Six million Australians have downloaded the COVIDSafe app less than a month after being launched to help health authorities across the nation trace coronavirus infections.
Federal Health Minister Greg Hunt said the app is playing a significant role in Australia's response to the pandemic and several countries have expressed interest in learning from its positive impacts.
"Australia continues to be a world leader in testing, tracing, and containing the coronavirus and I would encourage all Australians to contribute to that effort and download the COVIDSafe app today," Mr Hunt said in a statement on Sunday.
Only state and territory health officials have access to contact information from the app which is triggered when people come in close contact with someone who has the virus - that is 1.5 metres or less for a duration of 15 minutes or more.
Government Services Minister Stuart Robert said the take up of the COVIDSafe app was downloaded faster than any other Australian government app and has consistently remained in the top three apps in Australian app stores.
"Millions of Australians are doing their bit as part of our health response," he said.
