Hon Dr DAVID CLARK: Currently, we're sitting at 80 percent of close contacts being followed up within two days. It is an extraordinary result considering the historic under-investment in the system. I am provided with the data as it's collated, and it is very promptly publicly available. I see no need, when it's publicly available and reported on regularly, for any particular mechanism the member might specify. As a Government, we have invested heavily in contact tracing and public health. We've done what no other Government has done before, and that is establish a National Close Contact Service. In March we announced $40 million extra for public health, and a further $55 million was invested in contact tracing in April, and that data continues to speak for itself—80 percent in two days currently followed up, and that is an extraordinary effort when we consider the historic neglect of that service.
