SYDNEY (Reuters) - Australia's New South Wales (NSW) reverted on Friday to making the wearing of masks mandatory on public transport in Sydney, as a cluster of the highly-infectious coronavirus Delta variant expanded to a fourth person.

Authorities said all planned outdoor events with good COVID-19 safety plans can proceed in the country's largest city.
