Senator McGrath, seriously! Order! Senator Cash and Senator Wong and Senator Ayres, come to order! Senator Cash, this started with an ongoing barrage of interjections by you. As I've said before, I do allow leaders in this place some leeway, but, in the end, I called you to order, and you continued the disorder. I said on Monday that name-calling in this place is out of order. Today, in the space of about two minutes, there's been a barrage of name-calling. It is unacceptable; we are all adults. I expect respectful behaviour. Minister Watt.
