An international student in Australia is allowed to work part time while they study. They have permission to work up to 20 hours per week while your course is in session. However, they cannot start work until they have commenced their course in Australia. If students bringing their family with them, then dependants can also work up to 20* hours per week once you have started your course in Australia.
International students often find work in retail, hospitality and administration. They could expect to earn a $6-15 an hour, depending on the kind of work they do. They may be paid more for working on Sundays or public holidays.
