Following a few inquiries, we just thought to repeat this news that since 1st July 2021 BVE applications (subclass 050 and subclass 051) cannot be submitted by email as they will be treated as invalid applications.
The Department had notified that from 01 July 2021, eligible applicants should submit their BVE application online through ImmiAccount or through the post to the nearest Australian Visa and Citizenship Office. Any application received by the Department email on or after 01 July 2021 will be invalid.
