In Australia for citizens, the government subsidises around 75-80% of the cost of university, loans are through the government and are interest-free (just indexed for inflation once per year), and payments are based on income - no payment required at all if you're earning less than AU$51k/year, and payment rates vary between 1% of your income at $51k/year to 10% of income for $151k/year or higher.
