A stronger COVIDSafe » App for Australians

The Morrison Government today announced a world-leading technology development that will further improve the « COVIDSafe » App and bolster the continued fight against the COVID-19 pandemic in Australia.

The update comes as the Government launches a new advertising campaign as a reminder that as we head into Christmas and restrictions are easing, people should maintain COVID-safe behaviours.

The « COVIDSafe » App will incorporate a new Bluetooth protocol called Herald that will offer unparalleled app-level Bluetooth performance and contribute to better identification of potential close contacts. The update will improve our contact tracing capability, integrated with state and territory health authorities.

The Digital Transformation Agency ( « DTA » ) has been working with Apple and Google on incorporating the new protocol in the « COVIDSafe » App and performing extensive testing across all scenarios for both Android and iOS devices. The protocol provides for excellent performance of all encounter logging under all phone conditions and will continue to work on more than 96 per cent of Apple and Android phones.

The « DTA » has also been working with the Australian Cyber Security Centre to ensure the security of the new code meets the same stringent requirements as the previous versions of the « COVIDSafe » App.

Minister Hunt said now is not the time to be complacent when it comes to protecting yourself and your family against COVID-19 infection.

‘The Government is reinforcing the message not to be complacent in regards to the risks of spreading COVID-19 and how to stay safe, including having the App on your phone,’ Minister Hunt said.

‘The latest advertising campaign, which begins this week, is an important reminder that as we head into Christmas and restrictions are easing, people should maintain COVID-safe behaviours.’

Minister Robert said the code for the update is being made available now to the public via Github to enable the tech community an opportunity to provide feedback ahead of the release to the Apple App Store and Google Play Store.

‘Australia’s technology capability and contact tracing systems are world-leading and we will be the first country in the world to adopt the Herald Bluetooth protocol, which has been shown to significantly improve our capability through the « COVIDSafe » App,’ Minister Robert said.

‘We are continuing to welcome the input and feedback of the tech community and we are making the code available ahead of the release being available on the Apple App Store and Google Play Store. We are encouraging everyone interested to review the code, conduct their own testing and provide their feedback.

‘We are also making this code available to other countries so they too can benefit from Australia’s world first technology implementation to help improve their digital response to managing COVID-19.

‘Over 7.1 million Australians have downloaded and registered the « COVIDSafe » App and with states and territories opening up, now is a timely reminder to download or update the App to assist in keeping you and your family safe.’

When used as part of state and territory contact tracing efforts, the « COVIDSafe » App has proven to assist in identifying close contacts not picked up through manual tracing. New South Wales successfully accessed the « COVIDSafe » App to identify 80 close contacts, including 17 contacts that weren’t identified by manually contact tracing. In one instance, NSW’s access to the App revealed a previously unrecognised exposure date from a known venue (Mounties). This resulted in the identification of an additional 544 contacts, with two people from this group subsequently confirmed to have COVID-19.

In Victoria, it has been reported that 1,851 cases have said they have the App and are now using it as part of their contact tracing process. Victoria did stop using the « COVIDSafe » App at a point in time at the height of the second wave as it had not been integrated properly into their contact tracing process.

The « COVIDSafe » App continues to be an important part of Australia’s efforts to slow the spread of COVID-19. To protect you and your family, continue to practice good hygiene, practice social distancing and download and update the « COVIDSafe » App.
