Two recent foreign challenges suggest that Australia needs urgently to increase its level of defence self-reliance and to ensure that the increased funding that this would require is available.
First, the circumnavigation of our continent by three Chinese warships in February and March puts in question our capacity to keep even one flotilla under persistent surveillance. To remedy this, we need to re-examine our intelligence and surveillance capabilities. We knew well enough where the Chinese warships were but not what they were doing.
Second, the aggressive behaviour towards Ukraine’s President Zelenskyy by President Donald Trump in the White House on 28 February raises the question of our need for a higher degree of defence self-reliance. This does not mean abandoning or jettisoning the alliance with the US. But it does mean we need better ability to manage military contingencies in our strategic approaches without depending on the United States.
This will demand greater capabilities in longer-range weapons and supporting capabilities for intelligence, surveillance and tracking. These contingencies raise the need for a significantly greater degree of defence self-reliance. The US under Trump will expect us to manage them by ourselves.
Further, the principle of extended deterrence in the Asia-Pacific—under which the US remains the strategic guarantor for its allies in the region, especially against nuclear attack—has not (yet) been challenged by Trump or his administration officials. That guarantee seems a curious exception to Trump’s transactional approach to other security commitments.
However, short of nuclear war, we need to ascertain whether our strongest ally has transformed overnight into our most immediate problem. Already we see that Russia’s long-standing ambition to divide NATO is several steps closer.
The assumption still reigns in Australia that military threats are something that happen to other people a long way away and will never come to our homeland. With that belief, we have indulged ourselves in the luxury of merely incremental increases in defence budgets, rather than the transformative investment that is now needed.
Such transformation is now needed to ensure, first, that the Australian Defence Force can surge to meet the demands of new, short-warning contingencies and sustain the associated higher rates of effort and, second, that the ADF can continue to be the basis for further military expansion in the event that our strategic circumstances deteriorate further.
Underlying these concerns is the need to understand that the US is undergoing radical change under Trump. As Sir Lawrence Freedman observes, ‘The US is shrinking before our eyes as a serious and competent power.’
Taken together, the observations set out above reinforce Australia’s need for a greater level of self-reliance. These new issues are demanding because of their severe and sudden impact on our strategic environment. They require Defence to revisit its allocation of resources.
Defence must review operational requirements for anti-ship missiles, drones and associated ammunition, sea mines, uncrewed submarines, air-to-air missiles and strike missiles. The review must result in a new allocation of resources to such systems.
In the past few years, it has become quite trendy for defence experts in Australia to assert we need to spend 3 to 4 percent of GDP on defence, compared with barely 2 percent now. That would mean finding an additional $28 billion to $55 billion a year and bringing the overall defence budget to between $83 billion and $110 billion a year, compared with $55 billion now.
On 7 March, the nominated US under secretary of defence, Elbridge Colby, bluntly called for Australia to spend 3 percent of GDP on defence.
Making such arbitrary claims for an additional $28 billion a year is not a responsible approach to defence planning. Instead, what is needed is a much finer-grained definition of the ADF’s needs for such materiel as mentioned above, particularly for long-range missile strike capabilities and their associated deterrence through denial. Australia’s Defence organisation now needs to get on with this as a matter of urgency.
Our focus now needs to be not so much on additional, hugely expensive major platforms, such as ships and crewed aircraft, but giving new priority to surveillance and targeting capabilities, missiles and ammunition and uncrewed systems. Such an approach would be much less expensive, and much more timely.
The fact remains that today’s ADF, together with supporting capabilities, has little ability to sustain operations beyond low-level contingencies. Moreover, assumptions about force expansion made over many previous decades are no longer appropriate, particularly with respect to major platforms. In contrast, a way forward is presented by the government’s 2024 Guided Weapons and Explosive Ordnance (GWEO) plan, which is aimed at establishing domestic supply of advanced munitions. It can significantly increase the ADF’s ability to sustain high-technology operations and credibly support powerful force expansion based on modern long-range precision strike and targeting. Again, this is much quicker and cheaper than buying yet more large and costly platforms.
