Perry was greeted by dozens of firefighters at her concert on Wednesday, saying her show was a chance to raise the spirits of those in the region.

"I just think it reminded me of home and that's why it struck a chord in my heart," she said of the fires.

Despite being thousands of kilometres away in California as bushfires burned in Australia over summer, Perry says the fires had hit close to home.

The 35-year-old, a native of Santa Barbara outside of Los Angeles, said watching the stories that came out of the North East made her want to help.

"I'm from a local little town that's like this, that went through a similar situation like this one," she said from Bright on Tuesday afternoon.

"And so I felt really close to it."
