No predators that will worry cattle in this area. Sheep producers do have problems around here with foxes and the odd feral pig that will take out lambs.

The only major predator that worries livestock in Aus are wild dogs (dingoes or more of a problem are dingo crossed with hunting dogs that are lost/abandoned by pig hunters). They tend to breed in more remote country such as national parks, mountains and heavy timber. Thankfully not enough of that country in the immediate area for them to be a problem but don't have to go too far to hear they are around. They do prefer sheep but can attack calves as well.
