Greater Sydney residents will be required to wear masks in certain indoor settings from midnight on Saturday night.
NSW Premier Gladys Berejiklian announced the measure on Saturday morning along with several other coronavirus restrictions, as the state recorded seven new locally-acquired COVID-19 cases.
People in Greater Sydney will have to wear masks in supermarkets, shopping centres, cinemas and indoor entertainment venues, on public transport, in beauty salons and hairdressers, places of worship and gaming areas.
