Over the past two decades, Australia's koala population has almost halved - with the species now being classified as endangered.
But while the furry marsupial is one of the main drawcards for people who holiday Down Under, many don't realise just how close they are to extinction.
Today is 'Save the Koala Day' and Featherdale Wildlife Park's Chad Staples said habitat is one of the main reasons the koala population is struggling to survive.
"Unfortunately koalas are primarily found on the east coast which is where we all want to live and we haven't quite figured out how to have population growth yet still maintain habitat," Chad told Today Extra.
With the bushfires of the past couple of years on top of urban development, some might suggest just re-homing impacted koalas elsewhere.
But Chad said people don't realise this can be just as dangerous for them.
"You can't just move a koala from one section to another," he said.
