Beer: $160 (Approx $20 for half a carton, 2 nights a week, or a full carton for the weekend).
Rent: $200 (Housing trust houses, they're crap but you can make them look half decent if you work hard enough).
Food: $100 (Only used to sobre yourself up after a night drinking).
Utilities (trash, water, sewer): Free at housing trust houses
Cable + net: $10,000 (australian broadband is so crap!)
Gas/Car maintenance: In my town everythings walking distance anyway.
And 2 people together can easily get that much on the dole. Except the broadband costs (but in Australia, even a millionare probably couldn't afford decent broadband :P)
