Work in hospitality and study at the same time
If you come with the student visa, you will have the option of combining your studies with a part-time job (20h / week), which is more than enough to pay for your accommodation and meals, or even to get an extra money to travel for the country. For these cases, a good option is to work in hospitality in Australia.
Many international students try a job in hospitality in Australia since in terms of schedules, it is quite compatible with their classes. In addition, the salary is not bad, around 17AUD / hour.
