Queen and Adam Lambert, k.d. lang, Alice Cooper, John Farnham and Olivia Newton-John have signed to perform at a benefit concert in Sydney to raise funds for the bushfire relief effort.

The Fire Fight Australia event at the ANZ Stadium in Olympic Park will be hosted by comedian Celeste Barber, whose online bushfire fundraiser has garnered more than $50 million in donations.

Legendary British rock band Queen + Adam Lambert were confirmed for the charity event on February 16 after the band said negotiations were underway last week.

Rocker Alice Cooper, who is also touring Australia next month, has jumped on board, as well as Canadian singer-songwriter k.d lang.

The concert, which is expected to run more than nine hours, also includes local artists Amy Shark, Baker Boy, Conrad Sewell, Daryl Braithwaite, Delta Goodrem, Grinspoon and Guy Sebastian

Hilltop Hoods, Icehouse, Illy, Jessica Mauboy, Lee Kernaghan, Pete Murray, Peking Duk, Tina Arena and William Barton are also set to play.

“I’m so pumped … I’ve already started stretching,” Barber said on Facebook.

Concert promoter, TEG Dainty, said there would be many more acts announced soon and they were “inundated” with offers from artists.

Tickets for the event, which starts at 1pm, went on sale from midday on Monday through Ticketek at $100, $85 and $70 with an option to make further contributions to bushfire relief.

All profits from the sales will go toward rural and regional fire services, the Red Cross and the RSPCA.
