Short names are only used where they are commonly understood, e.g. "HNR" is only used in Canadian French, European French uses "UTC-7" in the short format (but "heure normale des Rocheuses" in the long format).

And it has "Australian {Central,Central Western,Eastern,Western} Standard Time", "Australian {Central,Central Western,Eastern,Western} Time", and "Australian {Central,Central Western,Eastern,Western} Daylight Time" for standard time, generic time, and daylight saving time, respectively, for various regions of Australia. (It doesn't provide abbreviations for any of them.)
