Eastern Tasmanian
Eastern Tasmanian is the name for the Aboriginal languages of Tasmania's central eastern coast and its hinterland, above all Paredarerme, the language of the Oyster Bay and Big River people. After the Bass Strait was flooded about six millennia before the common era, these tongues developed in isolation from the Australian mainland and cannot be shown to be related to other Australian languages.
They survive only in word lists gathered in the 1830s by the government conciliator George Augustus Robinson, including 357 Oyster Bay words and 268 Big River words. British colonisation from 1803, followed by the removals to Wybalenna between 1830 and 1835, dispersed the communities that spoke them.
