The blacks [of the Bloomfield River, Queensland] say that they have watched this animal's mode of attacking the kangaroo. It only does so when its victim is isolated from its mates and then only by stealth. It keeps at a distance from its prey until it can frighten it by suddenly rushing towards it, uttering screeches. As soon as the kangaroo turns its back or is in the act of jumping away, the cat springs on its back and crushes the base of its skull in its jaws, which the blacks describe as very powerful. I have never seen this animal myself, but I have seen its tracks, which are very similar to those of a large dog and seem to be provided with long claws. The blacks describe it as about the size of a bulldog with long brindled fur and very large eyes. They are frightened of it and will not go near any cave or hole where they think one might be, as they say it does not hesitate to attack a man and often kills their dogs. [ - Robert Hislop]
