We rate them: four Labor backbenchers vying to be the ACT's sixth minister

Yvette Berry - Most likely

The first-term MLA is considered the favourite to enter cabinet.

Ms Berry has been a quiet achiever during her first 12 months as a politician. She's championed issues close to her heart, including the plight of low-paid workers and the need for improved services in west Belconnen.

Like Chris Bourke, Ms Berry is an MLA for the electorate of Ginninderra, which is currently unrepresented in cabinet.

Ms Berry could soon follow in the footsteps of her father Wayne by serving in a Labor cabinet.

Mick Gentleman - In with a chance

The government whip, who once worked as a security guard in the prime minister's office, is politically ambitious.

He loyally champions the government's agenda from the backbench.

Mr Gentleman was first elected as an MLA for Brindabella in 2004 but lost his seat at the 2008 election.

His political career was resurrected at the 2012 poll, following the retirement of Labor stalwart John Hargreaves.

Mr Gentleman doesn't have the same political flair as Mr Hargreaves - but that's not always a bad thing.

Mary Porter – Outside chance

The hard-working Ginninderra MLA missed out to Liberal Vicki Dunne on winning the speaker's chair last year.

Outspoken on a range of issues, Ms Porter has been a champion of older Canberrans and recently taken up the issues of end-of-life care and euthanasia.

As one of the older MLAs, she may miss out on a cabinet spot in order to facilitate generational renewal.

Chris Bourke – Outside chance

As a rookie MLA, Dr Bourke served as a minister for almost a year at the end of the last Assembly.

The former dentist won a seat in the Assembly by countback after former chief minister Jon Stanhope retired.

A lack of time and experience made it hard for Dr Bourke to find his feet as education and corrections minister.

But he's made no secret of his desire to have another stint on the ACT Executive.
