This koala was found clinging to the axle of a four-wheel drive in Australia. It's thought the female crawled under the vehicle's wheel arch while it was parked in the hills near Adelaide. The driver only discovered the hitchhiker after making a 16km (10-mile) journey. Rescuers had to remove the wheel to free the koala. It has now recovered from its ordeal and has been released back into the wild. koala hitchhiker adelaide australia animals lucky
