Dingos are their natural predator. But we've killed all the dingos because dingos also eat livestock.

It's the same as with deer in Europe and America. Wolves and beers are their natural predators, but then we killed all the wolves and bears because they ate our sheep.

How do we define natural predator? Dingos are an introduced species, they've only been here around 6000 years.
