Australian states have tightened restrictions on movement as authorities struggle to contain a fresh outbreak of Covid-19 in the country’s southeast that has pushed the national tally of cases beyond 10,000.

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 five million people in state capital Melbourne. “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, according to Reuters.
