London to Sydney time
Sydney is 11 hours ahead of London. London uses Europe/London (UTC±0); Sydney uses Australia/Sydney (UTC+11).
When the time difference changes

- Sun, Mar 28, 2027: London springs forward an hour. Then Sydney is 10 hours ahead of London.
- Sun, Apr 4, 2027: Sydney falls back an hour. Then Sydney is 9 hours ahead of London.
- Sun, Oct 3, 2027: Sydney springs forward an hour. Then Sydney is 10 hours ahead of London.

- 1 9:00 AM in London = 8:00 PM in Sydney
- 2 7:00 AM in London = 6:00 PM in Sydney
- 3 8:00 AM in London = 7:00 PM in Sydney
