London to Sydney meeting time — find the best time to meet across GMT & AEST.
London–Sydney is the classic 'antipodean problem': nine to eleven hours ahead, Sydney's working day happens while London sleeps. There is no natural 9-to-5 intersection — yet thousands of UK-Australian teams collaborate daily by widening one edge and protecting the other. This page shows you exactly where the day bends.

Scheduling tips for London ↔ Sydney
- The least-bad bridge: London 8:00–10:00 AM catches Sydney 7:00–9:00 PM same-day evening in the northern winter (5:00–7:00 PM in the northern summer) — ideal for handovers.
- Alternatively London up to 6:00 PM meets Sydney next-day 4:00–5:00 AM only for the truly committed; avoid making it habitual.
- Asymmetric hours are the only fix: start London at 8:00 AM and let Sydney finish at 7:00 PM; there is no midday overlap to negotiate.
Bridging an impossible gap
With standard 9-to-5 hours these two cities have no mutual working window. Extend one side: an 8:00–9:00 AM London call lands at 7:00–8:00 PM in Sydney in the northern winter (5:00–6:00 PM in the northern summer) — the standard UK↔Australia handover. Set Sydney's row to end at 6:00 PM and London's to start at 8:00 AM in the planner above to see the manufactured overlap appear.

London – Sydney FAQ
What time is 9 AM GMT in Sydney?
9:00 AM GMT is 8:00 PM AEDT in the Australian summer or 7:00 PM AEST in winter — evening the same calendar day, since Sydney runs close to half a day ahead.
Is there any overlap between London and Sydney working hours?
Not with strict 9-to-5s on both sides. Teams bridge the gap by extending London into early morning or Sydney into evening — typically a 8–10 AM London / 7–9 PM Sydney channel.
How far ahead is Sydney from London?
Nine to eleven hours, depending on which side is on daylight saving: nine when London is on BST and Sydney on AEST, ten in the mixed alignments, and eleven when London is on GMT and Sydney on AEDT. The exact figure flips as the two countries change clocks on opposite schedules.
