There was one new case of COVID-19 reported in the northern rivers to 8pm on Wednesday.
The case was reported in the Tweed LGA, and is linked to a known case in the ACT which is where the infection was acquired, said Lynne Weir, Acting Chief Executive of the Northern NSW Local Health District.
The case has been in isolation throughout their time in Northern NSW, she said.
"A small number of close contacts have been contacted directly by NSW Health, but there are no identified public venues of concern associated with this case," Ms Weir said.
Fragments of the COVID-19 virus have been detected in samples taken from the Grafton sewage treatment plant on 20 September. This detection is concerning given there are no known cases in the area.
Further sewage surveillance has detected fragments of the virus in samples taken from the Wardell sewage treatment plant on 21 September, the third detection in that area in the past 10 days.
"We urge anyone in the Grafton and Wardell areas who has even mild cold-like symptoms, to get tested and isolate until a negative result is received," Ms Weir said.
Health authorities are investigating a number of new venues of concern associated with a confirmed case of COVID-19 who was in the Ballina LGA.
Surveillance testing is continuing today at Cabbage Tree Island. All members of the community had been being asked to come forward for testing after a person who is now a confirmed case of COVID-19 passed through the area last week.
