The biogeography of Cretaceous Australian dinosaur fauna has been characterized variously as endemic, cosmopolitan or closely related to other Gondwanan faunas. Over the past decade, a large number of new Australian dinosaur taxa have been described and included in phylogenetic analyses, allowing for new insights into their biogeographical affinities to be obtained. Here, I combine the latest phylogenies of Australian dinosaurs into a supertree that includes as many Australian taxa as possible and apply it to the construction of biogeographical networks of Cretaceous dinosaurs. The results show that the Cretaceous dinosaurs of Australia have a strong connection with South American dinosaurs and to those of other Gondwanan continents via South America. Community detection algorithms indicate that the Gondwanan continents form a community within Cretaceous dinosaur biogeographical networks. The biogeographical affinities between Australia and Laurasia detected in previous studies were largely due to the scarce dinosaur fossil record of Gondwana at that time and to the unstable phylogenetic position of Australian dinosaurs because of the fragmentary nature of their fossils. Continuing discoveries of new Australian taxa and refinement of resulting phylogenetic analyses can further deepen our understanding of the biogeographical history of Australia.
