Outside of peak travel times, one-way direct flights usually fall between AU$432 and AU$872. Budget options are also available, with the current cheapest fare sitting at AU$297.

Cheapest time to fly to Seoul

The cheapest time to fly to Seoul is March or October (excluding Golden Week at the beginning of the month). Both fall within the shoulder season when flight prices tend to dip. March is just after the busy summer travel period, while October sits between major holiday seasons – plus, the weather is not super cold or crowded during these months, making it a great time to explore Seoul without breaking the bank. 

If finding an affordable flight is your priority, avoid major holiday blocks like the school holidays (end of September to early October, July or April), Golden Week (first week of October), Lunar New Year (late January to early February) or Christmas (December). 

Where is the airport in Seoul?

Incheon International Airport (ICN) is around 50 kms from central Seoul. While it’s a bit of a journey, the airport is well-connected. Just hop onto the AREX (Airport Railroad Express) and you’ll reach Seoul Station in 43 minutes (without stopping) — this is the cheapest and most efficient way to get to and from the airport. 

Visa and passport requirements for Australians flying to Seoul 

Lucky us, Australian passport holders do not need a visa when visiting Seoul for up to 90 days for tourism or business. You won’t need to arrange anything before your trip; just ensure your passport is valid for the duration of your trip, and you’ll be good to go. It really doesn’t get easier than this! 

Time difference between Sydney and Seoul

Sydney is 1 hour ahead of Seoul, so the jetlag isn’t too bad. However, when it’s Daylight Savings, Sydney is 2 hours ahead instead. But not to fret, the time difference is always accounted for in your flight ticket.
