Nando's at Stockland Wetherill Park was visited by a positive COVID-19 case on Sunday, and anyone who visited at the time is considered a close contact.
NSW Health advised yesterday that anyone who attended Nando's on Sunday, June 20 between 5pm and 7pm is considered a close contact of a positive case, and must immediately get tested and self-isolate for 14 days regardless of their test result.
Fairfield mayor Frank Carbone took to Facebook to share the news last night.
"I was hoping we had seen the end of Covid in our city," he wrote.
"However, after nine months without a case or any visit by a Covid case, tonight we have learned that the virus has escaped out of the inner city areas and that Nando's at Wetherill Park has been visited by someone who has tested positive to Covid.
"Council has maintained the drive-through testing at Fairfield Showground and anyone can just drive through and get tested, safely, quickly and for free.
"The restaurant has been deep-cleaned and made safe. I feel for Nando's and their staff who have had this through no fault of their own.
"We need to make sure we continue to support any local businesses that are impacted, to support them and our local jobs."
A positive case also visited Willowdale, on the outskirts of Liverpool.
Anyone who visited Coles Willowdale Neighbourhood Centre (Denham Court) on Monday, June 21 between 4.45pm and 5.05pm is considered a casual contact and must get tested immediately and self-isolate until a negative test result is received. They are asked to monitor their symptoms and get tested again if COVID-19 symptoms develop.
