What do I do if my Child concession expires? In order to receive child fares, you will need to use a Green Snapper card. These will always receive a child concession and do not expire. You can purchase one from our web store, or a SnapperĀ retailer. Historically, child concessions could be added onto Red Snapper cards. (this includes some Student ID Snapper cards, before they were printed on Green Snappers). For existing child concessions on Red Snappers, we are happy to extend these if they expire while the cardholder is still eligible for a child concession. Reach out to us to enquire about this. TIP: As long as the card is registered, a concession expiry reminder email will be sent to the registered email address in the month before the expiry is due to occur.
