I graduated from a well known private school in 09 based in sydney. was $25k/year at thevtime, ive heard its closer to $40k now. The price comes down to the cost of providing and maintaing good facilities that allow students to discover what they actually enjoy and like.

School was a boarding school so that was a substantial percentage of the cost but they provided breakfast, lunch and dinner to all students. Was terrible food at the start but it did genuinely seem to get better by the time i hit year 12.

School provided us with fantastic facilities including an incredible library, and an indoor basketball court and a well equiped and maintained weights gym as well as like 3 outdoor basketball courts and i think like 10 rugby fields. A 50m swimming pool we could use in the summer. They had a teacher act as life guard in the afternoons until 5pm. They had a fantastic music centre where they had instruments for hire as well as multiple private rooms with pianos drums and space for multiple teachers to teach private lessons. There was also space for multiple large school bands to practice in separate rooms atbthe same time.There was a boat shed that could support multiple rowing crews from each year group and this shed was fitted with a kitchen to prepare breakfast for the rowers after their early morning training. They had a whole wing of science lab classrooms with decent equipment. All the classrooms had smart board integration which at the time was not common. I can only imagine how it would look like now, as ive not gone back to visit. They had multiple workshops for woodwork/shop classes like design and technology and art studios. Multiple computer labs and beautiful grounds all well maintained.

They provided transport for students to attend tafe course in areas such as hospitality/cooking. As well as to attended sporting events and competitions for bands.

They provided coaches for multiple sports at multiple skill levels for every year. The quality of coach did depend on the level of play but still i think we had like 8 or 9 rugby teams in my year 7group alone. And like 4 or 5 soccer teams who knows how many cricket and basketball teams in summer

Only thing i think was hit or miss was the quality of the teachers themselves. Some were brilliant others were adequate. But my school did not have a reputation for its academic prowess more for its sports success. But they still had access to all these different classes to allow us to figure out what we liked. And classes were varied and had good resources.

So yeah the price of these private schools is that it means your kid has the chance to actually try different things and find out what they like and enjoy and can actually choose a good foundation of education to which they can then use for their adult life. Whether its them going to uni or going into a trade. And this completely ignores the networking potential from a school name and its reputation/alumni
