Having been waiting for nearly a year for this.
Finally yesterday go the email "Thanks for registering! Clearing House Now Available". you can now complete the signup form. So I did that then today got another email "Welcome to Firstchoice employer super", you can ow register.
Clicked on the link to register. After entering the ABN & email address the process stops working. (Just sits there with a spinning status). This is why we needed this months ago to cater to the inevitable failure.
