Bungandidj is a language ofAustralia, spoken by theBungandidj people,Indigenous Australians who lived in an area which is now in south-easternSouth Australia and in south-westernVictoria. According toChristina Smith and her book on the Buandig people, the Bungandidj called their languagedrualat-ngolonung (speech of man), orBooandik-ngolo (speech of the Booandik).^[3] As of 2017, there is a revival and maintenance programme under way for the language.^[4]

Historical variants of the name include:Bunganditj,Bungandaetch,Bunga(n)daetcha,Bungandity,Bungandit,Buganditch,Bungaditj,Pungantitj,Pungatitj,Booganitch,Buanditj,Buandik,Booandik,Boandiks,Bangandidj,Bungandidjk,Pungandik,Bak-on-date,Barconedeet,Booandik-ngolo,Borandikngolo,Bunganditjngolo, andBurhwundeirtch.

Bungandidj phonology is typical of Australian languages generally, sharing characteristics such as a single series of stops (no voicing contrast) at six places of articulation, a full corresponding set of nasals, laminals at all four coronal places of articulation and two glides.^[5] Extrapolating from historical written sources and knowledge of surrounding languages, Blake posits the following consonant inventory:^[5]

• Early descriptions of Bungandidj made no distinction between the trill/flap/r/ and approximant/ɻ/ and evidence for this contrast is based on comparative evidence only. Blake transcribes both as⟨r⟩.^[5]
• Although there is no voicing distinction, stops are transcribed with voiced symbols⟨b, g, dh, d, rd⟩ in homorganic nasal-stop clusters (where voicing is expected).^[5]
• Syllable-final palatals are transcribed with the digraphs⟨yt, yn, yl⟩ to avoid a final -y being confused with a vowel.^[5]
• Historical sources include five vowel graphemes including⟨e⟩ and⟨o⟩; however, it is likely that⟨e⟩ belongs to the/i/ phoneme and⟨o⟩ belongs to the/u/ phoneme. However, Blake conservatively retains some⟨e⟩ and⟨o⟩ segments where they are consistently transcribed in this way across historical sources.

Smith (1880), on pages 138–139, records a poem written in Bungandidj :^[3]
