We ran A$80,000 through Australia's 2024–25 tax system for every state and territory. Unlike the US, the result is identical everywhere — but what that paycheck buys you varies by up to A$16,500 a year.
State income tax is a major source of financial inequality in countries like the United States. In Australia, it simply doesn't exist. The ATO collects income tax under a single national system — your employer, your salary, your state of residence make no difference to the calculation. A nurse earning A$80,000 in Darwin takes home exactly the same after-tax pay as a nurse earning A$80,000 in Sydney.
Below is the complete picture: the uniform federal tax breakdown on A$80,000, what the paycheck buys in each state after adjusting for cost of living, and what this means for career decisions and interstate moves.
Australia's constitution gives income taxing power exclusively to the Commonwealth. States fund their budgets through payroll tax (paid by employers, not employees), stamp duty, land tax, and GST distributions — none of which reduce your take-home pay from a salary.
Take-home pay is A$61,933 in every state. Sorted by purchasing power — how far that paycheck goes after adjusting for each state's cost of living. Click any column header to re-sort.

Take-home pay is identical in all states — Australia has no state income tax. CoL index: national average = 100; higher index = more expensive. Purchasing power = A$61,933 ÷ CoL index × 100 (effective A$ equivalent at national average prices). CoL estimates are based on ABS price data and published cost-of-living research; treat as indicative, not precise. Superannuation (11.5% employer contribution) is not deducted from take-home pay under standard salary arrangements. Figures assume an Australian resident with no salary sacrifice or other deductions. Not tax advice.
When Australia's federation was formed in 1901, the constitution granted income taxing powers to both the Commonwealth and the states. During World War II, a High Court ruling effectively nationalised income tax collection — and it was never reversed. Today, the ATO administers a single set of brackets for all 26 million Australians, from Thursday Island to the Nullarbor Plain.
This is the most important fact for any Australian salary comparison: your state of residence has zero effect on your income tax bill. A software engineer moving from Melbourne to Brisbane for a lifestyle change does not get a pay rise from lower state taxes — they get the same take-home they had before. The only "tax gain" from moving interstate is indirect: if the cost of living in the new state is lower, your purchasing power improves.
On A$80,000, Australian residents keep A$61,933 after federal income tax and the Medicare levy — 77.4% of their gross salary. What that A$61,933 buys depends heavily on where they live. ABS data and independent cost-of-living research consistently show Sydney and the ACT as Australia's most expensive jurisdictions, while Tasmania and South Australia offer the lowest costs for housing, goods, and services.
The gap is substantial. In Tasmania (CoL index ~88 vs national average of 100), A$61,933 has the effective purchasing power of roughly A$70,000 at national average prices. In Sydney (index ~115), the same income feels closer to A$54,000. That's a gap of approximately A$16,000 in real living standards from the same nominal paycheck — comparable to the interstate income tax gap the US experiences on a $75,000 salary.
Western Australia is a consistent outlier in Australian salary data. Average full-time earnings in WA consistently rank among the highest in the nation — driven by the resources and mining sectors that underpin the state's economy. Workers in WA who earn more than the A$80,000 study salary benefit from this significantly, but the state's cost of living (particularly in Perth) has risen substantially through the mining booms, eroding some of the purchasing power advantage.
The Australian Capital Territory has both the highest average wages in the country (driven by the public service concentration) and some of the highest costs of living. On a A$80,000 salary, Canberra sits near the bottom of the purchasing power table despite strong economic fundamentals — A$80,000 is relatively modest by ACT standards, and costs reflect the territory's affluent workforce.
Because Australian income tax is uniform, interstate career moves should be evaluated entirely on the following factors:
The 2% Medicare levy is the closest thing Australia has to a "variable" in the tax calculation — and it's still completely uniform. On A$80,000, that's A$1,600 per year, or A$133 per month. It funds Medicare, Australia's universal healthcare system. High-income earners without private hospital insurance pay an additional Medicare Levy Surcharge (MLS) of 1–1.5%, but the MLS threshold for singles in 2024–25 is A$93,000, so it does not apply on this study salary.
A useful comparison: American workers on a similar salary pay FICA taxes (Social Security 6.2% + Medicare 1.45% = 7.65%) totalling approximately US$5,738 on US$75,000 — purely for federal social programs. Australia's 2% Medicare levy on A$80,000 is A$1,600. The Australian system funds significantly more comprehensive healthcare coverage at a fraction of the FICA cost.

No. Australia has no state-level income tax. All income tax is collected by the federal government through the Australian Taxation Office (ATO) using uniform national tax brackets. Whether you work in Sydney, Melbourne, Brisbane, Perth, Adelaide, Hobart, Darwin or Canberra, your income tax bill on the same salary is identical. This is a key structural difference from countries like the US, where state income tax can add thousands of dollars in variation.
On A$80,000 in the 2024–25 tax year, an Australian resident pays A$16,467 in federal income tax (0% on the first A$18,200; 19% on A$18,201–A$45,000; 32.5% on A$45,001–A$80,000). The Low Income Tax Offset (LITO) is fully phased out at this income level (A$0). Adding the Medicare levy of 2% (A$1,600) gives a total tax of A$18,067, leaving a take-home of A$61,933. The effective total tax rate is 22.6%.
The Medicare levy is a 2% charge on your taxable income, collected alongside income tax by the ATO. For a salary of A$80,000 it is A$1,600 per year. It funds Australia's public health system. A Medicare Levy Surcharge of an additional 1–1.5% applies to higher-income earners without private hospital cover, but the threshold for singles in 2024–25 is A$93,000, so it does not apply at A$80,000.
Under standard salary (not package) arrangements, employer super contributions of 11.5% are paid on top of your salary and do not reduce your take-home pay. On A$80,000, your employer pays A$9,200 in super separately, and you take home A$61,933. If your contract specifies salary inclusive of super (a 'total package' arrangement), divide the package by 1.115 to find your actual cash salary.
Even though after-tax pay is identical in all 8 states, the cost of goods, services and housing varies significantly. Sydney and the ACT have significantly higher rents and living costs than cities like Adelaide or Hobart. Cost of living estimates suggest the effective purchasing power gap between the most and least expensive states is equivalent to around A$10,000–A$17,000 per year on an A$80,000 salary.
