Bindi Irwin and her family are working around the clock to help the thousands of animals affected by devastating wildfires ravaging Australia.

Irwin — the daughter of famed wildlife conservationist Steve Irwin, who gained popularity through his TV series "The Crocodile Hunter" — took to Instagram to assure her followers that her family's zoo is not in harm's way.

"I wanted to let you know that we are SAFE," Irwin, 21, wrote Thursday. "There are no fires near us @AustraliaZoo or our conservation properties."

However, many displaced animals have come through the doors of the Australia Zoo Wildlife Hospital, which is owned by her mother Terri Irwin.

"Our Wildlife Hospital is busier than ever though, having officially treated over 90,000 patients," she wrote, adding, "My heart breaks for the people and wildlife who have lost so much."

She continued: "My parents dedicated our Australia Zoo Wildlife Hospital to my beautiful grandmother. We will continue to honour her by being Wildlife Warriors and saving as many lives as we can."

Irwin said she's dedicated her life to "stand(ing) up and speak(ing) for those who cannot speak for themselves," now more than ever. She shared a heartbreaking picture of an animal that recently succumbed to her injuries.

"Blossom the possum was admitted to the #AustraliaZoo Wildlife Hospital after being caught in one of the bushfires burning in other parts of Queensland," she wrote Friday. "Devastatingly this beautiful girl didn’t make it even after working so hard to save her life…This is the heart-wrenching truth."

An estimated 480 million animals have been affected by the wildfires in Australia’s New South Wales alone since September, according to ecologists from the University of Sydney.

"Many of the affected animals are likely to have been killed directly by the fires, with others succumbing later due to the depletion of food and shelter resources and predation from introduced feral cats and red foxes," the statement adds.

The early and devastating start to Australia’s summer wildfires has claimed 23 lives and already burned about 12.35 million acres of land and destroyed more than 1,500 homes. That’s more acres burned in Australia than any one year in the U.S. since Harry Truman was president.
