PY Media states on its website:
Indulkana is an Anangu community, often referred to as the Iwantja Community, on the Anangu Pitjantjatjara Lands in the northwest of South Australia. Although Indulkana is regarded as a Pitjantjatjara community, the majority of people at Indulkana refer to themselves as Yankunytjatjara, which is a group having its origins in the eastern section of the Lands
ABS research indicated in 2003 that the 2001 census data showed that Indulkana had South Australia's highest proportions of Aboriginal residents (90%). Unlike other APY communities, Indulkana did not have one of the State's highest proportion of Australian-born residents, nor a high proportion of single parent families.
Like other APY communities, Indulkana did have one of the lowest percentages of home personal computer use (South Australia's lowest, 5%).
Indulkana was a standout from other APY communities in that it ranked in other categories that its sister communities did not. For instance, Indulkana had the highest proportion of 0-14 year olds in the State (35.0%), the State's third highest proportion of Professionals or Associate Professionals in the State (41.8%, following wealthy Adelaide Hills localities of Summertown and Bridgewater). This is perhaps explained by the town being situated close to the Stuart Highway and hence, perhaps, serving as a gateway to the APY Lands and - thus - an attractive place for non- Aboriginal professionals to be based.
Indulkana was the birthplace of 1984 Australian of the Year and former chairperson of the now-defunct Aboriginal and Torres Strait Islander Commission (ATSIC), Lowitja or "Lois" O'Donoghue AC CBE, who was born in the area. The State Library of South Australia records:
In August 1932, Lois O'Donoghue was a bright-eyed brown-skinned infant newly born into the Yankunytjatjara tribe in the remote North-West Reserve of South Australia. Her mother was a full blood of the tribe, and her father the owner of a pastoral station which later passed into the hands of the McLachlan family. This was not a casual relationship and Lois is the youngest of five children born to the same parents.
In 1934, members of the frankly paternalistic United Aborigines' Mission visited her Yankunytjatjara tribe at Indulkana, 200 miles north of Coober Pedy. They persuaded her mother it would be best for the child to be brought up at the Mission's Home for Children at Quorn. Without in any way approving such a policy, Lois acknowledges that she had a happy childhood there, and later at the Colebrook home at Eden Hills.
In the late 1990s, the Indulkana community invited the Aboriginal Drug and Alcohol Council (SA) Inc. to run a program to address the problem of petrol sniffing in their community .
There is an unsealed airstrip located close to the town.
"Iwantja Arts" provides an art centre operating with local artists. It has a gallery for sale of art work from across the Lands.
A doctor visits on a fortnightly basis and dental care (emergency) is available at Pukatja / Ernabella.
Indulkana is the only place on the APY Lands that provides an aged care facility for elders.
The University of South Australia runs an AnTEP program out of Indulkana, providing tertiary education in teaching with a view to people from the APY Lands teaching in culturally sensitive way on the Lands.
The Indulkana Anangu School was established after 1971, recounted on the School's website as follows:
Leslie Mingkilli wrote a letter to the South Australian Government on behalf of Indulkana Community asking for funding and help to establish a school. He wrote to the Government in the Pitjantjatjara language, insisting that a school be started at Indulkana. Leslie was educated at Ernabella (Pukatja) community where he learnt to read and write English and Pitjantjatjara. This dream finally came true when Leslie went to Adelaide and returned with David Emery, the first Principal and three teachers. The school began with tents and sheds made of timber and brush from the surrounding bush.
The school is supported by Aboriginal Education Workers and a computer facility with 24-networked computers with Internet access.
Indulkana has a community church (run by the Uniting Church in Australia.
Indulkana does not have a permanent police presence, though it has a police station. South Australian police are based at Marla and run patrols in the area. In the absence of police, the community is served by 2 community constables . The Indulkana police station is considered by the Police Association of South Australia to be a "disgrace", "dirty, ill-equipped sheds". .
Indulkana has a community oval.
For State elections (ie to elect the Parliament of South Australia), a mobile polling booth is taken to Indulkana.
