Prime Minister Anthony Albanese has declared a "watershed moment" in Australia's relationship with Indonesia as he travels to Jakarta to sign a landmark new security treaty with President Prabowo Subianto. The Prime Minister departed Canberra on Thursday afternoon for a significant three-day visit to Australia's closest major neighbour, accompanied by Foreign Affairs Minister Penny Wong.
A Historic Security Partnership Elevation
At the heart of this diplomatic mission is the Australia–Indonesia Treaty on Common Security, a comprehensive agreement designed to substantially elevate the security partnership between the two nations. The treaty aims to forge a stronger collaborative framework for mutual defence and regional stability, marking what officials describe as the most substantial advancement in bilateral relations in decades.
Mr Albanese emphasised the profound significance of this agreement, stating it represents a major extension of security and defence cooperation between Canberra and Jakarta. "This treaty is a watershed moment in the Australia–Indonesia relationship," the Prime Minister affirmed. "It demonstrates that our relationship is as strong as it has ever been, built on a foundation of shared interests and mutual respect."
Commitment to Regional Stability
In his remarks, Mr Albanese highlighted the unique and enduring bond between the two nations, describing them as neighbours, partners, and friends committed to a secure, stable, and prosperous Indo-Pacific region. He expressed gratitude to President Prabowo for the invitation to visit Indonesia for this historic signing ceremony and looked forward to discussions on further collaborative opportunities.
Foreign Minister Penny Wong echoed the Prime Minister's sentiments, characterising the treaty as "the most important step in strengthening our partnership in thirty years." Ms Wong noted that the agreement brings cooperation to a higher level, enabling both nations to act together more effectively to secure peace and stability for their citizens and the broader region.
"In these uncertain times, this treaty demonstrates the importance we place on our relationship and the respect we have for each other," Ms Wong stated. "This is precisely how the Albanese Government is building Australia's future within our regional context."
Context of Australia-Indonesia Relations
Australia and Indonesia have maintained generally stable diplomatic relations throughout Indonesia's eighty-year history as an independent nation, though this stability has occasionally been punctuated by moments of bilateral tension and crisis. President Prabowo Subianto, a former military chief who succeeded Joko Widodo after his presidential term limit expired in 2024, has visited Australia twice, including as recently as November last year.
Beyond security matters, the two nations collaborate extensively across multiple domains including trade and investment, education initiatives, and development programs. The Australian government has specifically identified Indonesia's robust economic growth as presenting significant opportunities for Australian investors and businesses seeking regional expansion.
Economic Dimensions of the Partnership
Indonesia, with its population of 287 million people, represents one of Southeast Asia's most dynamic economies. The nation recorded a year-on-year GDP growth of 5.04 percent in the third quarter of 2025, underscoring its economic vitality and potential for further development. This economic strength complements the strategic security partnership now being formalised through the new treaty.
The signing ceremony in Jakarta represents not just a diplomatic formality but a substantive commitment to deeper engagement between two of the Indo-Pacific's most significant nations. As Prime Minister Albanese and President Prabowo put pen to paper, they are cementing a relationship that both governments believe will contribute significantly to regional security architecture for years to come.
