Before booking your tickets, make sure the business is an Affiliate of WA Companion Card. You can find a list of Affiliates here.
Each Affiliate will have a different way of booking tickets to an event or activity. This could include booking online, over the phone or in person. Contact the Affiliate directly to find out the best way to use your Companion Card when booking a ticket.
When you attend your event or activity, you should take your Companion Card with you, just in case you need to present it at any time.
