Zero cases were reported in the 24 hours between 20:00 on Friday and 20:00 on Saturday – the first time this has happened since 9 June.
According to the BBC, the state of Victoria – epicentre of Australia’s second wave – recorded zero cases for the second day in a row after a 112-day lockdown.
“Thank you to all of our amazing health & public health workers & above all else the Australian people,” Health Minister Greg Hunt said on his Twitter account.
Australia has recorded some 27,500 infections and 900 deaths to Covid-19 since the pandemic started – far fewer than many nations.
Health officials say more restrictions may be eased in the coming days.
