Best time to be in Sydney: Oct–Nov · Mar–Apr. Fare history for this route is still thin, so we make no seasonal call yet.
The cheapest itinerary we are tracking makes 3 stops and takes about 24 hours outbound, on a 20-night trip — ticketed under Ethiopian, which on a connecting fare need not operate every leg. At $1,096 for 15,326 km each way, that works out to about $36 per 1,000 km flown. That is below the $40 typical of ultra-long-haul fares here. Across the 34 departure cities we track at a similar distance from Sydney, this fare ranks 17th — 35% above the $814 from Los Angeles. We have 2 months of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage.

ATH → SYD, answered.
How far in advance should I book ATH → 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We do not publish a number for this, because we cannot measure it yet.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. See /guides/what-moves-a-flight-price/ for the levers we can measure.
Are there nonstop flights from Athens to Sydney?
The current cheapest fares involve a connection, ticketed under Ethiopian. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on September 1). 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.
