Average incomes vary across Australian states and territories, reflecting differences in industry composition, skill levels, cost of living, and economic activity. Western Australia consistently records among the highest average incomes due to the concentration of high-paying resources and mining sector employment.
The Australian Capital Territory records the highest median incomes of any jurisdiction, reflecting the concentration of federal public service employment which offers above-average salaries and job security.
ATO Taxation Statistics provide state-level income data from individual tax returns, allowing comparison of taxable income distributions across jurisdictions. ABS Employee Earnings statistics complement this data with more detailed occupational breakdowns.
Interstate income differences partly reflect different costs of living and housing costs. While Sydney and Melbourne incomes are higher in nominal terms, the higher cost of housing means disposable income after housing costs may be less favourable than in lower-cost states.
