Prodded by a note from Bradley White on Queensland abandoning DST,
after a review of the last year-and-a-half's worth of correspondence,
and having mulled things over in the bathtub,
the attached is the best I can do on what Australasia is like at the moment.
There's something here to offend everyone; I'm eager for suggestions.

# 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 used below year-round 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
