I know that the USPS stopped shipping first class packages to AU last year. A customer messaged me that they have lifted the suspension (3/30/2022). I went looking to see if that was the case but couldn’t find anything. False Flag?
So I found this relevant article that talks this topic. We’ve noticed many seller state on their store page that they are currently not offering international shipping to AU because of this suspension.
I’d advise to contact the AU postal services and have them deliver an official statement of their current status. I hope this helped!
Thanks. The issue, I believe, is that the USPS will return any packages mailed to AU so it needs to come from them.
The best source of information is the USPS directly through their International Service Alerts page. https://about.usps.com/newsroom/service-alerts/international/welcome.htm
