Tasmania

Tasmania, officially the Commonwealth of Tasmania (Palawa Kani: Milaythina Lutruwita) is an island country in Oceania.

Unlike Tasmania in our world (where the Tasmania is a state of Australia, and there were more Caucasian Australians than Aboriginal Australians due to the Black Wars, where most of them died), the Black Wars didn't happen, thanks to the intervention of other sapient species, so instead, the Caucasian Australians instead settle in peace with the Tasmanian Aboriginals, and thus Tasmania became independent as a British commonwealth, ruled mainly by Aboriginal Tasmanians.

Their official languages are Palawa Kani and English.
