If I recall correctly, the last time I checked,
different parts of the Australian national government
used different terminology and/or abbreviations and
nobody seemed to be in charge.

This area of confusion is not new, by the way:

   The ABC could not be more or less explicit than it was
   in the term "Eastern Australian daylight saving time,"
   said an official of the commission yesterday, when replying
   to a statement by a correspondent of The Argus, that the
   phrase was cumbersome....  The suggestion that the ABC should
   adopt the term "Eastern summer time" was unsatisfactory...

     1942-10-07, page 5, col. 2.
