When volunteering to help out at the school you need to have a WWVP card. Please ensure that your card is current and that the office has a copy on file. 

If you don't have one please follow the link. You can complete the paperwork online in 15 minutes and take the documentation to your closest Access Canberra. There is no fee for volunteers.
