Proof Big Cat caught on film Victoria Australia clip 1

I came across this huge jet black cat with a long tail while walking through the Victorian bush. I was standing at this water course after making my way through thick bush when some movement caught my eye across from me. I first thought it was a Labrador dog because of its size. To my amazement I realised I was looking at a huge black cat but not your usual feral cat which I have seen plenty of. This was very different from anything I have seen before. I quickly whipped out my iPhone and filmed it as best I could. This day was very windy and I think that helped muffle any sound I made as I walked through the bush.
I couldn't move forward because of the water but managed to change position and get another quick shot of it as it made its way along the tree line.
