It is a requirement of the P&C Federation that all members who wish to vote need to be financial members of the P&C. To become a voting member of the P&C you will need to attend a P&C meeting and pay a fee of annual $2. You can join the P&C at any time during the year, however all memberships are due for renewal in the beginning of each year.
For a reference please see P&C Federation website.
You don’t need to be a member to attend meetings, volunteer or be part of the parent school community.
