International Students

International Students studying in Australia on a student visa are permitted to undertake no more than 25% of their total course by distance and/or online learning, and are not allowed to study units exclusively in distance or online learning in any compulsory study period. In any compulsory study period, an international student must study at least one unit that is not online or distance education. If your college offers online or distance education study in a non-compulsory study period (eg. between semesters), this may be your exclusive mode of study for that period, and it will be counted against the 25% maximum for the the course.
