    Anna Heusler and a group of cyclists were riding towards Adelaide on Friday when they spotted a koala sitting in the middle of the road. It wasn’t the first time that Heusler had seen koalas out and about on the roads while riding—but this koala’s reaction amazed her. ''We stopped the bikes to help the koala get off the road, otherwise it would get hit by cars. But the koala walked up to me very quickly. It was obviously very thirsty, '' Heusler told CNN.

''As I was giving it a drink from our water bottles, it climbed up onto my bike. I've never seen a koala move so quickly. They're usually not pet animals, they stay up in the trees and people admire them from afar. ''

''None of us have ever seen anything like it. We gave it as much as we could and then made sure it was off the road and back to safety. ''Heusler shared the adorable yet heartbreak-ing images to her blog, showing the koala drinking water from her bottle. ''Australian Koala Bears suffered severe thirst in a heatwave. This koala walked right up to me as I was going down and climbed up onto my bike while I gave it water, '' she captioned the image. The video has since gone viral online, ranking top of millions of views on social media around the world. ''There's nothing but tragedy in Australia. It's burning out of control'' Heusler said. ''I hope this incident helps spread awareness. ''

Severe fires in the Adelaide Hills have burned 25,000 hectares of land，leaving koalas searching for food and water hard. Adelaide Koala Rescue's Jane Brister is currently caring for 46 koalas that have had their homes destroyed. She said the centre doesn’t normally care for this many koalas at once and the increase was due to the fires. ''A big problem we’ re noticing now is that koalas are coming in starving… there's just no food, '' Ms Brister said. Koalas eat eucalyptus (桉树)leaves—but thousands of trees have been destroyed by fires. Firefighters now across the country are taking time to care for wildlife when they find them before handing them to the correct authorities.
