Djanggawul myths preserve accounts of a Baijini people, who are said to have preceded the Macassans. These Baijini have been variously interpreted by modern researchers as a different group of (presumably, Southeast Asian) visitors to Australia who may have visited Arnhem Land before the Macassans, as a mythological reflection of the experiences of some Yolŋu people who have travelled to Sulawesi with the Macassans and came back, or perhaps as traders from China. Yolŋu also had well-established trade routes within Australia, extending to Central Australian clans and other Aboriginal countries. They did not manufacture boomerangs themselves but obtained these via trade from Central Australia. This contact was maintained through use of message sticks, as well as mailmen – with some men walking several hundred kilometres in their work to send messages and relay orders between tribes. European contact Yolŋu had known about Europeans before the arrival of British in Australia through their contact with Macassan traders, which probably began around the sixteenth century. Their word for European, Balanda, is derived from the Makassar language via the Malay "orang belanda" (Dutch person). Nineteenth century In 1883, the explorer David Lindsay was the first colonial white to penetrate Yolngu lands for the purposes of making a survey of its resources and prospects. He trekked along the Goyder River to reach the Arafura Swamp on the western fringe of Wagilak land. In 1884, of Arnhem Land was sold by the colonial British government to cattle grazier, John Arthur Macartney. The property was called Florida Station and Macartney stocked it with cattle overlanded from Queensland. The first manager of the property, Jim Randell, bolted a swivel cannon to the verandah of the homestead to keep the Indigenous people away, while Jack Watson, the last manager of the property, reportedly "wiped out a lot" of "the blacks" living on the coast at Blue Mud Bay. During the period of Watson's management, another large massacre is recorded to have happened at Mirki on the north coast of Florida Station. The Yolngu people today remember this massacre where many people including children were shot dead. The battles between the graziers and the local population resulted in a severe depopulation of Yolngu, but the stiffness of resistance temporarily ended efforts by the intruding balanda to take over further territory, and efforts at settlement ground to a halt. Monsoonal flooding, disease and the strong resistance from the local Aboriginal
