Senator McKIM (Tasmania—Australian Greens Whip) (14:24): Just last week the Prime Minister said: You judge a society not just by how it looks after the most wealthy, how it looks after the Gina Rineharts of this world, but how it looks after the vulnerable. Given Ms Rinehart has added over $10 billion to her wealth since you took office, when will Labor start making her and other billionaires pay their fair share of tax so vulnerable Australians can live with a little more dignity? Honourable senators interjecting— The PRESIDENT: Order my left! Senator McKenzie and Senator McKim, order! Senator McDonald, if you care to look, I am now on my feet. I beg your pardon, Senator Davey. From the start of question time, a number of senators in this place who I have called by name have been incredibly disrespectful and disorderly to the point that I've had to stand. I expect there to be silence when the question is answered. If you can't remain silent, I invite you to leave the chamber. Minister Gallagher.
