Seoul packs palace-hopping in Bukchon, K-pop and shopping in Myeongdong, and some of Asia's best street food into one genuinely easy-to-reach city from Sydney – a straightforward overnight nonstop with no connections to plan around.

Which airlines fly direct from Sydney to Seoul?

This is a well-served nonstop route with a real mix of full-service and budget options.

• Korean Air – flies nonstop daily, with checked baggage, meals and SKYPASS points included as standard.
• Asiana Airlines – the other full-service nonstop operator, running several flights a week with a similarly complete fare.
• Jetstar – the budget option on this pairing, with baggage, meals and seat selection priced separately from the base fare.
• T'way Air – a Korean low-cost carrier also flying nonstop, similarly unbundled on inclusions.

All four fly directly into Incheon International Airport, so there's no hub-hopping required on this route.

Flight time from Sydney to Seoul?

The nonstop flight takes about 10 hours 30 minutes in the air, typically departing Sydney in the evening and landing in Seoul the next morning – a straightforward red-eye rather than a multi-leg journey.

Average price of flights between Sydney and Seoul

Fares vary noticeably by carrier, with Jetstar and T'way Air's base fares generally undercutting Korean Air and Asiana's bundled pricing before add-ons are factored in. One-way tickets on Traveloka start from around AU$366 outside peak periods, with Australian school holidays and Korea's Lunar New Year (Seollal) pushing prices up across all four carriers.

Cheapest time to fly to Seoul

Fares tend to ease in the shoulder months outside Australian school holidays, Seollal and Chuseok (Korea's autumn harvest festival), when both leisure and domestic Korean travel demand ease off together. Autumn (September-November) is also a popular time to visit for the foliage, so booking well ahead helps for that window specifically.

Where is the airport in Seoul?

Incheon International Airport (ICN) sits about 48 kilometres west of central Seoul. The AREX express train is the fastest option, reaching Seoul Station in around 43 to 53 minutes depending on the service, while airport buses and taxis take roughly 60 to 90 minutes depending on traffic.

Visa and passport requirements for Australians flying to Seoul

Australians currently don't need a Korea Electronic Travel Authorisation (K-ETA) to enter South Korea, under a temporary exemption extended through 31 December 2026 for stays of up to 90 days. Travellers entering without a K-ETA instead need to submit a digital e-Arrival Card online within three days of arrival. Given this exemption has been extended year to year, it's worth reconfirming it's still current closer to your travel dates. A passport valid for at least six months beyond arrival is also required. Smartraveller advises exercising normal safety precautions in South Korea, its standard baseline advice for the country.

Time difference between Sydney and Seoul

Seoul runs on Korea Standard Time (UTC+9) year-round, with no daylight saving. Sydney sits one hour ahead on Australian Eastern Standard Time, widening to two hours ahead whenever daylight saving is in effect over the Australian summer.

Our tips for getting the best price on flights

• Compare Jetstar and T'way Air's base fares against Korean Air and Asiana's bundled pricing once you add baggage and seat selection.
• Avoid booking around Seollal and Chuseok if your dates are flexible, since domestic Korean travel demand spikes hard during both.
• Book 6 to 10 weeks ahead, especially for the popular autumn foliage season, and set a Price Alert to track fares.

• Price Alert flags genuine fare drops so you don't have to check back manually.
