The video showed the koala checking out an elevator before opting to descend a stairway.

Trains in the area were ordered to slow as the koala - a normally reclusive species and one of Australia's best-loved animals - came dangerously close to the platform edge.

The marsupial eventually hopped the station fence after police officers were dispatched to chase it away from the tracks.
