It seems mapping your DNA is all the rage, from family history research to crime scene forensics. But for Australian Aboriginal people, or those searching their family tree, a DNA test will not necessarily give you confirmation of an indigenous Australian heritage.
If you receive the Aboriginal and Torres Strait Islander region in your DNA results, this tells you that you probably had an ancestor who was an Indigenous Australian. If you are Indigenous Australian and do not receive this region in your DNA results, this should not subtract from your identity in any way.
DNA samples of 594 self-declared Indigenous Australians from around the country were analysed and classified into mitochondrial haplogroups - genetic groups that share a common ancestor and often show a distinct distribution. The findings have been published in the Journal of Human Genetics.
You can provide a letter of Confirmation from a registered Aboriginal community organisation as proof of Aboriginality.
Doing your family history may help you obtain proof of your heritage. You might find a birth, death or marriage record that traces your family to a particular Aboriginal station or reserve. Or you might have oral history stories that can connect you to a particular area or person or photograph.

One Nation NSW has proposed to abolish self-identification and introduce a “new system” relying on DNA ancestry testing with a result requiring a finding of at least 25 per cent "Indigenous" before First Nations identification is accepted.
This means Aboriginal ancestors can only be reliably detected through direct maternal or paternal lines (using mitochondrial and Y-chromosome tests). The only two companies to offer “Aboriginality tests” – DNA Tribes and GTDNA – rely on short tandem repeat (STR) genetic testing.
On our calculation, with generations of 25 years and each having three children, one Aborigine could account for 2187 descendants over seven generations.
A new genomic study has revealed that Aboriginal Australians are the oldest known civilization on Earth, with ancestries stretching back roughly 75,000 years.
Some 90% of present-day Australian Aboriginals belong to the Pama-Nyungan linguistic family. This family originated only around 6,000 years ago, but according to the new study the people who speak the Pama-Nyungan languages today started to become genetically differentiated in Australia as early as 31,000 years ago.
Genetics. Genetic studies have revealed that Aboriginal Australians largely descended from an Eastern Eurasian population wave, and are most closely related to other Oceanians, such as Melanesians.
Indigenous Peoples are distinct social and cultural groups that share collective ancestral ties to the lands and natural resources where they live, occupy or from which they have been displaced.
2. Self identification and community recognition of applicants as Aborigines, particularly where there is evidence of a family history or tradition of Aboriginal descent passed on orally, can provide evidence of Aboriginal descent.
The original Australians were dark-skinned, but a large proportion of the country's Aborigines today are of mixed blood, and many appear to be white.
Results: The Aboriginal and non-Aboriginal populations had significantly different ABO and RhD distributions (P < 0.001). For Aboriginal individuals, 955/1686 (56.6%) were group O and 669/1686 (39.7%) were group A.
Losing Indian Status (Enfranchisement)
The process of losing one's Indian status for citizenship rights was called “enfranchisement.” Initially, any Indians who obtained a university degree and/or became a professional such as a doctor or lawyer would automatically lose their status.
Genetically, while Aboriginal Australians are most closely related to Melanesian and Papuan people, there is also another component that could indicate South Asian admixture or more recent European influence.
By comparing Aboriginal genomes to other groups, they conclude that Aborigines diverged from Eurasians between 50,000 and 70,000 years ago, after the whole group had already split from Africans.
Aboriginal origins
Humans are thought to have migrated to Northern Australia from Asia using primitive boats. A current theory holds that those early migrants themselves came out of Africa about 70,000 years ago, which would make Aboriginal Australians the oldest population of humans living outside Africa.
Wide nostrils of the aborigines again appear to depend on a small number of additive genes compared with the narrow nose of the white man. The lips of the aborigines tend to be thick throughout, but generally not everted.
Total brain volume was significantly smaller for Aborigines (1199 +/- 84 ml) compared to Caucasians (1386 +/- 98 ml). Significantly smaller volumes were also found for cerebellum, prosencephalon-mesencephalon unit, cerebral cortex, frontal cortex, parieto-occipitotemporal cortex, and hippocampus.
Yes. Plenty of tribal groups (their Mob) contain people of pure Aboriginal descent. The further North you go, generally, the purer the bloodline. It's fabulous that the oldest peoples in the world still exist happily on their original tribal lands.
The islands were settled by different seafaring Melanesian cultures such as the Torres Strait Islanders over 2500 years ago, and cultural interactions continued via this route with the Aboriginal people of northeast Australia.
While Indigenous Australians have inhabited the continent for tens of thousands of years, and traded with nearby islanders, the first documented landing on Australia by a European was in 1606. The Dutch explorer Willem Janszoon landed on the western side of Cape York Peninsula and charted about 300 km of coastline.
