Time difference from the UK
Because the UK and Australia change their clocks in opposite seasons, Sydney is 9 hours ahead of the UK during the UK summer, and up to 11 hours ahead during the UK winter. For short overlap periods when only one side has changed its clocks, the gap sits at around 10 hours.
When it is 3pm in the UK, it is normally 12am in Sydney.
Best time to call
Early morning UK time (around 7am-9am) usually matches Sydney's evening, which tends to be the easiest overlap for a call. Sydney working hours generally fall in the UK's overnight, so plan ahead if you need to reach someone during their office day.
Good to know
- Sydney observes daylight saving from around October to April - the reverse of the UK, since Australia is in the southern hemisphere.
- The 9-to-11-hour range means it is always worth double-checking the exact gap close to the UK's or Australia's clock-change weekends.
