Be sure to keep your car doors closed during a hot day in Australia, or you could end up with a koala as a new carpool buddy.
That's exactly what happened to South Australian winemaker Tim Whitrow.
Whitrow had left the doors open and the air conditioning on in his parked car so his dog could get in and out of it while he briefly went to check on the grapes at his family's vineyard.
When he returned there was a surprising new passenger in his vehicle.
"As I was moving to another part of the vineyard, I noticed that someone else was also in the car enjoying the air-conditioner," he wrote on his Facebook page on Sunday.
Whitrow filmed the encounter, showing the curious koala crawling around in the backseat of his car, with his slightly confused dog looking on.
"This is what happens when you leave your car doors open in a vineyard; koalas jump into your car," Whitrow said in the video.
Whitrow decided to drive the koala to a nearby scrubland to release it back into the wild.
When he parked the car to let the marsupial out, the stubborn koala decided to instead climb onto the front seat to enjoy the air conditioner even more.
Eventually, the koala was coaxed out of the car, but not before leaving several gouge marks across the car's dashboard.
"It took a fair bit of convincing to get the feisty little fella out," Whitrow said on his Facebook page.
