What is ACST in AEST?

Australian Eastern Time is 30 minutes ahead

Australian Central Time is on UTC+10:30 and Australian Eastern Time is on UTC+11:00 right now. Both are on daylight saving, so their clocks read ACDT and AEDT. That gap holds all year, because both zones change their clocks on the same dates.

Scheduling between the two

Working hours overlap from 9:00 am to 6:00 pm ACDT, which is 9:30 am to 6:30 pm AEDT. Anything inside that window falls in the normal working day at both ends.

Australian Central Time (ACDT) is used in South Australia and the Northern Territory, on a half-hour offset from the east coast

Australian Eastern Time (AEDT) is used in Melbourne, Canberra and Brisbane. Queensland stays on AEST all year while the southern states move to AEDT.
