Ngiyambaa is a member of the Wiradhuric subgroup of the Pama-Nyungan
language family. It was originally spoken by the Wailwan and Wiraibon,
East Australian tribes in the geographical centre of New South Wales
between the Sandy Creek near Cobar to the north and the Willandra Creek
near Ivanhoe to the south. Now Ngiyampaa speakers live in various places
aroundd south-eastern Australia.
The language is only spoken by a handful of people, perhaps 10, and is
used mainly for traditional and cultural purposes. There are two variants
of the language: Wailwan (Wayilwan) and Wiraibon (Wangaaypuwan).
