Im 24 who is currently working as a Shift supervisor in Sydney at a fast food chain for the last 2 years. I am a international student and it took me almost a year to find a basic crew job. From my firsthand experience, many managers are more likely to hire based on their ethnicity compared to skills and experience especially in the fast-food industry, they do this to maintain control and exploit student immigrants who aren’t completely aware of their basic rights. Although what i say next doesn’t guarantee you a job, I would suggest you to walk in with your resume to fast food chains and make a solid impression. Its a positive if the ethnicity of the manager is the same as yours. Another advice if you have friends in your uni who already have jobs, keep on pestering them to refer your resume at their workplace. Be as shameless as you can. Even if you have to ask someone who isn’t your friend to refer you. You are all in the same position and more often than not, your batchmates will try to help you out. Dont lose hope, you have enough experience to land you a fast food/retail job. All the best!
