The Australian system is like an interest-free loan that you don't have to make repayments on until you earn above a certain threshold. The government gets the same return from a student making $60k as one making $1m through the scheme.
(Currently the amount you owe is indexed with inflation. At the moment the federal government is trying to change it to accrue interest at the bond rate (3.8%-6% rather than 2%-3%) and reduce the income level before you have to start making repayments, but it's unlikely they will be able to get the votes to get this through the senate.)
