On the wages of studying abroad and working on farms in Australia

Originally, Australian students were allowed to work, but there were time limits every week. There are also many foreign students who do jobs without paying taxes in order to avoid the time limit of working. Basically, the salary of overseas students in Australia is 12~ 15 Australian dollars per hour, which is 70~90 RMB per hour. Because wages are calculated by the hour, it's the same everywhere, not just the ranch.

Students who fail to pay visa fees will be reported by the school and repatriated. After repatriation, your intermediary is not responsible for you, and your payment of 158000 is equivalent to hitting Shui Piao.

I suggest you study in Australia through formal channels. If the main purpose is to make money, you can find a school with cheap tuition. But because of the high cost of living in Australia, you can only meet the tuition and living expenses under the premise of very hard work, so it is impossible to save money and send it back to China.
