For the information of senators: at 7.20, when the adjournment is scheduled to commence, I'll be seeking leave of the Senate to continue this until 7.55, when I have one adjournment speech to turn to. So I'm going to ask senators, particularly those not from the Greens, to be considerate of their Greens colleagues who are yet to speak, because I still have a dozen speakers on the speakers list. Senator Askew.
