Senator McALLISTER (New South Wales—Minister for Emergency Management and Minister for Cities) (14:24): My view is that Australians deserve better from their public representatives than stunts. The truth is that the message I give to people who are thinking about the environment is that the only way that environmental change has ever occurred in this country is through Labor governments. Senator Hanson-Young: You can't be trusted. The PRESIDENT: Minister McAllister, I'm sorry. Please resume your seat. Senator Hanson Young, I ensured that you were heard in silence. It's taken me quite a long time to get control of the chamber, and the minister will equally be given that same respect, and she will be heard in silence. Minister McAllister. Senator McKim interjecting— The PRESIDENT: Minister, please resume your seat. Seriously, Senator McKim, that is very disrespectful towards me and the order that I am trying very hard to maintain in this chamber.
