A Southport boarding school closed for three days this month after reports of a gastro outbreak has sent hundreds of students and many teachers home from school.

Over 400 students were affected when the school announced it would close on March 23rd, just three days before the end of first term.

While it is understood that the number of affected students has decreased since it was first discovered five weeks ago, the school will still ended its term 3 days early to allow anti-virus personnel to sanitize the school.
