TORONTO court house will be thoroughly cleaned after a confirmed COVID-19 case in a person who attended last Monday, NSW Health confirmed on Sunday.
NSW added 29 new coronavirus cases in the two days to 8pm Saturday, including the Lake Macquarie case.
NSW Chief Medical Officer Dr Kerry Chant said the patient attended drug court on July 27. She urged anyone else who attended the Cary Street premises between 7am and 2pm on the same day to watch for symptoms.
If symptoms emerge, they are urged to self-isolate and seek testing for the virus.
NSW Premier Gladys Berejiklian urged people to wear masks while on public transport and buying groceries, staff dealing with customers, during religious worship and in areas with high community transmission from Monday.
"I want to stress it is not compulsory but it is a strong recommendation from Health," Ms Berejiklian said.
The Hunter recorded no new cases in Friday and Saturday's numbers.
The Department of Communities and Justice said it had received confirmation "that a member of the court at Toronto has tested positive".
"The person last attended the Toronto Court House on Monday, 27 July, and the positive result was received on Saturday (1 August) evening. As a precaution, cleaning of the courthouse will take place today (Sunday). The person was likely infected at the Apollo restaurant in Potts Point," the department said in a statement.
"All close contacts have been identified and are being contacted this morning by NSW Health. As a precaution, anyone who was in attendance at the Toronto Court House between 7am and 2pm on Monday, 27 July should watch for any symptoms.
"Should even mild symptoms develop, they must self-isolate and seek urgent testing for COVID-19."
