--- Comment #4 from Jens Petersen petersen@redhat.com --- The only way to get en_AU is to select it! :)
Your step (1) decides the locale not the timezone.
It would be nice if we could decouple language and region from locales but that is not how glibc locales work alas.
Second related problem is getting en_AU to fallback to en_GB translations rather than en_US.
