The reason we have the testing regime at the border is to make sure that people who are working on the front line, who are coming into contact with people from overseas who have COVID—and we know that there are more and more people arriving in MIQ from places like India, for example, who have COVID. The reason we make them get tested is to make sure that they're working there without it, so that they don't spread it like case A did to case B, who spread it to case C. Now we're all hoping beyond hope that this cluster does not spread any further. So that's why we have the testing regime. But the quid pro quo of establishing the testing regime is that the Government goes and checks that people are being tested.
