So the three that we are confirming: one is quite a significant one and the others are relatively small points of clarification. So the COVID-19 Public Health Response (Vaccinations) Amendment Order 2021 extends the vaccination requirement for our border workforce to a broader number of people. We have had in place a requirement that those working in our managed isolation and quarantine facilities have to be vaccinated in order to undertake the work. That's been in place for some time, and many of our front-line border workers have had to be vaccinated. Again, that has been in place for a period of time. We are now expanding that to a wider range of people, and that is what this order confirms. It is important that we provide the greatest layer of defence using vaccination in our border as possible. We've been working to achieve that over the course of 2021, since vaccines became available. This order extends that to a broader number of people.
