Fares bottom out in March around $414 and peak in January near $565, 36% dearer, across the 9 months we track. The cheapest itinerary we are tracking flies Scoot nonstop and takes about 8 hours outbound, on a 14-night trip. At $414 for 6,306 km each way, that works out to about $33 per 1,000 km flown. That is below the $44 per 1,000 km typical of long-haul fares here. Of the 9 departure cities we track at a similar distance from Sydney, this is the cheapest right now — 6% under the next one, Manila. That puts it in the cheaper half of the 11 routes of similar length we watch out of Singapore, where the middle fare is $576. The best time to be in Sydney: Oct–Nov · Mar–Apr.

Route facts
Good to know
Only slightly. The seasonal median is around $480 round-trip and this fare is 14% under it. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
Across 9 months of cached-fare history, Mar 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.
We do not publish a number for this, because we cannot measure it yet.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, Mar comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Yes — the current board includes nonstop fares (Scoot). The outbound leg runs around 8 hours.
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.
