Explanation:

    During the Ice Periods, Australia, New Guinea and Tasmania were linked by land bridges, forming a single continent known as Sahul. The Australoids, the first people to inhabit the region, were the ancestors of the current Papua and Aboriginal Australians, who must have arrived in Sahul 60,000 years ago.

    The following significant wave of emigrants only occurred in 6000 BC, when Austrian peoples from Taiwan spread throughout the Philippines and East Indies and arrived in New Guinea, mingling with the native Australoids, giving rise to the heterogeneous population of Melanesia. Around 1500 BC, these Austrians, the largest navigators of prehistory, arrived in Fiji from Vanuatu and shortly thereafter to Tonga and Samoa, the starting point for later Polynesian expansion into the Eastern Pacific, ending up occupying islands as far away as Hawaii to the north, New Zealand or Aotearoa (its Polynesian name) to the south and Easter Island or Rapa Nui to the east.
