Now, as that situation emerged, as the evidence changed, and as we came to better understand the virus, we have had to respond quickly, and under the existing legislation that has been possible. And it's true that our understanding of the virus continues to emerge. So I would push back on some statements made by the Leader of the Opposition that minimise the risk. We do better understand this disease, but we don't completely understand this disease, and it is important that we continue to take a risk-based approach, underpinned by the legislation that we have.
