The ancestors of modern Aboriginal Australians migrated to the continent during the Stone Age, between 50,000 and 65,000 years ago. This migration occurred during the closing stages of the Pleistocene epoch, when sea levels were lower and Australia and New Guinea formed a single landmass known as Sahul. While the exact route taken by these early migrants is still debated by archaeologists, it is believed that they arrived by sea, using sophisticated watercraft and maritime skills to navigate across islands and deep, open seas.

Migration from Africa to Southeast Asia
The migration of Stone Age people from Africa to Southeast Asia is a complex and fascinating topic that has been extensively studied by archaeologists and geneticists. Here is a detailed overview of this ancient journey.
The First Migrants
The earliest migrations out of Africa were undertaken by archaic human species such as Homo erectus, also known as African Homo erectus or Homo ergaster. Fossil evidence suggests that Homo erectus expanded into southern Eurasia by 1.75 million years ago, with their presence in Southeast Asia established by at least 1.6 million years ago. Key sites indicating this early migration include Riwat in Pakistan, Ubeidiya in the Levant, and Dmanisi in the Caucasus.
The Southern Route
A significant migration event occurred when a small group from East Africa, bearing mitochondrial haplogroup L3, crossed the Red Sea to present-day Yemen around 75,000 years ago. Their descendants spread along the southern coastal route around Arabia and Persia to South Asia before 55,000 years ago. This migration is associated with mitochondrial haplogroups M and N, derivatives of L3. Along this journey, these early humans interbred with Neanderthals and Denisovans, with Denisovan DNA making up 0.2% of mainland Asian and Native American DNA.
Into Southeast Asia
The migration continued eastward along the Asian coast to Southeast Asia. Stone tools discovered in India, Yemen, and the United Arab Emirates, dating between 70,000 and 80,000 years ago, provide evidence of this journey. Genetic studies further support an early dispersal into Southeast Asia, with modern human bones found in a cave in Laos dated to between 68,000 and 86,000 years ago. These ancient migrants likely contributed to the peopling of Southeast Asia, which later diverged into various ancestral groups, including Ancient Ancestral South Indians (AASI), Andamanese, and East Asians.
Reaching Australia
The migration from Africa to Southeast Asia was a crucial step in the eventual peopling of Australia. The ancestors of modern Aboriginal Australians migrated by island-hopping and crossing land bridges from Southeast Asia to Australia. This journey occurred during the Pleistocene epoch when sea levels were lower, and Australia formed a single landmass with New Guinea, known as Sahul. The earliest evidence of human settlement in Australia is estimated to be between 60,000 and 65,000 years ago, marking a significant achievement in early human history.

Land bridges and sea crossings
The ancestors of modern Aboriginal Australians first migrated to the Australian continent between 50,000 and 65,000 years ago. This migration is believed to have happened via land bridges and short sea crossings from what is now Southeast Asia. During the Pleistocene epoch, repeated episodes of extended glaciation resulted in decreases in sea levels by more than 100 meters in Australasia. This created land bridges and reduced the distance between islands, allowing for island hopping.
At the time, Australia and New Guinea formed a single landmass known as Sahul, connected by an extensive land bridge across the Arafura Sea, Gulf of Carpentaria, and Torres Strait. The continental coastline extended much further out into the Timor Sea, reducing the travelling distance between Timor and Sahul to about 90 kilometers during times of low sea levels.
Genomic studies and archaeological evidence support the theory of a single migration into Sahul before the arrival of Modern Asians. This migration is believed to have occurred via a southern route out of Africa, expanding into South and Southeast Asia before reaching Sahul. The ancestors of Aboriginal Australians shared this migration route with the ancestors of Ancient Ancestral South Indians (AASI), Andamanese, East Asians, and other Australasians such as Papuans.
While the exact routes and methods of migration remain a mystery, the settlement of Australia by early humans is considered one of their greatest achievements. It involved a voyage of many days across a chain of islands in treacherous waters, challenging the assumption that early humans lacked the necessary maritime technology or knowledge.

