Frequently Asked Questions
What is the time difference between UTC and AEST?
During standard time, Australian Eastern Standard Time is 10 hours ahead of Coordinated Universal Time.
Does all of eastern Australia observe Daylight Saving Time?
No — eastern Australia is split on DST. New South Wales (Sydney), Victoria (Melbourne), Tasmania (Hobart), and the ACT (Canberra) advance their clocks to AEDT (UTC+11) each October, while Queensland (Brisbane) opts out entirely and remains on AEST (UTC+10) year-round. This means Sydney and Brisbane run on the same clock for only part of the year.
What is the difference between AEST and AEDT?
AEST (Australian Eastern Standard Time) is the UTC+10:00 offset observed during the Southern Hemisphere winter months, roughly April through October. AEDT (Australian Eastern Daylight Time) is the UTC+11:00 offset applied during the Southern Hemisphere summer when clocks spring forward in October, observed by New South Wales, Victoria, Tasmania, and the ACT.
