Humans first migrated toAustralia 50,000 to 65,000 years ago, and over time formed as many as 500linguistic and territorial groups.[3] In the past, Aboriginal people lived over large sections of thecontinental shelf. They were isolated on many of the smaller offshore islands andTasmania when the land was inundated at the start of theHoloceneinter-glacial period, about 11,700 years ago. Despite this, Aboriginal people maintained extensive networks within the continent and certain groups maintained relationships withTorres Strait Islanders and theMakassar people of modern-day Indonesia.
Over the millennia, Aboriginal people developed complex trade networks, inter-cultural relationships, law and religions,[3][4] which make up some of the oldest continuous cultures in the world.[5] At the time of European colonisation of Australia, the Aboriginal people spoke more than 250 differentlanguages,[6] possessed varying degrees of technology, and lived in various types of settlements. Languages (or dialects) and language-associated groups of people are connected with stretches of territory known as "Country", with which they have a profound spiritual connection.
Contemporary Aboriginal beliefs are shaped by traditional beliefs, the disruption of colonisation, religions brought to the continent by later migrants, and contemporary issues.[7][8][9] Just over half hold secular or other spiritual beliefs or no religious affiliation; about 40% are Christian; and about 1% adhere to a traditional Aboriginal religion.[10] Traditional cultural beliefs are passed down and shared throughdancing,stories,songlines, andart that collectively weave anontology of modern daily life and ancient creation known asthe Dreaming.
Studies of Aboriginal groups' genetic makeup are ongoing, but evidence suggests that they have genetic inheritance from ancient Asian peoples. Aboriginal Australians andPapuans shared the samepaleocontinentSahul, but became genetically distinct about 37,000 years ago.[11] Aboriginal Australians have a broadly shared, complex genetic history, but only in the last 200 years have they been defined by others as, and started to self-identify as, a single group.Aboriginal identity has changed over time and place, with family lineage, self-identification, and community acceptance all of varying importance.
The2021 census shows that there were over 944,000 Aboriginal people, comprising 3.7% of Australia's population.[1][note 1] Over 80% of Aboriginal people today speakEnglish at home, and about 77,000 speak an Indigenous language at home. Aboriginal people, along with Torres Strait Islander people, suffer a number of severehealth and economic deprivations in comparison with the wider Australian community.
Archeological evidence indicates that the ancestors of today's Aboriginal Australians first migrated to the continent 50,000 to 65,000 years ago.[13][14][15][16] Genomic studies suggest that the peopling of Australia happened between 43,000 and 60,000 years ago.[17][18][19][20]
Early human migration to Australia was achieved when it formed a part of theSahul continent, connected to the island of New Guinea via aland bridge.[21] This would have nevertheless required crossing the sea at theWallace Line.[22] It is also possible that people came by island-hopping via an island chain betweenSulawesi and New Guinea, reaching North Western Australia viaTimor.[23] As sea levels rose, the people on theAustralian mainland and nearby islands became increasingly isolated, some on Tasmania and some of the smaller offshore islands when the land was inundated at the start of theHolocene, theinter-glacial period that started about 11,700 years ago.[24]
Aboriginal Australians may have one of the oldest continuous cultures on earth.[27] InArnhem Land in theNorthern Territory, oral histories comprising complex narratives have been passed down byYolngu people through hundreds of generations. TheAboriginal rock art, dated by modern techniques, shows that their culture has continued from ancient times.[28]
While the commonly accepted date for the diversification of modern humans following theOut of Africa migration is placed at 60–50,000 years ago, there is, however, evidence that Aboriginal Australians may carry ancestry from an earlier human diaspora (xOoA) that originated 75,000 to 62,000 years ago. This earlier group has been estimated to have possibly contributed around 2% ancestry to modern Aboriginal Australians.[34][35]
Mallick et al. 2016 and Mark Lipson et al. 2017 found the bifurcation of Eastern Eurasians and Western Eurasians dates to at least 45,000 years ago, with indigenous Australians nested inside the Eastern Eurasian clade.[36][32] Aboriginal Australians, together withPapuans, may either form a sister clade to a single mainland Asian clade consisting of the AASI, Andamanese and East Asians, and to the exclusion of West Eurasians,[37] or alternatively are nested within the Eastern Eurasian cluster without a strong internal cladal structure against mainland Asian lineages.[32]
Genetic data on indigenous populations ofBorneo andMalaysia showed them to be closer related to other mainland Asian groups, than compared to the groups from Papua New Guinea and Australia. This indicates that populations in Australia were isolated for a long time from the rest of Southeast Asia. They remained untouched by migrations and population expansions into that area, which can be explained by theWallace line.[38]
