Because of a differing of political beliefs Australia has become divided into two countries, to the south consisting of New South Wales, Victoria, South Australia and Tasmania is now Greater Australia and the rest Queensland, Western Australia and The Northern Territory is now Northern Australia. The north is prosperous while the south because of its devotion to the over encouragement of doubtful environmental theories and the near impossible to administer form of government is falling further and further into debt and dissolution. One or Ron Smith as he is now known is the first refugee from the south to arrive in the north where he is slowly learning that country's way of life and fitting in mostly to his finding the love of his now fiancée Professor Gwen Carstairs and the mixing with her friends. In the west of New South Wales there is an area which Greater Australia has bequeathed to First Nation People to live in and resume their traditional lifestyle, because of the removal of all white people benefits and improvements these people at first great suffer and endure many deaths because of their difficulties to reintroduce themselves to their ancestors form of living. Those who do are now living in under near stone-age conditions. They have become known as The Wildmen. The north has gained approval from the United Nations and limited approval from the south to send an expedition to these people to assist them and study their way of life. This has been organized by Carmody Ellis a brilliant person within the northern public service and in doing so has gathered up just about all the best in their fields to form the personnel in the expedition. Because Ron lived with the Wildmen in his trip to the north and knows their ways he is included along with Gwen. All is now prepared and the Expedition is ready to depart.
