The Bidawal language was an Australian Aboriginal language, either a dialect of or closely related to the Kurnai language, formerly spoken by the Bidhawal. However, it had borrowed a number of words referring to mammals, birds and celestial bodies from Ngarigo, as well as a smaller number of words from Thawa and Dhudhuroa. The Bidawal called their own dialect (or ) ("good speech"), and that of the neighbouring Kurnai 'strangers' language'. The Kurnai, however, called their own dialect mà Âk-dhang, and that of the Bidawal kwai-thang ("rough speech"). According to Alfred William Howitt, Bidhawal is a mixture of Kurnai, Ngarigo and Yuin.
Based on historical spellings, Corey Theatre regularized the from as Pirtawal with a retroflex stop.
