Western Australia and Western US

Australia and the US started on the East Coasts and took over westward, meaning bigger states in the West, western halves dry?  So maybe Australia looks like what the US would, if it was further underneath the water.  Tasmania as remnant of Florida.  Likewise Caribbean parallels to shapes of islands in Pacific.  Bahamas like Philippines, but those two areas the opposite.  Only Cuba showing now, since lower than Indonesia, higher up so much bigger.
