Easily recent enough for cave paintings to be depicted and survive. The Marsupial Lion remains in the same caves are dated at between 500,000 and 780,000 years old.
My Uncle is a mango farmer near Gympie and reckons he's seen a big black cat with a long tail a couple of times but for some reason the police often fly over looking for illegal crops, so it could have just as easily been a giant penguin, chinese dragon or batman.
