Ukraine and Australia signed a 10-year bilateral security agreement on Sept. 23 in New York, outlining long-term cooperation on defense, humanitarian assistance, energy security, cyber defense, economic recovery and accountability for Russia’s invasion.

The agreement reaffirms Australia’s support for Ukraine’s sovereignty and right to self-defense under international law. Australia said it would continue providing security assistance, military training and capacity-building, while exploring cooperation on air defense, missiles, drones and other defense technologies. The countries also agreed to examine opportunities for joint defense-industry projects and expanded information sharing.

The pact includes commitments to support Ukraine’s energy infrastructure, nuclear safety, humanitarian needs and postwar reconstruction. Australia will also work with Ukraine on cyber resilience, mine action, maritime security, sanctions enforcement and efforts to counter foreign information manipulation.

The agreement provides for high-level consultations within 24 hours in the event of a future armed attack on Ukraine after current hostilities have ended. It was signed by Ukrainian President Volodymyr Zelenskyy and Australian Prime Minister Anthony Albanese and will take effect upon signature, subject to the agreement’s stated conditions.
