Several coronavirus clusters have emerged in Australia’s two most populous states, officials have said, prompting the biggest, New South Wales (NSW), to delay easing some restrictions.

The NSW Premier Gladys Berejiklian said she was concerned the state was on the cusp of another major community transmission after 11 new cases were locally acquired and a cluster appeared in the southwest Sydney suburb of Lakemba.

She said the easing of some social restrictions involving restaurants and weddings would now be put on hold.
