Koala is an iconic symbol of Australia.
Now a rare and endangered species of marsupial, the Koala spend their days in the treetops of the eucalyptus tree, eating and sleeping; and up until recently, rarely descending the safety of their arboreal homes to find drinking water.

The name Koala is suppose to mean ‘No Drink’, and comes from the Darug people, from the coastal area of Sydney. The once abundant marsupial, with rounded fluffy ears, grey, brown and cream downy fur, little brown eyes, black leathery nose and two opposable thumbs for each hand, was first written about by white settlers in the early part of the 19th Century. The first record was in 1798 and the first published image of a Koala was in 1810.

Koalas are one of our national emblems, and they are fast becoming extinct and we don’t seem to be doing enough to stop it.

‘No Drink’

It seems as though the Koala was doomed from the time white colonists settled the Australian shore. Plagued by habitat destruction, disease, predation from introduced species, mass slaughter and now global warming – which has resulted in extenuating drought. The Koala is now on the way to becoming extinct in the wild, the forecast is bleak.

Koalas limited food supply has altered due to drought and the quantity and  quality of their food source diminished. The Eucalyptus leaves no longer provide the adequate nutrients or hydration aKoala needs to survive. Koala, now against their namesake of “no drink”, must descend from the trees to look for groundwater, putting them at risk of predation from dogs or being hit by cars. 

Most recently Koala habitat and numbers came close to total extinction in the 2019 – 2020 bushfires in some areas of NSW entire population of Koala are now gone, burnt to death in the fires that ravaged 18 million hectares of bushland, destroying homes, wilderness and eliminating at least 1 billion animals and insects.

 This catastrophic disaster has highlighted the danger of global warming to the entire planet, not just Koalas. Scientists say we are in the beginning of the sixth mass extinction on earth, which means that plants, animals, fungi, corals and microbial life is dying off at a rate 1000 times faster than what is normal, and the main culprit is us.

We are losing our natural heritage

As it turns out Australia has the worst rate of mammalian extinction of any other country in the world and our deforestation habits are worse than the Amazon. Every year we clear around 500,000 hectares of bushland – that’s about equivalent to an area the size of the MCG every two minutes.

Our Aussie icons are losing their homes & their lives.

URGENT APPEAL: Across the country, over 15 million Australian land areas have been burned to the ground. Over 3 billion animals have been displaced because of these fires, and over 1.25 billion animals have lost their lives. Your support towards WWF-Australia’s Wildlife and Nature Recovery Fund is urgently needed to care for injured wildlife and restore their homes.  


WWF is one of Australia’s most trusted conservation organisations. At WWF, we work in Australia and our Asia-Pacific backyard to protect endangered species and habitats, meet the challenge of climate change, and build a world where people live in harmony with nature. This would not be possible without financial support from our community. Thank you! If you would like to help us,
