The document discusses the relationship between Aboriginal communities and European settlers in Port Phillip, Australia. It describes how Aboriginal communities had highly ordered societies with laws and customs that were disrupted by the Europeans. The population declined by 80% due to introduced diseases. Europeans established farms and changed land practices, threatening traditional food sources. Aboriginal communities responded in various ways including attacks, sorcery, and joining the native police or gold rush for new opportunities. Later, some Aboriginal people lived on Christian missions and reserves set up by the government.
