My personal timeline is in my signature.
Here's the timeline of a friend who has his study VISA already:
Non SDS (Indonesian applying in Indonesia)
College is in DLI list and COVID readiness plan
September 2020 intake
Application submitted: June 27, 2020
BIL: June 28, 2020
Medical request: July 22, 2020
Biometrics done: December 24, 2020 (Huge delay due to VAC closure)
BVL: December 29, 2020
OPR: December 29, 2020
PoE letter: January 8, 2021
It took about a week after he submitted his passport to receiving it back.
Note: not able to share timelines for medical passed, eligibility start etc because he forgot and didn't check it everyday.
