No. (Not that I can think of anyways)
As far as I know (and I am a U.S. citizen), it only applies to U.S. citizens. Like I cannot go to Cuba. If the teams went to Cuba, they could, in theory, connect somewhere else (like Canada) before coming to the U.S. There aren't any direct flights, though, so they would have to connect through either Canada or somewhere in Latin America.
Just going to Cuba doesn't mean the Aussies can't come here. It just makes the flights a bit more tricky, I guess.
