Now the waiting begins, my friend! And trust me, it is rather upsetting often times... the fact that you don't know whether they started to evaluate your application of not... thinking that they might have sent the application back (even though you know you checked everything 4 times)... it can be quite overwhelming... be patient, is a good piece of advice for you right now

I started trying to link my paper application to my online account after 60 days since my application was received. Finally, after 81 days I successfully got it linked. I guess the case processing centre in Sydney is catching up a good speed now, so it could take less time for you to receive some news about your application.
Best of luck for you!
