London to Sydney Time Converter

Data generated: July 31, 2026

London and Sydney sit close to opposite sides of the planet, and the gap between them is the widest of any pair on this site: it ranges from nine to eleven hours depending on the time of year.

That range exists because the two cities are in opposite hemispheres and observe daylight saving time on opposite schedules, so British summer overlaps with Australian winter and vice versa.

For most of the year there is effectively no shared standard working day between London and Sydney, which pushes teams toward early-morning or late-evening calls on one side.

Anyone scheduling regularly between these two cities benefits from checking the current offset rather than assuming it stays fixed.

As of July 31, 2026, Sydney is 9 hours ahead of London (London is UTC+1, Sydney is UTC+10). London is currently on daylight saving time; Sydney is currently not on daylight saving time.
