Answer:
Yes, but because koalas sleep for most of the day and are chiefly nocturnal, you can usually only see them at night. They even have an albino koala, Onya-Birri (meang "ghost boy" in the language of the Aborigines") who is currently the world's only captive albino koala (but not the world's first; The San Diego Zoo used to have an albino koala named Goolara, who died of cancer; Goolara's grandfather, Kalba, was also an albino).
