Former premier Jeff Kennett says if he were former Liberal leader Ted Baillieu, he would quit politics.
Mr Baillieu, who was elected premier in 2010, quit the top job in March, believing he had lost his colleagues' support and was replaced by Denis Napthine.
He now sits on the government's backbench.
Mr Kennett says Mr Baillieu's decision on whether to stay on is a matter for him, but he's young enough to try something different and could use his profile to do good community work.
"The reality is he has been leader, he's climbed the peak, he's got to the top of the mountain. It's never going to get better than that for him," he told Fairfax Radio.
"If I was he, I'd get out and get on with the next phase of my life.
"Otherwise you're caught in this timeframe where you're looking back to what you were and what you might've been."
Mr Kennett's comments came as it emerged Liberal Community Services Minister Mary Wooldridge may be looking for a new seat after she lost hers under a redistribution released on Thursday.
