How Time Zone Conversion Works
Time zone conversion works by comparing the UTC offset of one location to another. Every city or region is measured relative to Coordinated Universal Time (UTC), which acts as the global reference point for civil time.
AWST is 1 hour 30 minutes behind ACST (standard time).
Daylight Saving Time: ACST observes DST; AWST does not. The offset between them shifts by 1 hour twice a year — in spring and autumn — when ACST changes its clocks.

South Australia observes DST (ACDT, UTC+10:30); the Northern Territory remains on ACST year-round. SA has used the same Sunday transition dates as the eastern states since the 2008/09 DST season — older sources stating SA changes one week later are out of date.
AWST · Western Australia Time
Standard offset +08:00
Western Australia Time remains on a constant standard offset for the year.
Western Australia does not observe DST; state referendums have repeatedly rejected permanent daylight saving.
