Their kinship system was first studied by Howitt, who took it as exemplifying a form of one of the most socially backward of Australian tribes. Alfred Radcliffe-Brown analysed the Diyari kinship structure as a variant of the Arrernte system. Their moieties were Matharri and Kararrhu, in accordance with the general divisions among speakers of Thura-Yura languages in South Australia. Social system Gason thought the Diyari extremely treacherous, nourished by suspicion from infancy. At the same time, he said they displayed exemplary hospitality, revered the aged, and adored their children. Any stranger who passed through their camp, was provided with food. Infanticide was widespread, by Gason's calculation, affecting some 30% of births and was performed by the mother. They were very attached to their camp dingos, treating them as they would a human. Native title The Dieri Aboriginal Corporation (DAC) incorporated in 2001 and by 2014 had 600 members living in Marree, Lyndhurst, Port Augusta, Whyalla and in Broken Hill in New South Wales.
