One of the things they recommend is mandatory daily saliva testing, for example. This is not something that the National Party's just invented as an idea; this is something that public health experts Professors Baker and Wilson and Sir David Skegg have said for quite some time now. Again, it's not a new thing; this is something they've been saying for months now. In fact, it's in the Brian Roche - Heather Simpson report, which the Government got in September—it was finally released in December, but they got it in September. They said it should be introduced as soon as possible—ASAP—and it's something that happens in New South Wales and in lots of other countries. We think, on this side of the House, it makes sense to do it. The argument's pretty simple, which is that it's less invasive, because you're not shoving a thing up your nose, and it's quicker and it would mean that you could scale up very quickly and do much more testing than you're currently doing. At the moment, in the case of the most recent case, these workers are subject to fortnightly testing. If you could do daily testing, that would mean better identification of risk at the border and better identification of cases.
