Hi VikingOz, Thank you for reaching out. Only one concession card can be registered to an account and the primary card holder needs to match the account details. To be able to link the concession card we would need to create a new account for you.
To assist you further with your enquiry please contact us. Our contact centre is available 24/7. You can find how to contact us via agl.com.au/contact-us.
Kind Regards,
Natalie
