About Us
Registration
Registration for the upcoming season is open January 15th- March 1st. Once a division is full a waitlist option will open up - notification of being accepted from the waitlist will occur mid-March. All refunds will be subject to administration fee and will not be accepted after March 15th. We will be offering payment by email transfer.
If you are registering siblings in the same division, you MUST enter the siblings full name on both registration forms in order for siblings to be placed on the same team. Where this was not completed on registration and the teams have been created, the league will attempt to make swaps however this will not always be possible and there will be an additional fee charged where new uniforms have to be ordered. Children registered in the wrong division (based on year of birth) will be moved to the appropriate division when the teams are created. Friend requests are not guaranteed and will only be considered when noted on the registration form.
Click on the button below to register. Please follow all directions on the registration form to avoid errors.
Registration is considered complete once payment is received.
