Brushtail possums ("Trichosurus" spp.) and introduced cats and rats raid the nests for nestlings and eggs, and raptors such as the brown goshawk ("Accipiter fasciatus"), grey goshawk ("Accipiter novaehollandiae"), Australian masked owl ("Tyto novaehollandiae"), and probably powerful owl ("Ninox strenua") seize young birds.

The southern boobook generally preys on mice, insects, particularly nocturnal beetles and moths, and birds the size of a house sparrow ("Passer domesticus").
