Thank you.Hi Cloud and all others, my brief timeline is as follows:
Visa Applied: 30th Dec 2013
Team 13 Contact: 3rd May 2014
ESC Started: 14th May 2014
Grant: 2nd July 2015
All I know is my last contact with Immigration was on 12/06/2015 and that that time my case was still ongoing. I called them yesterday and the officer took a long time looking at my case telling me that your file is for review in the coming days. So I am assuming somewhere between 12/06/2015 and today ESC was cleared.
I would say anyone who's ESC went before or around the same time as me give DIBP as nudge to see if there's any update.
All the best and best of luck, I'll definitely stick around.
