Senator WATT (Queensland—Minister for the Environment and Water) (14:52): Senator Roberts, I think we're all used to you and other One Nation senators asking questions that involve pejorative statements towards migrants, and it would appear that that is the intention for this term as well. How you decide to use your questions is a matter for you. The PRESIDENT: Minister Watt, please resume your seat. Senator Roberts. Senator Roberts: An unfounded imputation, President. I happen to be an immigrant. The PRESIDENT: There is no need for the added piece. Senator Roberts, the minister was describing the language with which a question was asked, so it doesn't go to imputation. Senator WATT: To answer your question, Senator Roberts, as I say, when the issue of fraudulent qualifications came to light, we took action. I was a little bit involved in this in my previous portfolio, and my recollection is that a very thorough search was done with employers who may have been employing the people involved. I will come back to you if this is wrong, but my recollection is that there was not very much evidence, if any at all, that people were being employed using those qualifications. As I say, if that's wrong, I will come back to you. We do take this matter seriously, and we will keep acting against it. The PRESIDENT: Senator Roberts, second supplementary?
