SYDNEY, June 28 (Reuters) - Australia's COVID-19 response committee is due to hold an emergency meeting on Monday as outbreaks of the highly contagious Delta variant across the country prompted a lockdown in Sydney and renewed restrictions elsewhere.
Around 18 million Australians, or around 70% of the population, are now under some form of lockdown or COVID-related restrictions as officials grapple with COVID-19 flare-ups in almost every state or territory.
