Live · accurateWhat is the time difference between the UK and Sydney?
Direct answer. Sydney is 9 to 11 hours ahead of the UK, depending on the time of year.
Sydney is the trickiest major conversion, because Australia’s east coast observes daylight saving in the opposite season to the UK — its summer is our winter, and its clocks go forward as ours go back. The gap is 9 hours during UK summer, 11 hours during UK winter, and passes through 10 hours during the changeover periods.
Key fact: Because the UK and Sydney change clocks in opposite directions, the difference swings between 9, 10 and 11 hours across the year — always use the live converter for an exact time.
