Is/was there a natural predator in Australia to keep their numbers in balance?

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.

For the past several thousands of years, that was mainly humans and dingos. Not so much now.

The thylacine's preferred diet was kangeroo, and they were hunted to extinction after falsely being branded chicken thieves.
