Kidney has been left fuming after former Wallabies centre Tim Horan said Ireland had "a deliberate plan to fake injuries each time there was a breakdown in play so they could slow the game down and frustrate the Wallabies".
Horan also wrote in a newspaper column that his allegations had been confirmed by Ireland assistant coach Alan Gaffney in the changing rooms after the match.
However Kidney has dismissed the claims as "incredulous".
"What I can tell you for definite is that the reporter in question (Horan) was never in the dressing room," said Kidney.
"The coach in question (Gaffney) never spoke to him, so I'll let you make your own inferences into how he feels he can quote something that was never said.
"It's incredulous and slightly scandalous that he'd try to bring one of his fellow countrymen into something that is totally untrue.
"It's for other people to have their standards in life."
