International pop superstar P!nk has made an incredible pledge toward Australia's frontline firefighters as the nation's bushfire crisis continues.

Taking to Twitter, the US artist expressed her distress at the country's current emergency.

"I am totally devastated watching what is happening in Australia right now with the horrific bushfires," she said.

"I am pledging a donation of $500,000 directly to the local fire services that are battling so hard on the frontlines.

"My heart goes out to our friends and family in Oz."

People around the world have jumped at the chance to be able to help out those battling the catastrophic blazes Australia has faced this bushfire season.

Australian comedian Celeste Barber's fundraiser has raised more than $4 million for The Trustee for NSW Rural Fire Service and Brigades Donations Fund, prompting a worldwide fan base to contribute.

"Donated from Somerset, England. Shared via Facebook and Instagram and some of my friends have shared too. It is great to see the snowball effect working," Lizzie Tucker wrote.
