The human history of Australia begins with the arrival of the ancestors of Aboriginal Australians, who settled throughout the continent and on many nearby islands. The earliest human occupation of Australia is dated to around 65,000 years ago, with evidence of human remains at Lake Mungo in New South Wales dated to around 41,000 years ago. Scientists believe that the first Australians came from somewhere else, likely the area that is now Timor, and made their way through Maritime Southeast Asia, before migrating southwards towards the Australian continent. This journey would have involved a canoe voyage of about 90 to 150 kilometres of open water, a remarkable maritime achievement.

What You'll Learn
Humans likely arrived in Australia between 50,000 and 65,000 years ago
The Madjedbebe rock shelter in Arnhem Land is the oldest site showing the presence of humans in Australia. The earliest Aboriginal rock art, consisting of hand-prints, hand-stencils, and engravings, has been dated to 35,000 years ago. The oldest human remains found are at Lake Mungo in New South Wales, dated to around 41,000 years ago.
The journey to Australia was likely a remarkable maritime achievement, involving a canoe voyage of about 90 to 150 kilometres of open water. At the time, sea levels were lower, and much of Indonesia was land, reducing the travelling distance between Timor and Sahul (the larger land mass that included modern-day Australia). This would have made the journey slightly easier for these early humans.
The settlement of Australia is the first unequivocal evidence of a major sea crossing and is considered one of the greatest achievements of early humans. The Aboriginal Australians developed a unique artistic, musical, and spiritual culture, with traditions that are among the longest surviving in human history.

They probably travelled from Maritime Southeast Asia
The human history of Australia commenced with the arrival of the first ancestors of Aboriginal Australians from Maritime Southeast Asia between 50,000 and 65,000 years ago. They probably travelled from Maritime Southeast Asia, which was possible due to the lower sea levels at the time. Much of Indonesia was land, and the travelling distance between Timor and Sahul (the larger land mass that included modern-day Australia) would have been reduced to about 90 kilometres. This would have been a remarkable maritime achievement, and watercraft would have been necessary to cross the treacherous passage.
The ancestors of today's Aboriginal Australians settled throughout continental Australia and many nearby islands. They developed a unique artistic, musical, and spiritual culture, with the earliest Aboriginal rock art consisting of hand-prints, hand-stencils, and engravings of circles, tracks, lines, and cupules, dated to 35,000 years ago. Around 20,000 years ago, Aboriginal artists began depicting humans and animals.
The Aboriginal population is estimated to have ranged from 300,000 to one million at the time of first European contact. They were complex hunter-gatherers with diverse economies and societies, consisting of about 600 tribes or nations and 250 languages with various dialects. Certain groups engaged in fire-stick farming, fish farming, and built semi-permanent shelters. The spread of the population also altered the Australian environment, with fire-stick farming being used in many parts of Australia to clear vegetation, make travel easier, and create open grasslands rich in food sources.
Genetic data also supports the theory that humans travelled from Maritime Southeast Asia to Australia. A 2013 study found that the New Guinea and Mamanwa (Philippines area) groups diverged from Aboriginal Australians about 36,000 years ago, supporting the evidence that these populations are descended from migrants taking an early "southern route" out of Africa. Additionally, the existence of a Y chromosome (male) lineage designated haplogroup C* provides evidence of gene flow from India to Australia, with the most recent common ancestor estimated to be around 5,000 years ago.

Watercraft were likely used to cross the sea
The ancestors of today's Aboriginal Australians likely travelled to Australia from Maritime Southeast Asia between 50,000 and 65,000 years ago. During this time, sea levels were lower, and much of Indonesia was land. The distance between Timor and Sahul (the larger land mass that included modern-day Australia) would have been reduced to about 90 kilometres. This would have been a treacherous passage, not possible by swimming, so watercraft are the obvious solution. These watercraft need not have been complex, and they may not have preserved over time.
The settlement of Australia is the first unequivocal evidence of a major sea crossing and rates as one of the greatest achievements of early humans. The Aboriginal population was confronted with significant changes to climate and environment. About 30,000 years ago, sea levels began to fall, temperatures in the southeast of the continent dropped by as much as 9 degrees Celsius, and the interior of Australia became more arid.
The Aboriginal Australians developed a unique artistic and spiritual culture. The earliest Aboriginal rock art consists of handprints, hand stencils, and engravings of circles, tracks, lines, and cupules, dated to 35,000 years ago. Around 20,000 years ago, Aboriginal artists began depicting humans and animals.

Humans may have been motivated to migrate by rising sea levels
Humans may have been motivated to migrate to Australia by rising sea levels. The earliest evidence of human occupation in Australia has been dated to around 65,000 years ago, during the middle of a major ice age. At this time, sea levels were more than 122 meters lower than they are today, and much of Indonesia was land. As the climate became warmer, the ice melted, and the sea levels rose.
The rising sea levels would have reduced the amount of usable land and increased population pressure, forcing humans to expand into new areas. This is supported by the fact that the earliest human remains in Australia, found at Lake Mungo in New South Wales, show evidence of a range of physical variation that would be expected in a single, geographically widespread population.
Additionally, the settlement of Australia required crossing a significant stretch of water, which would have been easier during periods of lower sea levels. During times of low sea levels, the travelling distance between Timor and Sahul, the larger land mass that included modern-day Australia, would have been reduced to about 90 kilometres. This would have made the journey less treacherous and more manageable for early humans.
The motive and circumstances regarding the arrival of the first Australians are still a matter of conjecture. However, the consensus is that modern humans migrated from Eastern Africa to the Middle East, then Southern and Southeast Asia, before arriving in Australia. This migration was likely facilitated by the development of some form of watercraft, as there is no evidence that humans could have reached Australia without them.
The rising sea levels at the end of the Ice Age may have also played a role in covering the traces of early migration routes with water and sediments, making it more challenging to piece together the exact motivations and circumstances of the first humans to populate Australia.

The Aboriginal population was diverse, with many tribes and languages
The Aboriginal population in Australia was diverse, with about 600 tribes or nations and 250 languages with various dialects. The ancestors of these Aboriginal Australians are believed to have originated in Africa and travelled through Maritime Southeast Asia to Australia between 50,000 and 65,000 years ago. The journey to Australia was made possible by the use of watercraft, with early humans navigating treacherous passages of open water. The Aboriginal population faced significant changes in the climate and environment, with sea levels falling and temperatures dropping about 30,000 years ago.
The Aboriginal people developed a unique artistic and spiritual culture, with the earliest Aboriginal rock art consisting of hand-prints, hand-stencils, and engravings of circles, tracks, lines, and cupules, dated to 35,000 years ago. They also established artistic, musical, and spiritual traditions that are among the longest-surviving in human history. Certain groups engaged in fire-stick farming, fish farming, and built semi-permanent shelters. The extent of agriculture practised by some groups is a subject of debate.
The genetic origins of the Aboriginal population are diverse, with evidence of interbreeding with other hominin species and gene flow from India. Modern Aboriginal people are believed to be the result of the assimilation of two genetic lineages, one descended from Indonesian Homo erectus and the other from Chinese Homo erectus. Human genomic differences continue to be studied to better understand the population's history.
The Torres Strait Islander people, while culturally and linguistically distinct from mainland Aboriginal peoples, are also a part of the diverse Aboriginal population. They settled the islands of Torres Strait about 4,000 years ago, obtaining their livelihood from seasonal horticulture and marine resources.
