

Unlike what generally happens with the Liberal–National Coalition, Labor and the Greens contest ACT elections on separate tickets. As of 2024, three Greens MLAs are members of the Barr ministry, while the other three effectively sit on the backbench.

History
Following the 2001 election, Labor was supported by the Greens and Democrats in a minority government. Labor won a majority in 2004, but after losing it in 2008 they were again supported by the Greens.

At the 2012 election, Shane Rattenbury was the only Greens MLA to retain his seat in the Legislative Assembly, and entered into a power sharing arrangement to allow the Labor Party to once again form minority government. The Labor Caucus agreed to appoint Rattenbury as a minister in Katy Gallagher's five-member cabinet, and to support various Greens policies.

Rattenbury was re-elected at the 2016 election and joined by party colleague Caroline Le Couteur, taking the Greens tally to 2 out of 25 total seats. As a result, Rattenbury joined the second Barr ministry, although he reserved the right to withdraw from Cabinet discussions on divisive issues and vote independently in the Assembly.

Labor was re-elected with 10 seats of their own in 2020, while the Greens won a record 6 seats. On the night of the election, Andrew Barr confirmed Labor would again seek to enter into an arrangement with the Greens. Since November 2020, Rattenbury, Rebecca Vassarotti and Emma Davidson have served as Greens ministers, making up a third of the Barr ministry.
