The first inhabitants of Australia, the Aboriginal Australians, have effectively been on their country as long as modern human populations have been outside of Africa. According to archaeological and genetic evidence, the first humans reached Australia at least 40,000 to 50,000 years ago, with some estimates placing this date even further back in time. These early Australians were likely the ancestors of the modern Aboriginal peoples, who view their presence in Australia as eternal, stretching back to the Dreaming, or the sacred time of creation.

The first inhabitants of Australia were ancestors of modern Aboriginal peoples
Aboriginal Australians have effectively been on the continent as long as modern human populations have been outside of Africa. Genetic evidence supports this deep connection, as Aboriginal populations have the distinctive marker of around 2.5% Neanderthal DNA, preserved in their genomes. This indicates that they were part of the original diaspora out of Africa, and moved to Australia almost immediately after.
The exact date of the first human occupation of Australia is a matter of ongoing research and discussion, with new evidence and improved dating techniques constantly pushing the date further back in time. Currently, the earliest archaeological evidence of human occupation in Australia dates to around 50,000 years ago, with some estimates ranging from 40,000 to 65,000 years ago. These dates are supported by genetic evidence from Aboriginal maternal, paternal, and genomic lineages.
The Madjedbebe rock shelter in Arnhem Land is one of the oldest sites showing the presence of humans in Australia, with human remains at Lake Mungo in New South Wales dated to around 41,000 years ago. Additionally, stone tools, rock art, ochre, shell middens, and charcoal deposits provide further evidence of the early human occupation of the continent.
The route taken by these first migrants is also a subject of discussion among archaeologists. It is widely believed that migration occurred during the Pleistocene epoch, when sea levels were lower and New Guinea and Tasmania were joined to the Australian continent. People likely arrived by sea, and the presence of ancient land that is now underwater suggests they may have island-hopped from Asia to Australia.
The Aboriginal and Torres Strait Islander view of creation, known as the Dreaming, holds that people have always been in Australia since the land was created. This belief system, with its own oral histories and rock art, provides a different perspective on the timeline of human occupation in Australia, one that is not solely based on scientific evidence.

They migrated during the Pleistocene epoch, when sea levels were lower
The first inhabitants of Australia, the ancestors of today's Aboriginal Australians, arrived on the continent at least 40,000 to 50,000 years ago. This is supported by archaeological evidence, such as stone tools and rock art, as well as genetic evidence. The migration occurred during the closing stages of the Pleistocene epoch, a time of repeated glaciation events that resulted in significantly lower sea levels than those of the present day.
During the Pleistocene epoch, sea levels in Australasia could have been over 100 metres lower than current levels due to water being locked up in polar ice caps. This meant that New Guinea and Tasmania were joined to the Australian continent, forming a landmass known as Sahul. The continental coastline extended much further into the Timor Sea, and a land bridge connected what is now the Gulf of Carpentaria and the Torres Strait.
Despite the closer proximity of landmasses, the sea still presented a significant obstacle for early migrants. Scientists believe that these ancestral people may have reached Australia by island-hopping, taking advantage of the numerous islands that would have been present during this period of lower sea levels. This theory is supported by the close genetic ties between Indigenous peoples of Australia and New Guinea, indicating a recent common ancestry.
The journey to Australia likely involved hazardous sea voyages in canoes or rafts, requiring advanced planning and a large group of people. While the exact motives for this migration remain unknown, it may have been driven by competition for resources or a desire to explore and settle new territories.
In summary, the first inhabitants of Australia migrated during the Pleistocene epoch, a time of lower sea levels, which facilitated their journey to the continent and shaped the early settlement patterns of these pioneering people.

