Time in Australia Australia uses three main time zones: Australian Western Standard Time (AWST; UTC+08:00), Australian Central Standard Time (ACST; UTC+09:30), and Australian Eastern Standard Time (AEST; UTC+10:00).[1] Time is regulated by the individual state governments,[2] some of which observe daylight saving time (DST). Australia's external territories observe different time zones.
