"It is disappointing that we are not able to maintain our normal school format for now, but we are confident, given our past experience with home learning, that our students can continue to learn positively and constructively.
"It is important for us to keep a sense of perspective at this time to navigate the ever changing situation with care, planning, flexibility and effective communication."
The notice indicates that Year 9 and 10 camp would continue as normal, school sports training and games could still go ahead.
Students that aren't able to do learning from home are able to register to attend supervised learning at the school's library.
"Our duty of care for our students, staff, and our school community is our highest priority," Shepherd wrote.
A school spokesperson said affected students were absent for various reasons including contracting Covid and self-isolating as household contacts or other unrelated reasons.
While the numbers of those absent hadn't increased in recent months, the school was moving to online learning for the coming week due to not having enough staff to adequately cover classes.
Students would be able to return from Thursday, May 19.
