International students in Australia on a valid student visa can work for up to 20 hours per week while school is in session, and there is no limit on the number of hours an international student can work during recognized school vacations. A work week in Australia is considered to be Monday through the following Sunday. Although they are allowed to arrive in Australia up to 90 days before their course begins, students are not allowed to begin working until after their courses have begun.

The 20-hour-per-week limit does not extend to any work the student is required to undertake as a component of his or her studies or training. Volunteer and unpaid work, however, does count towards the 20 hours. If an international student works more than the Australian restrictions allow, his or her visa may be cancelled.
