Australia's second most populous state Victoria has extended its state of emergency for four more weeks to 19 July, as it battles a spike in coronavirus infections with a pick-up in community transmission.

The move came a day after the state announced it would reimpose restrictions capping visitors to households to five people and outdoor gatherings to ten, starting tomorrow.

The limits had been relaxed on 1 June to allow up to 20 people in households and public gatherings.

Victoria reported 19 new infections today, the fifth day of double digit-rises. The state has now had 1,836 total confirmed cases, or a quarter of the cases in Australia, since the Covid-19 pandemic erupted.

The tally in Victoria includes former Tyrone GAA player Conor McKenna, who now plays in the Australian Football League. He is the first player in the league to test positive for the virus. His teammates and coaching staff have been told to isolate.

The surge in Victoria has alarmed other states, which have had only a few, if any, new cases for several weeks.

Western Australia, which shut its borders in April, said it would weigh Victoria's situation in determining when to reopen its borders.

Victorian state health minister Jenny Mikakos said 210 of the state's cases are believed tied to community transmission, partly blaming families who have had parties, lunches and dinners attended by people with mild symptoms since restrictions were eased on 1 June.

"We obviously have been concerned by the increasing numbers that we have seen in recent days. It is still a very serious situation," Ms Mikakos said.

State police said they planned to step up enforcement efforts, especially in suburbs where there have been breakouts and patrolling ski resorts and camper-van parks during the upcoming school holidays.
