Hello, long time silent observer here. This forum posts have been a great help to me so far, and I would like to share my timeline:
187 DE, onshore, LR, 1 person
State: QLD
Processing centre: WA PESE
Visa application done by myself, nomination and RCB done through MA by employer.
Occupation: Dentist
RCB approval: 24 Mar 2017
Visa and nomination submitted: 1 Apr 2017
Nomination approved: 11 Aug 2017
Additional documents (AFP clearance) requested: 11 Aug 2017
Visa granted: 28 Sep 2017
Called up immigration this noon, and was advised that generally when you are requested for additional documents, your case will be reviewed in 30 days, but due to high volume of applications, this is being delayed. Yet got visa approved in less than 3 hours.
Hope this helps.
