AFAIK New South Wales is only one State in Australia so the headline could be better?

But given that public teaching is universal at least in average and bellow areas, doesn't this imply that teachers can only afford to live in ~10% of NSW or are salaries nonuniform such that teachers in an expensive place can afford to live in a place where the local teachers can't afford to live?

Study was based on graduate salaries that are uniform, so most of Sydney would be unaffordable to new teachers.

As a new teacher in NSW you often get too much of a say where you'll start teaching as well.
