Hey Pink!
im heading over myself next week for the year & i was thinking the same `coz the last few months all ive heard about is how theres no point going over, no jobs - people ringing into radio shows complaining couldnt afford to stay out there!
if you have your heart set on going and really want to stay out there guaranteed youd find a job, if its not in retail youl find bar work to get you through or fruit picking (just follow the seasons around) therel always be work..maybe not the preferrably work but once in a lifetime experiance and i think do it at least uve tried!!!
