The WA Handbook and Nash (2007 p.c.) identify Wudjari as a Nyungar W41 dialect. See record for Noongar / Nyungar W41 for a discussion about the relationship between Noongar / Nyungar people names and language/dialect names.

Von Brandenstein (1988) reports that what is now known as the Noongar / Nyungar language emerged because of a socio-political crisis that divided a group of people previously known as the 'shell people', with the Wudjari distancing themselves from the Nungurra through linguistic engineering (metathesis of non-final syllables). This new speech variety (which acquired the name Nyungar) then spread throughout much of the south-east of WA as a result of various population movements. This would imply that the language of the Wudjari people is Noongar / Nyungar.

Kwetjman in Wurm (1994) and Gwedjman in Oates (1975) are included here on the basis of Tindale's alternative of Wudjari, 'Kwaitjman', as well as the location of Kwaitjman given by Douglas (1968), and the location of Wudjari given by Tindale. This may perhaps have been the name of the language variety spoken by the 'shell people' (both Wudjari and Nungurra divisions) prior to the split.

Of Gwedjman, Oates (1975:90) says that this could be an alternative of Goreng W5 or another Njungar W41 dialect, though there appears to be no evidence of its relationship to Goreng. The Noongar Boodjar Waangkiny Language Centre assigns the Wudjari clan to the 'Kongal-boyal - South-eastern' dialect, noting the approximate nature of 'how the original 14 recognised Noongar Clans have been drawn into 3 main dialects'.
