I think that this is the wrong approach. His manager will remember if he is a team player, or if he likes to cause trouble. OP should nod and hire.
Since we know the OP has been misrepresented as thinking OzGuy is his favorite, is it possible that maybe OzGuy was also misrepresented to the OP? Maybe the interview schedule required him to make multiple trips back and forth between the US and Oz, and all he really asked was isn’t there some way to do the whole interview process in one trip? Having to go through long flights and jet-lag each time he had to do a step of the interview would be wearying, and also wouldn’t allow him to be at his best, as opposed to say, staying in the US for a week or two straight, and getting all the interviews done in a shorter space of time.
How it all ended up in “Just hire the guy,” I don’t know. Maybe the VP thinks the accent is really cool.
