Flights from London to Sydney
London to Sydney (LHR–SYD) is the classic "Kangaroo Route" — historically the long-haul benchmark between the UK and Australia. As of July 2026 there is no scheduled nonstop; every itinerary makes one stop at a hub such as Singapore, Dubai or Doha. That is set to change: Qantas has confirmed a nonstop service launching in October 2027. Use Flyroz to compare live fares, then book directly with the airline or travel site.

Estimated journey duration
There is no nonstop LHR–SYD service today. One-stop itineraries typically run about 22–24 hours door-to-door including the transit stop — for example Qantas's flagship QF1/QF2 routes via Singapore, where the whole journey including the roughly 2-hour Singapore transit takes about 24 hours (Point Hacks; Australian Frequent Flyer, accessed 2026-07-11). When Qantas's nonstop begins in October 2027 it is expected to take up to about 22 hours (Qantas, June 2026; corroborated by Aviation Week and Simple Flying).
Airlines and current route context
With no nonstop currently operating, the route is served by one-stop carriers routing through their home hubs: Qantas via Singapore (QF1/QF2), Emirates via Dubai, Qatar Airways via Doha, and Singapore Airlines via Singapore (Point Hacks and Trip.com fare/routing data, accessed 2026-07-11). From October 2027 Qantas plans to add the world's-longest nonstop on a purpose-built Airbus A350-1000ULR, with fares going on sale in February 2027 (Qantas, June 2026).
