- The main predators, which are mostly a problem to young koalas, are dogs, foxes, feral cats and dingoes (the latter are not common in most places where koalas occur). Rarely, goannas and pythons may predate upon them but often their ranges don't overlap. Young koalas may also be taken by snakes and various birds of prey such as hawks, kites, Powerful Owls and Wedge-Tailed Eagles.

Man also drives cars without regard for wildlife, allows his unsupervised pets to maul native wildlife, causes bushfires and even engages in torturing harmless wildlife.

Various animals including dingos, dogs, foxes and cats will also take them when possible and smaller koalas can be taken by snakes, and larger birds such as eagles, hawks, kites and falcons, etc
