Because I'm a perfectionist when it comes to this kind of thing, I've been racking the internet, my several history textbooks, and my brain for a timeline that I feel is original enough and has a Pre-Columbian POD. Â I've finally decided that I want the Majapahits to sail southwards into Australia in 1370, influencing and advancing the indigenous civilization, thus creating a much more technologically savvy and united Australian empire or two to possibly establish relationships with their Indonesian, Papuan, or Maori neighbors, and maybe hold their own against England in 1788 (or the Dutch in 1642, if we're theorizing that these alternate aborigines colonized Tasmania and European-Australian migration is not somehow negated). Â I need all you more experienced writers' feedback on this honestly quite rough idea, and any tips or theories about what chaos or order that butterflies may or may not cause. Â You can be as blunt as you want, constructive criticism is always desired.
