Queensland has become the final jurisdiction to roll out a QR code-based check-in app for contact tracing, adopting the Check In CBR app first developed by the ACT and subsequently adopted by the Northern Territory and Tasmania.

Dubbed Check In Qld, the app has been tested and trialled since January at 204 venues. Alternative systems that businesses are already using such as online forms, membership card scanners, online booking systems and digital spreadsheets can continue to be used.
