Indonesia and Australia signed a new bilateral security treaty, on 6 February 2026, marking a significant step in strengthening defence and strategic cooperation between the two neighbouring countries. The agreement was formalised in Jakarta by Indonesian President Prabowo Subianto and Australian Prime Minister Anthony Albanese, reflecting a shared commitment to closer security coordination amid evolving regional dynamics.
The newly signed treaty provides a framework for regular consultations on security and defence matters at both political and ministerial levels. It also establishes mechanisms for dialogue and cooperation in response to potential threats or challenges that may affect either country. While the agreement does not constitute a formal military alliance or mutual defence obligation, it institutionalises security cooperation that has expanded steadily in recent years.
Prime Minister Albanese described the agreement as a watershed moment in Australia-Indonesia relations, characterising it as the most substantial advancement in bilateral security ties in decades. He noted that the treaty builds on earlier arrangements and reflects a growing level of trust between the two countries. Australian officials emphasised that the pact is designed to enhance transparency, and coordination in security engagement.
President Prabowo underscored that the treaty is consistent with Indonesia’s long-standing “free and active” foreign policy, which prioritises constructive relations with partners while maintaining strategic autonomy. He highlighted the importance of cooperation between Indonesia and Australia as close neighbours with shared interests in regional stability, emphasising dialogue and mutual respect as guiding principles of the agreement.
The signing of the treaty follows the conclusion of negotiations announced in late 2025 and builds on existing defence cooperation frameworks, including arrangements for joint exercises, defence education, and capacity-building initiatives. Both governments indicated that the agreement would further strengthen collaboration between their defence institutions and support continued engagement between armed forces.
Regional security considerations featured prominently in statements surrounding the signing. Leaders from both sides acknowledged the importance of maintaining peace and stability in the Indo-Pacific, particularly at a time of heightened geopolitical uncertainty. The treaty was presented as a confidence-building measure aimed at reinforcing cooperative approaches.
The agreement also carries symbolic significance, reflecting an improvement in bilateral relations. By formalising security dialogue at the highest levels, both Indonesia and Australia signalled their intention to anchor the relationship in long-term strategic cooperation.
Overall, the security pact represents a notable development in Indonesia-Australia relations, reinforcing their partnership through structured engagement and regular consultation.
