Senator CASH (Western Australia—Assistant Minister for Immigration and Border Protection and Minister Assisting the Prime Minister for Women) (14:52): I thank Senator McKenzie for her question and I acknowledge her longstanding interest in ensuring that the rights of workers are protected. This government has a longstanding commitment to compliance in the immigration system and to ensuring that at all times the highest levels of integrity are maintained. I can advise the Senate that on Wednesday, 27 May 2015, a national day of action was held, leading to the detention of illegal workers and the gathering of crucial intelligence. The immigration and border protection portfolio, in conjunction with the Fair Work Ombudsman, staged Operation Cloudburst, targeting the fraudulent use of temporary visas and unscrupulous practices by employers and labour hire contractors. Eleven operations were conducted in all states, also involving state and federal police. A total of 38 illegal workers were detained during Operation Cloudburst. This unprecedented crackdown on illegal working and on the exploitation of workers sends a very clear message to those doing the wrong thing. This government has made it very clear that we will not put up with unscrupulous employers and labour hire companies blatantly flouting the law and allowing overseas workers to work illegally in Australia. Operation Cloudburst supports the government's announcement of the establishment of Taskforce Cadena to address allegations of fraud and worker exploitation involving temporary visa holders. Opposition senators interjecting— The PRESIDENT: On my left! Senator CASH: As well locating and detaining 38 illegal workers, the operation has led to the collecting of important intelligence. The intelligence will form the basis of the taskforce work going forward and will potentially lead to further investigation and possible prosecutions. The penalties for employers who flout the law are well known and should not be taken lightly. This government will be as tough on those seeking to exploit our workplace laws as we have been on those who seek to exploit our borders.
