Funding all by yourself for your study with part time job is very very difficult if not impossible. It depends upon what kind of part time jobs you hook up with. Usual part time jobs like kitchen hand or room service or cashier will not be enough for you to fund your studies and yourself. There are no scholarship for international students in most of the Australian Universities. On the top of that if you are in University you will not have enough time to work outside. So plan accordingly. Don't just jump intot he wagon. Seek family support.
