OVERVIEW
Australia and South Korea have a major Working Holiday Maker (WHM) corridor — South Korea is one of Australia's largest sources of WHM visa holders (young Koreans working in Australia), while Australian backpackers frequently visit Korea. Tax-wise, both have 45% top national income tax rates, but Korea's 10% local surcharge pushes the effective rate to 49.5%. Australia's social structure is different: 2% Medicare + 12% employer-funded superannuation (not from gross wages). On income tax plus employee social contributions the two countries come out close: within about A$1,700 up to A$200,000 (Korea about A$1,100 cheaper at A$100,000, Australia about A$1,000 to A$1,700 cheaper at A$150,000 to A$200,000) and Korea about A$1,400 cheaper at A$300,000. Korean figures are converted at roughly KRW 1,000 per A$1 (approximate). Australia's 12% super is employer-paid on top of wages.

FAQ

Frequently Asked Questions

Is there an Australia-South Korea tax treaty?

Yes. Australia and South Korea signed a DTA in 1982, updated. The treaty prevents double taxation on employment income, dividends, interest, and royalties. Australians working in Korea pay Korean income tax; Koreans working in Australia pay Australian tax. Both countries allow credit for tax paid in the other country to prevent double taxation.

How does the Australia-Korea Working Holiday Maker visa work for taxes?

Korean citizens aged 18–30 can apply for an Australian WHM visa (subclass 417) for a 12-month working holiday. WHM tax rates in Australia changed in 2017 — WHM holders pay 15% on all income up to $45,000 (rather than the progressive resident rate), then regular rates above that. No tax-free threshold for WHM holders. Australian WHM for Koreans is one of the most popular destination-nationality combinations.

What is Australian superannuation for Korean workers?

Australian employers must pay 12% (FY2025-26) superannuation on top of wages to a complying super fund. Korean employees working in Australia under an employment arrangement are entitled to super. Upon leaving Australia permanently, temporary visa holders can claim their super back through the Departing Australia Superannuation Payment (DASP) — subject to 35% withholding tax for temporary residents.

How does Korean NHI compare to Australian Medicare?

Both provide universal healthcare. Korean NHI covers hospital and most outpatient care at co-pays of approximately 10%–20%; employee contribution 3.595% of salary plus about 0.47% for long-term care (employer matches). Australian Medicare is funded by a 2% levy and covers hospital and most GP services; specialist and dental largely out-of-pocket or private insurance. OECD data consistently shows Korean NHI achieves better hospital outcomes per dollar spent, but Australian Medicare has better bulk-billing GP access for preventive care.

What is the Korean National Pension (NPS) vs Australian superannuation?

Both are mandatory retirement savings systems. Korean NPS: 4.75% employee + 4.75% employer = 9.5% total (2026); provides a defined benefit pension at age 63 (rising). Australian Super: 12% employer only; individually invested; accessible from age 60 as a defined contribution. Australian super funds have historically returned ~7–8%/year long-term; the compounding effect makes Australian super significantly more generous than NPS for equivalent income levels.

Do Koreans who worked in Australia get their super back?

Yes, via DASP (Departing Australia Superannuation Payment). Temporary visa holders who have left Australia permanently can claim their accumulated super. The DASP is taxed at 35% for temporary residents — a significant withholding. Australian citizens and permanent residents retain their super until preservation age (60). Koreans who subsequently become Australian permanent residents or citizens cannot claim DASP — super stays until 60.
