Order! Senator Hume, resume your seat. I can assure senators, I am not having a question time where those on my left think it is your job to yell louder than the minister. The minister has an absolute right and should be given the same respect as the person asking the question. If you can't sit in silence, leave the chamber. But I'm giving you a warning. I will name you today. This is not a football match. It's not your job to yell louder than the minister. Senator Hume, first supplementary?
