+1 me for changing to AEST, AEDT and so on.

I encourage you to read through a relatively recent discussion about
this. I straw-polled our Unix users' group's mailing list:
. If you'll excuse the deviation to a discussion of whether various
places should have daylight saving time, you'll see a preference for
AEST: I count 6 for and 1 possibly against.

"Australian" is presumed for an Australian radio broadcast; for computer
use there is no regional context. At any rate, the discussion should
focus on the *abbreviations* rather than the full names because only the
abbreviations are specified by the timezone database.

I'm not convinced that searching the web for "EST" is a valid survey,
particularly as it is a common abbreviation for "estimate" or
"established". There are also websites such as Flickr that use EST but
there is evidence that this is simply a result of using the timezone
database: a feedback loop. I wonder to what extent the timezone database
is seen as an authority for what people use.
