SA's Chief Public Health Officer Nicola Spurrier has moved to clarify the rules around checking in at work. Prof Spurrier said whether staff were required to use QR codes at work was "entirely up to a workplace" unless a business was subject to a formal health direction, because most businesses were able to trace employees quickly if required..
Prof Spurrier urged people to keep checking in – preferably via the myGov app, because it was faster and more efficient for officials to carry out contact tracing, rather than via the handwritten records. "Using the QR scan is so much better because we can automate the system and get things done more quickly. And as you can see in this pandemic, speed is really important."
