I confess that one of the reasons we left Australia when we did was concern over the education system in Queensland. Our DSs would have almost certainly have gone private (as someone said, the private schools educate 30%+ of the population, which translates as 'fewer in the country, many more in middle class suburban/city areas') BUT of the six 'local' private schools on offer on the Sunshine Coast, all were of a religious persuasion: Two Christian Fundamentalist (Creationism, the myth of evolution/fossils are the work of the devil), the inevitable Catholic, an Anglican (usually the most expensive), a Lutheran and a Methodist. Oh, and not far away, an obscure Indian Sect/hippy school.
The local state highs were overcrowded and suffering from the social problems that happen when you 'cream off' the middle class kids. A friend is sending her DD to one of the better state highs, on the Music Programme (as opposed to the -I kid you not- 'Surfing Programme'). The entry requirement for Music? Having played a musical instrument in primary. No grade or level required.
A principle issue for us was also the emphasis on sport. All the glittering prizes appear to go to kids who are good at sport rather than good at science. Another friend told me it reminded her of 1950s white South Africa!
Here, in the UK, whilst I concede we are fortunate to have been able to buy into the catchment of excellent state schools, I am pleased with the education my DSs are getting. I think that here we are good at 'doing ourselves down' whereas some countries cannot endure any criticism of their way of doing things, hence you will always hear, in those 'Relocate to the Sun' TV shows featuring Oz that 'the education system is excellent'.
Not necessarily.
