Click on the course name for course information. 

If you have not registered for an Australian Sailing course before, then you will need to get an Australian Sailing number first.  When you click on 'Register' the following text appears low on the left side of the linked page:

Don't have an Australian Sailing Number?

Begin your registration here

Start your registration with that "Begin..." link.

Otherwise, use the Australian Sailing Number finder to get going unless you happen to know your Australian Sailing Number (who does?)

Don't know your Australian Sailing Number?

Find your Australian Sailing Number online

Then copy and paste your number back into the registration form.

Click on 'Register' and it will make sense....
