I'm considering studying in Perth for a year but some people say that it's really expensive to live there. In particular, one person I'd spoken to said that food was really expensive. As someone on a student budget, I wondered whether I'd be able to survive for the two semesters needed to complete the course. I know that there's no such thing as a 'typical' grocery shop, but could someone give me a ball-park figure (AUD) for a week's grocery shopping for one? Thanks.