Uniparentals
The most commonY-chromosome haplogroups among Aboriginal Australians isC1b2, followed by haplogroupsS andM; these latter haplogroups are also very frequent among Papuans.[39]
Other studies
In a 2001 study, blood samples were collected from someWarlpiri people in theNorthern Territory to study their genetic makeup (which is not representative of all Aboriginal peoples in Australia). The study concluded that the Warlpiri are descended from ancient Asians whose DNA is still somewhat present in Southeastern Asian groups, although greatly diminished. The Warlpiri DNA lacks certain information found in modern Asian genomes, and carries information not found in other genomes. This reinforces the idea of ancient Aboriginal isolation.[38]
Genetic data extracted in 2011 by Morten Rasmussen et al., who took aDNA sample from an early-20th-century lock of an Aboriginal person's hair, found that the Aboriginal ancestors probably migrated throughSouth Asia andMaritime Southeast Asia, into Australia, where they stayed. As a result, outside of Africa, the Aboriginal peoples have occupied the same territory continuously longer than any other human populations. These findings suggest that modern Aboriginal Australians are the direct descendants of the eastern wave, who left Africa up to 75,000 years ago.[40][41]
The Rasmussen study also found evidence that Aboriginal peoples carry some genes associated with theDenisovans (a species of human related to but distinct fromNeanderthals) of Asia; the study suggests that there is an increase inallele sharing between the Denisovan and Aboriginal Australian genomes, compared to other Eurasians or Africans. Examining DNA from a finger bone excavated inSiberia, researchers concluded that the Denisovans migrated fromSiberia to tropical parts of Asia and that they interbred with modern humans in Southeast Asia 44,000 years BP, before Australia separated from New Guinea approximately 11,700 years BP. They contributed DNA to Aboriginal Australians and to present-day New Guineans and an indigenous tribe in the Philippines known asMamanwa. This study confirms Aboriginal Australians as one of the oldest living populations in the world. They are possibly the oldest outside Africa, and they may have the oldest continuous culture on the planet.[42]
A 2016 study at theUniversity of Cambridge suggests that it was about 50,000 years ago that these peoples reachedSahul (thesupercontinent consisting of present-day Australia and its islands andNew Guinea). The sea levels rose and isolated Australia about 10,000 years ago, but Aboriginal Australians and Papuans diverged from each other genetically earlier, about 37,000 years BP, possibly because the remaining land bridge was impassable. This isolation makes the Aboriginal people the world's oldest culture. The study also found evidence of an unknownhominin group, distantly related to Denisovans, with whom the Aboriginal and Papuan ancestors must have interbred, leaving a trace of about 4% in most Aboriginal Australians' genome. There is, however, increased genetic diversity among Aboriginal Australians based on geographical distribution.[43][11]
Carlhoff et al. 2021 analysed aHolocene hunter-gatherer sample ("Leang Panninge") fromSouth Sulawesi, which shares high amounts of genetic drift with Aboriginal Australians and Papuans. This suggests that a population split from the common ancestor of Aboriginal Australians and Papuans. The sample also shows genetic affinity with East Asians and the Andamanese people of South Asia. The authors note that this hunter-gatherer sample can be modelled with ~50% Australian/Papuan-related ancestry and either with ~50% East Asian or Andamanese Onge ancestry, highlighting the deep split between Leang Panninge and Aboriginal/Papuans.[44][note 2]
Two genetic studies by Larena et al. 2021 found thatPhilippinesNegrito people split from the common ancestor of Aboriginal Australians and Papuans before the latter two diverged from each other, but after their common ancestor diverged from the ancestor ofEast Asian peoples.[45][46][47]
Changes about 4,000 years ago
Thedingo reached Australia about 4,000 years ago. Near that time, there were changes in language (with thePama-Nyungan language family spreading over most of the mainland), and instone tool technology. Smaller tools were used. Human contact has thus been inferred, and genetic data of two kinds have been proposed to support a gene flow from India to Australia: firstly, signs of South Asian components in Aboriginal Australian genomes, reported on the basis of genome-wideSNP data; and secondly, the existence of aY chromosome (male) lineage, designatedhaplogroup C∗, with the most recent common ancestor about 5,000 years ago.[48]
