I am an August 2019 applicant and when we made application there is nothing about primary applicants English certification. I've made everything true but they changed the rules on May and wanted English certificate from primary applicant. While I am waiting IELTS date, case officer contacted me and asked the English certificate and 17th of June I uploaded it. Still waiting. I made all process true and still waiting. It is not fair. I am obsessive and I always check the lists many times before I made an application and take screenshots of every step. You can check before and after screenshots. I lost faith to the department. Australian immigration system for me is a big disappointment.
