There are different types of student visas for Australia depending on studies (eg: English language course, graduate degree, vocational training, higher education, etc.) that you are planning to undertake. You need to have enough fund to cover the cost for tuition fees, living expenses, study related other expenses, and travel expenses for the entire duration of your course. As a student, you can work part time while studying in Australia. And there are plenty part time jobs available to students. But it is generally not possible to cover the total cost of your education from work.