The first type of evidence comes from a 2013 study by theMax Planck Institute for Evolutionary Anthropology using large-scalegenotyping data from a pool of Aboriginal Australians, New Guineans, island Southeast Asians, and Indians. It found that the New Guinea andMamanwa (Philippines area) groups diverged from the Aboriginal about 36,000 years ago (there is supporting evidence that these populations are descended from migrants taking an early "southern route" out of Africa, before other groups in the area).[citation needed] Also the Indian and Australian populations mixed long before European contact, with this gene flow occurring during the Holocene (c. 4,200 years ago).[49] The researchers had two theories for this: either some Indians had contact with people in Indonesia who eventually transferred those Indian genes to Aboriginal Australians, or a group of Indians migrated from India to Australia and intermingled with the locals directly.[50][51]
However, a 2016 study inCurrent Biology by Anders Bergström et al. excluded the Y chromosome as providing evidence for recent gene flow from India into Australia. The study authors sequenced 13 Aboriginal Australian Y chromosomes using recent advances ingene sequencing technology. They investigated their divergence times from Y chromosomes in other continents, including comparing the haplogroup C chromosomes. They found a divergence time of about 54,100 years between the Sahul C chromosome and its closest relative C5, as well as about 54,300 years between haplogroups K*/M and their closest haplogroups R and Q. The deep divergence time of 50,000-plus years with the South Asian chromosome and "the fact that the Aboriginal Australian Cs share a more recent common ancestor with Papuan Cs" excludes any recent genetic contact.[48]
The 2016 study's authors concluded that, although this does not disprove the presence of any Holocene gene flow or non-genetic influences from South Asia at that time, and the appearance of the dingo does provide strong evidence for external contacts, the evidence overall is consistent with a complete lack of gene flow, and points to indigenous origins for the technological and linguistic changes. They attributed the disparity between their results and previous findings to improvements in technology; none of the other studies had utilised complete Y chromosome sequencing, which has the highest precision. For example, use of a ten Y STRs method has been shown to massively underestimate divergence times. Gene flow across the island-dotted 150-kilometre-wide (93 mi) Torres Strait, is both geographically plausible and demonstrated by the data, although at this point it could not be determined from this study when within the last 10,000 years it may have occurred—newer analytical techniques have the potential to address such questions.[48]
Bergstrom's 2018 doctoral thesis looking at the population of Sahul suggests that other than relatively recent admixture, the populations of the region appear to have been genetically independent from the rest of the world since their divergence about 50,000 years ago. He writes "There is no evidence for South Asian gene flow to Australia .... Despite Sahul being a single connected landmass until [8,000 years ago], different groups across Australia are nearly equally related to Papuans, and vice versa, and the two appear to have separated genetically already [about 30,000 years ago]."[52]
Environmental adaptations
An Aboriginal encampment near theAdelaide foothills in an 1854 painting by Alexander Schramm
Aboriginal Australians possess inherited abilities to adapt to a wide range of environmental temperatures in various ways. A study in 1958 comparing cold adaptation in the desert-dwellingPitjantjatjara people compared with a group of European people showed that the cooling adaptation of the Aboriginal group differed from that of the white people, and that they were able to sleep more soundly through a cold desert night.[53] A 2014Cambridge University study found that a beneficial mutation in two genes which regulatethyroxine, a hormone involved in regulating bodymetabolism, helps to regulate body temperature in response to fever. The effect of this is that the desert people are able to have a higher body temperature without accelerating the activity of the whole of the body, which can be especially detrimental in childhood diseases. This helps protect people to survive the side-effects of infection.[54][55]
Population growth and location
Based on the 2021 census, theAustralian Bureau of Statistics estimates there were 901,655 Aboriginal Australians, and 42,515 who identified as both Aboriginal Australian and Torres Strait Islander. These groups comprise 3.7% of the total Australian population. About 39,540 people identified as Torres Strait Islander, which is a different ethnic group from Aboriginal Australian.[56]

*These are initial counts and differ from the final estimates which adjust for undercounting.[56][57]
Based on initial 2021 census counts, the Aboriginal and Torres Strait islander population grew 25.2%, since the previous census in 2016.[57]Demographic factors – births, deaths and migration[note 3] – accounted for 43.5% of the increase (71,086 people). In turn, 76.2% of that increase was attributed to people aged 0–19 years in 2021, broken down as 52.5% for 0–4 year olds (births since 2016) and 23.7% for 5–19 year olds.[57]
Reasons for the increase in Aboriginal population also include non-demographic factors. These include changes in individuals' identification as Aboriginal or Torres Strait Islander in different censuses, and individuals completing a census form in 2021 but not in 2016. These factors accounted for 56.5% of the increase in the Aboriginal and Torres Strait Islander population. The increase was higher than observed between 2011 and 2016 (39.0%) and 2006–2011 (38.7%).[57]
