Australia's devastating bushfire crisis has been ongoing since September, with fires blazing in every state in the country. And tragically, at least 25 people and 500,000 animals have died as a result of the fires. In addition, over 2,000 homes have been destroyed.

Given the severity of the fires, many people, including a number of Australian stars, have pledged to do what they can to tackle the crisis.

Chris Hemsworth and his family, for instance, have donated $1 million to bushfire relief, he revealed in a post to Instagram.

Many ordinary Australian citizens have also been doing what they can to help.

This heartwrenching footage shows a kind-hearted grandma rescuing a severely injured koala who was unable to escape the raging fires:

Two teenage boys, in fact, have taken it upon themselves to travel around the worst-hit areas of the country allowing koalas into their car in order to protect them from the fires.

Micah, 19 and his Caleb, 18 posted a short clip on YouTube, filmed on Kangaroo Island, showing the inside of a car with several koalas perching on various parts of the car.

The pair believe they have rescued around 20 koalas.

"Rescuing Koalas affected by fires on Kangaroo Island with my cousin," they shared in the description of the YouTube post. "Little fellas looking a little exhausted. Shoved the mother in the boot because she was a bit aggressive."

The video was also shared on Reddit with the caption: "Amid the terrible bushfires in Australia, my cousins went out and saved as many koalas as they could. Good on 'em."

The teens plan to take care of the animals until it is safe to return them to the wild.
