Just to balance out the picture your painting of the selfish expat who is using up all of Australians resources while stumbling from one disaster to another while overseas .
Most expats do very well overseas , career wise , socially and financially . Never ask for any help while sending large amounts of wealth back to Australia , investing it into property and super and not a single cent of Australian tax payers money was used on them while they created this wealth . Over %5 of Australians live overseas . Many come back multi millionaires , stimulating the Australian economy by paying taxes , school fees and using private health . Not sure why you fear the expat so much ?
