Fares bottom out in November around $1,045 and peak in October near $1,554, 49% dearer, across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 20.5 hours outbound, on a 8-night trip — ticketed under Air China, which on a connecting fare need not operate every leg. At $1,045 for 15,976 km each way, that works out to about $33 per 1,000 km flown. That is below the $42 per 1,000 km typical of ultra-long-haul fares here. Across the 33 departure cities we track at a similar distance from Sydney, this fare ranks 14th — 51% above the $690 from Los Angeles. The best time to be in Sydney: Oct–Nov · Mar–Apr.

We do not publish a number for this, because we cannot measure it yet.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 4 months of cached fares, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
The current cheapest fares involve a connection, ticketed under Air China. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
No — these are cached fares found on real searches (this one on 17 October). 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.
