Senator HANSON-YOUNG (South Australia) (14:46): My question is to the Minister representing the Minister for Immigration and Citizenship, Senator Ludwig. I refer the minister to recent reports that the Indian-based transnational energy and mining company, the Adani Group— Senator Chris Evans: Mr President, on a point of order: Minister Ludwig does not represent the Minister for Immigration and Citizenship. I assume it is a question to Senator Lundy in her capacity as the minister representing the immigration minister. I want to be clear. Perhaps you could ask the senator to start her question again, Mr President. The PRESIDENT: The point of order is correct. You are wishing to direct your question to Senator Lundy? Senator HANSON-YOUNG: That is right. Honourable senators interjecting— The PRESIDENT: Wait a moment, Senator Hanson-Young, you are entitled to be heard in silence. Senator HANSON-YOUNG: Thank you, Mr President. I thank Senator Evans for pointing that out. My question is, indeed, to Senator Lundy. I refer the minister to recent reports that the Indian-based transnational energy and mining company, the Adani Group, has brought a foreign workforce to Australia on incorrect short-stay visas with restricted work rights with the full knowledge of Australian immigration officials. The company was later permitted by the immigration department to transfer this workforce onto the correct 457 work visas without them having to leave the country, as they would under any other circumstance. I ask the minister: when did any official from the department of immigration, or indeed the minister's office, first become aware of the arrival of Adani's foreign workers on incorrect visas?
