This article reports on part of a research project that was generated by an evident need to incorporate cultural knowledge in language learning within the option of a Year 12 vocationally-oriented curriculum. Language-specific research was undertaken to ascertain the intercultural knowledge in communication related to hospitality and to propose a way for this knowledge to be incorporated into the curriculum framework. Data were collected from research sites in two Indonesian towns, and one source, the kos interview role-plays, was subjected to fine discourse analysis. The results show that very specific cultural knowledge and values are expressed in the course of a kos interview, that these involve norms different from Australian norms, that these would thus need to be taught to Australian learners, and that a workable pattern of the norms can be extracted from the data and incorporated into a framework for meeting the requirements of both intercultural language learning and a vocational curriculum.
