Both maps below show Papua New Guinea highlighted. At 6° Mercator inflates Papua New Guinea by only about 1%, so the two maps largely agree on it. Watch what the old map does to Australia beside it. That contrast is why the new world map matters.
At 6°, Papua New Guinea sits in the band the old map drew almost honestly. It is one of the regions Mercator quietly under-represented, and that is exactly what the new Equal Earth map restores.
