- # Australia
-
- # From John Mackin (March 6, 1991):
- # We in Australia have _never_ referred to DST as `daylight' time.
- # It is called `summer' time. Now by a happy coincidence, `summer'
- # and `standard' happen to start with the same letter; hence, the
- # abbreviation does _not_ change...
- # The legislation does not actually define abbreviations, at least
- # in this State, but the abbreviation is just commonly taken to be the
- # initials of the phrase, and the legislation here uniformly uses
- # the phrase `summer time' and does not use the phrase `daylight
- # time'.
- # Announcers on the Commonwealth radio network, the ABC (for Australian
- # Broadcasting Commission), use the phrases `Eastern Standard Time'
- # or `Eastern Summer Time'. (Note, though, that as I say in the
- # current australasia file, there is really no such thing.) Announcers
- # on its overseas service, Radio Australia, use the same phrases
- # prefixed by the word `Australian' when referring to local times;
- # time announcements on that service, naturally enough, are made in UTC.
-
- # From Arthur David Olson (March 8 1992):
- # Given the above, what's chosen for year-round use is:
- # CST for any place operating at a GMTOFF of 9:30
- # WST for any place operating at a GMTOFF of 8:00
- # EST for any place operating at a GMTOFF of 10:00

- # From Robert Elz (March 6, 1991):
- # I believe that the current start date for DST is "lastSun" in Oct...
- # that changed Oct 89. That is, we're back to the
- # original rule, and that rule currently applies in all the states
- # that have dst, incl Qld. (Certainly it was true in Vic).
- # The file I'm including says that happened in 1988, I think
- # that's incorrect, but I'm not 100% certain.

-
- # From Robert Elz (March 13, 1992):
- # I heard that apparently (or at least, it appears that)
- # South Aus will have an extra 3 weeks daylight saving every even
- # numbered year (from 1990). That's when the Adelaide Festival
- # is on...
-
- # From Robert Elz (March 16, 1992, 00:57:07 +1000):
- # DST didn't end in Adelaide today (yesterday)....
- # But whether it's "4th Sunday" or "2nd last Sunday" I have no idea whatever...
- # (it's just as likely to be "the Sunday we pick for this year"...).
-
- # From Bradley White (April 11, 1994):

- # New South Wales and subjurisdictions have their own ideas of a fun time.
- # Based on law library research by John Mackin (john@basser.cs.su.oz),
- # who notes:
- # In Australia, time is not legislated federally, but rather by the
- # individual states. Thus, while such terms as ``Eastern Standard Time''
- # [I mean, of course, Australian EST, not any other kind] are in common
- # use, _they have NO REAL MEANING_, as they are not defined in the
- # legislation. This is very important to understand.
