Southern boobook age. 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. Juvenile southern boobooks are at greater risk after bushfires and have perished after being tangled up in dodder ("Cassytha") or bidgee-widgee ("Acaena novae-zelandiae").

Australasian Films Australasian Films Australasian Films, full name Union Theatres and Australasian Films, was an Australian film distribution and production company formed in 1913 that was wound up in the 1930s to merge into Greater Union. The Union Theatres and Australasian Films dominated cinema in Australia in the 1910s and 1920s. In 1912, West's Pictures merged into Amalgamated Pictures, and then Amalgamated Pictures merged with Spencer's Pictures to create the General Film Company of Australasia. The following year this company combined with the Greater JD Williams Amusement Co, a large exhibition and film supply outfit, to create Union Theatres and Australasian Films.