The distribution of the Aboriginal Australian population (including those who identify as both Aboriginal and Torres Strait Islander) by state and territory is: New South Wales (35.3%), Queensland (26.3%), Western Australia (12.5%), Victoria (8.1%), Northern Territory (8.0%), South Australia (5.4%), Tasmania (3.4%) and Australian Capital Territory (1.0%).[58]
Indigenous Australians (including Torres Strait Islanders) are less likely to live in the major Australian cities than are non-Indigenous Australians (41% compared with 73%). They are more likely to live in remote or very remote areas (15% compared with 1.4%)[58]
Although humans arrived in Australia 50,000 to 65,000 years ago,[59][60] it is possible that the ancestor language of existing Aboriginal languages is as recent as 12,000 years old.[61] Over 250Australian Aboriginal languages are thought to have existed at the time of first European contact.[62]
As of 2021, 84% of Aboriginal and Torres Strait Islanders spoke only English at home.[63] The National Indigenous Languages Survey (NILS) for 2018-19 found that more than 120 Indigenous language varieties were in use or being revived, although 70 of those in use are endangered.[64] The 2021 census found that 167 Indigenous languages were spoken at home by 76,978 Indigenous Australians.[65] NILS and the Australian Bureau of Statistics use different classifications for Indigenous Australian languages.[66]
According to the 2021 census, the classifiable Aboriginal languages with the most speakers are Kriol (7,403),Djambarrpuyngu (3,839),Pitjantjatjara (3,399),Warlpiri (2,592),Murrinh Patha (2,063) andTiwi (2,053). There were also over 10,000 people who spoke an Indigenous language which could not be further defined or classified.[67]
Creoles
A number of English-basedcreoles have arisen in Australia after European contact, of which Kriol is among the strongest and fastest-growing Aboriginal languages. Kriol is spoken in theNorthern Territory andWestern Australia. It is estimated that there are 20,000 to 30,000 speakers of Indigenous creole languages.[68]
Before British colonisation, there were perhaps five to sixteen languages on Tasmania,[69] possibly related to one another in fourlanguage families.[70] The last speaker of a traditional Tasmanian language,Fanny Cochrane Smith, died in 1905.[71]Palawa kani is an in-progress constructed language, built from a composite of surviving words from various Tasmanian Aboriginal languages.[72]
Traditional Indigenous languages often incorporated sign systems to aid communication with the hearing impaired, to complement verbal communication, and to replace verbal communication when the spoken language was forbidden for cultural reasons. Many of these sign systems are still in use.[73]
Dispersing across the Australian continent over time, the ancient people expanded and differentiated into distinct groups, each with its own language and culture.[74] More than 400 distinct Australian Aboriginalpeoples have been identified, distinguished by names designating theirancestral languages, dialects, or distinctive speech patterns.[75] According to notedanthropologist,archaeologist and sociologistHarry Lourandos, historically, these groups lived in three main cultural areas, the Northern, Southern and Central cultural areas. The Northern and Southern areas, having richer natural marine and woodland resources, were more densely populated than the Central area.[74]
However, these lists are neither exhaustive nor definitive, and there are overlaps. Different approaches have been taken by non-Aboriginal scholars in trying to understand and define Aboriginal culture and societies, some focusing on the micro-level (tribe, clan, etc.), and others on shared languages and cultural practices spread over large regions defined by ecological factors.Anthropologists have encountered many difficulties in trying to define what constitutes an Aboriginal people/community/group/tribe, let alone naming them. Knowledge of pre-colonial Aboriginal cultures and societal groupings is still largely dependent on the observers' interpretations, which were filtered through colonial ways of viewing societies.[79]
The termAboriginal Australians includes many distinct peoples who have developed across Australia for over 50,000 years.[80][81] These peoples have a broadly shared, though complex, genetic history,[82][51] but it is only in the last two hundred years that they have been defined and started to self-identify as a single group, socio-politically.[83][84] While some preferred the termAborigine toAboriginal in the past, as the latter was seen to have more directly discriminatory legal origins,[83] use of the termAborigine has declined in recent decades, as many consider the term an offensive and racist hangover from Australia's colonial era.[85][86]
The definition of the termAboriginal has changed over time and place, with family lineage, self-identification and community acceptance all being of varying importance.[87][88][89]
