Five words that prompted a candid confession from Treasurer Jim Chalmers - as he opens up about giving up drinking and doing nothing in moderation in raw and honest interview

Federal Treasurer Jim Chalmers has revealed he drank 'beers and wines' almost every night for several years and finally swore off booze for the sake of his children.

Dr Chalmers made the stunning revelation during a wide-ranging interview in which he also gave a candid response to suggestions about his behaviour in Canberra.

Discussing his decision to quit drinking, the Treasurer was asked about talk of him 'cutting a bit loose socially' around Parliament House.

'Because I was drinking too much,' Dr Chalmers told Good Weekend magazine.

He added that this wasn't behind his decision to go teetotal, rather that he wanted to focus on the 'big, serious job on the 'big, serious job' of helping lead the country.

'I knew that if I wanted to do a big, serious job, I couldn’t keep drinking six or seven nights a week, basically,' he said.

The Queenslander said he did not want to teach his children Leo, 8, Annabel, 6, and Jack, 4, that drinking was the normal way to unwind.

'For their whole life, up until three years ago, my main way of winding down was to drink beers and wines at night on the couch. And it wasn't one or two,' he told the publication.

'I didn't want them to get to a certain age and think that's what adults do every night.'

Among other topics discussed in the interview was Mr Chalmers' road to becoming Federal Treasurer, having developed a passion for politics and history in high school courtesy of one of his teachers.

He would later write to the same teacher after completing a PhD in political science and international relations to thank him for his support.

But it was Paul Keating's biography, which he stumbled upon at the age of 17 that instilled in him a deep determination to pursue a political career.

His PhD thesis was his own version of Keating's story which he titled 'Brawler statesman'.

The keen sports nut talked about his love of the Broncos and how he still plays basketball and trains at his local F45 gym whenever he can.

His newfound health kick was perhaps also spurred on by a frightening bout with skin cancer, having a melanoma cut from his chest in late 2020, which affected him for months as the wound refused to heal properly.

At one point he spent the night in a Canberra Hospital emergency room before fronting up to cameras at Parliament House the next morning on no sleep.

His fondness for the music of 90s hip hop stars like Snoop Dogg and Tupac also rated a mention but his candid comment: 'I don’t do moderation, in anything' is perhaps the most telling admission about why he has risen to the second most powerful job in the nation.

'I'm always going 100 miles an hour. If I eat a piece of chocolate, I eat a block of chocolate. If I want to work in politics, I want to be the treasurer. If I want to go for a run, I want to run 20 kilometres.'
