Senator WATT (Queensland—Minister for Agriculture, Fisheries and Forestry and Minister for Emergency Management) (14:18): I assume that Senator McKenzie has been following this. If she has she would know that the sanitised foot mats started being installed in international airports on Monday this week, and that was completed yesterday. I might point out, by the way, that this is the first time in our history that we have seen sanitised foot mats put across every international airport in the country. We never saw the former government do this in any airports when there were outbreaks in Vietnam, in China, in Indonesia, in Malaysia, in South Africa and in every other country. Senator McKenzie: My point of order is on relevance. I was very clear in my question. Now that he's found the numbers for passengers on 5 July—and I'd also like to thank his staff for that—how many of those tens of thousands of passengers returning from Bali have actually been treated? It's not if the mats are rolled out or not. How many passengers have actually gone through appropriate biosecurity measures at our borders? The PRESIDENT: Thank you, Senator McKenzie. I'll allow Senator Watt to continue to answer your question. Senator WATT: It is unfortunate that Senator McKenzie didn't stay for the entire briefing that I just provided to all MPs. If she had done that, she would have heard one of our biosecurity officials say that the answer was a hundred per cent. A hundred per cent of passengers have been walking through sanitised foot mats. The— The PRESIDENT: Senator Watt, please resume your seat. Senator McKenzie? Senator McKenzie: I thought the questions were very clear, simple—one sentence apiece. The question is— The PRESIDENT: Just a moment— Senator McKenzie: Relevance, Madam President. The PRESIDENT: And I've answered that. Senator McKenzie, please resume your seat. Senator Wong? Senator Birmingham: You can't take a point of order on a point of order. The PRESIDENT: Senator Wong, please resume your seat. Senator McKenzie, I understood that you took a point of order on relevance, thank you. We will allow— Senator McKenzie interjecting— The PRESIDENT: No, I've taken your point of order. Please resume your seat. Senator McKenzie interjecting— The PRESIDENT: Senator McKenzie, I've asked you to resume your seat. Senator Watt, the question was how many passengers—if you could continue. Senator WATT: Well, I've answered the question. A hundred per cent have done so. And I might point out that, when this outbreak got to Indonesia, the former government put down no sanitised foot mats and had no passengers walking across them, absolutely— The PRESIDENT: Order, Senator Watt! Honourable senators interjecting— The PRESIDENT: Senators, before I call Senator McKenzie— Honourable senators interj ecting— The PRESIDENT: Order! Senator McGrath interjecting— The PRESIDENT: Senator McGrath! I will point out that the level of interjection is disorderly and I would ask you to respect the person asking the question and the person answering. Senator McKenzie, your second supplementary?
