These people then shifted to Torres Strait — maintaining established ties with Papua as well as with Austronesian speakers further east (this latter being suggested by various characteristics of the Austronesian content in Kalau Lagaw Ya) — and overlaid an Australian population in such a way that the majority of women spoke an Australian language, with a significant number, mainly men, who spoke a South-East Papuan Austronesian language, accompanied by their Papuan wives and their perhaps bilingual children. Over time, the core structure of the local mothers' language dominated, with retention of the newcomers' Papuo-Austronesian content in the appropriate cultural subsystems. In essence this would have been a 'replay' of the original settlement by Austronesian traders at Parema, with the women understanding the language of the men, but not really needing to speak it while retaining parts of their language for significant areas. The children then created a new language shift to an Australian language with a Papuan-Austronesian admixture.
