This is an older article, so I can only imagine how worse it is now.

Almost half reported they had never had a job in their lives, and 15 per cent had never attended school in their birth country.

Almost 40 per cent reported not understanding or speaking English, with only 10 per cent having a university degree and just 6 per cent being qualified for a trade. Only 7.8 per cent had qualifications recognised in Australia.
