MP retires as Liberals leader reshuffles frontbench

Ms Andrews, who represents the Gold Coast seat of McPherson, was first elected in 2010.

She was a cabinet minister from 2018 until the fall of the Morrison government at the 2022 election.

The decision, which she will announce on the Gold Coast later on Tuesday, comes as Mr Dutton is expected to unveil a reshuffled frontbench in Adelaide.

Senior shadow frontbencher Anne Ruston is expected to take on the Indigenous Australians portfolio vacated by Julian Leeser, who resigned from his role to campaign for the 'yes' case.

Senator Ruston is a former cabinet minister, having previously overseen families, social services and women's safety.

Mr Dutton is to widely expected to promote two Indigenous Liberals, Jacinta Price and Kerrynne Liddle, to assistant ministry roles.

There is speculation Michaelia Cash will add attorney-general to her shadow portfolio.
