If this doesn't work, I suggest you send an email to the school to find out. This is the safest way. After all, what others say may not be accurate. I hope you will consider paying attention to the regulations of the Australian government. I remember that there is a study time requirement for international students' visas (I remember how many hours I searched the website of the Immigration Bureau, and I will let you know when I find it).
However, regarding part-time jobs, although it is common for blacks to have no working time limit, it is still necessary to remind the government of the regulations.
8 105 During the course, you must not work more than 40 hours every two weeks * (except for jobs registered as part of the course). * Two weeks refers to any period of 14 days, starting from Monday and ending on the second Sunday. A visa below 573 means that if you are a research graduate student, you must abide by the course assignments. )
