Shoppers wear masks as they walk around a shopping precinct in Sydney, Australia, Sunday, January 3, 2021. Masks have been made mandatory in shopping centers, on public transport, in entertainment venues such as a cinema, and fines will come into effect on Monday as the state government responds to the COVID-19 outbreak on Sydney's northern beaches, which is suspected to have also caused new cases in neighboring Victoria state.
