Hon Dr DAVID CLARK: I think the member's aware that, historically, that information was not centrally collected. We as a Government have put in place a system that no Government before has put in place. We have gone from a situation where there was only local-level activity to one where the Government has put $70 million into public health and contact tracing. We've seen the National Close Contact Service established, with a staff of more than 200, a new national IT solution set up, and we're adding surge response to increase staffing in our public health units by up to 300 fulltime-equivalent staff. That represents a huge scaling up of our public health capacity, and I want to thank all of those working at the front line for making this possible.
