Samsung Galaxy S3 - NFC TecTiles - Australia

Samsung US have released the TecTiles NFC Tags for the Samsung Galaxy S3.

Can I get them in Australia?
If not, can I purchase them from the US store and will they work on my Australian SGS3?

I sent an email to Samsung Australia, and here is their reply:

"The TecTiles NFC Tags are only available in USA and Canada at the moment and we don't have a release date for it in Australia yet. It will be released once the TecTiles settings are compatible with the network providers in Australia. If you buy it from the US store we can not grantee if its going to work in Australia as there might be a compatibility issue. We suggest wait for TecTiles release in Australia so that there are no compatibility issues. "

Not sure what compatibility issues there might be with carriers when it is a phone hardware thing?

Anyway, I hope they arrive here soon....or maybe someone can send me one from the US to try? ;-)
