The students and staff were forced to isolate following a visit to Camp Yarramundi, near Richmond, last week, after the Blue Mountains was included in Saturday's extension of stay-at-home orders initially imposed on Sydney two days prior.

While there was no restrictions in place during the excursion last Tuesday and Wednesday the extension of the order was imposed retroactively from June 21, the day before, requiring the group to isolate on return to Orange as a result.

"We're following all the guidelines in place. I've been in contact with the year eight coordinator and as far as I know no one involved has displayed symptoms," Mr Meers said.

"Of course, we are encouraging everyone to follow all the NSW Health guidelines and information around the restrictions as well particularly if they do become symptomatic."

Mr Meers contacted parents and caregivers via email on Sunday afternoon and although the school is closed during the holidays, until July 12, he said he will continue to provide updates on the situation when, or if they arise.

He explained there was some consideration given to postponing the excursion, however with no restrictions at the time and extra precautions being taken, the decision was made to 'go ahead as planned'.

He offered reassurance the group had 'minimal contact' with external parties during the excursion.

"There were no restrictions in place at the time, the location in north Richmond was quite a long way away from the hot spots identified and we were making efforts to ensure minimal contact," Mr Meers said.

"The group was on hired coaches and not public transport and they only made one stop on the way, at a McDonald's. However the kids didn't get off the coach, the food was ordered and brought back to them.

"They were at the camp by themselves and there was no contact with other schools or groups. They arrived, completed their activities and returned to Orange."

As he did in his email on Sunday, Mr Meers again apologised for the 'frustrating' situation, particularly considering the isolation period aligns almost completely with the school holidays.

However, he said it is a necessary move, praising the support thus far from parents as the school follows the government's stance and restrictions in its continued bid to minimise the risk of infections spreading.

"It is frustrating," he said.

"I'm sure there was a lot of families planning to go away or travel to areas outside of the red zones during the holidays, which they won't be able to do now.

"No doubt the students and their parents, and the staff members too, would have been very much looking forward to their holidays too so I'm sure there's a lot of disappointment.

"We share in that frustration and disappointment, and we are very sorry for it but we are very conscious of the rules and playing our role to help fight the coronavirus."

Western NSW Local Health District said there had been no confirmed cases of COVID-19 in Orange or the region when contacted on Monday.
