Recreational competitors wanting to pay their 2017 Registration so that they can enter 2017 Competitions may do so by logging into their P5000 account. There will be a button (upper right for PC) that says 2017 Payment, this will take you to the PayPal page.
Amateur competitors need to renew via the payment portal on the main DSA site at www.dancesport.org.au or contact their State Registrar.
