With over 1000 daily cases in NSW and more than 700 requiring hospital care – affecting other important procedures, please consider utilising the Exposure Notification system built into iOS and Android to help detect cases that manual contact tracers can’t find. This isn't a replacement for contact tracers but another proven tool to help save our grandparents, parents, siblings and children. https://developer.apple.com/exposure-notification/
