Victoria faces new measures after virus cases spike, with a curfew being composed in Melbourne.

South Africa has reported more than half a million coronavirus cases to date, its health minister has said, as a resurgence of Covid-19 sweeps the country.
Zwelini Mkhize announced 10,107 new cases on Saturday, bringing the tally to 503,290, along with 8,153 deaths.
South Africa is the hardest-hit country on the continent and accounts for half of all reported infections in Africa.
The country had imposed a strict lockdown in April and May that slowed the spread of the coronavirus.
But health authorities say the rate of infection is increasing rapidly, with cases currently concentrated around the capital, Pretoria.
Infections are not expected to peak for another month.
