New research has found Australia is one the most expensive places in the world to go to high school.

Data collected by the The Australia Institute found the cost of going to high school is driven by the 'unusually high number of Australian students who go to private schools and the unusually high prices of those private schools'.

A report claimed the average Australian family spends $4,967 each year to put a child through high school, almost four times the OECD average of $1,262 - which looks at prices across 38 developed nations.
