For completeness here is two more state/territory government website links that
uses the Australian government defined format. 

Northern Territory government page:

"The Time Zone in the Northern Territory is Australian Central Standard Time
(ACST, also commonly referred to as CST). ACST is shared by Broken Hill (NSW),
the Northern Territory and South Australia. ACST is 9 hours and 30 minutes ahead
of Coordinated Universal Time (UTC)."
