Reports estimate that by 2050 all of Australia’s First Nation’s languages would of died out. Before the invasion of Australia in 1788 there were an estimated 350-750 First nation languages and dialects in use in Australia. As of the 21st century 150 remain in daily use with almost all but 20 of them considered to be endangered. The largest of these groups such as Warlpiri and Tiwi retain between 1000-3000 native speakers.
