Mine VO is Sydney too. (AOR 14th May - CEC)
Only Medical passed in June and no updates since then.
I raised webform to ask them the status on 14th May. I called agent today and requested her to send a note to VO for expediting the file. She told me that they also just send the webform kind of note which I have already sent. However, it is upto case officer when they will take it.
Also, once the 6 months are passed then there is no prediction when the process will complete.
@legalfalcon : Is it really true that Sydney office takes around 8 months for processing? What is your experience on it?
