Dhudhuroa was a language of northeastern Victoria.
According to Mathews (1909: 278): The Dhudhuroa was spoken by the Dyinningmiddhang tribe on the Mitta Mitta and Kiewa rivers, and along the Murray valley from Albury to Jingellic. Minyambuta, a dialect of the Dhudhuroa, was the speech of the tribes occupying the Buffalo, King, Ovens, and Broken rivers, with the tributaries of all these streams. From Jingellic eastward was the country of the Walgalu tribe, whose speech resembled partly the Dhudhuroa and partly the Dyirringan, a tongue spoken from about Nimmitabel to Bega.
Dhudhuroa appears to consist of the first syllable of the word for ‘no’ reduplicated. The word for ‘no’ is dhubalga. It is common in southeastern Australia to base language names on the word for ‘no’. The name almost certainly contains a reduced form of wurru, which means ‘mouth’ or ‘language’ in a number of Victorian languages.
The final syllable is probably -wa, which is found on quite a few other words. Thus we probably have Dhu-dhu-(wu)rru-wa.
