When this route gets cheap.
Fares bottom out in November around $484 and peak in December near $1,136, 135% dearer, across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 12 hours outbound, on a 9-night trip — ticketed under Xiamen Airlines, which on a connecting fare need not operate every leg. At $484 for 7,767 km each way, that works out to about $31 per 1,000 km flown. That is below the $44 per 1,000 km typical of long-haul fares here. Across the 18 departure cities we track at a similar distance from Hanoi, this fare ranks 3rd — 4% above the $467 from Brussels. That puts it in the cheaper half of the 18 routes of similar length we watch out of Sydney, where the middle fare is $536. The best time to be in Hanoi: Oct–Nov · Mar–Apr.

Good to know
SYD → HAN, answered.
Is $484 a good price for Sydney to Hanoi?
Yes — the seasonal median for this route is around $885 round-trip. At $484 you're 45% below that, which we rate rare for this route.
What is the cheapest month to fly from Sydney to Hanoi?
Across 4 months of cached-fare history, Nov comes out cheapest on this route. The best months to actually be in Hanoi are Oct–Nov · Mar–Apr — when those overlap, that's your window.
How far in advance should I book SYD → Hanoi?
We do not publish a number for this, because we cannot measure it yet.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.
Are there nonstop flights from Sydney to Hanoi?
The current cheapest fares involve a connection, ticketed under Xiamen Airlines. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
Are these prices guaranteed?
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.
