Australian Aboriginal DNA
Genetic origins and closest populations · Australia · Oceania
Aboriginal Australians belong to the oldest continuous cultures on earth: people reached Australia, then joined to New Guinea in a single landmass called Sahul, at least 50,000 years ago. Before colonisation, more than 250 languages were spoken across the continent, most of them in the Pama-Nyungan family. In our model, the Australian Aboriginal average is 70.4% Papuan and Near Oceanian and 16.9% South Asian hunter-gatherer related, plus small traces. Our model has no Australian reference, so these shares describe a deep, distinct ancestry with stand-ins from New Guinea and southern India: Papuans and Aboriginal Australians share a common origin but have been separate for tens of thousands of years. This shows in the neighbours: the closest, the Baining of New Britain, is at 0.0658, and Ni-Vanuatu at 0.0779. The ancient results show continuity on the continent itself: people from Cairns about 420 years ago (0.0231), from Mapoon and Barham, and a 4,000-year-old individual from Willandra Lakes (0.0338).

This page sums up what the DNA of the Australian Aboriginal sample tells us about deep origins. It is built from the averaged Global25 (G25) coordinates of individuals sampled in Australia, listed in the G25 sheet as "Australian_Aboriginal", and it is one of 335 populations in our atlas. An average describes the group as a whole, not any single person in it.
Ancient make-up of the Australian Aboriginal average
In a model built from deep ancestral reference populations, the largest share of the Australian Aboriginal average, 70.4%, goes to Papuan and Near Oceanian, ahead of South Asian hunter-gatherer related (Irula proxy) (16.9%) and Southern Chinese Neolithic farmers (4.3%). The Papuan and Near Oceanian component reflects the ancestry of the first peoples of New Guinea and Australia. The South Asian hunter-gatherer related (Irula proxy) share (16.9%) reflects the deep hunter-gatherer ancestry of South Asia (Ancient Ancestral South Indians). With well over half of the total, this single source dominates the profile.
Smaller traces of Southern Chinese Neolithic farmers, Southeast Asian Neolithic farmers, Ancient Northeast Asians and Arctic Siberian (Nganasan-related) (under 5% each) also appear. At that level they can reflect real minor ancestry, but also simple model noise, so they should not be over-read. The model fits well (fit distance 0.015), so these proportions are a reasonable summary. This population was modelled with a global set of reference populations (ancient genomes, plus modern stand-ins where no suitable ancient genome exists), because West Eurasian sources alone cannot describe it.
Closest modern populations to Australian Aboriginal
Ranking every modern population by genetic distance puts Baining first for Australian Aboriginal, at 0.066, then Ni-Vanuatu and Nasoi. No modern population in the data is very close (the nearest is 0.066 away), which points to a distinctive genetic profile, often the mark of long isolation or of a mix that is rare elsewhere.
| # | Population | Distance | Closeness |
|---|---|---|---|
| 1 | Baining | 0.0658 | Moderate |
| 2 | Ni-Vanuatu | 0.0779 | Moderate |
| 3 | Nasoi | 0.0855 | Distant |
| 4 | Nasioi (Bougainville) | 0.0858 | Distant |
| 5 | Papuan (Highland B) | 0.0988 | Distant |
| 6 | Papuan (Coastal) | 0.1286 | Distant |
| 7 | Alor | 0.1724 | Distant |
| 8 | Korowai | 0.1922 | Distant |
| 9 | Papuan (Kosipe) | 0.1944 | Distant |
| 10 | Pantar | 0.1967 | Distant |
Distances are Euclidean distances between averaged G25 coordinates. On our scale, below 0.025 is very close, below 0.050 close, below 0.080 moderate, and beyond that distant.
Closest ancient populations to Australian Aboriginal
If we search ancient DNA for the best match to Australian Aboriginal, AUS Cairns 420BP (c. 1550 AD) comes first, at 0.023, with Australia Mapoon 112BP next. That is a very close match, which suggests strong genetic continuity between those ancient people (or close relatives of theirs) and the modern population. A close ancient match is not proof of direct descent: it means those individuals carried a similar overall mix of ancestry.

Ancient DNA from Australia
Our ancient DNA database holds 35 individuals excavated in present-day Australia, dated from about 350 AD to 1904 AD. The most frequent Y-DNA haplogroups among them are S1a (6), S1c (3) and F (1), and the most frequent mtDNA haplogroups are P5 (9), M42 (6) and P12 (5). These are people who lived on the same land in the past, not necessarily ancestors of today's Australian Aboriginal population.

About these numbers
Keep in mind that a population average is a statistical summary of a limited number of sampled individuals. Real people inside any group vary, some carry more of one ancestry and some less, and no genetic profile decides who is or is not Australian Aboriginal. Use these numbers as a map of deep ancestry, not as a label.
Method: averaged G25 coordinates, Euclidean distances to other modern and ancient averages, and a non-negative least-squares model against deep ancestral reference populations (data generated 2026-10-01). Read the full method.

Frequently asked questions
What is the ancient genetic make-up of Australian Aboriginal?
Modelled with deep ancestral reference populations, the Australian Aboriginal average is about 70.4% Papuan and Near Oceanian, 16.9% South Asian hunter-gatherer related (Irula proxy) and 4.3% Southern Chinese Neolithic farmers. These proportions are model estimates for a group average, not exact values for any one person.
Which populations are genetically closest to Australian Aboriginal?
In the G25 data, the closest modern populations to the Australian Aboriginal average are Baining, Ni-Vanuatu and Nasoi. The closest ancient matches are AUS Cairns 420BP, Australia Mapoon 112BP and Australia Barham 1600-1400BP.
Can a DNA test tell me if I am Australian Aboriginal?
No DNA test can confirm an ethnicity or a nationality. What DNA can show is how similar your genome is to the sampled Australian Aboriginal average and to its neighbours. If you have G25 coordinates, paste them in the comparison box on this page to check that for free.
Which ExploreYourDNA report suits Australian Aboriginal ancestry?
Our regional report for this part of the world does not fit the Australian Aboriginal average closely, so the full Advanced Ancestry Report (no regional focus) is the better choice. The DNA Mega-Analysis adds Neanderthal %, traits and closest ancient populations. The free Report Finder checks every report against your own DNA first.
Where does the data on this page come from?
From the averaged Global25 (G25) coordinates of the sampled individuals: genetic distances to other modern and ancient population averages, and a non-negative least-squares model against deep ancestral reference populations.
