Sugarloaf Rock in Cape Naturaliste cat

Thought I would send you an email about an animal I saw yesterday.  We were driving down to Sugarloaf Rock in Cape Naturaliste yesterday afternoon and this big cat?? .....  ran across the road in front of the car.  The sun was behind it so couldn’t see the colour but was about as long as my car is wide (corolla) including the tail.  I had a instantaneous gut feeling that it may have been a Tasmanian tiger, but honestly it was so quick, I don’t know.  I do know it was bigger than a feral cat and its head seemed more pointed than a cats.
So, not sure what it was, but has made me rethink about what might be in the bush when I go for a walk on my own!!
Let me know if you have any thoughts or have had any other reports from this area.
