Perth College principal Helen Aguiar told Radio 6PR the incident occurred over the Easter school holidays and was reported to police on Wednesday.
“I had a student over the holidays who obviously accepted a friend request from Instagram – which I would never send to students – and started a conversation thinking it was me,” she said.
“[The messages] started quite general, ‘Hi, how are you going’, ‘how are your holidays’, and the last question was, ‘Where are you now?’ and that’s when the student thought, ‘this is not the principal’ and … reported it to her teacher on the first day of school this term.”
Ms Aguiar said her first reaction after seeing screenshots of the conversation was to ensure students at the school were safe.
“That was just chilling when I saw it,” she said.
“But on the flipside, the student did everything that we have taught students to do.”
Students and parents were informed of the social media breach immediately.
“The reality is there’s so much of this going on that the police said it’s on their list, it’s on their radar, but it’s not the highest priority because obviously there’s more serious incidences going on around WA,” Ms Aguiar said.
