The Australian state of Victoria has banned all global flights for 14 days over COVID-91 spike fears.
Residents in the suburbs must stay home unless travelling for work, school, healthcare, exercise or food for a period of four weeks.
From July 3, pubs, cafes, restaurants and clubs will not be restricted to a maximum number of people, provided there is 4 sq/m of space per person.
Tough border measures will also be introduced for anyone coming from Victoria, including mandatory hotel quarantine.
"We are all in this together and this is going to be deeply disruptive for those 10 postcodes. If we do not do this now, then I won't be locking down 10 postcodes, I will be locking down all postcodes".
The return to lockdown is a devastating setback for the home state of almost a quarter of Australia's 25 million people, widely seen to have taken one of the toughest enforcement approaches when the country first went into lockdown in March.
But Premier Annastacia Palaszczuk warned that strict measures could be reinstated if other states experience break-out coronavirus clusters such as the current outbreak in Victoria, which recorded another 64 cases overnight.
