<P> South of New Zealand the boundary becomes a transitional transform - convergent boundary, the Macquarie Fault Zone, where the Australian Plate is beginning to subduct under the Pacific Plate along the Puysegur Trench . Extending southwest of this trench is the Macquarie Ridge . </P> <P> The southerly side is a divergent boundary with the Antarctic Plate called the Southeast Indian Ridge (SEIR). </P> <P> The subducting boundary through Indonesia is not parallel to the biogeographical Wallace line that separates the indigenous fauna of Asia from that of Australasia . The eastern islands of Indonesia lie mainly on the Eurasian Plate, but have Australasian - related fauna and flora . Southeasterly lies the Sunda Shelf . </P> <P> Depositional age of the Mount Barren Group on the southern margin of the Yilgarn Craton and zircon provenance analysis support the hypothesis that collisions between the Pilbara--Yilgarn and Yilgarn--Gawler Cratons assembled a proto - Australian continent approximately 1,696 million years ago (Dawson et al. 2002). </P>
