Federal Labor MP Joel Fitzgibbon has announced he will not contest the next election, calling time on his outspoken political career.
Mr Fitzgibbon on Monday confirmed he would not re-contest the regional NSW seat of Hunter, which he's held for a quarter of a century.
He quit the shadow frontbench last November, warning the party risked alienating voters in regional seats like his own by committing to overly-ambitious action on climate change.
Mr Fitzgibbon has backed Anthony Albanese to win the next federal election, declaring he leaves politics confident in the party's direction.
"These decisions are never easy but I do it quite comfortably," Mr Fitzgibbon told the ABC.
He insisted he worked closely with Mr Albanese over the past two-and-a-half years, despite public tensions on climate policy.
"I've urged him back to the centre ground. I've urged him to focus on the things that are really important to working people," Mr Fitzgibbon said.
He said the opposition leader had expressed support for coal mining - a key industry in Hunter - and the gas sector while also pledging meaningful climate action.
"I believe he has struck a very good balance and I think as a result he's well placed to lead us to an election victory.
"If we are going to meet our aspirations on climate change we need to take the community with us and put to an end these endless climate war and debates."
The right faction heavyweight and Labor's most senior regional MP was increasingly outspoken after suffering a major swing against him at the 2019 federal election.
Labor holds Hunter with a three per cent margin.
Before Mr Fitzgibbon held the seat, his father Eric was the MP between 1984 and 1996.
"Hunter is safe and we will be competitive at the next election," he said.
He listed Olympic shooter and former coal miner Daniel Repacholi, barrister Stephen Ryan, nurse and union official Emily Suvaal, and state by-election candidate Jeff Drayton as potential replacements.
Asked whether the seat was winnable for the Nationals, Deputy Prime Minister Barnaby Joyce said: "Nothing's a walk in the park, but yes".
Mr Fitzgibbon held the agriculture and resources shadow portfolios in the Albanese opposition until quitting in November last year after a bust-up with the Labor leader.
He previously warned Labor could split into two parties because of a failure to balance the interests of inner-city progressives and working-class voters.
The 59-year-old served as defence minister under Kevin Rudd from 2007 to 2009.
He resigned from cabinet after it emerged his office helped his brother Mark, the chief executive of a private health insurance fund, in efforts to lobby Defence over contracting.
Mr Fitzgibbon returned to the ministry when Mr Rudd regained the top job in 2013.
