Indian mining giant Adani has refuted claims it's cheating the migration system with its foreign workers.
Reports by The Australian claim a company review by Ernst & Young found none of Adani's foreign workers were properly registered or accredited to work as engineers in Queensland.
According to The Australian the report also claimed most foreign workers had been wrongly imported on short-stay 456 visas instead of the correct 457 system.
In a statement today an Adani spokesperson told Australian Mining it did not have workers on 465 visas.
"All employees from overseas that are currently employed in the Australian business are employed under 457 visas," they said.
"Adani Mining ensures that it is in full compliance with the statutory requirements of the 457 Visa scheme including the remuneration, training and sponsorship obligations."
In the statement Adani also reinforced previous comments it was not currently pursuing an Enterprise Migration Agreement and was "complying with all statutory obligations".
