Thing is, England's education system does seem to have delivered significant improvements over the past 20 years - it is one of the few areas of real progress in modern UK governance. And it's delivered those improvements by focusing on things like phonics and content-rich curricula as well as tighter assessment, and by improving STATE SCHOOLS, not by messing about with structural stuff ("More grammar schools!" "Bring back assisted places!" etc.).
I suggest that we all focus on stuff that has a proved track record of working (phonics, rigorous maths, content-rich approach, proper exams), rather than wasting time on stuff that does not appear to have any particular effect.
I like and admire Australia as a country in very many ways (it's a wonderful place, and the UK could learn a lot from Oz in all sorts on non-educational fields), but its educational standards are generally less good than the UK; I see absolutely no evidence that its state-subsidized "semi-private schools" have actually done anything to improve overall results. The only data I've seen suggest that they are a waste of everyone's money because after controlling for parental income, the "private" (actually semi-private) kids don't perform any better than the 100% government-funded ones. Essentially, large quantities of state money and parental money are being spent on "posher uniforms and slicker-looking facilities." "Poundshop private schools" is the name I've heard. Of course, the small number of fully private, very expensive private schools in Oz may be a little different and actually create some added value, who knows.
