Australia's second-largest city has begun a second lockdown in response to a spike in new coronavirus infections.
Five million Melbourne residents will be barred from leaving home for six weeks, except for essential reasons.
Borders between Victoria, of which Melbourne is the capital, and neighboring states closed on Tuesday.
Prime Minister Scott Morrison also said he was proposing measures to slow the return of Australians from overseas.
Victoria State Premier Daniel Andrews announced the Melbourne lockdown after the state saw 191 new infections, its highest daily number since the pandemic began.
Wednesday's figure was down to 134, but still much higher than numbers in the rest of the country.
Australia has recorded almost 9,000 cases and 106 deaths from the coronavirus.
