Thank you, Senator Cameron. In relation to the point of order, I intend at the end of question time today to rule on two matters that were raised by Senator Wong yesterday; so whether Senator Cash is anticipating what I may or may not say after question time, I don't know. Can I remind all senators to be very cognisant of the language they use in the chamber, and I have reminded ministers of this in the past. There is no point of order against the minister. Minister, you have the call.
