Behind Australia's inflation debate: Spending, tax cuts and global shocks
As the Reserve Bank weighs another interest rate decision, political blame focuses on government spending, but economists point to tax cuts and global factors.

At a glance
- The Opposition frequently blames federal government spending for driving up inflation and forcing interest rate hikes.
- Structural deficits, driven by permanent tax cuts rather than spending alone, are the main fiscal culprit.
- Global oil price shocks and a massive private sector data centre construction boom have also fueled economic pressures.
As Reserve Bank Governor Michele Bullock prepares for her post-rate decision press conference, political debates in Canberra are once again focusing on who bears responsibility for stubborn inflation.
While the Opposition has consistently targeted federal Treasurer Jim Chalmers over government outlays, the narrative overlooking tax revenue cuts and global economic forces is deeply misleading.
The political blame game over spending
Shadow Treasurer Tim Wilson and the wider Opposition have repeatedly argued that excessive government spending is pushing up prices and forcing the Reserve Bank to increase interest rates. This messaging has resonated strongly with households facing high mortgage repayments and living costs.
However, economic analysis indicates that government spending on its own does not dictate inflation. Instead, budget deficits—the gap between tax revenue and government expenditure—inject net demand into the economy.
How tax cuts and revenue losses shaped the deficit
Australia has delivered budget surpluses in only two instances over the past twenty years. Successive governments have routinely used tax cuts to woo voters without offsetting them with spending reductions.
Decisions by past administrations, such as abolishing the mining tax under former prime minister Tony Abbott, cost the federal budget tens of billions of dollars over a decade. Combined with the removal of the carbon tax, these policy choices systematically eroded government revenue while maintaining or increasing public spending.
