Registering for your federation and AUSKF membership and paying dues can be done online.
Help with that process can be found at this membership registration help page section of this site.
If you are a dojo leader or a federation officer you can be granted access to the admin section of this site for additional features. Once given access, the admin link will be shown as the first one in the top navigation. There is a help section in the admin that you are encouraged to reference. Please feel free to provide feedback on that help section!
