A student who attends a school more than an hour's drive from Sydney's CBD has tested positive for Covid-19 after contracting the virus on holiday.
The infected student attends the Hawkesbury High School in Freemans Reach, 65km north-west of Sydney, and contracted coronavirus during school holidays.
The school principal Igor Maric, confirmed in a statement that a positive case had been identified in the community and said the student was currently in isolation.

'NSW Health have conducted contact tracing and all close contacts have been identified and tested', the statement read.
'The student in question will remain in isolation and he will not be attending school until he gets cleared by NSW Health.'
The principal said while the school remains safe, parents should remain extra vigilant and get their children tested if they have even the mildest symptoms.
Mr Maric said that while the school remained open for students whose parents need it, he urged all parents to keep their children at home.
