It's a challenge that's testing the skills of NSW's team of contact tracers — how to track down nine passengers who didn't book or pay for taxis with their credit card and who may have been exposed to COVID-19.
That's the task ahead of health authorities after a taxi driver worked while infectious over eight days in Sydney's west and south west earlier this month.
Anyone who caught a Silver Service sedan taxi on September 7 to 10 and September 14 to 18 in Moorebank, Bankstown, Chipping Norton, Liverpool, Lidcombe, Warwick Farm and Milperra, could be at risk — especially if they didn't book or give their details.
All nine mystery passengers are considered close contacts, so the race is on to identify them so they can immediately self-isolate and get tested for the virus.
