<P> The invading nation is never specified in the books ; in fact , no nation in the world meets the criteria laid out in the series , most likely by deliberate intent of the author . Likewise , no parts of the war outside Ellie 's immediate perspective are covered ; the reader is not informed exactly how much of the country is under enemy control , or how well the war is going for the Australian military . However the invaders are described in the series as a coalition of highly populous South Asian nations seeing the vast underdeveloped spaces of Australia as a way to tackle their overpopulation ( Most likely Indonesia , Malaysia and the Philippines ) and the series features multinational colonies of enemy civilians being set up in conquered territory . Its important for context to note that at time the series was written starting around 1990 and peaking in 1995 , 2000 and 2013 there was ever increasing waves of economic migrants and asylum seekers or ' boat people ' attempting to reach Australia from neighbouring pacific countries leading to the controversial creation of foreign detention centres known as the Pacific Solution . </P>
