Particularly, I guess, the points of weakness, to us, are around those places where there are exemptions. We do understand there have to be exemptions, such as for diplomatic and Defence personnel, and the specific one here in the isolation and quarantine amendment order around aircrew. I completely understand that, in order for international flights to operate, there needs to be a different process or requirement for aircrew, but it would be good if the Government was able to lay out what the specific requirements are and help give confidence in that system, because it was, I believe, aircrew travelling with a shuttle driver—just that one exposure—in New South Wales that has led to this pretty substantial community outbreak that's been very, very difficult to manage. So it does just highlight that aircrew, and any sort of exemption, is a point of weakness. Whether or not people have been vaccinated, we know that they can carry the virus and transmit the virus even if they have been fully vaccinated. So it's vitally important that we ensure that we are not leaving anything open to risk.
