A like-for-like view of salary after income tax and employee contributions, calculated locally in GBP and AUD.
Compare the same gross salary in up to four countries. Annual figures assume a full year of income.
Planning FX assumptions dated 4 September 2026; not live quotes or a verified historical price series. Edit the USD value of one currency unit.
About these assumptionsGross salaries are expressed in US dollars, converted to local currency and then taxed. The higher net result at each level is marked.
USD equivalents use planning FX assumptions dated 4 September 2026; these are not live market quotes. Refine personal assumptions in the calculator above.
At a $100,000 gross equivalent, the model leaves about $3,806 more after modelled employee deductions in Australia. That difference reflects the stored resident-employee scenarios; it is not a cost-of-living or job-market conclusion.
The answer depends on salary: United Kingdom leaves more below roughly $27,000 gross, and Australia leaves more above it, because the two schedules progress at different speeds.

At an equivalent gross amount, the comparison isolates the effect of the two modelled tax systems. It does not claim that the same role commands the same exchange-rate salary in both countries.
