Former Queensland Senator Mark Furner will replace fallen Transport Minister Stirling Hinchliffe in the the Palaszczuk government's cabinet.

The Member for Ferny Grove won a reportedly close vote over Logan MP Linus Power on Wednesday night.

A spokesman for the Premier confirmed Mr Furner's elevation but said he was not likely to be endorsed by caucus until Friday.

Mr Furner, a member of Labor Forum after previously being part of the Old Guard, was being mentioned as a possible replacement earlier this week in the wake of Mr Hinchliffe's resignation.
