Australian Government Spending Rises Amid Growing Inflation and Cost of Living Pressures

Federal government spending has emerged at the center of political debate as inflation figures climb and pressure mounts on households. Opposition leader Angus Taylor questioned the prime minister during parliamentary question time on Wednesday, blaming government spending for rising costs for families and small businesses.

Economic Pressures

Official data released on the same day showed inflation jumped to 4.3 percent in the year to September, up from 4 percent the previous month. Rapid increases in petrol and diesel prices drove that headline number higher. Even after removing soaring fuel prices, underlying inflation ticked up to 3.7 percent by the quarterly measure. Both figures remain well above the Reserve Bank target of 2.5 percent, pointing toward an expected interest rate hike.

Spending Drivers

Total government expenses surged by 30 percent between the 2021-22 and 2025-26 periods, according to the parliamentary budget office. Federal spending grew by 5.5 percent in 2024-25 and 4.3 percent in 2025-26 after adjusting for inflation. Stephen Bartos, a University of Canberra professor and former finance department deputy secretary, identified three main drivers behind the increase: defense spending responding to global geopolitical tensions, the National Disability Insurance Scheme, and health sector costs including new hospital funding deals with states and a more generous pharmaceutical benefits scheme. Public expenditure as a share of the economy has reached its highest level since the early 1980s, excluding the pandemic era.

Budget and Expert Views

Stephen Smith, a partner at Deloitte Access Economics, noted that much of the recent spending increase is structural and would have occurred regardless of which political party held power. However, Smith emphasized the need for a tight fiscal strategy and difficult decisions. Budget papers show a deficit just under $10bn in 2024-25, $22.3bn in 2025-26, and an expected shortfall of $31.5bn this financial year.

Context

Government budgets balance incoming tax revenues against outgoing expenses to provide public services, infrastructure, and social support. When outlays outpace revenue, governments run a deficit, which injects demand into the economy and can influence broader macroeconomic conditions like inflation and interest rates.
