Panther or Feral Cat?

Occurred on June 11, 2018 / Kanimbla, New South Wales, Australia

Info from Licensor: "My partner Steven and I were fishing along the Cox’s River, on our way home we decided to look at a new development being built nearby. On departing we noticed the large black cat-like creature. What was distinctive, was it’s long, thick and curled tail, unlike that of many feral cats we had seen before. We watched it and took videos for about 20 minutes. It prowled the side of a mountain where we stood and watched about 150-meters away."
