I haven't heard University of Adelaide mentioned amoungst all of this,
TER for entry to Law at Adelaide is 95, so entry isn't exactly easy! Australia's third oldest Law School (behind Sydney and Melbourne), and (correct me if I'm wrong) but, given that Sydney and Melbourne no longer offer Law to new undergraduates, would make it the oldest in terms of Law undergrad courses. Adelaide is also a member of the 'Group of 8', I am doing the LLB programme this year there so will let you know what it's like.
I suppose when deciding on what law school to go to convenience and lifestyle play a part in which Uni to choose.
