Hemsworths pledge $1 million as more Aussie celebs urge people to help combat Australian wildfires

The Hemsworth family are just the latest celebrities to step up and take action in response to the devastating wildfires in Australia, which have resulted in the loss of at least 25 human lives and half a million animal lives, as well as the destruction of an estimated 12 million acres of land.

Chris Hemsworth took to Instagram on Monday to reveal that his family, which includes fellow actors Liam and Luke, would be donating a million dollars to help fight the horrifying fires.

"My family and I are contributing a million dollars. Hopefully you guys can chip in too," he captioned a video of himself. "Every penny counts so whatever you can muster up is greatly appreciated. In my bio I’ve added links to support the fire fighters, organisations and charities who are working flat out to provide support and relief during this devastating and challenging time. Beyond appreciative to everyone around the world for their well wishes and donations. It really does make a difference, so dig deep!"

Fellow Aussie stars Nicole Kidman and Keith Urban, as well as Kylie Minogue, have all pledged $500,000 to help combat the crisis, too.

"Our family’s support, thoughts and prayers are with everyone affected by the fires all over Australia," announced on Instagram. "We are donating $500,000 to the Rural Fire Services who are all doing and giving so much right now."

"Last year I had the incredible opportunity of visiting some of the many beautiful places in my homeland for the first time. Returning home to such devastation throughout much of the country is heartbreaking," Minogue said. "As a family, we’ve donated $500,000 towards the immediate firefighting efforts and the ongoing support which will be required. Big or small, from near or far, any support will help those affected by the devastating bushfires."

Australian actor Russell Crowe has also taken action, skipping Sunday's Golden Globe Awards to stay in Australia to help on the ground "protecting his family." When he won an award during the ceremony, presenter Jennifer Aniston read a pre-written statement on Crowe's behalf.

"Make no mistake, the tragedy unfolding in Australia is climate change-based," he said. "We need to act based on science, move our global workforce to renewable energy and respect our planet for the unique and amazing place it is -- that way we all have a future. Thank you."

Another celebrated Australian star, Hugh Jackman, took to Instagram to call attention to several organizations that people can donate to as the fires continue to rage on, tagging them on a photo of a volunteer and a little girl wearing protective masks.

"How can you help? Tap on the image for just a few of the organizations who are working tirelessly to fight the bushfires ... to save lives, wildlife and property," he captioned the post.

Oscar-nominated actress Margot Robbie also used her platform to spread awareness of the fires and how people can help, posting a video to her IGTV on Instagram in which she shared some of her fondest memories from growing up in Australia.

"I didn't want to show you more pictures of the devastation. I wanted you to see how beautiful our country is, because it is so beautiful, and it is really, really hurting right now and it really, really needs you. Please donate anything you can," she said. "I went on so many different websites to donate. They took me less than a minute to donate each."
