Classification
Some authorities claim that M. australis is a synonym of Broussonetia papyrifera, the paper mulberry. , others deny this, claiming that M. australis and B. papyrifera are separate species within the Moraceae family.

M. australis is closely related to M. kagayamae, the main difference is that M. australis has fewer, or no, palmate leaves. The majority of Morus species should be considered subspecies of M. alba, whether M. australis is a separate species, or a subspecies of M. alba has not been established. Millennia of cultivation of Morus species, and easy hybridisation between Morus species, has resulted in problems for classification.
