Kelston Girls' College briefly went into lockdown on Tuesday afternoon after a window was smashed following a fight.
The school posted on social media asking parents to refrain from coming in, as it "may cause disruption to the management of the incident" and put people at risk.
An update on the school's website later said the issue was resolved, and it was undertaking a "controlled release" of all students.
Police confirmed a woman was being spoken to following the incident.
"Earlier this afternoon a fight occurred between two students," a spokesperson said. "A woman known to one of them came onto school grounds and smashed a window".
The school called the police and the suspect was located.
"No one has been injured - the school initiated a short precautionary lockdown, which has since lifted," police said.
The investigation was ongoing, but police were not seeking anyone else.
