Some great news from me!
186 DE granted on 4th May. Less than a month from application. Below is the timeline and other details:
Application date: 16th April 2021
S56 request for health check: 20th April 2021
Health check completed on 27th April 2021 and migration agent confirmed results were uploaded by the clinic on 29th April 2021.
DHA called my employer on 4th May morning to confirm employment and few other details. Visa granted by afternoon of the same day. Very, very quick.
Occupation: Software Engineer (261313) which is on PMSOL
Location: Offshore (yes, that's not a typo!). Working remotely from home at the moment.
I was concerned that offshore applicants weren't being looked at but I believe for PMSOL occupations it doesn't really matter. Happy to answer any questions that may assist other people.
(Please do not ask me about my employer's details, however)
