With growing fears of a second coronavirus wave nationally, two states extended border restrictions and Australia’s most populous state-imposed limits on the number of people allowed in large pubs.

The changes come as scores of new cases were uncovered in Victoria, the country’s COVID-19 hotspot, despite a return to lockdown last week for nearly 5 million people in state capital Melbourne.

Active cases in the state rose to nearly 2,000 after another 270 infections were detected in the past 24 hours, authorities said, taking Australia’s total number of cases to about 10,000.

Australia’s death toll hit 110 on Tuesday after two people in their 80s died from the virus in Victoria.

“We haven’t turned the corner yet. I hope to see that this week, but there are no guarantees,” Brett Sutton, Victoria’s Chief Medical Officer told reporters in Melbourne.

Australia avoided the high COVID-19 casualty numbers of other nations with swift and strict measures, but a spike in community-transmitted cases in Victoria and a rise in new cases in New South Wales has worried other states.

South Australia canceled plans to reopen its border to New South Wales on July 20, while Queensland introduced a mandatory two-week quarantine for people who have visited two areas in Sydney’s western suburbs.

“Our primary responsibility in South Australia is to the health, safety and welfare of all South Australians,” Premier Steven Marshall told reporters in Adelaide.

Australia’s Northern Territory said it will decide on Wednesday whether to allow anyone from New South Wales to enter when its domestic borders reopen later this week.

New South Wales, which has seen several dozen cases linked to the outbreak in Victoria, said pubs will now be limited to no more than 300 people, responding to an outbreak centered at a large hotel in southwestern Sydney.

Authorities believe 600 people visited the Crossroads Hotel on July 3, when the outbreak is believed to have begun.

“Indoor activity, where people aren’t seated is a huge health risk. It increases the chance of transmission,” state Premier Gladys Berejiklian told reporters.
