The Irwins Treat Hundreds of Displaced Animals as over 1B Creatures Are Feared Dead from Australia's Wildfires

The Irwins have been doing their bit to treat as many displaced animals as possible in the Australian fires that has left over a billion creatures dead in its wake.

Speaking to PEOPLE, the Irwins recounted some of the most emotional moments they have witnessed in the disastrous wildfires that rocked Australia.

Terri Irwin, 55, revealed that for her, the most emotional moment was watching the people on the front line. She also appreciated the firefighters for their contributions despite the numerous challenges that came their way.

She also said that there were firefighters from all over the world, including the US and Canada, and that as the animals ran out of the forests in search of help, they walked straight to the firefighters, who give them water.

The firefighters would then end up having to carry the animals, who usually climbed up on them in search of refuge. Continuing, Terri said:

"It's just heartbreaking watching these heroic firefighters also trying to save wildlife. It's unbelievable…when these animals are terribly injured, they're hit by cars, they're burned, they're trying to seek solace wherever they can — it really is heartbreaking to watch."

16-year-old Robert Irwin shared similar sentiments with his mother, saying that he witnessed the devastation from all across Australia. He added that it was heartbreaking to see the dangers that all the animals faced.

The Irwin Family are treating hundreds of animals displaced as a result of the fire at their wildlife hospital at the Australian zoo. At the last count, they had treated 90,000 animals.

"The first time I met @robertdowneyjr was when I was just a few months old when he and his family visited @australiazoo – it was awesome getting to catch up again to chat all things #Dolittle ! One of the kindest people you'll meet, and an incredible advocate for the environment!"

The meeting between Robert and Robert Downey Jr. was as a part of an interview segment on the "Today Show." Accompanying Robert's post were two photos; the first, showed their recent meeting, and the second, a picture of the very first time they met.

Despite the efforts being made by the Irwins, Robert's older sister, Bindi Irwin, wishes that her late father, Steve was alive, because he would have given her strength and advice on what to do during the devastating fires.

Bindi made the admission in an Instagram post, where she shared a photo of her dad holding an animal. Bindi added that she hopes she could make her dad proud and that his spirit lives through their work.
