Hundreds of potentially Covid-infected Sydney residents were left to wander the streets for four days after an embarrassing contact tracing error,. NSW Health issued an alert for the Crossroads Hotel in Casula, southwest Sydney - infamous for being the epicentre of an outbreak with 65 infections in just ten days last year. Customers who were there on Wednesday evening were told to get tested immediately and isolate for 14 days regardless of their result. However, the alert was actually meant for the Crossways Hotel on Liverpool Road in Strathfield South - 25km away - at 7pm to 10.30pm on the same day.
