We have the same stories here. There is rumoured to be panthers/panther near a place called Lithgow in Australia and there has been multiple sightings. Also there was footage of what looked like a panther stalking a kangaroo which was taken by a group who was camping near the area, they went back the next day and there was remains of a kangaroo. So its basically like Loch Ness monster, shit loads have seen it but no hard proof.
