I've mentioned briefly the policy settings. The Director-General of Health referred to this paper [Holds up a document] on—I think it was—Friday, when he said, "Look, we know our policy settings are good, because it's been tested by Nicholas Steyn and Shaun Hendy, and they've said, 'Yep, it's pretty good.' " A small problem there. If you have a really close look at that, one of the input parameters to the modelling is that day three testing is compulsory. That is part of our issue. If the whole policy setting has been grounded on day three being compulsory, and they're quoting from this paper, we've been working on a flawed basis. That needs to be relooked at. What are the implications for making this modelling not compulsory?
