A thriving underbelly of exploited migrant workers exists in Australia, in part due to fears that those who speak out could be deported.
A report by Unions NSW, released on Monday, showed more than 60 per cent of job advertisements reviewed in the nation's top eight industries offered illegal rates of pay.
Most of the 7000 job ads surveyed for the report were in a foreign language suggesting many workers are being taken advantage of by those within their own diaspora communities.
