I think that the Australian people would be better served by
abbreviations that differentiate between standard/winter time and
daylight/summer time. But, I think that users of the tz database
are better served by abbreviations that follow what Australian
people actually use, whether or not those abbreviations are
logical, or ambiguous, or differentiate between standard/winter
time and daylight/summer time.

I was under the impression that "Eastern Summer Time" was the
official name used in the relevant state legislation, and that
"EST" is the obvious and common abbreviation for that name. If
the Australian people really use "EDT" or "AEDT" in preference
to "EST" then (a) it would be nice if there was a relatively
unbiased survey to demonstrate that, and (b) after the result is
demonstrated, but not before, it would be sensible for the tz
database to follow suit.
