Long time lurker, but created an account today as I wanted to share my good news with someone. I think I may have broken the record... I lodged my 457 application on 21/12/16, uploaded my evidence on 22/12/16 (because the immi webpage wasn't working for me on the 21st), and got my visa granted on 22/12/16!! To be fair, I am from and am living in low-risk countries, and I got a job offer that starts on 16/1/17. And I've got no dependents. I would like to think is still possible that they are still processing today applications today, so good luck and happy holidays!
