At least three new ‘mystery cases’ of the novel coronavirus have been discovered in Greater Sydney’s northern beaches, which the epidemiologist warned could spread faster ‘like fire’. The sources of locally transmitted infections have not been known yet. In a state press conference, NSW Premier Gladys Berejiklian said that the three new cases that have been identified had no immediate link with the northern beach cluster. She imposed the state on “high alert” and urged the residents to get tested for even mildest of symptoms as they approach New Year’s Eve. 

Of the total cases linked to the Avalon cluster, one reportedly travelled resided in Wollongong on the NSW south coast and had travelled to Sydney. The others, meanwhile, resided in the inner west and north of Sydney. The mysterious COVID-19 cases were diagnosed from the total 16,329 tests conducted in the 24 hours by 8 pm. In another worrying scenario, a Sydney airport van driver who commuted the international flight crews to-and-from the airport had tested positive for COVID, prompting the health authorities to conduct mass scale tracing.
