Sorry for the late answer.

There is a "set preferred language" button on the main page but this is next to the older downloads for 14 and 13 but as these were also INT it doesn't change anything.
If you select ArchiCAD 16 International version, there should be ArchiCAD 16 Australian version right under it. If it is not available, please send us a picture of your product page to this address: myarchicad at graphisoft dot com

Could INT be an option next to everyone's localised version?
International version is not sold in every country and the main problem that it is not supported. This is the reason why we have some restrictions on MyArchiCAD.
