Hi and thanks for this useful thread. I'd like to add my details to the timeline so that we can have more statistics.
186 visa transition stream from 457 (me and my de facto partner)
Nomination and visa app 17/08/14 (all documents provided)
No news up to now. Immi account says "in progress, last update 17 Aug 2014". I called immigration but they replied with "standard" web site processing times.
Thanks!
