In a paradigm shift in the strategic environment in the Indo-Pacific, Australia issued updates to two pivotal planning documents this week—its National Defence Strategy 2026 and Integrated Investment Program 2026—while simultaneously promising a boost in defence spending aimed at increasing its stakes.
On that front, it is understood that policymakers in Wellington have taken note of the changes in Canberra’s overtones, and there will be both continuity and changes in Wellington’s strategic posture as it nears elections later this year.
To begin with, while releasing the document, Australian Defence Minister Richard Marles pledged that defence accounts would receive an additional A$14 billion (US$10 billion) over the next four years, and an extra A$53 billion over the coming decade.
Further, priorities for the Australian Defence Force (ADF) include a preference for undersea warfare, more lethal maritime capabilities, and expanded long-range strike capabilities, as outlined in the National Strategy document.
The ADF will also increasingly adopt autonomous and uncrewed systems, as well as systems to counter those of adversaries.
Meanwhile, acquisition priorities for Canberra include a more resilient multi-orbit satellite communications network, as well as integrated air and missile defence systems.
The National Defence document recognises that Australia has serious air defence deficiencies. Further, Australia’s 2026 National Defence Strategy has confirmed plans to invest $7.8 to $11 billion over the decade to sustain and update the Royal Australian Navy’s Collins Class submarine fleet into the 2040s. This means Canberra will give equal preference to its conventional and nuclear submarines in the near future, which is a game-changer in its strategic posturing.
On this note, the conventional submarine component involves the expansion of the Collins Class submarine fleet, while the nuclear submarine component includes collaboration with the United States and the United Kingdom as part of the AUKUS deal.
Further, the expansion of the Collins Class submarine fleet includes ongoing sustainment, full-cycle docking for deep maintenance and upgrades, as well as a skilled workforce and infrastructure at Osborne Naval Shipyard in South Australia and at the Henderson Defence Precinct in Western Australia, according to information released under the Australian government’s multibillion-dollar 2026 National Defence Strategy and a revamped Integrated Investment Program.
It is understood that $94–$130 billion will be allocated over the decade to deliver undersea warfare capabilities. This includes ongoing investments to acquire conventionally armed, nuclear-powered submarines under AUKUS, sustain and extend the life of the Navy’s Collins Class submarine fleet, and continue to rapidly acquire uncrewed and undersea warfare support systems.
Australia’s transition to conventionally armed, nuclear-powered submarines is underpinned by the ongoing availability of the Collins Class submarine fleet, as per the documents. Further, the government is investing $7.8–$11 billion over the decade to ensure the Navy’s Collins Class submarines remain a potent strike and deterrent capability.
Meanwhile, Canberra will allocate 41% of funds to maritime capabilities, 22% to enterprise and enabling sectors (including infrastructure and information technology), 17% to land, 14% to air, 5% to cyber, and 2% to space.
Also, Canberra would have to nudge the United States into expanding its cooperative maritime enforcement agreements while helping to facilitate already signed agreements between the US and Pacific Island nations such as Kiribati, Palau, Tonga, the Marshall Islands, and the Cook Islands. These agreements allow local law enforcement officers to ride with US Coast Guard vessels to conduct law enforcement missions in their waters.
With China positioning itself to exert greater influence over the region, Australia will lose out if it does not properly come to terms with the sensitivities of its neighbourhood. Countries such as Fiji, the Solomon Islands, and Papua New Guinea are in the midst of political crises and, for now, the people of these small island states continue to look to Australia for assistance.
If Canberra is not able to offer these nations the reassurance they need, they may find themselves looking elsewhere, and China could end up matching its post-Cold War influence in Africa within Australia’s backyard—much to the discomfort of both Canberra and Wellington.
Meanwhile, it is understood that as the United States remains preoccupied with Middle East issues, China is expanding its strategic reach in the Indo-Pacific, with an increase in the range and scope of its submarine operations. In this context, Australia and India will work together on a collaborative research project aimed at enhancing undersea surveillance capabilities, marking the first science and technology pact between the two nations in this domain.
On the other hand, the National Defence Strategy document emphasises improving submarine detection and autonomous underwater vehicle tracking through advanced technologies, which are predominantly aimed at monitoring Chinese activities in the Indo-Pacific.
Meanwhile, last year, an initial scoping study of Australia–India bilateral cooperation was proposed for undersea intentions and capabilities; anti-submarine warfare (ASW); uncrewed underwater vehicles (UUVs); undersea search and rescue; and deep-sea awareness.
The three-year research programme envisages the deployment of an array of hydrophones behind submarines or surface ships to enhance acoustic monitoring. This innovation emerges amid a broader strategic effort within the QUAD—comprising India, Australia, Japan, and the United States—to deepen cooperation on maritime and transnational security, including the development of critical technologies. The National Defence Strategy document of Australia is the icing on the cake for these developments.
In conclusion, Canberra, despite the challenges posed by its nuclear submarine projects, will focus on undersea cooperation and anti-submarine warfare as part of its proposed plans.
