The prospect of an extended lockdown in Sydney loomed on Monday as Australian health officials reported yet another record daily rise in Covid cases for the year, fuelled by the highly infectious Delta variant.
New South Wales state reported 112 new locally transmitted Covid cases, almost all in Sydney, despite the country’s biggest city entering its third week of lockdown. Case numbers have been at record levels for at least three days.
There was, however, a glimmer of light as the number of newly-infected people who were out in the community while infectious dropped to 34 from 45 on Sunday.
State Premier Gladys Berejiklian said the progress of that figure in coming days would determine whether Sydney’s lockdown, due to end on Friday, would be extended.
"That’s the number we need to get as close to zero as possible," Ms Berejiklian said during her daily televised briefing. "It is really up to us. The health expert advice will be based on what those numbers look like. I can’t be clearer than that."
Ms Berejiklian said most of Monday’s cases were family members or close friends of already infected people, and pleaded with residents to comply with lockdown rules, which were tightened over the weekend.

Total infections in the outbreak are nearing 700, less than a month since the first was detected in mid-June. Sixty-three people are in hospital, with 18 in intensive care, officials said, while a woman in her 90s became the country’s first Covid-19 fatality this year.
Lockdown measures for Sydney’s five million residents, including school closures and stay-at-home orders, have stoked concerns of a slowdown in the economy, which had returned to pre-pandemic levels in the first quarter.
Australia has previously successfully suppressed Covid-19 flare-ups through snap lockdowns, speedy contact tracing and tough social distancing rules. With a total of around 31,200 cases and 911 deaths since the pandemic began, the country has fared better than many other developed economies.
The Sydney outbreak has put Australia’s sluggish vaccine rollout under scrutiny. Just 11% of Australia’s adult population of just over 20.5 million have been fully vaccinated.
Critics have pointed to confusing public advice as well as vaccine shortages.
Federal health guidance recommends the locally-produced AstraZeneca vaccine be restricted to people aged over 60 because of blood clot concerns, while the imported Pfizer vaccine is currently limited to people between 40 and 60.
However, New South Wales authorities said vaccination centres and pharmacies would now be authorised to give the AstraZeneca vaccine to anyone over 40. NSW officials have also recommended shortening the interval to six weeks between AstraZeneca vaccination doses from the recommended 12 weeks.
