The Immigration Department is reviewing Wilson Security's lucrative role at the Manus Island and Nauru offshore detention camps following allegations it was secretly controlled by Hong Kong billionaire Thomas Kwok, who is serving five years in jail for bribery, and his brother.
Wilson Security has denied allegations that the brothers concealed their ownership and control of Wilson after the claims emerged as part of the Panama Papers, the leak of millions documents from law firm Mossack Fonseca, based in Panama.
