Aussie study shows each immigrant = A$250,000 more to the public purse

Sydney Morning Herald story

According to some mob called Access Economics, an immigrant benefits the Australian state on average by 250,000 dollars. Apparently, 15-year olds are the best value - unsurprisingly, refugees get the lowest grade in this rather cold-blooded calculus, averaging only A$111,000. So - how much cash are the Australians spending on scouring the seas for immigrants in order to ship them to jail? I wonder why I've never heard of a similar exercise for the Home Office...don't let the facts get in the way of a good prejudice, eh.
