Overview

Australia and India are two of the most significant democracies in the Indo-Pacific region, positioned at opposite ends of the Indian Ocean. Their partnership is grounded in historical bonds, democratic values, people-to-people ties, economic complementarity, and strategic alignment. Over time, this has evolved into a comprehensive strategic relationship vital for regional stability and global peace.

Remarkably, ancient Indian texts refer to Australia as shAlmali dwiipa. This name is still used today in traditional Vedic rituals called sankalpa, performed by Hindu Australians at the start of any religious ceremony. Vedic scholars trained in the purohita tradition, continue to use this name when administering these rituals in Australia.

Geological, Geographical and Biological Connections

Ancient Landmass: Gondwana

Australia and India were once part of the same landmass. Earth’s tectonic history tells us that both countries sit on the same tectonic plate, the Indo-Australian Plate, and were once part of Gondwana — a vast southern supercontinent that eventually separated into Australia, India, Africa, South America, and Antarctica. Sources: Wikipedia (Gondwana); Britannica (Gondwana Supercontinent); Otago Museum; UNSW Gondwana research.

Shared Biology: Marsupials and Seed Ferns

Biological evidence supports this shared origin. Both Australia and India once had marsupials (pouched mammals) and Glossopteris seed ferns. While marsupials thrive in Australia today, they were displaced in India when the subcontinent merged with the Eurasian landmass. A fossilised marsupial tooth has even been found in Gujarat, India. Similarly, the coal beds of both countries contain evidence of these ancient seed ferns, first identified in the Gond region of Central India — which is how Gondwana got its name.

The shAlmali Tree: A Living Link

The word shAlmali also refers to the Red Silk-Cotton tree, which is widely found in Northern Australia and Queensland. Its presence reinforces the ancient Indian identification of Australia as shAlmali dwiipa.

The Dingo: India’s Gift to Australia

The dingo (Canis dingo), Australia’s apex land predator, arrived approximately 4,000 years ago along with a wave of human migration from India. It feeds on everything from rabbits to kangaroos and remains a significant part of Australia’s ecology.

The Eucalyptus Story: Two Blue Mountains

Two mountain ranges — the Blue Mountains of South Australia and the niilgirii hills (नीलगिरी = Blue Mountains”) of South India — share the same name for very different reasons. The Australian range appears blue due to aromatic oils evaporating from Eucalyptus trees. The niilgirii hills in India were historically coloured blue by the blooming of the niilakurinji flower (Strobilanthes kunthiana), a species that flowers en-masse only once every 12 years.

During British colonial rule, Eucalyptus was transplanted from Australia to the niilgirii Hills in India to provide timber and firewood. The trees thrived — but at a cost. Their water-intensive growth threatened the native Neelakurinji. Restoration efforts are now underway to protect this ecologically and medicinally important native plant. The tree eventually spread across India and became known colloquially as “niilgirii” in many Indian languages. Source: Down to Earth (Eucalyptus and India’s grasslands).

Shared Geography and Climate Profiles

Both countries share comparable geographical profiles: deserts, mountains, plateaus, coastlines, forests, rivers, and vast rural and urban areas. The Tropic of Cancer passes through India in the Northern Hemisphere, while the Tropic of Capricorn traverses Australia in the Southern Hemisphere. Both nations are key stewards of the Indian Ocean.

Historical Human Movements and Civilisational Connections

Archaeological Evidence

The earliest humans are believed to have arrived in northern Australia more than 65,000 years ago, migrating from India through South-East Asia. Archaeological sites such as Willandra Lakes have revealed ancient burial and cremation practices — including the famous Mungo Lady and Mungo Man — reflecting sophisticated, enduring civilisations.

Source: Wikipedia (Prehistory of Australia).

Genetic Evidence

Genetic studies confirm that the ancestors of Indigenous Australians migrated out of the central landmass more than 60,000 years ago, following a southern coastal route through India. Some Indigenous Australians share ancient mitochondrial DNA markers (such as haplogroup M42) with Austroasiatic-speaking tribes in India. Sources: Smithsonian Magazine; PNAS (2013 genetic study).

The Genome India Project (2024–2026)

A landmark study sequenced the genomes of nearly 10,000 individuals across more than 80 Indian populations, identifying 44 million novel genetic variants not found in any other global database. Separately, large-scale 2025 studies show that Indians carry an unusually rich diversity of DNA from archaic humans such as Neanderthals and Denisovans.

rAkhigarhii and the Indus Valley Civilisation

Ancient DNA from a skeleton at rAkhigarhii, an Indus Valley site, contained no “Steppe” ancestry. Scholars such as Dr Vasant Shinde interpret this as evidence that the Harappan civilisation was entirely indigenous. Mainstream researchers generally conclude that Steppe migrations occurred after the decline of the Indus Valley Civilisation rather than contributing to its origins.

The 4,000-Year-Old Australian Connection

Around 4,230 years ago, there was a significant flow of people from India to Australia. Geneticists have found that some Indigenous Australians carry up to 11% Indian DNA. This migration is associated with the arrival of the dingo and new stone tool technologies (microliths) on the continent.

Linguistic Connections

There are notable similarities between Tamil and Dravidian languages, Austroasiatic languages (such as santhAli, Kol, and Khasi), Austronesian, and Australian Aboriginal languages. These may reflect ancient maritime contact, shared ancient substratum influences, or common ancestry. The name “Australia” derives from the Latin Australis, meaning “of the South.” Many Australian place names remain in their original Aboriginal forms, preserving thousands of years of linguistic heritage.

