Dave, Australia is not 5500 miles across as it would have to be if the flat earth map was even close to being accurate.
The distortion problems with map projections go away if the Earth is flat!
The "actual size" of continents will not determine if the earth is a globe or flat, but I think it's important to get an accurate understanding of how flat verses globe earth compares. Why say it in words when a pic or video does it so much better?
