It comes as Murray River Council recorded eight new COVID-19 cases in the 24 hours to 8pm on Sunday night.
The LGA recorded three new cases each on Saturday and Sunday, and one on Friday, October 29.
Principal Scott McKenzie confirmed the closure on the school’s Facebook page.
“I would like to confirm with you that a member of our school community has tested positive for COVID-19,” Mr McKenzie said.
“Our school will be non-operational effective immediately for the on-site attendance of students and staff to allow time for contact tracing and cleaning.
“All staff and students are asked to self-isolate until you receive further advice.
“There is no requirement to get tested at this time.
“During this time, learning-from-home resources will be available from the learning-from-home hub.”
A NSW Education spokesperson said most schools were normally closed for 24 hours only for contact tracing and cleaning.
“NSW Health has requested anyone who has been unwell or if you develop any symptoms, such as a fever, cough, sore throat, shortness of breath, runny nose, loss of smell/taste, muscle/joint pains, diarrhoea, nausea/vomiting or extreme tiredness to be tested at one of the COVID-19 testing clinics,” the spokesperson said.
