Actually, as far as I know, Australian legislation does not specify
either names or abbreviations for the zones, and various Australians
seem to do as they please.

John Mackin reported in 1991 that Australian Broadcasting Commission
announcers use the phrases `Eastern Standard Time' or `Eastern Summer
Time', and that announcers on the overseas service Radio Australia
prefix the word `Australian' to these phrases.

Some of the other names in that database are questionable, but I'm
afraid I don't have time right now to review it carefully.

Recent tz databases use 'EST' for both zones; this follows the
phraseology reported for ABC.
