Yes, possibly. You can vote in any school council for which you are an eligible elector.

If you are the parent/guardian of students attending more than one school, and/or live in an area with overlapping attendance areas, you may be able to vote in more than one school council election.

You cannot however vote in the same election more than once; i.e. you cannot vote in the same school council election based on both residency and attendance or having more than one child at the same school.
