Senator WHISH-WILSON (Tasmania) (14:20): President, before I start—or before you start the clock ticking over, and I'm sorry if I've missed it—I just wonder if we could acknowledge the visiting New Zealand delegation of parliamentarians in the chamber today? The PRESIDENT: Thank you, Senator Whish-Wilson. I do acknowledge the visiting delegation from New Zealand. Welcome to the Senate. Honourable senators: Hear, hear! Senator WHISH-WILSON: They are missing the Greens, but they're still very welcome! The PRESIDENT: Now to your question, Senator Whish-Wilson.
