Others who have studied this period have come to a different conclusion regarding the relationship between the Aboriginal people and the visiting trepangers. Anthropologist Ian McIntosh has said that the initial effects of the Macassan fishermen were "terrible", which resulted in "turmoil" with the extent of Islamic influence being "indeterminate". In another paper McIntosh concludes, "strife, poverty and domination . . is a previously unrecorded legacy of contact between Aborigines and Indonesians." A report prepared by the History Department of the Australian National University says that the Macassans appear to have been welcomed initially, however relations deteriorated when, "aborigines began to feel they were being exploited . . leading to violence on both sides".
