is all of australia on the same time zone
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.
Atlantic Time Zone In Florida, two bills were approved in January 2018 by House and Senate committees, to move most of the state permanently to Atlantic Standard Time (with the panhandle moving to year-round Eastern Standard Time) with no observation of daylight saving time.[7]
