Both South Korea and Australia sit in Asia & Pacific, but their tax structures take different paths. On a $90,000 gross, the effective tax burden in Australia is roughly 9.5% higher than in South Korea — driven by differences in 4대보험 vs Medicare, bracket structure, and personal allowance.
Same nominal gross applied to both tax systems. Currencies aren't FX-converted — compare structures, not purchasing power.
South Korea uses an eight-band income tax with a top rate of 45%, plus a 10% local income tax. The four mandatory insurances — national pension, health, employment, and long-term care — total around 9.4% for the employee. A standard earned-income deduction reduces the taxable base substantially.
Australia has a tax-free threshold of A$18,200 and four progressive brackets. The 2% Medicare Levy funds public healthcare; high earners without private cover pay an additional Medicare Levy Surcharge. Superannuation (currently 11.5%) is paid by the employer on top of gross salary, so it doesn't reduce take-home pay.
