Q. India's defence partnership with Australia has evolved from bilateral to multilateral engagement. Discuss with examples. (15 marks, 250-350 words)

India and Australia elevated ties to a Comprehensive Strategic Partnership in June 2020, with defence as a key pillar [1]. What began as episodic bilateral contact has since widened into institutionalised bilateral machinery and, increasingly, into plurilateral Indo-Pacific military engagement.

Bilateral foundations - The Mutual Logistics Support Arrangement (MLSA), 2020 gives reciprocal access to each other's bases for refuelling and replenishment — the enabler for long-range deployments [1]. - Institutional architecture has deepened: Defence Policy Talks, the 2+2 Ministerial Dialogue, and an annual India–Australia Defence Ministers' Dialogue established in 2025 [1]. - Exercise AUSTRAHIND, instituted in 2022, is an annual army exercise held alternately in each country; its fourth edition was conducted at Perth in October 2025 with a 120-strong Indian contingent [2].

Shift to multilateral engagement - Exercise Malabar: Australia's inclusion from 2020 converted a bilateral naval drill into a Quad-aligned four-nation exercise; Malabar 2025 at Guam saw INS Sahyadri operate with US, Japanese and Australian navies [3]. - Exercise Pitch Black: the IAF has participated in the RAAF's biennial multinational air combat exercise in 2018, 2022, 2024 and 2026. In Pitch Black 2026 at RAAF Base Darwin (20 July–7 August), India deployed Rafale fighters with C-17 and IL-78 support aircraft to validate expeditionary operations [4]. The 2024 edition involved 20 countries and over 140 aircraft [5]. - Such platforms deliver what bilateral drills cannot — interoperability with fifth-generation air forces, common communication protocols, and sustained operations across Indo-Pacific distances.

The trajectory is therefore complementary rather than substitutive: bilateral agreements supply the legal and logistical scaffolding, while multilateral exercises convert it into operational capability. Going forward, deepening defence-industrial collaboration and maritime domain awareness cooperation would give the partnership durability beyond exercises, anchoring India's Indo-Pacific Oceans Initiative vision of a free, open and rules-based regional order.
