Cached-fare history: across 9 months, Nov is the cheapest for LON → SYD. Best time to be there: Oct–Nov · Mar–Apr.
Fares bottom out in November around $836 and peak in March near $1,441 — a $605 spread across the 9 months we track. The cheapest itinerary we are tracking makes one stop and takes about 21 hours outbound, on a 18-night trip — ticketed under Air China, which on a connecting fare need not operate every leg. At $836 for 16,994 km each way, that works out to about $25 per 1,000 km flown. That is well under the $40 that ultra-long-haul fares on this board typically run. Across the 30 departure cities we track at a similar distance from Sydney, this fare ranks 2nd — 0% above the $833 from Stockholm.

What is the cheapest month to fly from London to Sydney?
Across 9 months of cached-fare history, Nov comes out cheapest on this route. The best months to actually be in Sydney are Oct–Nov · Mar–Apr — when those overlap, that's your window.
How far in advance should I book LON → Sydney?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. What we can measure is which month is cheap: across 9 months of cached fares, Nov comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from London to Sydney?
The current cheapest fares involve a connection, ticketed under Air China. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on September 1). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
