Big Cat Sightings in Australia...

Has anyone heard or read anything about these?

I've been doing some reading on them at a couple of cryptozoology websites about them, mainly Rex Gilroy's Mysterious Australia site(sorry, don't have a link handy but will dig one up asap). There have been several photos and even some film shot of these animals.

After looking at the photos and stills of the footage, I am convinced that the animal in question is nothing more than an escaped black panther or black jaguar, or possibly even a HUGE feral cat. It is fairly obvious when looking at it, though some have the idea that it could be a surviving marsupial cat(Thylacaleo). While I am not an expert, I don't agree with this at all. I am usually not a skeptic, but this one is in my opinion a little loony and reaching a bit too far. From what I've seen of fossil remains of the Thylacaleo, it does not have a massive resemblance to a modern big cat, though there are similar features, they don't add up to me(but if you don't want to wait try an internet search for big black cat sightings).

Anyway, I will get the links up as soon as I can, but any thoughts or ideas in the meantime?
