Oes Australia have a class system? What are the social forces that shape perceptions and realities about class in Australia?

I need to answer the essay topic question looking at the three main points of The changing nature of work (which is related to the changing nature of production & economic activity), the changing basis of the individuals sense of identity (from one based on ones work role to one based on consumption patterns or cultural affiliations, lifestyles, political agendas etc) and the changing nature of politics and the way political parties are less closely associated with class identity and class struggle. There are specific texts we must reference which I will upload
