About Sydney Time: AEST & AEDT
Sydney operates on the Australia/Sydney timezone, switching between AEST (Australian Eastern Standard Time, UTC +10:00) during winter and AEDT (Australian Eastern Daylight Time, UTC +11:00) during summer. Critically, Australia's DST runs in the opposite season from the Northern Hemisphere — clocks move forward in October and back in April. This means Sydney is ahead of most of the world for more than half the year.
The Australian Securities Exchange (ASX) opens at 10:00 AM and closes at 4:00 PM AEST/AEDT. When Sydney's market opens, Tokyo is already past midday, Singapore is at 8:00–9:00 AM, and London is in the middle of the night (midnight to 1:00 AM). This makes Sydney the first major financial centre to open each trading day, setting early price signals for Asian markets.
Scheduling from Sydney is challenging for transatlantic teams. London (GMT) is 10 hours behind Sydney in AEST and 11 hours behind during AEDT — meaning almost no business hours overlap. The only viable window is Sydney's early morning (7:00–9:00 AM AEST), which aligns with London's previous evening (9:00–11:00 PM GMT). New York (EST) is 15–16 hours behind Sydney, making live collaboration practically impossible during standard hours. Sydney teams working with US clients often accept that one side will work outside normal hours.
Within Australia, DST is not universal — Queensland (Brisbane) does not observe DST, remaining on AEST (UTC +10:00) year-round. This creates a persistent 1-hour gap between Sydney and Brisbane during Australian summer (roughly October to April), which regularly catches people off guard when scheduling domestic Australian meetings.
