If your bureau want to use "correct" abbreviations, they should probably start by contacting the various state government departments that actually define the time zones, and ask them what they believe should be used - as best we have ever been able to tell, there are no defined zone name abbreviations anywhere, just full names, which essentially never have "Australian" in their names (which makes sense, none of the state governments could really define what is Australian time after all) and in most cases, use Summer Time as the name for the time when Standard Time does not apply (not Daylight Savings Time).

From the New South Wales (NSW) government website:
"Where Daylight saving is observed NSW, ACT,Vic and Tas move from AEST to Australian Eastern Daylight Time (AEDT), and clocks are advanced to UTC +11. SA and the NSW town of Broken Hill move from ACST to Australian Central Daylight Time (ACDT), and clocks are advanced to UTC +10 ½. Daylight saving is not observed in Queensland, the Northern Territory or Western Australia." http://communityrelations.lawlink.nsw.gov.au/cru/daylight/definitions_of_tim...
From the Victorian (Vic) government website:
"Move your clock backward one hour at 3am (Daylight Saving Time)" http://www.business.vic.gov.au/operating-a-business/how-to-start/trading-hou... "Question: What is the time difference between Victoria and Western Australia?: Answer: There are three timezones across Australia. Information about the time observed in these zones can be found on the Australian Government website. " http://ask.vic.gov.au/FA/Hybrid/Themes/infovic/displayresult.asp?MesId=11134...
From the Tasmania (Tas) government website:
While they don’t use abbreviations for the eastern states they do reference the WA timezone using the format specified on the Australian government website. "As a result, Western Australia will not observe daylight saving and will remain on Australian Western Standard Time (AWST) all year." http://www.dpac.tas.gov.au/divisions/policy/daylightsavings
From the South Australian government website:
While I couldn't find any abbreviations on their website but 3/4 is a pretty good argument to change the status quo. http://www.safework.sa.gov.au/show_page.jsp?id=2675
