You are moving off point. And Re lines on maps, Australia as a continent has a defined position without some Mason-Dixon construct.
There is a historic reason that lines have been drawn through history. Constantine, Alexander, The Hapsburgs nor Attaturk foresaw the present. Of course one has a vested interest in one's future just not as vested as self - appointed Bill Gates, Klaus Shwab, George Soros and appointed minions like Fatih, Tedros et.al.
Power is not democracy, ethics, and morals. The Big Picture - Gaia and her inhabitants need somewhat more than demagogues to attain the utopia we seek.
