Surrounded by the Indian and Pacific oceans, Australia is separated from Asia by the Arafura and Timor seas. The world's smallest continent and sixth-largest country by a total area of 7,692,024 square kilometers, Australia is considered as the world's largest island. Its land size is 5 times bigger than the islands of Indonesia combined with only less than one-tenth of the population.
In Alex's previous life, millions of Indonesian survivors were gathered among their country's 5 Doomsday Pillars, in contrast to Australia's 28 Doomsday Pillars spread out all around the continent, but with significantly less survivors. Many of the Australian pillars were left unclaimed by its survivors. When this fact was uncovered by the Asian survivors years after, it was already too late. Because the Australian continent was heavily infested by dangerous mutated animals and beasts. It was then categorized as an abandoned zone.
