Some players 'have it', he is one of them. I think Folau can be pretty special if he stays at it. He seems to be enjoying his time in Rugby so far, I seriously hope he stays at it. If he does, next year he will have to work on refining his skills a bit. If he can develop an accurate and respectable boot, and get more accustomed to defence in rugby, he will be a huge threat, provided he continues to stick at it and develop. His raw skills are exceptional in many aspects, and he has those instincts that cannot be trained. I think he can be the best Australian fullback since Chris Latham if he continues. I like Jesse Mogg, but Folau is the type of player who can play on a different level and set a team apart.
Australia just need a decent coach and inside backs reading the same script. (Cooper is too mixed, O'Connor not a standoff, maybe Foley will continue to develop. Genia, Foley, Ioane, O'Connor/Barnes, AAC, O'Connor (he is a quality wing, and there is nothing to say he can't play inside back in some situations), Folau, would be a potent threat.
