Nine new cases of COVID have been recorded in NSW including one where the source is unknown.
Of the nine cases recorded in the 24 hours to 8pm on Saturday, four are returned travellers in hotel quarantine, four are locally acquired and linked to known cases and one is locally acquired and under investigation.
NSW Health on Sunday said two of the new cases are household contacts linked to the Eastern Suburbs Legion Club cluster and the other two are linked to St Paul's Catholic College Greystanes.
All four cases have been in self-isolation while infectious.
NSW Health also advised an infected person visited KFC in Concord on September 6 with anyone who was at the restaurant between 1pm and 1.20pm that day considered a casual contact.
They have been advised to monitor for symptoms.
NSW Health acting director Dr Christine Selvey urged people to immediately get tested if they feel unwell and to maintain social distancing.
"COVID-19 continues to spread in the community and we must all continue to help stop the spread of this disease," Dr Selvey said in a video update on Sunday.
NSW Health is treating 83 COVID-19 cases including six in intensive care, three of whom are being ventilated.
