I'm still in high school, but even I've noticed some drastic changes in the curriculum. Firstly, we switched from a state curriculum where schools have more freedom in what they teach, to the national curriculum, where schools are more rigid and everyone has to learn the same thing, no matter how relevant or irrelevant it is. All in all though, the national curriculum is better as there are a wider range of subjects in the in lower grades.
I started preschool when the year I turned 5 (I was 4 for the majority of the year). It was all focused on play time and arts and crafts and imagination, and I could only count up to 10, write my name and read basic sentences. The year I started year 1, it was Prep instead. They could read and write and do sums by the end of the year. They also started a year older than me. By the time they were in grade 3, they could do exactly the same things as I could when I was in grade 3, although, I think it would be beneficial to be a year older in later grades.
My cousin just finished grade 2 on the national curriculum. She was in a pilot program where instead of books, they learn fully on iPads. Her handwriting isn't as good as most kids her age, and she is iPad-obsessed (though not as much as other kids I know...). They are learning coding, which, is an increasingly important skill (I can only set up a basic HTML file), but it would be just as easy to have an hour-long IT class each week. I think that it's all right to use computers for assignments, but not much else, from about grade 6 or 7 just to practice handwriting and spelling and whatever else one may learn from writing by hand.
I think that education is changing with the times, the curriculum is getting better, the Prep grade could just as easily be play time, and computers are used way too much.
Australia focuses on the Arts and Sports sides as well as the academic side, and, for as long as I remember, it's always been like that.
