Hi @ScottAus 

Thanks for posting your observation to TP-Link Business Forums.

Regarding the firmware issue, you'd better check on the sticker attached on the actual EAP itself. It will detail the exact regional version (EU or AU).

If the sticker saying your EAP is an EU version AP, then you can try upgrading it to the EU firmware.

Additionally, though the AU website released some mixed AU & EU firmware, it sometimes does not means it will convert AU EAP to EU EAP, but likely the firmware now is universal. They are still following the AU regulations or laws.

And here's the article of how to upgrade EAP firmware in different management methods: How to upgrade EAP firmware in different management modes | TP-Link

Thanks @Gabriel-TP,  this was the point i was trying to make,  why when i go to the AU site is it listing EU firmware at all?

If i select a EU country and list the firmware for the EAP673 v1 it only gives me EU firmware.

if i select US as the country i only see US firmware.

So why does AU site show both AU and EU?
