People who visited a Blue Mountains public pool face an anxious wait to see if they have been exposed to COVID-19, as NSW records another six infections.
NSW Health notified the Blue Mountains City Council that a person who visited Katoomba Sports & Aquatic Centre on September 4 has tested positive, it was revealed on Saturday.
The person was a previously recorded case, and is not included in the six latest diagnoses.
One of the fresh cases is a returned overseas traveller in hotel quarantine, with the other five being locally acquired and linked to a known case or cluster.
Four are close contacts of previous cases associated with Concord Hospital, while the fifth is a household contact of a previously reported case linked to the St Paul's Catholic College Greystanes cluster.
One of the new cases is a also student of Blue Mountains Grammar School.
The school is being cleaned, and anyone identified as a close contact is being told to immediately get tested and isolate for 14 days.
NSW Health also issued alerts for the aquatic centre and a KFC store at Emerton.
Those who were at the centre between 11.30am and 1.30pm on September 4 must immediately get tested and isolate if they develop symptoms, NSW Health said.
The centre has been closed and will be deep cleaned.
"My immediate concern is for the community and council staff who may have been present at the facility on that day. This will be a nervous time," Blue Mountains City Council Mayor Mark Greenhill said on Facebook.
Anyone who attended KFC in Bunting Street at Emerton on September 7 between midday and 9:30pm must monitor for symptoms and get tested if any develop.
An alert has also been issued for two Sydney bus routes:
* 379 Bronte Beach - Bondi Junction station, 7 September 2020, 11.08am-11.24am
* 316 Avoca St Randwick - Bondi Junction station, 8 September 2020, 10.44am-11.05am.
Anyone who travelled on the routes must monitor for symptoms.
NSW Health is treating 86 cases including six in intensive care, four of whom are being ventilated.
In the state's south police charged two men at an Albury border checkpoint, with one of the pair allegedly travelling on a false permit.
A 39-year-old told police he was entering NSW for a medical appointment but his permit was found to be fraudulent.
A check of the vehicle allegedly found drugs and both the men were charged with possession, and will face court.
