Australia's economic growth falters as public spending pulls back

Australia's economy lost momentum in the opening months of 2025, with the latest national accounts confirming a deceleration that threatens to test the resilience of private spending as government investment retreats.

Gross domestic product expanded by just 0.4 per cent in the first three months of the year—down from 0.6 per cent in the previous quarter. The slowdown arrives at a pivotal moment for the economy, as large-scale infrastructure projects that have underpinned growth in recent years begin to wind down, shifting the burden of keeping the economy moving squarely onto the shoulders of private business.

The deterioration in growth rates, though still positive, reflects a fundamental shift in economic dynamics. Public investment, which has cushioned Australia through the post-pandemic recovery, is now declining. This withdrawal of government spending support was always expected as infrastructure programs reached completion, but the timing raises questions about whether the private sector is ready to shoulder the load.

Westpac senior economists have characterised the transition as a "shaky handover"—a phrase that cuts to the heart of current economic anxieties. Rather than a seamless shift of economic momentum from public to private spending, there is risk of disruption if businesses and consumers do not accelerate their spending and investment fast enough to offset the government's retreat.

Infrastructure spending has been a critical economic crutch for years. Major projects across roads, rail, ports and other infrastructure have provided steady demand for materials, labour and services. As these programs complete, that demand evaporates unless private sector confidence and investment rise to fill the gap. The quarterly accounts suggest that gap may not yet be closing.

Consumer spending, business investment and export performance will all need to strengthen if Australia is to avoid further deceleration. So far, there are few clear signals that such a pickup is underway. Rising interest rates, inflation concerns and household cost-of-living pressures have weighed on consumer confidence, while business investment remains cautious. Export volumes continue to be driven largely by commodity prices rather than expanding production.

The 0.4 per cent quarterly growth rate, while still expansion rather than contraction, sits at the lower end of trend. It underscores how much the economy is now dependent on the private sector performing well. Any continued faltering in business investment or consumer spending could tip the economy toward genuine weakness in the quarters ahead.

The Reserve Bank and government policymakers are now watching this transition intently. The outcome will shape both monetary policy decisions and the fiscal support that may be required in coming months. For now, the "shaky handover" is underway—and its success or failure will determine whether Australia's growth story continues or stalls.
