My 186 DE was just approved on 24th Oct. It took less than 6 months from the day we lodged the application.
Employer nomination and visa application lodged : 3 May 19
More Information request : 2-3 weeks ago
Visa approval : 24 Oct 19
Occupation : Software Engineer
I submitted all the necessary documents in advance and maybe this sped up the process. My colleague had his visa 186 TRT approved in just 3 months.
Good luck to those who are still waiting for the result. Cheers
