I think the answer to that lies in the fact that there is actually no evidence that we were supplied—and it is in the committee report that we did ask for some reports that were mentioned in relation to Australia's minimum sick leave requirement and how that's increased their productivity; that was never supplied. A lot of the advice and a lot of the speeches that we've heard talk about anecdotes and stories that they've heard, but actually I want to ask the Minister a specific question: what reports or evidence has he relied on that he can point us to, that we can go and look at, that show a substantial increase in productivity that would offset the costs of the extra sick leave? So that's somewhere I wanted to go today, to ask him about that. I've got a few more questions, but I'll let the Minister answer that one first, and then perhaps we can carry on.
