Australia is preparing a massive expansion of its military budget, with defence spending to lift by $53 billion over the next decade as the federal government responds to what it describes as intensifying global risks. The surge in funding is designed to modernize capabilities and ensure the nation can navigate an increasingly volatile security environment in the Indo-Pacific and beyond.
The injection includes an immediate priority of $14 billion in additional spending over the next four years. This financial pivot arrives as the federal government prepares to release the 2026 National Defence Strategy (NDS), a roadmap intended to align Australia’s military capabilities with the evolving strategic threats facing the continent.
Defence Minister Richard Marles has warned that the strategic landscape is deteriorating. In excerpts of a forthcoming speech, Marles stated that Australia faces its “most complex and threatening strategic circumstances since the end of World War II,” noting that international norms which previously limited the apply of military coercion are continuing to erode.

The Drive Toward 3 Per Cent of GDP
A central pillar of the new strategy is the effort to increase defence spending as a percentage of the national economy. The government claims the new funding will bring Australian defence spending to roughly 3 per cent of GDP by 2033. However, this figure relies on NATO’s methodology for measuring expenditure, which includes “defence-adjacent” costs such as military pensions, housing subsidies for personnel and funding in other portfolios.
Under traditional measurement, Australian spending has typically hovered around 2 per cent of GDP and was forecast to reach 2.33 per cent by 2033. By switching to the NATO standard, the government can report a current spending level of 2.8 per cent, climbing to 3 per cent over the next decade.
This shift in accounting and spending comes amid significant diplomatic pressure from the United States. During a meeting in Singapore last year, US Defense Secretary Pete Hegseth informed Minister Marles that the US wanted to see Australia’s spending rise to 3.5 per cent of GDP, mirroring pressures placed on other NATO allies to bolster their deterrence capabilities.
Strategic Priorities: Submarines, Drones, and Shipyards
The $53 billion increase is not a single lump sum but a series of targeted investments aimed at high-end warfare and sovereign industrial capacity. A significant portion of the funding is already earmarked for critical infrastructure and emerging technology.
- Maritime Infrastructure: $12 billion is allocated to the upgrade of the Henderson shipyards in Western Australia. This facility is essential for the AUKUS partnership, serving as a hub to dock and maintain nuclear-powered submarines and construct future Mogami-class frigates.
- Autonomous Warfare: Between $2 billion and $5 billion is being directed toward new investments in drone technology, reflecting lessons learned from the war in Ukraine and conflicts in the Middle East.
- Long-term Scaling: The spending is heavily weighted toward the end of the decade, with $8.7 billion projected for 2033-34 and $9.8 billion for 2034-35.
Funding the Gap: ‘Alternative Financing’ and Cuts
As not all of this spending will appear in the traditional budget, the government is pursuing a mix of “alternative financing” and asset liquidation. This includes the planned sale of high-value defence real estate and the potential for the government to take equity stakes in private companies or invest through government-business enterprises.
However, the increase in spending is also accompanied by “reprioritisations”—a term often used to describe the scaling back or cancellation of existing projects. Minister Marles has acknowledged that these decisions are “not easy” but necessary to free up resources for higher-priority capabilities.
This approach has historically been a point of political friction. Three years ago, the government significantly rolled back two major army projects, slashing the planned acquisition of infantry fighting vehicles and reducing orders for self-propelled Howitzers. The Coalition has previously argued that cutting capabilities in one area to fund another creates dangerous gaps in national security.
| Period/Project | Estimated Funding |
|---|---|
| Next 4 Years (Immediate Lift) | $14 Billion |
| Henderson Shipyard Upgrades | $12 Billion |
| Drone Technology Investment | $2 – $5 Billion |
| 2033-34 Fiscal Year | $8.7 Billion |
| 2034-35 Fiscal Year | $9.8 Billion |
What This Means for National Security
The 2026 National Defence Strategy represents a pivot toward a “war-fighting” posture, moving away from the smaller-scale stabilization missions of the last two decades. The influence of the conflict in Ukraine and escalating tensions in the Middle East have convinced policymakers that the era of relative peace in the Indo-Pacific is being replaced by an “unprecedented military build-up.”
By focusing on nuclear submarines, autonomous systems, and a 3 per cent GDP spending target, the Albanese Government is attempting to signal both to its allies and to strategic competitors that Australia is prepared for a more contested regional environment.
The next critical checkpoint for these plans will be the formal release of the 2026 National Defence Strategy and the subsequent federal budget handed down next month, which will provide the first granular gaze at which projects are being axed to fund this $53 billion expansion.
