Formal institutionalised inequality is where the government imposes regulations that benefit the majority of society but may have adverse affects on minor groups involved. Law reform is a remedy but often it goes too far, such as Affirmative action in terms of women.
Like ms. 12 said, Aboriginals are the minority group and unfortunately, although it is not intentional, there is a sense of injustice that is evident but if reformed will also affect the rest of society as a whole.
It's a bit of a catch 22. They just have to try to minimise the impact, rather than overhauling the whole system.
Good Luck. The HSC is looming for us all.
