Australia's Victoria state on Friday reported a record daily increase in COVID-19 cases while neighboring New South Wales said it was banning dancing, singing and mingling at weddings as authorities struggle to contain a new wave of infections.

Victoria, which has forced nearly 5 million people in the country's second most populous state into a partial lockdown for more than a week, said it has found 428 new COVID-19 cases in the last 24 hours.

Such is the size of the Victoria outbreak, Australia posted its biggest one-day rise in new COVID-19 infections since late March even with several states still to report.
