Returning members from previous years or new members all need to register with the association online.
Go to https://myaccount.rugby.com.au/choose-registration
and select your own account to register. Enter "Victorian Referees" when searching for your club, and answer the questions. Typically if nothing has changed since last time you registered, keep clicking next until you get to the end.
