When this route gets cheap.
Fares bottom out in March around $1,083 and peak in December near $1,522, 41% dearer, across the 5 months we track. The cheapest itinerary we are tracking makes 2 stops and takes about 23 hours outbound, on a 26-night trip — ticketed under Ryanair, which on a connecting fare need not operate every leg. At $1,083 for 18,177 km each way, that works out to about $30 per 1,000 km flown. That is below the $42 per 1,000 km typical of ultra-long-haul fares here. Across the 28 departure cities we track at a similar distance from Sydney, this fare ranks 14th — 48% above the $731 from London. The best time to be in Sydney: Oct–Nov · Mar–Apr.

Good to know
LIS → SYD, answered.
Is $1,083 a good price for Lisbon to Sydney?
Only slightly. The seasonal median is around $1,265 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.
What is the cheapest month to fly from Lisbon to Sydney?
Across 5 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.
How far in advance should I book LIS → 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We do not publish a number for this, because we cannot measure it yet.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 5 months of cached fares, Mar comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Lisbon to Sydney?
The current cheapest fares involve a connection, ticketed under Ryanair. 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.
