This field is for validation purposes and should be left unchanged. Younger females will usually birth a joey each year. Older animals may only reproduce every two or three years.

Thanks to reintroductions, Koalas are still distributed over much of their former range, but numbers have been drastically reduced and populations are becoming fragmented by the reduction in continuous habitat.
Koalas continue to be most abundant on the central and north coast of NSW and the south east corner of Queensland. Animals vary in size and colour depending on their location. Those in southern NSW and Victoria are often larger and slightly darker, with thicker fur than northern populations — probably an adaptation to keep them warmer in cooler climates. Koalas can live 13 to 18 years in the wild, and have few natural predators.
Dingoes may prey upon some on the ground and birds of prey such as owls or Wedge-tailed Eagles are threats to young. Koalas sometimes move around on the ground to swap between trees.
However, humans are directly responsible for the decline in Koala numbers since European settlement. Love for these iconic animals was initially expressed through their systematic slaughter, to meet the demand for skins in London. The Koala was protected in Victoria in , and NSW in but despite some protection in Queensland from , the slaughter of Koalas continued.
From the last quarter of the nineteenth century to the s there was a thriving trade in the skins of native animals. One million Koala skins were sold in the open season in and as many as two million were estimated to have been exported in However, they can be quite picky eaters, eating less than 50 of over eucalypt species.
However, they do drink from various water sources when needed, especially during heatwaves and in times of drought. The disease can cause blindness and reproductive tract infections. Many koala populations are faced with nowhere to go when their forest habitat is destroyed by deforestation.
Just in the last two years, tree-clearing has tripled in New South Wales, leaving important koala habitats incredibly fragmented or completely lost.
With their trees gone, koalas are spending more time on the ground in search of food and shelter. Sadly, koala numbers are on the decline. Their numbers have been falling further and further every year due to deforestation and disease. Then, Australia was ravaged by the most devastating, unprecedented bushfire season the country has ever seen. Tragically, nearly 3 billion animals, many found nowhere else in the world, perished.
Many struggling Australian species, like our koalas, have now been pushed even further towards the brink of extinction. Female marsupials have a pouch in which they carry their baby , called a joey.
Many marsupials, like kangaroos, have a pouch that opens upward, toward their head. But koalas have a pouch that opens toward their hind legs. This adaptation keeps burrowing marsupials like wombats, which are close relatives of koalas, from getting dirt in their pouch when they dig. Although prehistoric koalas eventually stopped burrowing and started living in trees, they still have the primitive, back-facing pouch.
A koala, like other marsupials, begins life in a very unusual way. When it is born, it is only about the size of a large jelly bean and is not yet fully developed. In fact, a newborn joey can't even see or hear, but it sure can climb! Soon after the joey is born, it uses strong forelimbs and hands to crawl from the birth canal into its mother's pouch.
The joey attaches to one of two nipples in this warm, safe place where it drinks milk and grows during the next six months.
Even after it starts leaving the pouch, a joey returns there when it wants to hide or sleep. Sometimes it rides on its mother's belly. After it grows too large for the pouch, the joey climbs onto its mother's back and holds on with strong hands and feet.
After about a year, it can live alone in the trees. Koala joeys learn to eat eucalypt leaves on their own gradually. At first the joey goes after leaves with its mouth.
Its early attempts look like a game of bobbing for apples, with its nose getting in the way and pushing the leaves out of reach! Fortunately, joeys keep trying until they are successful. Eventually they figure out how to grab leaves with their hands and put them in their mouth. Wildlife care specialists at the Zoo say that each koala has a unique personality. Koalas make several different vocalizations, from snores to bellows to screams.
Our conservation scientists are trying to understand why male koalas bellow. Is it to tell other males to stay away or to invite females to visit? The bellow sounds like a mixture of a motorcycle revving and a pig snorting!
The male koala has a bare patch on the chest where his scent gland is located. The male rubs that spot against a tree trunk or branch to mark it with his special smell.
We took samples from the males at different times of the year to see if the scents changed and discovered that male koalas are smelliest in spring, when they would be trying to attract a mate.
