Data from Finder has revealed once all costs, such as tuition fees, camps, excursions, sporting equipment and transport costs, are taken into account, Aussie families are shelling out an average of $2,547 per primary school child per year and $4,793 for secondary students.

Australian tuition fees comprise the bulk of expenses at an average $158 annually for a primary school student to more than $12,000 for a private secondary school.

While NSW and the ACT ranked the most expensive states for private education South Australia led the way when asking for voluntary contributions from public school parents.

Primary school students were asked for $440 each year while the average secondary school asked for $978.

Here's how you could save some money.

When you're on a budget, shopping secondhand could be a parent's best friend. Find good deals at Vinnies or Salvos or check out a local secondhand book fair.

Many schools also have listings for second hand items or resales. Check your school's website or newsletter for more information.

Take stock of what your family already owns.

School bags, pencil cases, hats and shoes often come up good as new after a good wash, and taking stock avoids potentially costly double-ups down the track.

A quick and easy way to ensure parents were getting the best deal for their dollar was to compare prices from major retailers online.

Online shopping allows families to compare prices at big sales.

Some big retailers like Officeworks offer shoppers a price beat guarantee on identical items also stocked by competitors, even if the item is on sale.

Many major banks offer no-interest loans for education expenses.

NAB has revealed more than $640,000 in no interest loans are expected to be taken out in February to help cover education costs.

Loans are often taken out to help pay for costly uniforms or laptops.

The number of people taking out education loans has grown by more than 73 per cent between 2018 and 2023.

Australia-wide programs like the Smith Family's back-to-school appeal offer a lifeline for families struggling under the heavy cost of school-related expenses.

OzChild, St Vincent De Paul and other non-profit organisations often help connect families with much-needed supplies and financial assistance.

Local churches, libraries and neighbourhood houses can also offer assistance with vouchers, after school tutoring and other activities.
