NSW has recorded no new locally acquired cases of Covid for the fourth day in a row.
But health bosses are concerned the virus is still being transmitted unrecognised across Sydney as they scramble to find the city s missing link Covid-19 case.
NSW chief health officer Dr Kerry Chant said it was yet to be established how a man in his 50s from Sydney s east dubbed BBQ man become infected with the virus.
Apollo Global Management managing director Tom Pizzey travelled across Sydney last weekend while unknowingly infected with Covid, visiting four separate barbecue stores over the space of a few hours.
