Sally Morgan's year of birth is 1951, the one when Paul Hasluck held the position of Minister for Territories when then he set about improvement of the government's plan of assimilation. That was he who defined the guiding principle in the following terms; he stated that it is supposed that all aboriginal people or people of mixed blood will have an opportunity to live just like white Australians do. Thus this guiding principle was fixed on the theory of "the Australian lifestyle" that preached the merits of a general culture and insisted that all ethnic minorities comply with it by accepting this as persons and by abandoning all their differences, that were closely connected to their uniqueness as part of the society.
