5 Seconds of Summer's Ashton Irwin Goes Shirtless For Australia Fire Fight Concert

5 Seconds of Summer hit the stage at the Fire Fight Australia Bushfire Relief Concert held at ANZ Stadium on Sunday (February 16) in Sydney, Aus.

The guys – Michael Clifford, Luke Hemmings, Calum Hood, and Ashton Irwin – joined many other artists to perform at the event to help raise money for Australian fire relief efforts.

“Thank you for having us at The Australian Fire Fight concert! It will go down as one of my favorite memories of @5sos’s career 🖤,” Ashton wrote on Instagram with a shirtless pic from the concert.

Michael recently opened up about why he hasn’t been so active on Instagram. Find out why he’s barely been on the social media platform lately!
