Since invasion and subsequent colonisation, Australia has a history of preferring and privileging people who have white skin. As I have remarked elsewhere:
Whiteness in its contemporary form in Australian society is culturally based. It controls institutions, which are extensions of White Australian culture and is governed by the values, beliefs and assumptions of that culture and its history. Australian culture is less White than it used to be, but Whiteness forms the centre and is commonly referred to in public discourse as the ‘mainstream’ or ‘middle ground’ (Moreton-Robinson 1998:11).
