Considering the enormous amount of mail traffic between the US and Australia and its importance, with regard to the suspensions listed in the link Aus Post should have been the first to know. Not so
I have contacted Aus Post with your link and their international dept. confirms that they have not been informed by USPS of any suspension either officially or not.
Why would this be implemented to a country such as Australia? From your link check the company that she keeps:
Cuba, and so forth.
Obviously the USPS.com site has been hacked and the information is bogus. If you doubt it contact USPS in person and ask them.
We routinely ship products to our international customers via USPS First Class International Package*.
Presently, USPS has paused shipping to Australia. This suspension is due to COVID-19 transportation cancellations and restrictions.
We apologize to our valued Australian customers for any inconvenience and disappointment.
Australia is not the only country affected. Here is a link to the USPS alert notification webpage which shows which locations are presently not being served by USPS: https://faq.usps.com/s/article/Mail-Service-Alerts-and-Updates
The USPS website states: "Customers are asked to refrain from mailing the following services to Australia until further notice:
- First-Class Package International Service® (FCPIS)
- Commercial ePacket (CeP)
- International Priority Airmail (IPA) Packets
- International Surface Air Lift (ISAL) Packets
"Postal Service employees endorse them “Mail Service Suspended — Return to Sender” and then place them in the mail stream for return."
Hopefully, conditions will quickly improve and First Class shipping will resume to Australia.
Best wishes to all adversely affected by COVID-19.
* We ship internationally using USPS First Class International Package because it is the least expensive shipping option available to us.
