In this photo provided by Queensland Police Service and taken on Nov. 6, 2016, a koala looks out from a handbag at a police station in Brisbane, Australia. Australian police made an unusual find while searching the bag of a woman who was being arrested: a baby koala. Police in Brisbane said that when they asked the 50-year-old woman if she had anything to declare, she handed over a zipped canvas bag that she said contained a baby koala. The woman, who was arrested on "outstanding matters," said she found the male koala and had been caring for it.

Thousands of koalas were feared to have died in a wildfire-ravaged area north of Sydney, further diminishing Australia's iconic marsupial.

Koalas were declared officially endangered Friday in eastern Australia as they fall prey to disease, lost habitat and other threats.
"It's killing koalas because they become so sick they can't climb trees to get food, or escape predators, and females can become infertile," said Samuel Phillips, a microbiologist at the University of the Sunshine Coast who helped to develop the vaccine.