Despite rising strike ranges, geography is not dead. As the 2024 GWEO plan says, ‘With vast maritime borders and critical northern approaches, Australia must be able to defend against any adversary who may project power close to our territory.’
At present, Defence is spending $28 billion to $35 billion to develop and enhance targeting and long-range strike capabilities out to 2034. These will give the ADF a greater capacity to hold at risk a potential adversary’s forces that could target Australia’s interests during a conflict. But this is just the beginning. There are more expensive investments to be made—for example, in integrated air and missile defence.
Merely asserting that a particular percentage of GDP is appropriate for the defence budget is not adequate. Arguments that say only ‘more is better’ will get us nowhere. Defence needs a story to tell—a conceptual framework, agreed and accepted by the government and by the machinery of government—as the basis for considering more specific issues and initiatives. It must be suitable for public presentation, not just to get public understanding of the need for increased funding but potentially to get acceptance of the need to handle what looks like an extremely worrying emerging strategic situation in the shorter term.
The issues to be confronted include the level of strategic risk that the government is prepared to accept. What options in this respect does it want to consider? How much further down the path of self-reliance and sovereignty does it want to go in this new strategic environment? What would be the right level of reliance on the Trump government for intelligence, operational and combat support and logistics support? What range of options (and at what cost) should Australia now develop for contributing to US-led operations in the Indo-Pacific? This consideration will need to address a wider choice than in the Cold War, when Australia’s need to support the US in the Western Pacific, and US expectations of support, were much lower.
Further, Australia needs to consider its options for working more closely with other countries in the region, such as Japan, especially in the event that the US reduces its commitment to the area.
In many ways, the key point is how best to position Australia’s national defence effort (not just the ADF) to be able to surge in response to short-warning contingencies involving China as a potential adversary and, in a different way, the US, presumably as an ally.
The short-warning contingencies of today’s strategic circumstances will be potentially much more demanding than those of earlier years.
The legacy of five decades of assuming extended warning time is, in effect, an ADF with little capacity today for sustained operations, especially at an intense level. So, positioning Defence to have this surge capacity requires close attention.
It is good that governments have, progressively, recognised most of these issues. But implementation has been slow. The end of the era of extended warning was made clear in the 2016 Defence White Paper, drafted in 2015. This was 10 years ago, the length of time during which previous defence policies assumed we would respond to strategic deterioration and expand the ADF. But in terms of more potent defence capabilities, we have very little to show for it.
Even so, Defence’s adoption of net assessments (modelling likely enemy capabilities against ours, including both sides’ logistics support) is a powerful tool contributing to decisions about the force structure, preparedness, and strategic risk. Decisions on communications, surveillance and targeting capabilities reflect the importance of Australian sovereignty in these vital areas.
Defence is grasping the opportunities presented by the new technologies of remotely operated uncrewed platforms (combat aircraft, small submarines and surface ships). Such platforms offer a more expeditious and less expensive mode of force expansion than the acquisition of major crewed platforms, just as local manufacturing of modern long-range precision strike missiles does.
The matters set out above would contribute to the basis for estimating the costs of defence policies, including the costs of different policy options such as different levels of self-reliance and strategic risk, more or fewer options for contributing to US-led Indo-Pacific operations, greater or lesser reliance on the US for sustainability stocks of spare parts and munitions during contingencies.
Other factors include the need to address workforce issues, including the difficulties that the ADF has in attracting and retaining its personnel. If the latter difficulties persist, there may well be a need to consider radically different approaches to the ADF workforce, including some form of national service, an increased focus on the Reserves, or both.
Arguments for increased funding based on the above analysis would be much more likely to carry the day than mere assertions that a particular arbitrary fraction of GDP should be the target for the Defence budget.
Finally, the authors of this article are of the view that Defence’s decision-making abilities are not adequate, even for peacetime governance. It is, therefore, but a short step to be concerned that the arrangements for decision-making in the event of the more serious contingencies that have now to be part of the defence planning basis would be even less adequate. This also needs attention.
