UPDATE Wednesday 3pm: Anyone who visited Lawson oval on Sunday, September 13 between 10.30am and 12.45pm is being urged to monitor for COVID-19 systems.
The warning comes after NSW Health confirmed two cases linked to Springwood Sports Club on September 12 also visited Lawson oval the following day during a soccer match.
NSW Health said anyone who attended the oval in that time period is considered a casual contact and "must monitor for symptoms and get tested immediately if they develop".
"After testing, they must remain in isolation until a negative test result is received."
Hazelbrook Hawks Football Club posted on its Facebook page on Wednesday afternoon [September 16] that the two people who have tested positive were present at Lawson oval during a Nepean FA fixture match.
"The club is in regular contact with the Nepean Blue Mountains Public Health Unit who have advised that football activities can continue as normal. One team will have fixtures affected and have been informed, but all other scheduled fixtures and football activities including training and today's Skills Squad can proceed," the club posted.
"As always, members are asked to monitor for symptoms and follow the Football NSW COVID-Safe guidelines sent out previously and which can be found on the club's, Nepean FA and Football NSW websites."
Anyone who attended Springwood Sports Club on September 12 from 1-2 pm time is also considered a casual contact and must monitor for symptoms and get tested immediately if they develop.
Wednesday 9am: Springwood Sports Club has been linked to COVID-19 through a weekend visitor.
NSW Health contacted the club yesterday (September 15) to notify it that a person who visited the club on Saturday, September 12, between the hours of 1pm and 2pm had tested positive.
This made the club as "casual contact" venue.
NSW Health defines a 'casual contact' as: "Someone who has been near a confirmed case of COVID-19 while they were infectious but is considered at lower risk than a close contact. They should still be vigilant and watch for symptoms but casual contacts are not required to self-isolate in their homes unless they develop symptoms."
Paul Barnett, CEO of the Mingara Leisure Group which owns the club, said in a statement: "With this advice and under the category of 'casual contact', NSW Health has advised no further action is required from Springwood Sports Club and the club can remain open."
He said the club is following guidelines and has a COVID-19 plan. It has COVID-19 marshals in place and the club is cleaned multiple times a day and overnight each night.
"The school is now closed while further tracing and cleaning is undertaken," NSW Health posted on Facebook yesterday morning.
