In an ideal world we would have an equal number of facilities of exactly the same size, and we would have exactly the same number of people coming into the country every day. Then we could manage the system very efficiently. That, of course, is not how international travel works. So we try and align the release of managed isolation and quarantine vouchers with international flight schedules to make the system as efficient as we can, but when we fill up a facility over 72 hours, at the end of 72 hours if it's not full it gets closed off, and there's some inefficiency there. But the upside of that is that the risk of people towards the end of their stay coming into contact with people at the beginning of their stay is, of course, more or less completely removed from that. So from the public health viewpoint it is worth that change.
