While students and staff self isolated, the school was closed for the day for cleaning and contact tracing.
The closure came the same day that the State Government announced a staggered return to face-to-face learning in October.
The Department of Education has developed a plan for a staggered return to school in a Covid-safe way from October 25 while stay at home orders are still in place.
Premier Gladys Berejiklian says the NSW Government is prioritising the safety and education of students through a sensible and managed return to school.