Arrival in Australia 50,000-65,000 years ago
The ancestors of today's Aboriginal Australians first migrated to the continent between 50,000 and 65,000 years ago. During this time, Australia and New Guinea formed a single landmass known as Sahul, connected by an extensive land bridge across the Arafura Sea, Gulf of Carpentaria and Torres Strait. This period is referred to as prehistory as there is no written documentation of these events. However, Aboriginal oral tradition and rock art provide some insight into this era.
The first people are thought to have landed in the Kimberley region of Western Australia, with archaeological evidence of ancient Aboriginal peoples' living sites found across the continent in the form of fishing traps and weirs, stone-base huts, fireplaces, and remains of meals. Genomic studies indicate that the ancestors of Aboriginal Australians belonged to the southern route dispersal following the "out of Africa" exit, which expanded into South and Southeast Asia before diverging into the ancestors of Ancient Ancestral South Indians (AASI), Andamanese, East Asians, and other Australasians.
The migration to Australia is believed to have occurred during a period of glaciation, when sea levels were much lower than they are today, reducing the travelling distance between Timor and Sahul to about 90 kilometres. This presented a unique opportunity for early humans to migrate by island hopping or using primitive boats, marking one of the greatest achievements of early humans in crossing a major sea. The exact route and methods used by these ancient people remain a mystery, as it was assumed that early humans lacked the necessary maritime technology to make such a journey.
The arrival of the first Australians may have been a deliberate attempt to settle new territory or an accidental result of being caught in monsoon winds. The settlement of Australia marks the first unequivocal evidence of a major sea crossing, showcasing the complex capabilities of ancient humans. The exact number of populations that settled in Australia prior to European colonisation is unknown, but the continued use of Stone Age tools and evidence of land management indicate a landscape curated by thousands of years of innovation and adaptation.

Settlement across the continent
The prehistory of Australia refers to the period between the first human habitation of the Australian continent and the colonisation of Australia in 1788. Most evidence suggests that this period began between 50,000 and 65,000 years ago, with the migration of the ancestors of today's Aboriginal Australians.
The ancestors of Aboriginal Australians are thought to have migrated to the continent in waves, via land bridges and short sea crossings from what is now Southeast Asia. During the Pleistocene epoch, sea levels were much lower than they are today, and Australia and New Guinea formed a single landmass known as Sahul, connected by an extensive land bridge across the Arafura Sea, Gulf of Carpentaria and Torres Strait.
Genomic studies suggest that the peopling of Australia happened between 43,000 to 60,000 years ago, and archaeological evidence indicates that settlement across the continent was achieved within 6,000 years. The modelling of likely migration routes suggests that the first people landed in the Kimberley region of Western Australia, and spread across the continent via "superhighways", similar to the highways and stock routes in Australia today.
The lifestyle practices of these early settlers varied across the continent, depending on climate, environment and natural resources. For example, in the Lake Condah region of western Victoria, the inhabitants built semi-permanent stone and bark huts, while also moving across their territory several times a year to exploit seasonal food sources. In semi-arid areas, millet was harvested and stored, while in tropical areas, the tops of yams were replanted.
The use of stone tools is also evident in the archaeological record, with the oldest ground stone tools in Australia dating to around 30,000 years ago. Rock art also plays a significant role in Aboriginal culture and has survived in the archaeological record for over 30,000 years.

Australia-New Guinea landmass
The Australia-New Guinea landmass, also known as Sahul, was formed when sea levels dropped during the Pleistocene epoch, exposing a land bridge across the Arafura Sea, the Gulf of Carpentaria, and the Torres Strait. This land bridge connected the two landmasses, allowing for human migration between Australia and New Guinea.
The ancestors of modern Aboriginal Australians are believed to have migrated to the continent of Sahul around 50,000 to 65,000 years ago, during the closing stages of the Pleistocene epoch. At this time, sea levels were significantly lower, exposing land bridges and reducing the distance between islands, making migration by boat more feasible.
The journey to Sahul was not an easy one, requiring a voyage of many days across a chain of islands separated by treacherous waters. It is still a mystery how these ancient people navigated this complex route, as it is assumed that early humans did not possess the necessary maritime technology or knowledge. Despite the challenges, the successful migration to Sahul rates as one of the greatest achievements of early humans.
The settlement of Sahul marks the end of the "out-of-Africa" dispersal, which had previously peopled much of southern Eurasia. The genetic evidence supports the close ties between the Indigenous peoples of Australia and New Guinea, suggesting a recent common ancestry. These ancestral people continued to migrate across the Australian continent, with modelling suggesting they followed "superhighways" similar to modern highways and stock routes.
The Aboriginal people of Australia developed a rich culture, as evidenced by their rock art, which has survived for over 30,000 years. They also demonstrated advanced technological capabilities, such as the use of ground stone tools, which appeared in Australia about 10,000 years before they were seen in Europe. Additionally, they built elaborate fishing traps and stone-base huts, indicating a sophisticated understanding of their environment and resources.
