As an Australian, may I point out that one of the conditions of obtaining a student visa is being able to support yourself while you are here. There is a resentment of international students who get partway through a course and then cry poor. Our university (and probably others) held a big campaign during COVID lockdowns to donate money, clothing, groceries to international students who couldn’t work and couldn’t get back home; like so many other things, there were people who thought “of course we have to help these poor unfortunate people” and others who thought “oh no, anyway”.
As an Australian, I feel that (in my opinion) while Australia is in some ways an easygoing relaxed society, there is a low tolerance for (1) people trying to game the system and (2) stupid bullshit. Australian society can also in some circles, be racist and intolerant, especially towards those who are non-white and/or non-christian.
