The Ministry of Labour will investigate a recruitment agency after it demanded an upfront fee from workers heading to Iraq.

Fijian entrepreneur Jerry Talemaitoga said his recruitment company, Bridge of Hope International, asks workers to pay a $US3,000 to cover airfares, registration fees and visas.

Talemaitoga has told Radio Australia he has already sent 150 drivers last year and 50 drivers so far this year.

However, General Secretary of the Fijian Transport Workers Union - Kamlesh Kumar said the demand for an upfront fee is suspicious.

Kumar adds his advice would be for the driver wanting to take up the offer to have things verified by authorities and see what sort of working conditions they are going into.

Meanwhile, the Legal Tribunal with Fiji's Ministry of Labour, Senivalati Kurubuabua, has told Radio Australia there have been no complaints so far, but they will investigate Jerry Talemaitoga and his company.
