In 1933, voters in Western Australia voted overwhelmingly to withdraw from the Commonwealth of Australia with the goal of becoming a separate dominion within the British Empire. However, the British Parliament rejected their petition because it didn't have the support of the Australian federal government and the issue was not pursued further. But what if it had gone through? I don't know enough about British or Australian politics to speculate on how this would happen, but it seems plausible with all the talk about self-determination and all that. What would be the long-term impact of having two separate dominions on the Australian continent?
