You need to conduct an online research about Auburn/Sydney (just make a general idea about it, for instance it is an immigrant area, families income etc..)
And you need focus on Auburn Girls High School and Auburn Public school (for exp. How immigration policy has effected those schools in last 20 years, how the parents of the students standards of living etc…)
Then as an immigrant area you need to specifically identify only Class and Socioeconomic status issue and the reason it cause inequality and power imbalances. Use a sociological theoretical frameworks to explain how power is operating in your issue ( Marxism- Cultural Capital).
Then you need to analyse how these issues fit into the broader Australian and global discourses and give specific examples of how power and inequality play out in educational contexts.
