Hello, it seems over 90 days and its over than normal processing time what has been experienced here. I will suggest you to contact CIC by sending them email or submitting a case specific inquiry. Do you have a file number from Sydney? You can also check the status of your application Online if you have file number.
Check Online case status with file number,

https://dmp-portal.cic.gc.ca/cicemail/intro-eng.aspxWhat I have experienced from other members, they are now days usually sending emails of results instead of mails but some applicants got mail contact too. So be sure to check you email if you submitted a email in forms, try to check your Junk email folder too. Good luck
