Kaurna country is vast, covering about 7,200 square kilometres, ranging from Crystal Brook in the north, to St Vincentâ€™s Gulf in the west, Cape Jervis in the south and Mt Lofty Ranges to the east.
The Kaurna people witnessed the destruction of most of their sites of significance and their population through disease and displacement, soon after colonisation of the Adelaide plains.
The Kaurna language had long been suppressed following colonisation of South Australia. Historians believe that the Kaurna language of the Adelaide plains was most probably taken over by English in the mid eighteen hundreds. The last known fluent speaker was Ivaritji, also known as Amelia Taylor, and she died in 1929.
Kaurna language has been going through a revival from 1990 to the present time. The revival of the language has been possible through partnership of linguists, most notably Dr Rob Amery, and the Kaurna community in Adelaide. The revival of Kaurna has been assisted by historical documents, in which German Lutheran missionaries wrote a number of words, phrases and sentences between 1836 and 1858. These missionaries were Clamor SchÃ¼rmann and Christian Teichelmann.
The Kaurna language can now be studied in some schools. Jack has taught at a number of high schools, as well as through the School of Languages, to adults as students.
