Koalas have poor vision and rely heavily on their other senses. They have excellent hearing which helps them detect predators and other koalas. They have an acute sense of smell which also helps them detect other koalas and 
their favourite food trees

Koalas can sleep for up to 20 hours a day, due to their low energy diet, and the intense amount of energy required to break down toxic leaves.

Koalas are mostly active at night (nocturnal) and around dawn and dusk. However, they can be seen moving during the day if they are disturbed, get too hot or cold, or need to find a new tree.

Males begin mating at three to four years of age. Females begin mating, and can breed, when they are two years of age, generally giving birth once a year, for the next 10 to 15 years.
In February 2022 the status of the koala has recently been changed from vulnerable to endangered. The change in status means an increased level of protection for koalas in Queensland, New South Wales and the Australian Capital Territory.
