The decision to lift our alert levels on Sunday evening was taken in accordance with the plans that we developed over the course of the last year. The situation distinguishes itself from a couple of cases that we had towards the end of last year, and I think in the context of the member's motion for an urgent debate, it's important to explore that a little, because I think it helps explain exactly why we did do what we did. When we think about the cases that we saw last year, all of them we were quickly able to identify at least the location of the source—that being a managed isolation and quarantine facility or, in the case of the Defence Force worker, a particular event. That allowed us to have a great deal of confidence about the fact that our very robust systems of testing and contact tracing could manage the situation.
