The Dadi Dadi or Tatitati are an Australian Aboriginal tribe whose traditional lands are located along the southern banks of the Murray River in Victoria Australia.
They spoke a nearly extinct language of the Lower Murray languages, which form a branch of the Pama-Nyungan language family. During the 1960s and 1970s samples of the language were recorded by Luise Hercus. The language is related to Yita Yita Most of the tribal names of this group (Nari-Nari, Barapa Barapa, Latjilatji, Warkawarka, Watiwati, Wemba-Wemba) are formed by a reduplication of the word for 'no' in their respective languages, the word 'tati' bearing that sense.
The Tatitati lands, according to Norman Tindale, extended over 900 square miles (2,300 km2), covering the area from Euston to 15 miles (24 km) above the Murrumbidgee junction. Though mainly concentrated on the southern bank of the Murray River, they also ranged as far north as Benanee. As part of the Murray–Darling basin, the area's history of human habitation goes back some 27,000-36,000 years.
The Tatitati, mujch like the Latjilatji, were divided into two moieties, the Kailpara and Makwara, with descent from the mother's side.
