How about delivering leaflets .
Not much money but would get you out and about, and give you some money over your centerlink to try and save.
Do WA have cash for cans?
Here in SA you always see people collecting the used cans and getting extra money for these.
I save all our cans and bottles, get over $100 on a regular basis which I gave to my kids.This paid for their uni books.
We were at one point paying upfront uni fees for 2 sons .(before we became citizens)
Not a great thing to have to do but would give you money for uni fees soon builds up.
I know these are not a job but could help you get the money for uni fees.
