Documenting sociolinguistic variation in lesser-studied languages presents methodological challenges, but also offers important research opportunities. In this paper we examine three key methodological challenges commonly faced by researchers who are outsiders to the community. We then present practical solutions for successful variationist research on indigenous languages and meaningful partnerships with local communities. In particular, we draw insights from our research with Australian languages and indigenous languages of rural China. We also highlight reasons why such lesser-studied languages are crucial to the further advancement of sociolinguistic theory, arguing that the value of the research justifies the effort needed to overcome ...
