What Sydney's doing
NSW is leading the way in Australia with its effective contact tracing tools. As at 23 November 2020, customer check-in at businesses must be completed using electronic methods, such as a QR code. Digital systems are contactless, safe to use and and greatly assist NSW Health contact tracers. The NSW government is offering a Service NSW COVID Safe Check-in tool free to registered businesses.
