YES !

While on a student visa, you may work up to 40 hours per fortnight during term time, and full-time in the holidays. The visa is automatically issued with permission to work, although you’re not allowed to begin working until your course has started, and should not rely on work in order to support yourself or your family while in Australia.

If you’re studying a master’s by research or a PhD you don’t have any work restrictions. Keep in mind that any work required as part of your course is not included in the limit. Voluntary/unpaid work is also not included in the 40-hour limit if it’s genuinely voluntary, for a non-profit organization and for the benefit of the community.