Humans settled in Australia by 50,000 years ago
The Madjedbebe rock shelter in Arnhem Land is one of the oldest sites showing human presence in Australia, and the oldest human remains were found at Lake Mungo in New South Wales, dated to around 41,000 years ago. Archaeological evidence also indicates human habitation at the upper Swan River in Western Australia by about 40,000 years ago, and in Tasmania, which was connected to the continent by a land bridge, at least 40,000 years ago.
Aboriginal and Torres Strait Islander people believe that their people have always been in Australia since the Dreaming, the sacred time of creation. Scientific estimates of the first settlement of Australia are constantly changing as new evidence is discovered and dating techniques improve. The date of 50,000 years ago is based on genetic evidence from Aboriginal lineages, as well as archaeological evidence of stone tools, rock art, and charcoal deposits.
The migration to Australia is believed to have involved advanced planning and sailing or paddling skills, with a group of possibly more than 100 to 400 people making the journey. This rapid dispersal is thought to be reflected in the genetic diversity of Aboriginal groups, who have incredibly long and deep connections to their particular regions within the country. The settlement of Australia is considered one of the greatest achievements of early humans, demonstrating their capacity for major sea crossings and exploration.

Aboriginal Australians have been on the continent as long as modern humans have been outside of Africa
Aboriginal Australians have effectively been on the continent as long as modern human populations have been outside of Africa. According to Aboriginal and Torres Strait Islander beliefs, people have always been in Australia since the Dreaming, the time of creation of the world.
Scientists and archaeologists, on the other hand, believe that the first people arrived in Australia between 50,000 and 65,000 years ago, with the most recent studies suggesting that the first humans reached the continent around 50,000 years ago. This estimate is supported by archaeological evidence, which shows that modern humans had spread to Australia by at least 50,000 years ago, as well as genetic evidence from Aboriginal maternal, paternal, and genomic lineages.
The first Australians likely migrated from Southeast Asia, navigating across large stretches of water during a period of glaciation when sea levels were lower than they are today. They may have travelled by island-hopping, taking advantage of the reduced distances between islands and the Australian mainland. The journey would have required advanced planning skills and involved a group of more than 100 to 400 people paddling on rafts.
The Aboriginal population in Australia grew over time, with estimates ranging from 770,000 to 1.2 million people at the time of first European settlement in 1788. The population peaked at approximately 1.2 million people 500 years ago, possibly influenced by factors such as climate change, the arrival of the dingo, and the adoption of new tools.
In summary, Aboriginal Australians have a deep connection to their country, with a history that stretches back at least 50,000 years. Their presence in Australia coincides with the dispersal of modern human populations outside of Africa, highlighting the significance of this period in the global migration and settlement of our ancestors.

Archaeological evidence of human habitation has been found in Western Australia
The prehistory of Australia refers to the period between the first human habitation of the Australian continent and the colonisation of Australia in 1788, which marked the start of consistent written documentation of Australia. This period is estimated to span between 50,000 and 65,000 years ago.
Archaeological evidence of human habitation in Western Australia has been found in various locations. At the upper Swan River in Western Australia, archaeological evidence indicates human habitation by about 40,000 years ago. A 2018 study using archaeobotany dated evidence of human habitation at Karnatukul (Serpent's Glen) in the Carnarvon Range in the Little Sandy Desert in Western Australia to around 50,000 years ago, 20,000 years earlier than previously thought. The site at Karnatukul also showed continuous human habitation since that time.
In addition to these sites, Devil's Lair in southwest Western Australia is another location where evidence of early human habitation has been discovered. While the exact date of the earliest occupation of the Australian continent is still being debated and refined, archaeological evidence and Indigenous oral traditions provide valuable insights into the prehistory of Australia.
The settlement of Australia by early humans involved a major sea crossing, which is considered one of their greatest achievements. Migration occurred during the Pleistocene epoch, when sea levels were lower, and New Guinea and Tasmania were joined to the continent by land bridges. The use of fire to shape the Australian environment also dates back to this period, with evidence suggesting its deliberate use by hunter-gatherers about 46,000 years ago.
Overall, archaeological evidence and research continue to enhance our understanding of the early human habitation of Western Australia and the broader continent, shedding light on the rich and complex history of Aboriginal Australian culture.