Folk Traditions and Shared Practices

Aboriginal Australian and Indian tribal traditions share certain features, including:

• Observance of totems and clan-based family lineages
• Prohibition of marriage within the same clan
• Cremation of the dead
• Knowledge systems in astronomy, navigation, agriculture, and forest management
• Reverence for nature and the divine

Ancient Vedic Texts and Civilisational Lore

Ancient Indian texts, including the vAlmIki rAmAyaNa, name the islands to the south and east of India. shAlmali dwiipa (Australia) is described as lying beyond yAva dwiipa (Java) and is identified as the abode of Garuda — a giant eagle. This connection is notable given that giant eagles once existed in Australia, and eagles feature prominently in Aboriginal Dreaming stories.

Rishi Agastya: The Ocean Master

Rishi Agastya, a revered sage of the Vedic tradition, is credited with laying the foundations of Tamil language and culture before travelling southward across the ocean. He is described in legend as a master of the seas — symbolised by the act of “drinking the ocean” — and is venerated across South-East Asia, Indonesia, Cambodia, and beyond. The star Canopus, the second-brightest star in the southern sky, is named Agastya in Indian tradition, marking his historical reach into the southern hemisphere.

The Yolngu and Makassan Connections

The Yolngu people of northern Australia maintained deep traditional connections with the Makassan people of Sulawesi, Indonesia, spanning not just centuries but millennia. These ties included trade, intermarriage, and strong cultural bonds. These connections were forcibly disrupted by colonial-era Australian governments. Today, the Yolngu people continue to seek restoration of these ties, affirming that the ocean between them is a connector, not a divider. In their folk tradition, Australia is known as Marawuwu — a name that may echo the ancient term Meru. Source: Monash University research project on Yolngu-Makassan connections.

The Human Bridge: Indian Diaspora in Australia

The most visible and dynamic connection today is the people. The Indian Australian community has built a strong and positive reputation through hard work, civic engagement, and contributions to Australia’s economy, healthcare, education, and cultural life.

As of 30 June 2025, the Indian-born population in Australia reached 971,020 — making it the largest overseas-born group, narrowly surpassing those born in England (970,950). This represents approximately 3.5% of Australia’s total population of 27.6 million. Notably, the share of Indian-origin Australians (3.5–4%) is more than double the share of Indian-origin Americans in the United States (approximately 1.5%). Source: Australian Bureau of Statistics, Population by Country of Birth (June 2025).

Sports and Cultural Bonds

Cricket has connected the two nations for generations. Bilateral Test and limited-overs series, despite occasional controversies, remain a powerful cultural link. Both countries share a deep passion for the game, and their cricketing rivalry is characterised by sporting spirit and mutual respect.

Cultural ties extend further through Buddhism, Hinduism, and the growing practice of Yoga. Devotional organisations such as ISKCON, BAPS, and HSS have established strong presences in Australia, further deepening these bonds.

Economic Ties: Trade, Investment and Skills

Bilateral trade has grown substantially. In FY2024–25, total merchandise trade reached approximately USD 24.1 billion. Two-way goods and services trade was valued at around AUD 54.4 billion in the same period. The Australia–India Economic Cooperation and Trade Agreement (ECTA), signed in 2022, has been central to this growth. Source: DFAT; IBEF; Koffels.com.au.

Recent Trade Figures (2026)
Australia’s exports to India (February 2026): approximately AUD 1.77 billion.
Australia’s imports from India (February 2026): approximately AUD 1.13 billion.
Australia maintains a consistent monthly trade surplus, with a merchandise balance of around AUD 1.08 billion.

Key Export and Import Categories

Australia exports primarily coal, coke, briquettes, gold, and agricultural products to India. India exports refined petroleum, pharmaceutical formulations, textiles, and precious stones to Australia. From 1 January 2026, 100% of Australian tariff lines became zero-duty for Indian exports under ECTA. The agreement has driven growth in Indian textile and gem exports while securing vital raw materials for Indian industry. Both sides benefit from this open and mutually reinforcing trade relationship.

Strategic and Geopolitical Partnership

In the contemporary era, Australia and India collaborate through the Quadrilateral Security Dialogue (QUAD), alongside Japan and the United States, in support of a free and open Indo-Pacific. They maintain a Comprehensive Strategic Partnership covering defence cooperation, logistics, maritime security, critical minerals, technology, and supply chains. In addition to being a part of trilateral partnerships with France and Indonesia, both countries are active members of a wide range of international and regional bodies, like:

• G20
• Commonwealth of Nations
• East Asia Summit (EAS)
• ASEAN Regional Forum (ARF)
• Indo-Pacific Oceans Initiative (IPOI)
• Indian Ocean Rim Association (IORA)
• Indian Ocean Naval Symposium (IONS)
• Indo-Pacific Economic Framework for Prosperity (IPEF)
• Indian Ocean Tuna Commission

Shared Challenges and the Need for Cooperation

Both democracies face hybrid challenges in the Indo-Pacific region. These include concerns about expansionist policies, maritime militarisation, economic coercion, and transnational terrorism. Robust bilateral and Quad cooperation — through shared intelligence, capacity-building, and democratic resilience — remains essential to addressing these threats.

The Path Forward

Australia and India exemplify how ancient civilisational threads, vibrant diaspora energy, democratic values, and shared strategic interests can forge a resilient and enduring partnership. As the Indian Australian community continues to grow and contribute, and as both governments deepen institutional ties, the relationship is well-positioned to strengthen further.

In a dynamic Indo-Pacific marked by geopolitical uncertainty, this people-to-people bridge across the Indian Ocean offers a model of constructive cooperation for peace, prosperity, and stability.
