Australia’s international spending reveals uneven ambition

How Australia funds development and defence was front of mind before Tuesday’s federal budget. US President Donald Trump’s demands for a dramatic lift in allied military spending and brutal cuts to US foreign assistance meant that a discussion was unavoidable. The difficult politics of increasing defence spending in Europe continues, and the British government has cut aid to pay for a rise in its defence budget.

This is an important discussion, but we ought to be considering investment in Australia’s strategic posture as a whole.

One way to measure that is the overall level of international spending. Taken together, defence, foreign affairs and trade, aid, the intelligence community and international policing total $72.05 billion for 2025–26, which is about 9 percent of total federal spending.

This share of spending has been steady at a little less than 10 percent since 1999. Attention has understandably focused on a potential lift in the defence budget. But we should think more broadly: there is a strong case that the overall level of spending on tools of ‘statecraft’ needs to rise above its steady level.

Within that $72.05 billion, defence dominates at $58.99 billion. There has been some reprofiling across the forward estimates, but this is consistent with the existing trajectory.

Time will tell whether the Trump administration decides to make an issue of this level of spending, which still hovers around 2 percent of GDP. Time will also tell whether Defence’s ambitious acquisitions program is achievable without further increases.

The official development assistance budget is $5.10 billion. This is about the same as the 2024–25 budget, adjusted for inflation. From a global perspective, with aid spending in retreat in many countries, this is welcome.

We should all recognise the particularities of Australia’s strategic circumstances. One such feature is a neighbourhood of low-income and middle-income countries. Development assistance in this context is not altruism but a strategic necessity. It helps offset risks that are born of underdevelopment, and that directly threaten Australian interests.

Moreover, experts across Southeast Asia have been clear on how Australia should respond to US aid cuts: ensuring stability in existing programs is the top priority.

The foreign affairs and trade budget is $3.91 billion. Within this, the diplomatic or foreign policy operating budget is $1.76 billion. This is a narrower measure, constructed by James Wise and originally published by ASPI. It strips out administered spending and other costs, such as IT and infrastructure, to provide a reasonable measure of Australia’s spending on diplomacy.

As Development Intelligence Lab research has previously noted, of Australia’s relevant budgets over the past 25 years, investment in diplomacy has been the most inconsistent. Although there has been no dramatic cut, projected inflation-adjusted declines in both the overall foreign affairs and narrower diplomatic budgets out to 2028 are concerning.

Australia’s intelligence community will receive a modest real budget rise to $2.05 billion year-to-year (this number excludes the Australian Signals Directorate, which is budgeted under Defence). This tallies with the recently released Smith-Maude Review, which recommends continued investment in Australia’s intelligence agencies, with focus areas including the Office of National Intelligence’s capability as a coordinating agency.

Finally, the Australian Federal Police budget (excluding domestic policing functions) is $2.00 billion, a small real decline compared to the 2024–25 budget. With the federal police now central to high-profile components of Australia’s engagement in Southeast Asia and the Pacific, such as the Pacific Policing Initiative, we can expect the federal police’s international spending to remain significant.

In short, defence spending has been bumped but its trajectory remains essentially the same. Aid, diplomacy, the intelligence community and federal policing are all at about a steady state, with modest inflation adjusted declines across the forward estimates.

The good news is that Australia has not decided to rob Peter to pay Paul. Nonetheless, the big questions remain: in 2025, do we really think that these tools should receive the same share of federal budget they received in 1999?

Things weren’t simple in 1999, and they’ve only become more complex since then. The crisis surrounding East Timor’s independence and then the 9/11 attacks in 2001 marked the beginning of complicated decades for Australian defence and foreign policy.

But Australia is now grappling with how to respond to a fraught position between China and the United States, while also trying to find a durable place among a crowd of ambitious partner nations across Southeast Asia and the Pacific. We need to properly invest in a broad range of tools to navigate this.
