Migrations from Southeast Asia.

Following the Maritime Highway Beyond Southeast Asia

Evidence, Possibility and the Limits of What We Know

“The sea does not draw lines on a map. Historians do.”

Indian traders clearly reached Southeast Asia. Indian ideas clearly shaped Cambodia, Java, Bali, Thailand and Myanmar. Austronesian navigators clearly crossed immense ocean distances, spreading from Taiwan and Island Southeast Asia across the Pacific and even westward to Madagascar. These Indian traders had both the motivation and the capabilities to explore far beyond Southeast Asia. The question I now want to examine is whether these overlapping maritime worlds carried Indian people, goods or ideas even farther south—to Australia, and perhaps eventually towards New Zealand.

The initial driver for eastward expansion from India was the search for gold, with traders targeting the most accessible deposits first. However, as gold supplies dwindled, Indian and Southeast Asian explorers were likely motivated to venture farther east and possibly south in search of new resources. For me, this raises an important question. If merchants had already crossed the Bay of Bengal, moved through the Straits of Malacca and entered the vast island world of Southeast Asia, why should we automatically assume that their exploration stopped there?

For Australia, contact is plausible. Northern Australia lies close to Indonesia, and later documented Makasar trading contact proves that regular voyages from Southeast Asia to Australia were possible. Some genetic research has also suggested gene flow from India into Aboriginal Australian populations around 4,230 years ago. Yet I believe this evidence must be treated carefully. Genetic influence does not prove that Indian merchants landed directly in Australia. It could reflect movement through intermediary populations, especially through Island Southeast Asia. The evidence suggests connection, not necessarily direct trade.

Migrations from Southeast Asia

The question of New Zealand is considerably more difficult. Did Indian ships sail directly to New Zealand? I believe the more likely scenario is to ask whether Indian-linked people, objects, plants, technologies or ideas could have moved gradually through Southeast Asian and Austronesian maritime networks. This is a fundamentally different proposition from imagining Indian merchant vessels sailing directly from the subcontinent to New Zealand.

The first issue is Indian maritime capability. Could Indian sailors undertake long-distance ocean voyages? The answer is clearly yes. For more than two thousand years, Indian merchants sailed across the Arabian Sea, the Bay of Bengal and into Southeast Asia. They used the monsoon winds, built ocean-going vessels, maintained merchant guilds and established permanent trading communities overseas. The question, therefore, is not whether Indian sailors possessed maritime capability. They clearly did. The question is how far their commercial interests and interconnected networks eventually carried them.

One plausible pathway towards Australia is:

India → Sri Lanka → Bay of Bengal → Malay Peninsula → Sumatra/Java → eastern Indonesia → Timor → northern Australia

This route follows known trading zones, island chains and shorter sea passages. Rather than requiring a single extraordinary voyage across an immense unknown ocean, it represents a gradual movement through an established maritime world. Each stage could connect with the next, allowing people, goods and knowledge to travel progressively farther from India.

This leads to what I consider the central issue: did India’s maritime world overlap with Southeast Asian networks that extended farther south? Southeast Asia is the key bridge. It was not merely the receiving end of Indian influence. It was an active maritime world in its own right.

Malay, Javanese, Sumatran, Bugis, Makasar and other seafaring peoples built trading networks across thousands of kilometres. They were not passive recipients of Indian culture. They were skilled navigators, traders and cultural intermediaries. Once Indian goods and people entered Southeast Asian ports, they could move onward without Indian sailors personally carrying them.

This distinction is critical. Historical influence does not require a person or object to travel directly from its original point of departure to its final destination. A trader from India might carry goods to Java. A Javanese merchant might then move them farther east. Another maritime community could transport them south towards Timor or northern Australia. Over generations, people, technologies, plants, beliefs and objects could move through multiple interconnected societies.

The strongest evidence that such long-distance movement was possible comes from the Austronesian world. Austronesian-speaking peoples achieved one of the greatest maritime expansions in human history. From Island Southeast Asia, they moved across Melanesia, Micronesia and Polynesia. They reached remote islands scattered across the Pacific. They also sailed west across the Indian Ocean to Madagascar.

Southeast Asia is a vast maritime world of thousands of islands. Around 2,000 years ago, its people depended on the sea for food, trade, and transport, developing exceptional ocean-going navigation and seafaring skills. Their maritime expertise made them well suited to serve as crew on long-distance exploratory voyages, including journeys into the waters south of the Indonesian archipelago.

This extraordinary expansion demonstrates that the maritime world connecting Southeast Asia with the wider oceans was not geographically confined. The same broad human world that interacted with Indian merchants also contained navigators capable of crossing some of the greatest ocean distances on Earth.

For me, this is where the conventional historical map becomes too restrictive. India, Southeast Asia, Australia and the Pacific are usually studied separately. Indian Ocean history belongs to one field. Southeast Asian history belongs to another. Australian history is often treated as an entirely separate story, while Pacific history occupies yet another academic category.

Yet the people who sailed these seas did not think in modern academic categories.

They followed winds, currents, islands, trade opportunities and inherited navigational knowledge.

This does not prove that Indian traders reached Australia directly, and it certainly does not prove that Indian ships reached New Zealand. The evidence must not be stretched beyond what it can support. For Australia, the possibility of contact is more plausible because of geographical proximity to Indonesia, the later documented Makasar voyages and genetic evidence suggesting some form of ancient connection with India. Even here, however, direct Indian contact remains unproven.

For New Zealand, the evidential gap is much greater. A direct voyage by Indian merchant ships would require far stronger evidence than is currently available. The more plausible question is whether Indian-linked people, objects, plants, technologies or ideas could have travelled indirectly through the vast maritime networks of Southeast Asia and the Austronesian world.

That possibility deserves serious consideration because maritime history rarely operates through simple straight lines. Goods change hands. Sailors join different crews. Communities intermarry. Technologies are copied. Plants are transported. Stories travel. Navigational knowledge accumulates. A connection between India and a distant region does not necessarily require a direct voyage between the two.

As I have followed the Golden Road eastward, this has become one of the most intriguing questions for me. We know Indian merchants reached Southeast Asia. We know Southeast Asian sailors possessed extensive maritime networks. We know Austronesian navigators crossed the Pacific and reached Madagascar in the opposite direction. We know later Makasar traders regularly sailed between Indonesia and northern Australia. We also have genetic research suggesting gene flow from India into Aboriginal Australian populations around 4,230 years ago.

Each piece of evidence must be assessed on its own merits. None proves that Indian traders sailed directly to New Zealand. None, by itself, proves direct Indian settlement in Australia. But together they challenge the assumption that the maritime worlds of India, Southeast Asia, Australia and the Pacific were completely isolated from one another.

The sea does not draw lines on a map.

Historians do.

For me, the most responsible conclusion is therefore neither certainty nor dismissal. The evidence for direct Indian contact with Australia remains incomplete but plausible enough to investigate. The evidence for direct Indian voyages to New Zealand is much weaker. Yet the possibility of indirect movement through Southeast Asian and Austronesian networks raises a broader question that should not be rejected simply because it falls between conventional historical disciplines.

Where the evidence is strong, I will present it as established history. Where it is incomplete, I will identify possibility as possibility. Where the argument becomes hypothesis, I will say so clearly.

But I believe the question remains worth asking.

If Indian merchants followed gold eastward, if Southeast Asian sailors carried goods and people across thousands of kilometres, and if Austronesian navigators crossed both the Pacific and Indian Oceans, how far south did these overlapping maritime worlds ultimately reach?
