When were Koalas put on the endangered species list?

Koalas have never been on the endangered species list. During the late 1800s, koalas became an export commodity for their fur, mostly for export to the USA. Due to koala numbers dwindling and public outrage, laws were enacted protecting the koala and imports were banned by the USA in the late 1920s. However, this was before conservation classifications were put into place.

The koala is not extinct, it is not even endangered. They are considered to be "Secure".
