The ape, a 27-year-old female named Karta, jammed a stick into wires connected to the fence and then piled up debris to climb a concrete and glass wall at the Adelaide Zoo.
Peter Whitehead, the zoo’s curator, said: “You’re talking about an animal that’s highly intelligent.
“We’ve had issues with her before in normal day-to-day operations where she tries to outsmart the keepers. She’s an ingenious animal.”
Mr Whitehead told reporters that Karta sat on top of the fence for about 30 minutes before apparently changing her mind about the escape and climbing back into the enclosure.
“I think when she actually got out and realised where she was … she’s realised she shouldn’t be there so then she’s actually hung onto the wall and dropped back into the exhibit,” he said.
