Private vs Public School in Australia: What It Really Costs

Short answer

Choosing between a government, Catholic and independent school is one of the biggest financial decisions Australian parents make — and the gap is larger than most families expect. For a child starting school in 2025, the Futurity Investment Group Cost of Education Index puts the national metro average at roughly $123,294 for 13 years of government school, $193,666 for Catholic, and $350,158 for independent. That is before you even think about a second child. But "public school is free" is a myth, and the right call is about fit and value — not just the fee sticker.

The three options, and what "free" really means

In Australia, "public school" means a government school. There is no tuition fee — that part genuinely is free. What trips parents up is everything else.

The Futurity index found that at a government school in Sydney, school fees and voluntary contributions make up just 5% of the total 13-year cost (about $386 a year in levies). The rest of the money goes to:

• Electronic devices (laptops and tablets)
• Outside tuition and coaching
• School uniforms
• Excursions and camps
• Sports equipment and extra-curriculars

In other words, a "free" school still costs real money — it just hides it across the year. The national metro average for a government education is about $9,500 a year, all up.

What the numbers actually look like

Here is how the three options compare nationally for a child starting school in 2025, over 13 years (metro averages):

Location moves the dial a lot. Sydney is the most expensive city for both government ($150,323) and independent ($411,108) schooling. Perth is the cheapest capital city for an independent education at about $300,109, while Canberra tops the list for Catholic schools at $215,633.

A quick rule of thumb: each extra child roughly doubles the total. A Sydney family with two kids in independent schools is looking at a seven-figure commitment over their schooling years — before university.

Where the money actually goes

This is the part most "private vs public" debates miss. At an independent school, tuition fees are the headline number, but they are only part of the bill. At a Catholic school, fees make up about 46% of the total cost; the remainder is devices, tutoring, uniforms and excursions — the same ancillary costs government families pay, plus fees on top.

So the honest comparison is not "$0 vs $30,000 a year". It is:

• Government: about $9,500 a year of mostly ancillary costs
• Catholic: about $14,900 a year including moderate fees
• Independent: about $26,900 a year, rising sharply in senior years

A worked example: one Sydney family, two kids

Let's put numbers on a real decision.

A family in Sydney has two kids, five years apart. They compare a government school with a mid-tier independent school.

• Government path: roughly $150,000 per child over 13 years = $300,000 for two.
• Independent path: roughly $400,000 per child (a mid-range, not top-tier school) = $800,000 for two.

The difference is about $500,000. Invested instead, or put toward the family home, that is a meaningful amount — but it is not the only number that matters. A smaller class, a particular sport, a school that fits a child's learning needs can be worth more to your family than the fee gap.

How to decide as a family

Rather than asking "which is better?", ask these four questions:

1. What does my child actually need? A specific program, more support, or just a good local community?
2. What can we afford without stress? School fees that force a second job or a skipped family holiday have a hidden cost of their own.
3. What are the real extras? Add uniforms, devices, camps and tutoring to any fee quote before comparing.
4. Are we buying outcomes or fit? Research consistently shows academic results track family background more than school type.

The bottom line

There is no single "right" answer — only the right answer for your family. The key is to compare total cost, not the tuition sticker, and to choose a school that fits your child and your budget without stretching it to breaking point. A great local government school, plus the money you save invested over 13 years, can be the smartest financial decision you make as a parent.
