MELBOURNE, AUSTRALIA - MAY 13: People walk and ride along the beach at Brighton on May 13, 2020 in Melbourne, Australia. COVID-19 restrictions have eased slightly for Victorians in response to Australia's declining coronavirus (COVID-19) infection rate. From today, people in Victoria will be allowed to visit friends and family. A maximum gathering of up to ten outdoors is allowed, or up to five visitors inside a home.

(Bloomberg) -- Australia’s second-most populous state has tightened coronavirus controls as a spike in cases triggers fears the nation could be hit by a second wave of infections.

Victoria extended a state of emergency by four weeks to July 20, halved the number of visitors allowed in homes to 5 and delayed a planned increase in the size of gatherings in cafes, restaurants and pubs.

The weekend announcement, and a jump in cases in countries including the U.S., Israel and South Korea, heightened market concerns about the difficulty of reviving economic growth while controlling the spread of Covid-19. The Australian dollar declined against most of its Group-of-10 peers on Monday, falling as much as 0.4%.

Australia has managed to limit the total number of coronavirus cases to 7,460 by closing international and state borders, quarantining returning residents, social distancing measures and a widespread testing and tracing regime. But concerns are growing about community transmission in Victoria, responsible for 116 new cases in the past week -- 83% of the national total. Of those, 87 were largely associated with community transmission.

Health authorities are warning people to avoid traveling to six areas in the state capital, Melbourne. A professional Australian Football League match scheduled to be played in the city on Sunday was postponed after a player contracted the virus.

The spike in cases may cause states and territories such as Queensland, Western Australia and Tasmania to keep their borders closed beyond July, despite pressure from Prime Minister Scott Morrison to allow inter-state travel to boost tourism and buoy the shattered economy.

Australia’s Chief Medical Officer Brendan Murphy on Monday said he was concerned by the “fairly rapid rise” of infections over a few days in Victoria, which appeared to be caused by family gatherings. In some instances, people who had tested positive or come into contact with an infected person had failed to self-quarantine.

“Complacency is dangerous,” Murphy told the Australian Broadcasting Corp.

There was no sign the Black Lives Matter rally in Melbourne earlier this month had caused a spike, he said. Officials don’t believe the three protesters who have tested positive were infected at the rally, or transmitted it there. However, the mass protests may have encouraged other people to flout social distancing rules and gather in larger numbers, he said.

If lockdown measures are re-imposed more widely, it could further damage the economy and erode business confidence and consumer sentiment, said Nathan Cloutman, a senior industry analyst at IBISWorld. “Businesses are now less likely to re-stock supplies and re-hire employees when social distancing is removed, out of fear that restrictions will be re-imposed before they can generate revenue to cover those costs.”
