The Big Five-O Live

The Big Five-O was a concert tour by Australia rock group Cold Chisel. The tour celebrated the group's fiftieth anniversary. The 11-date tour was announced in May 2024. Three additional dates were added on 31 May and three more on 3 June 2024. On 12 June, Cold Chisel confirmed all 16 of the 17 dates were sold out and added six more shows, bringing the total to 23 for Australia.

Band member Jimmy Barnes said "The Big Five-0 is a landmark moment, there have been plenty of times where I never thought I'd live to see this day so I'm going to make the most of it. I can't wait to celebrate with my mates and with all the fans who have been such a big part of our story. We're gonna smash it." Don Walker added "This 50th anniversary tour will be a huge celebration – for all of us."

The band performed a secret show as Barking Spiders on 3 October 2024. A total of 24 dates across Australia were completed.

The 23 November 2024 Sidney Myer Music Bowl performance was recorded. Barnes said "Every show on our Big Five-0 Tour had something special, but the Sidney Myer Music Bowl in Melbourne, with 37° temperatures and an incredible audience, really brought out a blistering and joyous performance from all of us onstage. The crowd nearly drowned us out, they sang so loud and proud. It was a show we will never forget."

The performance screened on 7 Network on 11 May 2025. It was the ranked fifth on the night and was viewed by 1,845,000 people.

On 2 July 2025, Cold Chisel confirmed the Sidney Myer Music Bowl performance will be released commercially on 8 August 2025.
