Garig-Ilgar language

Ilgar, also known as Garig-Ilgar after its two dialects, is an extinct Iwaidjan language spoken in the mainland of Cobourg Peninsula, around Port Essington, Northern Territory.

Unlike many Australian languages, Ilgar does not have lamino-alveolars.

Evans (1998) briefly discusses vowels in his paper noting that Iwaidjan languages including Ilgar have a three vowel (/a/, /i/, /u/) system typical of most Australian languages.
