I'll be doing the same on Living Away From Home Allowance and Rent Assistance payments. Of course, I'll be getting the Centrelink scholarships that they hand out to us poor kids... and the small scholarships that I do have already will be spent on necessities such as a laptop, clothes, sheets etc. [although a new scholarship in on the way].
I've already worked out that I'll have $110/fortnight left from Centrelink payments for food and other expenses (bills, rent, internet etc payed for)... and that is meant to buy food and phone bill once a month.
It will be hard, but I'll have more scholarship money on it's way to rely on, and also I'll be getting a casual job. Of course it's hard, but if you've already been living in a low-income family with Centrelink payments anyway, you'll be used to it.
