But, basically, Budget 2020 isn't the only other significant investment that we've put in during this year, because as the conditions started to deteriorate overseas, our Ministry of Health, our Government, was watching. Basically, because we had the capacity to put those border measures in place early, we had the time to look at the evidence and put extra measures in place, because in the absence of a vaccine, contact tracing and early diagnosis are going to be the cornerstones of protecting us. So even before we announced Budget 2020, the Government, on 17 March, had announced $500 million in extra funding. What that funding was used for was to double the resourcing going into public health units, who were at the coalface of that contact tracing, setting up a national close-contact service that then coordinated that contact tracing and also looked at investigating the clusters and all those complex investigations.
