All was quiet at 3.20am on Monday April 20 in the emergency department waiting room at Hamilton Base Hospital in country Victoria, when a surprise visitor dropped by.
The koala, probably from a nearby park, just thought he'd drop in to say hello to the emergency department staff who were in the middle of a slow night shift.
"The staff there aren't really used to getting visitors of the four-legged variety so they got quite a shock", Western District Health Service CEO Rohan Fitzgerald told BuzzFeed News. "But they just kept an eye on him and let him go and have a look around."
Mr Fitzgerald says the koala just explored the waiting room and couldn't have gotten near any sick or sleeping patients.
