Fears are growing that a two-week lockdown of Sydney will not be enough to contain the latest coronavirus outbreak plaguing the city. Epidemiologists say the outbreak, which began with international flight crew who passed the virus to a Sydney limousine driver, is far more concerning than the Northern Beaches cluster which required a three-week lockdown from December 19 to January 9. This is because it involves the more contagious Indian Delta variant of the disease and has affected about 260 venues across Sydney - rather than being largely contained in a peninsula over the Spit Bridge which could easily be closed off due to its separation from the rest of the city.
