I don't think that anybody wants the tz database to use different 
abbreviations from what is in common use in Australia.

What's blocking this from being *changed* is that we believe that 
the existing abbreviations *are* in common use in Australia, 
but that other abbreviations are also in common use, and we 
have no good way to choose between the two (or more) sets of 
abbreviations, so it seems best to retain the status quo.

If you want change, then it is incumbent on you to demonstrate 
that your preferred abbreviations are either in wider use than 
the alternatives, or have more official government backing than 
the alternatives.  Selective quoting from some web sites does not 
constitute such a demonstration.
