Order on my right!

Opposition senators interjecting—

Now on my left. I'll call Senator Green when there's silence.

Senator Watt interjecting—

When there's silence I'll call your colleague, Senator Watt.

Senator Wong interjecting—

Senator Wong!

Senator Colbeck interjecting—

Senator Colbeck!

Honourable senators interjecting—
