Many operators in FFNQ (not cns) and Torres Strait will give you somewhere to live, in several companies it'll come out of your pay so you won't miss it. Weekly budget consists of:
$30 worth of of bread
$30 worth of mixed 2 min noodles
$30 worth of eggs and milk
$50 worth of pasta and mince
One pub meal + schooner ($25).
The rest naturally goes on beer and songs on the jukebox (if you can get one in between bob marley and 50 cent).
Don't even think about saving anything, if you want to try, refer above budget and remove pub outing, beer, eggs and milk and probably bread too.
