Not sure if this is the information you're after but on a recent bike ride through the bush I saw a very large black cat.
I had been sitting very still for a long time soaking up the ambience. When I returned to my bike I looked up and about 100 meters away I saw a large animal passing by. At first I thought it was a feral pig but noticed the shape of the body. It was definitely a cat.
When I measured it's height against the bushes it walked behind I estimate it was around one meter high. Perhaps it was common feral cat but if it was it was a very large animal.
The area was around 50kms north of ### NSW.
No photos I'm afraid, too quick. But there was evidence of large cat like foot prints and a very large scat which was full of feral goat and pig fur.
I hope this helps.