The termIndigenous Australians refers to Aboriginal Australians and Torres Strait Islander peoples, and the term is conventionally only used when both groups are included in the topic being addressed, or by self-identification by a person as Indigenous. (Torres Strait Islanders are ethnically and culturally distinct,[90] despite extensive cultural exchange with some of the Aboriginal groups,[91] and the Torres Strait Islands are mostly part of Queensland but have aseparate governmental status.) Some Aboriginal people object to being labelledIndigenous, as an artificial and denialist term, because some non-Aboriginal people have referred to themselves as indigenous because they were born in Australia.[84]
As of 2021, 51% of Indigenous people stated that they held a secular or other spiritual belief or no religious affiliation; 41% were affiliated to Christianity; and 1% were affiliated to a traditional Aboriginal religion.[92]
Australian Indigenous people have beliefs unique to each mob (tribe) and have a strong connection to the land.[93][5] Contemporary Indigenous Australian beliefs are a complex mixture, varying by region and individual across the continent.[7] They are shaped by traditional beliefs, the disruption of colonisation, religions brought to the continent by Europeans, and contemporary issues.[7][8][9] Traditional cultural beliefs are passed down and shared bydancing,stories,songlines andart—especiallyPapunya Tula (dot painting)—collectively telling the story of creation known asThe Dreamtime.[94][93] Additionally, traditional healers were also custodians of important Dreaming stories as well as their medical roles (for example theNgangkari in theWestern desert).[95] Some core structures and themes are shared across the continent with details and additional elements varying between language and cultural groups.[7] For example, in The Dreamtime of most regions, a spirit creates the earth then tells the humans to treat the animals and the earth in a way which is respectful to land. InNorthern Territory this is commonly said to be a huge snake or snakes that weaved its way through the earth and sky making the mountains and oceans. But in other places the spirits who created the world are known aswandjina rain and water spirits. Majorancestral spirits include theRainbow Serpent,Baiame,Dirawong andBunjil. Similarly, the Arrernte people of central Australia believed that humanity originated from great superhuman ancestors who brought the sun, wind and rain as a result of breaking through the surface of the Earth when waking from their slumber.[76]
Many Dreamtime stories are still belived by many Indigenous Australians to this day.[96]
Taken as a whole, Aboriginal Australians, along with Torres Strait Islander people, have a number of health and economic deprivations in comparison with the wider Australian community.[97][98]
Due to the aforementioned disadvantage, Aboriginal Australian communities experience a higher rate of suicide, as compared to non-indigenous communities. These issues stem from a variety of different causes unique to indigenous communities, such as historical trauma,[99] socioeconomic disadvantage, and decreased access to education and health care.[100] Also, this problem largely affects indigenous youth, as many indigenous youth may feel disconnected from their culture.[101]
To combat the increased suicide rate, many researchers have suggested that the inclusion of more cultural aspects into suicide prevention programs would help to combat mental health issues within the community. Past studies have found that many indigenous leaders and community members, do in fact, want more culturally-aware health care programs.[102] Similarly, culturally-relative programs targeting indigenous youth have actively challenged suicide ideation among younger indigenous populations, with many social and emotional wellbeing programs using cultural information to provide coping mechanisms and improving mental health.[103][104]

Theoutstation movement of the 1970s and 1980s, when Aboriginal people moved to tiny remote settlements on traditional land, brought health benefits,[105][106] but funding them proved expensive, training and employment opportunities were not provided in many cases, and support from governments dwindled in the 2000s, particularly in the era of theHoward government.[107][108][109]
Indigenous communities in remote Australia are often small, isolated towns with basic facilities, ontraditionally owned land. These communities have between 20 and 300 inhabitants and are often closed to outsiders for cultural reasons. The long-term viability and resilience of Aboriginal communities in desert areas has been discussed by scholars and policy-makers. A 2007 report by theCSIRO stressed the importance of taking a demand-driven approach to services in desert settlements, and concluded that "if top-down solutions continue to be imposed without appreciating the fundamental drivers of settlement in desert regions, then those solutions will continue to be partial, and ineffective in the long term."[110]
^This includes those who identified as both Aboriginal and Torres Strait Islander.
^TheqpGraph analysis confirmed this branching pattern, with the Leang Panninge individual branching off from the Near Oceanian clade after the Denisovan gene flow. The most supported topology indicates around 50% of a basal East Asian component contributing to the Leang Panninge genome (fig. 3c, supplementary figs. 7–11).
