Anyone who says remove Tod from moderating this group, should leave the group and get poor confusing advice from one of the other visa advice groups. Easy decision.
I think you are confusing 90 day reporting and renewing extension. Looking at the photos, your visa extension is valid until Feb 2022, and the other paper Nov 21 I think is your 90 day report date. You do not need to have 400k seasoned in a bank for 90 day reporting.
Most immi offices for 90 day reporting need original and copied of passport, stamps/visa, TM6, TM30, last 90 day report.
