How the difference works
Sydney uses Australia/Sydney (UTC+10 standard time) and London uses Europe/London (UTC+0 standard time) — a standard-time gap of 10 hours behind Sydney. Both cities observe daylight saving time, but they switch on different dates, so the gap can temporarily change around those transitions.
Distance: about 16,994 km (10,560 mi) great-circle distance.
