Australia has an extremely weak curriculum.

In most subjects, students will be several years behind their peers in the US or UK. There is a small degree of catch up in the final two years of high school, but in general Australian students will have a much narrower understanding of a lot of subjects than other western graduates.

Languages aren’t emphasised strongly enough, the English curriculum is pathetic, history is way too narrow, math is too slow a burn, the curriculum needs to be pushed up by several years, sciences are okay.

I studied in Australia K-6, at a US curriculum school in a different country 7-9, Australia 10-11, Italy (with Italian curriculum) final year.
