South Korean passport holders need an ETA (Electronic Travel Authority, subclass 601) to enter Australia. Apply through the Australian ETA app (iOS/Android) for AUD 20. Processing is near-instant in most cases but can take up to 12 hours. The ETA is valid for 12 months with multiple entries, each stay up to 90 days. Passport must be valid for the duration of your stay. The ETA is linked electronically to your passport, so no printout is needed.
If the ETA app does not work (some users report technical issues), apply for a Visitor Visa (subclass 600) at immi.homeaffairs.gov.au for AUD 190, allowing stays up to 3, 6, or 12 months. Processing takes 1 to 4 weeks. At Australian immigration, you clear SmartGate (automated) if your passport has a chip, which takes about 2 minutes. Declare all food, plant material, wooden items, and animal products. Australia's biosecurity fines start at AUD 626.
