Moving the Australia-India Maritime Partnership Forward Through Coast Guard Cooperation

Why It Matters

Enhanced coast guard collaboration will fill critical gaps in maritime security, deterring coercive activities and protecting trade routes vital to both economies. It also signals a rules‑based approach that can reassure smaller Indo‑Pacific states amid rising great‑power competition.

Key Takeaways

• Australia-India CSP includes civil maritime cooperation commitment
• Coast guard joint exercises remain ad‑hoc, need institutionalization
• Chinese grey‑zone tactics drive urgency for law‑enforcement collaboration
• Quad‑at‑Sea mission showcases multilateral coast guard interoperability
• Resource constraints limit expansion of bilateral coast guard capabilities

Pulse Analysis

The 2020 comprehensive strategic partnership between Australia and India has delivered robust navy‑to‑navy collaboration, yet civil maritime cooperation lags behind. Both nations rely on their coast guards to monitor vast exclusive economic zones, enforce fisheries regulations, and respond to maritime incidents. Institutionalizing joint exercises would transform sporadic, issue‑based drills into a predictable framework, allowing shared tactics and interoperable communications. As the Indo‑Pacific faces increasingly complex security dynamics, a formalized coast guard partnership can fill the gap left by naval engagements alone.

Chinese grey‑zone activities—ranging from artificial island construction to the deployment of dual‑use vessels—have blurred the line between lawful presence and coercive behavior in the Indian Ocean. These tactics threaten freedom of navigation and create enforcement challenges that navies alone cannot resolve. The 2025 Quad‑at‑Sea Ship Observer Mission demonstrated how coast guard crews from Japan, Australia, India and the United States can share real‑time intelligence and harmonize response protocols. Scaling such multilateral initiatives will enhance regional maritime domain awareness and deter illicit activities before they escalate.

Despite the strategic rationale, Australia’s fragmented maritime security architecture and India’s limited expeditionary coast guard capacity pose practical hurdles. Coordinating multiple Australian agencies—Border Force, Maritime Border Command and the Defence Force—requires clear governance and dedicated funding, while the Indian Coast Guard must balance naval competition for resources. A joint interoperability framework, modeled on the Australian‑U.S. Coast Guard program, could provide a roadmap for regular training, shared logistics and joint patrols. By institutionalizing these mechanisms, the two countries can elevate their maritime partnership, counter hybrid threats, and reinforce a rules‑based Indo‑Pacific order.
