User blog comment:Callumthered/Portuguese Australia?/@comment-32656-20120211074338

Portugal is really too small to be able to colonize much. And I rather doubt they'd be able to profit in Australia, too.

There's also no way at all that the Spanish would agree to such a thing. The Portugese paid that sum for a small area east of the line to be given to them. But to move the line outright? Not happening.
