What eats koalas?

There are few natural predators of the koala. Young koalas are vulnerable to owls or pythons. These attacks rare and are insignificant compared to the human related threats and impacts. The main predation of koalas these days comes from introduced feral animals like the fox and from domestic pets. Dogs in suburban areas are particularly dangerous, attacking and killing koalas.

Goannas, dingoes, powerful owls, wedge-tailed eagles and other birds of prey, pythons, and foxes all eat koalas, particularly young ones.

The quoll is the only native carnivorous mammal capable of climbing trees to get to koalas. However, a quoll will not take on an adult koala; nor will it challenge a mother koala for a joey carried on her back.
