Jimmy Barnes' critically-acclaimed new memoir Working Class Man is the #1 book in Australia. 

The book, follow-up to the Aussie legend's 2016 Working Class Boy, has gone straight to top spot on the Neilsen Bookscan chart today after selling over 20,000 copies and eBooks in its first week.

The debut sees Working Class Man knock Dan Brown's Da Vinci Code from #1 in Australia, while Working Class Boy has also returned to the top ten. 

"It's not often I'm lost for words but this is about as close as I get," Barnes said.

"I spent decades trying to keep all this stuff hidden from people but it turns out that talking about it is the best thing I’ve ever done. On behalf of my liver I just wish it had occurred to me to do it a bit sooner!"

The news comes after Barnes appeared as guest host on The Project on Wednesday night, where he performed a rendition of Natalie Imbruglia's cover hit track, Torn, to celebrate the song's 20th anniversary.

Meanwhile, a feature-length documentary on the Cold Chisel frontman is set to be released next year.

Barnes will embark on a 30-date tour of the country next March in support of the new memoir; for a look at all of the dates, click on theGuide.
