The Australian state of Victoria will punish people who breach their self-isolation orders with an on-the-spot fine of about $5000.
It comes as the state recorded 11 more deaths from COVID-19 and the state's case numbers have risen by more than 400.
On Tuesday Premier Daniel Andrews confirmed 439 new infections out of 21,000 tests. It's an increase of ten from the previous day.
One of the deaths was a woman over 100. The other victims were a man in his 70s, three women and one man in their 80s and another three women and two men in their 90s.
Andrews said the level of compliance from those supposed to be self-isolating was "completely unacceptable" and warned infringers would be hit by harsh fines.
"I can confirm that the ADF [Australian Defence Force], together with important authorised officers from the Department of Health and Human Services have conducted more than 3000 door-knocks of people who should be isolating at home. More than 800 of those homes, the person who should have been isolating could not be found," he said.
"That is completely unacceptable.
"From now, there will be no exercise if you supposed to be isolating at home. You will need to stay in your home or on your property. Fresh air at the front door. Fresh air in your front yard or back yard or opening a window.
"I apologise to those who were doing the right thing but we have simply no choice but to move to that setting."
