All domestic undergraduate students enrolled in a degree or other award program are Commonwealth supported. Some domestic graduate students are also Commonwealth supported.
Students who are Commonwealth supported are enrolled in a Commonwealth supported place and pay subsidised tuition fees with the Australian government paying the majority of the cost.
The government pays the majority of the tuition fee and the remaining balance is the student contribution.
The Commonwealth only subsidises tuition fees for courses that are required for the completion of the specific degree of the Commonwealth supported place.
This means Commonwealth supported students cannot get Commonwealth support for courses that don't count directly towards their degree, or to repeat a course which has already been passed.
