Asked where he thought Cheika, who was angry at Poite's performance in the test at Westpac Stadium, and particularly at his alleged refusal to engage with Wallabies skipper Stephen Moore, got the information, Hansen said: "I'm not sure, you'd have to ask Mr Cheika."
Asked if he was "upset"at the allegation, Hansen said: "Oh, terribly. Terribly. Shattered. We've got to be able to talk about something better than that, surely."
Another issue which may upset Cheika further is the fact that prop Owen Franks has escaped a citing from Sanzaar after footage appeared showing his hand coming into contact with lock Kane Douglas's face in a maul. Cheika suggested it was an obvious foul play incident.
"I've seen the footage and I agree with the independent person who said there is nothing to answer for," Hansen said. "You've got to be really really careful until you see all the views. Social media, I think, were the people who alerted everyone to it and they certainly don't get all the views.
"There's a process and that process has been followed.
"In the same game you can go to two or three lineouts where they're driving and the same thing happened. It's an unfortunate byproduct, I think, of mauling, because the only way you can get there is by clambering over the top and then that creates a response.
"People try to pull them out of the way and the only thing they can use is the head area. We'll look at that and try to ensure we don't go to that area because it creates a problem but if there's no case to answer there's no case to answer."
The test was notable for the aggravation between the two teams, but Hansen said there was little in it.
"There's a fine line between being in the zone and being too much in it or not enough in it.
"I think at times people might have been overly keen but it was all push and shove ... there's nothing really in it."
