Daylight saving
Some eastern Australian locations move to daylight time, while others do not, so city context matters.
Avoid abbreviation mistakes
Timezone abbreviations are compact, but they are not always unique and they do not always describe daylight saving behavior. For exact meetings, choose a city and date in the converter. That lets the timezone database apply the correct local rules instead of relying on a fixed abbreviation.
