When this route gets cheap.
Fares bottom out in February around $597 and peak in January near $725, 21% dearer, across the 9 months we track. The cheapest itinerary we are tracking makes one stop and takes about 11 hours outbound, on a 4-night trip — ticketed under Cebu Pacific, which on a connecting fare need not operate every leg. At $597 for 7,375 km each way, that works out to about $40 per 1,000 km flown. That is below the $44 per 1,000 km typical of long-haul fares here. Across the 9 departure cities we track at a similar distance from Sydney, this fare ranks 9th — 44% above the $414 from Singapore. That puts it in the cheaper half of the 26 routes of similar length we watch out of Hong Kong, where the middle fare is $830. The best time to be in Sydney: Oct–Nov · Mar–Apr.

Good to know
HKG → SYD, answered.
Is $597 a good price for Hong Kong to Sydney?
Only slightly. The seasonal median is around $640 round-trip and this fare is 7% 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.
What is the cheapest month to fly from Hong Kong to Sydney?
Across 9 months of cached-fare history, Feb 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 HKG → 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We do not publish a number for this, because we cannot measure it yet.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, Feb comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Hong Kong to Sydney?
The current cheapest fares involve a connection, ticketed under Cebu Pacific. 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.
