Australian Plate south, is now being torn apart along the transform boundary marked by the Alpine Fault. 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. The southerly side is a divergent boundary with the Antarctic Plate called the Southeast Indian Ridge (SEIR). 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
Bali over Bali began in the 1840s on the island's north coast, when the Dutch pitted various competing Balinese realms against each other. In the late 1890s, struggles between Balinese kingdoms in the island's south were exploited by the Dutch to increase their control. In June 1860, the famous Welsh naturalist, Alfred Russel Wallace, travelled to Bali from Singapore, landing at Buleleng on the north coast of the island. Wallace's trip to Bali was instrumental in helping him devise his Wallace Line theory. The Wallace Line is a faunal boundary that runs through the strait between Bali and Lombok. It has
