In summary, this thesis examined that the desire to remain one people without the admixture of other ‘races’ was one of the most powerful forces that impelled the colonists towards Federation and the ‘pure race’ that could be codified. Historians are in no doubt that a central policy of the movement towards Federation was the exclusion of all people considered inferior and unfit for a white country. Federation was the rationale to maintain white superiority and racial homogeneity, and subsequently the first act of the new parliament was the Commonwealth Immigration Restriction Act (1901). Racial discrimination in entry, residence and citizenship provisions were sanctified, and a unified White Australia established. This policy confirmed the racist ideologies based on white supremacy and the dominant perception of Indigenous inferiority and their low evolutionary progress.
