fact, one of the major problems encountered by Europeans was the determination of the Ngarrindjeri to rebuild their camps on land claimed for grazing. Unlike the rest of Australia, the Letters Patent establishing the Province of South Australia of 1936, following the South Australia Act 1834 (or Foundation Act), which together enabled the province of South Australia to be established, acknowledged Aboriginal ownership and stated that no actions could be undertaken that would "affect the rights of any Aboriginal natives of the said province to the actual occupation and enjoyment in their own persons or in the persons of their descendants of any land therein now actually occupied or enjoyed by such natives". This effectively guaranteed the land rights of Aboriginal people under force of law; however, this was interpreted by the colonists as simply meaning Aboriginal peoples could not be dispossessed of sites they permanently occupied. In May 1839, the Protector of Aborigines William Wyatt announced publicly, "it appeared that the natives occupy no lands in the especial manner" described in the instructions. Bowing to the interests of prominent colonists and the Resident Commissioner who wanted to survey and sell the land without hindrance, Wyatt never recorded that sites were permanently in his reports on Aboriginal culture and practices. Crafts and tools The bulrushes, reeds and sedges were used for basket-weaving or making rope, trees provided wood for spears, and stones were fashioned into tools. The Ngarrindjeri were widely known as "outstanding craftsmen" specialising in basketry, matting and nets with records indicating that nets of more than long were used to catch emus. It was claimed by colonists that the nets they made for fishing were superior to those used by Europeans. The nets, made by chewing the roots of bulrush (Typha shuttleworthii) until only the fibre remained which was spun into threads by the women to be then woven into nets by the men, were "considered to be a sort of fortune to its owner". Nutrition The people were sustained by the flora and fauna for food and bush medicine. Before colonisation, there were extensive swamps and woodlands on the Fleurieu Peninsula, which provided habitat and food sources for a range of birds, fish, and other animals, included snake-necked turtles, yabbies, rakali, ducks and black swans. Flora included the native orchid (leek orchid), guinea flower and swamp wattle (Wirilda). The Ngarrindjeri were well known to Europeans for their
