Those fees are nothing compared to those of NSW.
I was surprised Melbourne Grammar(Boys) and Geelong Grammar were not on the list.
I have to somewhat agree (I go to Melbourne Grammar). The thing is, like half our year level (100 boys) are "all the way"; that is, they start in Prep at MGS (which is about 15k a year), and stay at the school for 13 years (except some go to timbertop for a year...). Anyway, out of those who started in prep, only one or two are 'top students' (academically). Virtually all of the top students come in at year 7 (which incidentally, is the year they offer scholarships for) or year 9 (another scholarship intake year).
As for the quality of education, I honestly would say that the quality is not much, if at all, better than a public school. HOWEVER, the intial image of the school makes it a confluence of many bright minds, and therefore, you are surrounded by good students (which I suppose can help bring ur level up). Really, much of the price u pay is for the peers (same with the uni's listed above like Harvard..., which actually has a very generous financial aid program; mean aid is 30k a year off price).
Another aspect of private schools is that they often teach subjects that are esoteric, and very marks-orientated. An example at our school is LATIN (number 1 subject for scaling...45 mean). So many students take it, and the school poaches the top Latin teachers in Victoria, so our scores in this subject are very high. I'm sure very few public schools (and I definitely do not refer to MHS or macrob, coz whilst they are public, they far surpass any other public schools) do any subjects for the sake of marks (out of 200 students a year level..100 do spec, 60 do latin, and next year, once classical greek starts up...i'm sure heaps will do that as well). Still, i'm not complaining - i luv the English faculty...so many 50s! and also...second highest school for 99.95s: we had 3..MLC had 4.
