Numerous initiatives are currently underway in Australia to try to prevent the dramatic loss of traditional Aboriginal languages. Teaching these languages at school is one of them. However, this process of language revival raises issues that go beyond the pedagogical framework: Is there still enough data available to save all the languages? Are there enough trained staff to provide quality teaching? Following a general presentation of these issues, I account of my own endeavour to produce a teacher's guide of Bardi, an Aboriginal language of Western Australia. Although no one doubts the benefits of saving endangered languages, the issues that crop up once "in the field" are not the only ones that might have been expected.
