Australia’s defense spending this year is set to include infrastructure projects at five military bases in the Philippines.
The bases are all located on the island of Luzon, in proximity to the contested South China Sea and self-governing Taiwan – two major flashpoints in regional relations.
the investments come as Australia and the South-East Asian nation are expected to sign a new pact to increase collaboration between their defence forces.
Experts say these agreements are clears signs of how importent an ally the Philippines is becoming in the Indo-Pacific region.
Euan Graham, a senior analyst on defence strategy and national security at the Australian Strategic Policy Institute, said both nations were aiming to strengthen regional deterrence at a time when China was pursuing increasingly aggressive activities in the South China Sea and US foreign policy in the region was shifting.
He said Australia had become Manila’s “closest security relationship” after the United States and the political window for cooperation was “wide open” under Philippine President Ferdinand marcos Jr.
“President Marcos has made clear that he wants to have multiple security partnerships, not just to rely on the United States,” Dr Graham said.
“Australia and the Philippines are vrey broadly aligned in foreign policy – you could even make the case that they’re more broadly aligned than Canberra and Washington under the current Trump management.
“Australia wants to move now while there is a conducive political climate in the Philippines and also while the strategic situation continues to worsen.“

Defence Minister Richard Marles in August committed Australia to the “construction, use, upgrade, and maintenance” of eight defence infrastructure sites at five locations in the Philippines after Australia played a big role in Exercise Alon - a multilateral military exercise in the Philippines.
A joint statement issued by Mr Marles and his Filipino counterpart committed to “deepening defence cooperation” amid an “unprecedented military build-up taking place in the Indo-Pacific”.

A Defence spokesperson confirmed to the ABC the goverment had ”identified opportunities to develop military facilities at five locations” on Luzon.
The island is the largest and most populated in the north of the country on the contested West Philippine Sea and Taiwan strait.

The United States is planning to invest tens of millions of dollars in new infrastructure at four military bases in the Philippines, as both countries seek to deepen their security ties in the face of growing Chinese assertiveness.
The investments will be made at locations agreed under the Enhanced Defence Cooperation Agreement (EDCA), a 2014 pact that allows US troops to be stationed in the Philippines for joint military exercises.
The four additional sites will add to the five previously agreed locations,bringing the total number of EDCA bases to nine.
While the exact details of the investments are yet to be finalised, US officials say they will focus on improving facilities used for maritime security, counter-terrorism and humanitarian assistance.
“These new EDCA sites will allow us to respond more quickly to crises and to work more closely with our Philippine allies,” US Defence Secretary Lloyd Austin said in a statement.
The move comes as tensions rise in the South China Sea, where China has been increasingly assertive in its territorial claims.
The Philippines has been a vocal critic of China’s actions in the region, and has sought to strengthen its security ties with the United states in response.
China has accused the United States of using the EDCA agreement to encircle it and to interfere in regional affairs.
“We urge the United States to respect the sovereignty and security interests of regional countries and to do more to promote regional peace and stability,” Chinese Foreign ministry spokesman Wang Wenbin said.
the new EDCA sites are located in strategic areas of the Philippines, including near the South china Sea and Taiwan.
One of the sites is located in Palawan province,which is close to the Spratly Islands,a disputed territory claimed by China,the Philippines,Vietnam and other countries.
Another site is located in Cagayan province, which faces Taiwan.
The investments are expected to be welcomed by the Philippines, which has been seeking increased US assistance to modernise its military.
“This is a positive development for our defence cooperation with the United States,” said Philippine Defence Secretary Carlito Galvez.
“It will help us to enhance our capabilities to protect our country and to promote regional peace and stability.”
Becca Wasser, a senior fellow at the Center for a New American Security think tank, said the investments were a logical step in strengthening the US-Philippines alliance.
“The Philippines is a key ally for the United States in the indo-Pacific region, and it is important that we continue to invest in our relationship,” she said.
“The EDCA agreement provides a valuable framework for deepening our defence cooperation, and the new investments will help to ensure that we are able to respond effectively to any challenges that may arise.”
ms Wasser said it would make sense for Australia’s projects to be coordinated with the EDCA sites.
“The key investments will be things that help them [the Philippines] to secure their airways and their ports that will allow them to operate effectively and maintain security at those sites,” she said.
“It would be incredibly difficult for a country to try to invade and take over parts of the Philippines and so it doesn’t actually require that much investment.”
Rear Admiral Rommel Jude Ong, a retired vice commander of the Philippines Navy, said the new projects would likely focus on facilities that were used to house personnel and equipment for future military training exercises.
“If it is for the army, top of my list would be Fort Magsaysay in central Luzon, which is extensively used for army exercises,”
Rommel Jude ong’s Call for Diversified Philippine Alliances
Rear Admiral Rommel Jude Ong, former vice commander of the Philippine Navy, has advocated for the Philippines to broaden its security partnerships beyond the united States. He believes a more diverse alliance network, including countries like Japan and Australia, is crucial given evolving geopolitical dynamics and perceived shifts in US strategy.
Philippines-United States Alliance
The Philippines and the United States share a long-standing mutual defence treaty, formalized in the 1951 US-Philippines mutual Defense Treaty. this treaty commits both nations to defend each other in case of an armed attack. However,Ong suggests the future of Philippine security shouldn’t rely solely on this alliance. The Enhanced Cooperation Initiative (ECI), renewed in 2024, allows the US access to additional Philippine military bases, a point likely influencing Ong’s assessment of the US strategic trajectory.
Expanding Partnerships with Japan
Ong specifically highlighted Japan as a key potential partner. Japan and the Philippines have been strengthening their defense cooperation in recent years, including through reciprocal access agreements and joint exercises. In January 2024, the two countries signed a security pact to facilitate closer collaboration on defense and security matters. This aligns with japan’s increasing role in regional security, as outlined in its National Defense Strategy.
Australia as a Strategic Ally
Australia is also identified by ong as a valuable partner. Australia and the Philippines have a strong bilateral relationship, including defense cooperation.Australia has been actively involved in maritime security capacity building in the region, and increased defense cooperation was announced in late 2023. Australia’s commitment to regional stability, as detailed in its Indo-Pacific Strategy, makes it a natural partner for the Philippines.
Geopolitical Convergence and Future Challenges
Ong believes the geopolitical interests of the Philippines, Japan, and Australia are converging, particularly concerning shared challenges in the South China Sea. the Philippines, Japan, and australia all have concerns regarding China’s assertive actions in the South China Sea. Diversifying alliances allows the Philippines to address these challenges more effectively and reduce reliance on a single partner.

There have been no breaking developments contradicting Ong’s statements or the ongoing strengthening of ties between the Philippines, Japan, and australia.
