Anzuu,
Your AFP looks exactly like mine!
Here’s what I would do now:
1. Attach a small note to the bottom (in the blank space) of the document and write, “This is the correct AFP using reason code #33. It confirms there are NO DISCLOSABLE OUTCOMES.” Scan it. Resubmit it online to NVC right away.
2. Write an Email to both US Senators from your husband’s home state. Tell them what you have shared here about the AFP problem, twice rejected, once rejected by NVC error, that you just submitted #33 to NVC a second time, what kind of visa you seek and what city/state your American spouse lives. Tell them that apparently Australia updated the appearance of their police check documents and you have been told that some NVC agents might not recognize the new one. Ask for help.
By the way, in what US state does your husband live? You can look up the names of those two Senators online and Email them
I am not an immigration lawyer. I am just a citizen. However, after reading these posts and learning from my own experience, that is what I would do.
Please seek advice from a practicing US immigration lawyer who will guide you best and help you avoid mistakes that cause further delays.
Best wishes!
