A Catholic school in Warrawong is one of a number of new Illawarra sites exposed to the COVID-19 virus.
Two students at St Francis of Assisi Catholic Parish Primary School have tested positive for COVID-19.
This led to the school being closed on Friday to allow health officials work through a contact tracing and cleaning response strategy.
The school is receiving support from the Catholic Education Office's COVID-19 Incident Response Team.
NSW Public Health Unit representatives are also providing specialist advice and the school is working closely with them to undertake detailed contact tracing.
Those identified as close contacts will be contacted, with the school to undergo the necessary deep clean in accordance with health requirements.
"Once this is complete and the Ministry of Health provides its approval, the school will be able to reopen for supervision for those students who are unable to learn from home.
"Catholic Education Diocese of Wollongong (CEDOW) continues to receive advice from NSW Health, Catholic Schools NSW, and other relevant agencies to ensure best practice," a CEDOW spokesperson said.
