As an addendum:
Rent in OZ (Entirely depends where your "ties" are) - For me PERTH WA.
Someone I know does Homestay $125.00 per week, ALL UP - private room, Air conditioned, INCLUDES 3 meals a day cooked for you, ALL utilities, NBN internet - unlimited. They ONLY do travellers, max stay 28 DAYS.
It is just an example - if you look hard enough you will find them too - It will consume half your Centrelink "NEWSTART" allowance. However, if you do not have other bills (Or smoke/drink), you can live quite comfortably on $130 per week "Pocket money.
