Zookeepers say it is very unusual to see a koala with fur this light and with eyes and skin remaining the usual brown black.
But said the koala's white coat is not caused by a condition called albinism, which is when a human or animal doesn't have the chemical in its hair, skin and eyes that creates colour.
Australia Zoo have now asked the public to help name the rare koala.
Suggestions so far include Snowflake, Diamond, Pearl and Djendaladi, meaning "white-haired" in the Noongar language.
A rare white koala joey has been born at a zoo in Queensland, Australia.
