I don't really know much about the rest of the country but this city is nothing like it was. most of the public schools here I would want nothing to do with (I know there are exceptions like willetton and shenton college etc).
It's funny how different perceptions can be. For me, public high schools in Perth that I wouldn't have wanted anything to do with 20 years ago are now the very model of respectability. I know the public school I went to has improved beyond recognition. All associated with the "gentrification" of their neighbourhoods where previously they were outlying suburbs now they are middle ring. I can well remember being of ethnic extraction back then could be a frankly terrifying experience in the school yard and next to none of the teachers cared about it.
There are quite a few public schools that beat many of the private ones in Perth now and they're a lot cheaper...
But then I'm also impacted by my uni experience doing two degrees concurrently - one in Elec Eng and the other in Commerce. A LOT of private school grads started with me (would have been over 2/3 of the intake) due to their artificially high tertiary entrance scores courtesy of all the coaching but without someone to hold their hand in such a tough course they fell by the wayside pretty quick. Less than 10% of my peers actually graduating at the end of 5 years would have come from a private school. These results were pretty well mirrored across the "standard' eng grads as well, just to a lesser extent. Anectdotal discussions with more recent grads have indicated nothing much has changed in that respect. First year lectures were held in large ampitheatres and final year lectures in small classrooms...
