Senator GROGAN (South Australia) (14:11): I thank the minister for that response. I read in the Australian this morning— Senator McKenzie: All on their lonesome. The PRESIDENT: Senator Grogan, please resume your seat. Senator McKenzie, two seconds before you called out again, I called you to order. Listen in silence. Senator Grogan, begin again and start the clock again. Senator GROGAN: I read in the Australian this morning that Liberal MPs were ambushed over Mr Dutton's plan for new divestiture powers and are concerned that the policy will force up prices at the supermarket. Can the minister please tell the Senate: what are the best ways to ensure Australians pay a fair price at the checkout? Senator Cash interjecting— The PRESIDENT: Senator Cash! Opposition senators interjecting— The PRESIDENT: Order on my left! Senator Gallagher interjecting— The PRESIDENT: Order, Minister Gallagher! Senator Colbeck interjecting— The PRESIDENT: Go right ahead, Senator Colbeck, after I've called order at least four times, and completely ignore what I said! Senator Grogan, second supplementary? Oh, you've finished? I beg your pardon. Senator Ruston. Honourable senators interjecting— The PRESIDENT: Oh, sorry. This is what happens when you are so disorderly. Minister.
