The Oscar-nominated actress, who grew up in the Gold Coast Hinterland in Queensland, became emotional during the Instagram video while looking through her childhood photos on her family farm in Australia.
"I'm sure you're all aware of what's happening in Australia at the moment with the fires. I didn't want to show you more pictures of the devastation," she said on the video.
The Bombshell star then began to tear up as she put out a plea for help.
