Time difference & DST
Australian Eastern Standard Time runs 15 hours ahead of Eastern Standard Time, moving to 16 hours ahead during Sydney's summer when the eastern Australian states observe daylight saving time. For US East Coast teams, this is one of the widest practical gaps in commercial coordination.
New South Wales, Victoria, ACT and Tasmania observe DST from early October to early April (AEDT, UTC+11); Queensland stays on AEST year-round. Combined with the US flipping on the opposite calendar, the effective offset can swing between 13 and 16 hours across a single year.
Best time to schedule a call
The most humane overlap is a Sydney morning / New York evening exchange. 6:30 PM EST corresponds to roughly 9:30 AM AEST the following day — early enough for New York, and comfortably within the Australian workday.
