The koala is a tree-dwelling marsupial native to Australia, known for its specialised eucalyptus diet and pouch-raised young. It is often called a 'koala bear,' but it is not a bear.

What is a koala?

Koalas are tree-dwelling marsupials with thick grey fur, large ears, and strong climbing claws. They spend most of their time resting in eucalyptus forests and rely almost entirely on eucalyptus leaves for food.

Where do koalas live?

Koalas are native to eastern and south-eastern Australia, including parts of Queensland, New South Wales, Victoria, and South Australia. They inhabit eucalypt forests, woodlands, and some coastal or island habitats.

Are koalas endangered?

Conservation status varies by region and authority. Some Australian koala populations are listed as endangered, while broader global assessments list the species as vulnerable overall.

In short

  • Koalas are marsupials, not bears.
  • Their diet is almost entirely eucalyptus leaves.
  • They sleep up to 20–22 hours a day.
  • Some Australian populations are endangered.
Canadian angle

Koalas are of interest to Canadian readers mainly through wildlife education, zoo and conservation coverage, and school reference material about marsupials and Australian ecosystems.
