The koala: a national treasure

The koala: a national treasure

Your guide to one of our most iconic species

There's nothing quite like wandering through the bush, gazing up and spotting a fluffy koala dozing in the trees above you. It's an experience that can only happen here in Australia.

But now that koalas are officially listed as Endangered in three states—Queensland, NSW and the ACT—sights like these are becoming rarer.

What makes koalas special?

Uniquely Australian, koalas are the only surviving species of an entire mammal family, and have been pictured in First Nations rock art for millennia. 

Here are 10 facts about these marvellous marsupials: 

  1. Toxic diet: Koalas only eat eucalyptus leaves, which are toxic to most other animals, and low in nutrients. This means they need to sleep up to 22 hours a day to save their energy!

  2. Special organ: To digest all these tough leaves, the koala has a special, two-metre-long pouch in their large intestine called a caecum. It's the largest caecum of any known mammal (in relation to body size)! 
     
  3. Don’t add water: The name koala comes from an Indigenous Dharug word meaning "no drink" or “no water”. They get almost all their hydration from eucalyptus leaves!

  4. Built to climb: Unlike most mammals, koalas have two opposable thumbs on each front paw, as well as rough paw pads. This gives them a vice-like grip when climbing.
     
  5. Handy padding: Koalas have thick, cartilage-padded bottoms so they can sit in tree forks for long hours and not get a sore bum!

  6. Unique fingerprints: They are one of the only animals (other than primates) that have unique fingerprints—and they’re nearly identical to human prints. 
     
  7. Backwards pouches: Koalas are marsupials, which means they carry their young in a pouch—and their pouches face backwards, so no dirt can get in them while climbing.

  8. Teeny tiny newborns: A newborn joey is the size of a peanut, and born blind, earless and hairless. Like a kangaroo joey, it must make its own way into its mother's pouch.
     
  9. Booming voices: A male koala’s bellow can be heard up to a kilometre away! They call like this to attract mates and mark territory—they also rub the scent gland on their chest onto trees to mark their range.

Why are koalas under threat?

The biggest problem koalas face is the destruction of their forest homes. 

Right now, koalas are losing their homes because of:

  • 🐄 Large-scale forest destruction for agriculture, particularly to graze cattle raised for beef
  • 🪵 Logging of trees, often to make low-value products such as paper and pallets
  • 🏘️ Removal of trees and forested areas for urban development, such as housing estates

What other threats do koalas face?

More and more, koalas are forced to cross roads to reach new patches of forest

It’s not just the destruction of forests that place koalas in danger. 

Fragmenting koala habitat—breaking up the forest to create separate, isolated patches—means koalas may have to cross busy roads and backyards to find new food sources and other koalas to mate with. 

This can lead to car strikes and dog attacks

Bowie, now a captive koala at Wildlife HQ, lost her left eye in a dog attack. She’s also been hit by a car.

When forest is destroyed, koalas are forced into smaller areas, which can cause stress, overcrowding and inbreeding

This can lead to koalas contracting diseases like chlamydia, which can cause blindness, severe urinary tract infections ("wet bottom") and leave them infertile—unable to have babies.
