Lidia Thorpe joined anti-voice Coalition senators to push for inquiry into Indigenous bodies

Guardian Australia understands that Thorpe was consulted on the terms of reference of the inquiry, which aims to investigate the administration of land councils and other Indigenous bodies. She signed on before gaining Greens party room approval.

Thorpe has not ruled out supporting the motion, currently slated for a vote when parliament returns on 6 February. It proposes an inquiry to report by November.

If the Greens agree to support the voice, which a Resolve Poll this week found was backed by 72% of Greens voters, some in the party question whether Thorpe can continue as First Nations spokesperson.

According to the journals of the Senate, on 29 November the chair of the finance and public administration references committee, Richard Colbeck, gave notice of a motion to set up an inquiry, co-sponsored by Thorpe, Price, McGrath and the South Australian Liberal Kerrynne Liddle.

The Albanese government has said that consulting the voice on policies, legislation and programs affecting Indigenous people will improve outcomes.

The Coalition has used a crime crisis in Alice Springs to argue that not enough is being done under the status quo, accusing the prime minister of ignoring existing Indigenous voices.
