Create a TL in which an independent nation is formed out of Western Australia by the 1900s. The entirty of the land in modern western Australia does not have to be included and may have sections of it removed in order to gain independence such as in the example map I've made below (I made the boarder without any rhyme or reason). My only stipulations are that at least the northern and western coasts remain in the independent nation. You may also give the nation a new name of your choosing.
