The contact between Austronesian and Papuan languages is a highly representative phenomenon in the linguistic ecology of Southeast Asia and Oceania, its evolution deeply intertwined with human migration, trade, colonial history, and modern social development. Based on a historical periodization and incorporating language contact theory, this article examines the relationship between the two languages, from initial interaction during the ancient migration period, deep integration during the pre-colonial trade period, restructuring during the colonial period, and dynamic changes in contemporary society. The analysis focuses on the core mechanisms, current characteristics, and current impacts of language contact. The study finds that the contact between the two languages was not a one-way process of osmosis, but rather a two-way adaptive process driven by survival needs and cultural exchange. The current extinction risk faced by minority Papuan languages is directly related to the robust spread of Austronesian languages in the context of globalization. This study aims to provide theoretical insights for regional language ecological conservation, offer practical insights for the preservation of endangered languages, and enrich regional case studies of language contact.
